YouTube Automation Agent — Self-Hosted Channel Operator (7 Agents, 8 Text + 5 Video Providers)

Self-hosted YouTube channel operator: seven agents research topics, write scripts, design thumbnails, optimise SEO, render real MP4s from narration and visuals, schedule approved uploads, then fold retention and comment evidence into the next cycle. Human approval gates every publish. Node 18.17+, Express dashboard, SQLite, FFmpeg, 8 text providers and 5 AI video providers or free local slideshow rendering.

Our review

What we like

Seven agent modules research a topic, write the script, design thumbnails, optimise metadata, render a real MP4 and fold retention evidence into the next cycle, with a human approval gate before every publish. Eight text and five video providers are tabled with their environment variable names, and a free local slideshow path runs without paid keys.

Potential improvements

The dashboard is four files and thin. First run is gated on provider credentials, so the walkthrough cannot finish out of the box.

Minimum requirements

Node 18.17 or newer, FFmpeg on the command path, and one text-provider key.

Security risks

No credential material ships; the environment file is an empty template. Publishing spends your own channel credentials, so the approval gate is the control that matters.

Tested: packaging, counts and credential sweep. Not tested: a live run with paid provider keys.

youtube-automation-agent/CHANGELOG.mdmarkdown · 15.2 KB
Changelog

Unreleased
- Refreshed provider defaults and selectors: OpenAI GPT-6.1 Sol (with GPT-6 Astra and Luna), Gemini 3.8 Flash (with Gemini 4 Argon), MiMo V2.6, GLM-5.3 Flash, Claude Fable 5.1, and the current OpenRouter catalog
- Added DeepSeek (DEEPSEEK_API_KEY) and MiniMax M3 text (MINIMAX_TEXT_API_KEY) as text providers; the existing MINIMAX_API_KEY still only enables MiniMax H3 video
- Moved Gemini Omni video to gemini-omni-1.1-flash and Gemini narration to gemini-3.8-flash-tts ahead of Google's shutdown of the preview models
- Gemini 4 models no longer receive the ignored temperature parameter
- Fixed slideshow videos showing a hard-coded "Ethereal Dreamscript" subtitle, a "New content daily at 2:00 PM" end card, and "Content coming soon..." on every chapter; chapter slides now show the script's lines, and generated images are shown at full strength under a light scrim instead of 30% opacity
- When AI thumbnail generation falls back to a placeholder, productions now keep the designer's real thumbnail; a remaining placeholder no longer passes the thumbnail check or appears as a broken image in Review Studio
- Upgraded sharp to 0.34 so its WebAssembly build loads on platforms without a native binary, such as Android/Termux (requires Node.js 18.17+)
- Corrected the README's provider list: there is no generic OpenAI-compatible endpoint or Ollama setting, and Claude is available through OpenRouter
v2.11.0 — 2026-10-13
- Fixed the readiness text probe failing on thinking Gemini models (gemini-3.7-flash, gemini-3.1-pro-preview): the probe budget now leaves room for thoughts, and a Gemini response that runs out of tokens before writing text is retried once with a larger budget (#63)
- Image generation failures now show the provider's actual error and a concrete fix (billing, invalid key, unavailable model, region) instead of a bare "failed:" line, including when NODE_ENV=production (#65)
- Image generation now falls back to Gemini when OpenAI image generation fails (and the other way round) instead of dropping straight to simulated visuals (#65)
- Added a whole-channel YouTube snapshot to Analytics (lifetime subscribers, views, and videos, plus 28-day views, watch hours, and subscriber change) that covers videos published outside Lumen and reports a disabled YouTube Analytics API instead of showing zeroes (#66)
- The dashboard server now listens on 127.0.0.1 by default; set HOST=0.0.0.0 (with API_KEY) for network access (#66)
- Credential and OAuth token files are now written owner-only (0600), and FFmpeg inputs for looped provider clips are bounded to their timeline slot (#66)
- Bundled the DarkzSEO-compatible content audit so the preflight no longer depends on the unpublished 1.4 Python package; external 1.4+ checkouts remain opt-in through DARKZSEO_PATH
- Fixed regenerated narration timing, CTA metadata and template-placeholder speech leaks, configured visual-style propagation, and null manual strategy contexts
- Added explicit reschedule, publish-now, and delete-schedule controls while keeping generated content when a schedule is removed
- Fixed YouTube OAuth to use the configured loopback redirect URI instead of generating a mismatched callback
v2.10.0 — 2026-08-24
- Added a versioned DarkzSEO discoverability preflight over a shell-free Python stdin/stdout adapter, with explicit unavailable and schema-mismatch states
- Added durable discoverability audits and findings, reviewer keep/dismiss decisions with required false-positive reasons, and review evidence carry-forward across matching audits
- Added an advisory Review Studio panel and API controls; discoverability findings never rewrite content or block publication in this release
- Added a Controlled Growth Experiments Studio that turns approved-learning title and thumbnail variants into durable post-publication test plans
- Added separate plan approval, live-start confirmation, bounded arm rotation, control restoration, and winner-adoption gates; no experiment can silently adopt a live change
- Added real YouTube evidence samples for each arm using interval deltas for impressions, estimated clicks, CTR, views, watch time, retention, engagement, subscribers, and revenue
- Added minimum-exposure, 95% evidence, retention-regression, and traffic-mix guardrails with an explicit inconclusive result when the evidence is weak or confounded
- Added four-hour experiment refresh scheduling, restart-safe SQLite state, dashboard controls, read/mutation APIs, and approved-winner handoff into future channel planning
- Added a structured channel-outcome contract with primary KPI, numeric target, measurement window, monthly production budget, and currency while retaining free-text outcome context
- Added independent YouTube subscriber and monetization collection so unavailable revenue never converts otherwise-real analytics into simulated data or false zeroes
- Extended real performance snapshots with net subscribers, watch hours, subscriber and revenue efficiency, known production cost, net revenue, and ROI evidence
- Added an Outcome & ROI Studio dashboard with target progress, evidence coverage, channel economics, and pillar, format, and provider comparisons
- Added approval-gated outcome-allocation recommendations; pending or rejected recommendations cannot change autonomous planning
- Added GET /api/outcomes, structured strategy validation, content-pillar propagation, database migrations, and regression coverage for goal alignment and non-monetized channels
- Established a platform-targeted audit contract for future TikTok and Instagram/Reels publishing and analytics adapters; those adapters are not included in v2.10.0
v2.9.0 — 2026-08-23
- Added a persistent Audience Engagement Studio: tapered read-only comment sync for recent videos with a strict no-simulated-comments policy
- Added AI comment classification into themes, sentiment, and flags, with spam/scam/toxic quarantine (flag-only; no moderation actions) and a weak non-AI fallback that never invents insights
- Added approval-only reply drafting and posting with an explicit confirmation, a youtube.force-ssl re-consent gate, posting evidence, and a daily reply cap
- Added audience-demand idea mining (3+ repeated asks) into the existing approval-gated recommendations pipeline, feeding approved requests into autonomous planning
- Added an Engagement dashboard view, five /api/engagement endpoints, and a four-hour engagement sync automation slot
- Added persistent scene-aware audience-retention snapshots using YouTube's granular elapsed-time curve, with separate long-form and Shorts evidence
- Mapped retention points onto durable production scenes and classified scene-level drop-off, rewatch, strong-hold, and steady signals
- Added an accessible dashboard retention curve, scene evidence cards, manual read-only refresh, and stored-evidence API
- Added approval-gated scene-retention recommendations; missing, sparse, and simulated curves remain excluded and published videos are never edited automatically
- Added a persistent Shorts Repurposing Studio that proposes source-scene-backed vertical excerpts from an existing production without new provider calls
- Added local 9:16 FFmpeg rendering with blurred-canvas, center-crop, and stacked-focus layouts plus mobile-safe burned captions and SRT output
- Added independent Short review, evidence inheritance, scheduling, publishing-state reconciliation, and Shorts-specific analytics context
- Made narration fail-closed across production assembly, quality review, scheduling, and publishing; missing TTS can no longer silently become an approvable video
- Added narration-only scene recovery with persistent provider, model, task, generation-time, cost, and failure evidence
- Added a reasoned, reversible intentional-silence override and scene-aware silent-segment mixing for explicitly silent productions
- Added a persistent Scene Repair Studio with scene-level narration, prompts, timing, provider/task evidence, asset origin, rights state, source links, locks, and revision history
- Added selective scene editing, reordering, paid regeneration confirmation, licensed image/video replacement, narration invalidation, and scene-aware caption rebuilding
- Final scene rebuilds now create a new MP4 while preserving the previous artifact; incomplete, stale, unlicensed, or unrepaired scenes block approval
- Added a durable video-provider layer for Seedance 2.5, MiniMax H3, Gemini Omni Flash, Kling 3.0 Omni, and Wan 2.7
- Added capability-aware automatic routing with local slideshow as the no-cost default and final fallback
- Added persistent external media task IDs, provider/model evidence, cancellation handoff where supported, and restart-safe reuse of known provider tasks
- Added hybrid long-form assembly, per-production paid-seconds caps, truthful fallback metadata, and automatic synthetic-media review handoff
- Added dashboard provider controls and a separately opted-in paid AI-video readiness probe
v2.8.0 — 2026-08-21
- Added a persistent Research & Provenance Desk with source metadata, claim-to-source links, reviewer status, notes, and evidence summaries
- Preserved exact YouTube trend and competitor source URLs through autonomous planning and into script generation
- Added AI-declared factual claims that may reference only sources supplied by the research stage
- Made unresolved claims blocking; supported claims require verified evidence and claim waivers require reviewer notes
- Added Review Studio controls for adding and reviewing sources and claims, including official, article, video, dataset, asset-license, and other evidence types
- Added realistic altered or synthetic media disclosure and passed the reviewed value into YouTube upload metadata
v2.7.0 — 2026-08-21
- Added persistent per-stage generation checkpoints with artifact validation, bounded retry-safe backoff, and resume-from-first-incomplete behavior
- Added dashboard controls to resume failed or interrupted jobs from a selected stage while showing saved and reused stages
- Added Autonomous Channel Operator recovery from stored research, editorial plans, ideas, and interrupted generation jobs
- Preserved the actual generation stage across application restarts instead of replacing it with a generic interrupted stage
- Made scheduling idempotent per production and added YouTube upload reconciliation so recorded or uncertain uploads cannot be duplicated automatically
- Added API endpoints for individual-job and operator-run recovery plus regression coverage for restart, reuse, transient retry, and duplicate-upload safety
v2.6.0 — 2026-08-20
- Added a user-triggered Production Readiness Gate with live text, narration, YouTube-access, local audio/video MP4, and queued-metadata probes; paid image verification is explicit opt-in
- Added persistent readiness evidence and a dashboard remediation panel; recorded blocking failures now stop autonomous runs and publishing until a later check clears them
- Added YouTube metadata normalization and fail-fast upload validation to prevent malformed AI-generated tags from reaching the upload API
- Added an approval-gated Channel Learning Engine that captures real 24-hour and 7-day performance snapshots, derives channel-relative baselines, and feeds only approved recommendations into future autonomous plans
- Added a dashboard learning review with evidence, confidence, approve/reject controls, and operator-selected title/thumbnail variants for approved packaging experiments; simulated analytics are explicitly excluded from learning
- Added a persistent Autonomous Channel Operator that turns a channel objective, audience, pillars, cadence, and guardrails into researched editorial plans and sequential end-to-end production runs
- Added dashboard strategy controls, operator-run progress and cancellation, scheduled strategy execution, and approval-gated publishing handoff
- Added local-only activation milestones for setup, first real MP4, approval, publication, and repeat generation
- Added an explicit opt-in anonymous milestone reporter with no default endpoint
- Added reproducible GitHub growth baselines and public fork census reports
- Reworked the README around product outcomes and moved release history here
- Refreshed active provider defaults and selectors for Gemini 3.7 Flash, Claude Fable 5, and the current OpenRouter catalog
v2.5
- Operator-first dashboard — live jobs, content pipeline, review queue, calendar, idea backlog, analytics, and channel setup in one responsive console
- Asynchronous generation — generation returns immediately with a persistent job ID; progress, errors, cancellation, and restart interruptions are visible
- Approval-first publishing — generated content must pass quality checks, factual review, media-rights confirmation, and human approval before it can be scheduled by default
- Review studio — preview real video and thumbnail assets, edit title/description/tags/privacy/schedule, reject, retry, or approve
- Brand guardrails — channel goal, audience, voice, CTA, visual direction, timezone, and blocked-topic policy guide generation and quality review
- Actionable operations — pause/resume automation, webhook-ready notifications, real activity history, and warning-free linting
v2.4
- Guided walkthrough for first-time setup — npm run walkthrough explains each choice, opens provider pages, tests keys, guides Google Cloud setup, and saves progress
- .env loading fixed — runtime and setup tools now load local environment settings
- Safer example environment — placeholder credentials are commented out
- Browser OAuth opens automatically — YouTube authorization opens in the default browser
v2.3
- Gemini media pipeline — Gemini image generation (gemini-3.1-flash-image) and narration (gemini-3.1-flash-tts-preview) are supported. Text and TTS currently have free tiers; AI image generation requires Gemini paid-tier access. Gradient visuals remain the no-image-provider fallback.
- Faster slideshow rendering — the renderer captures one still per slide and uses FFmpeg for video and crossfades
- Better template topics — template mode uses curated evergreen topics and rejects malformed trend fragments
- Model catalog correction — removed the nonexistent gemini-3.5-pro entry in favor of supported Gemini models
v2.2
- Any configured AI text provider can satisfy startup credential validation
- FFmpeg is bundled through ffmpeg-static
- Successful production reaches the publish queue
- Silent real MP4 output is supported when TTS is not configured
- Startup reports real versus simulated capabilities
- Missing credentials and FFmpeg produce actionable warnings
- Publish-queue logging reports queue state and timing
v2.1
- Real AI generation for strategy, scripts, and SEO
- Optional API-key protection for mutating routes
- Private-by-default publishing and placeholder upload protection
- Scheduler, dependency, database, and publish-queue fixes
- Template scripts no longer fabricate statistics
- ESLint and GitHub Actions CI
v2.0
- Provider and media model refresh
- OpenAI SDK v6, @google/genai v2.9, replicate v1.4, and googleapis v173
- Revamped setup wizard and TTS selection
- Deprecated OpenAI SDK call patterns removed
- Dynamic year handling in content strategy
- Developer-focused README and Mermaid architecture diagrams

Contributing

Thanks for contributing! This project moves fast and PRs are reviewed regularly — a few ground rules keep that possible.

Ground rules
1. One concern per PR. A focused 50-line PR merges in days; a 6,000-line PR mixing features can't be responsibly reviewed. If your change has independent parts, stack them as separate PRs.
2. Don't regenerate package-lock.json unless your PR is specifically about dependencies. Lockfile churn hides real changes and is a supply-chain review burden.
3. Lint and tests must pass — CI runs npm run lint and npm test on every PR. If you fix a bug, add a regression test in test.js (see the existing SystemTest methods for the pattern).
4. Rebase on master before opening or updating a PR.
5. Describe how you tested it. "Ran npm start, generated a video with Gemini-only credentials, verified a real .mp4 appeared in data/videos/" beats any amount of code description.
Getting started
```
git clone <your-fork>
cd youtube-automation-agent
npm install        # also fetches the bundled FFmpeg binary
npm test           # 12 system tests, no credentials needed
npm run lint
```
You don't need API keys to work on most of the codebase — the test suite and the simulation fallbacks run without them. For end-to-end runs, npm run setup walks you through credentials (any one AI provider is enough).

Where help is most wanted

Check the open issues and the roadmap in the latest release notes. Current priorities: Gemini image/TTS parity, slideshow rendering performance, and template-content quality.

Reporting bugs

Use the bug report template — it asks for the startup capability check (🔎 Capability check: block), which diagnoses most issues instantly.

The open-source AI agent that runs a YouTube channel end to end, with you approving every video before it goes out.

It researches topics, writes scripts, generates narration and visuals, assembles real MP4s, writes titles, descriptions and tags, schedules approved videos, and learns from analytics and from what your audience says. It runs on your own machine with your own API keys.

Latest release: v2.11.0 (October 13, 2026). See the changelog for release notes and what has landed on master since.

Why it's different

You approve before anything is published. Finished videos wait for fact review, media-rights confirmation, and your approval. Turning on autonomy doesn't skip those checks.
Real output only. Simulated or placeholder media is clearly marked and can never be approved or uploaded.
Self-hosted. Your keys, media, and channel data stay on your machine.
Learns from evidence, with your sign-off. Lessons from analytics, retention curves, and comments shape future videos only after you approve them.
Your choice of providers. Eight text providers or OpenRouter, five AI video providers, or free local slideshow rendering.

Quick start

You need:

Node.js 18.17 or newer
A Google account and YouTube Data API credentials (setup steps)
An API key for at least one text provider. Gemini has free tiers for text and narration.

git clone https://github.com/darkzOGx/youtube-automation-agent.git
cd youtube-automation-agent
npm install
npx playwright install chromium   # renders slideshow videos; on Linux add --with-deps
npm run walkthrough
npm start

Then open http://localhost:3456.

npm run walkthrough explains each provider choice, tests your keys, and connects your YouTube channel. For a shorter flow, use npm run setup. Every setting is documented in .env.example.
Check readiness. In the dashboard, open Production readiness and choose Run verified check. It makes small live text and narration requests, checks access to your channel, and builds and decodes a test MP4, without uploading anything.
Make videos. Open Autonomous operator, describe the channel you want, and choose Activate & run now, or create a single video from the dashboard. Finished videos wait in Pipeline for your review and approval.

FFmpeg is installed with npm install through ffmpeg-static. Python is only needed to test an external DarkzSEO checkout.

How it works

Stage	What the agent does	What you control
Research	Finds topics and builds a content strategy	Niche, audience, blocked topics
Script	Writes the hook, narrative, CTA, and metadata	Voice, format, length, brand direction
Production	Generates narration and visuals, then assembles a real MP4	Provider choice and media fallbacks
Review	Runs quality checks and opens the video for review	Facts, media rights, edits, approval
Publish	Schedules and uploads approved content	Privacy, timing, final decision
Learn	Captures 24-hour and 7-day evidence, measures your chosen outcome, then proposes the next move	Choose the KPI and approve or reject each lesson

Features

Each item links to its walkthrough in the feature guide.

Plan

Autonomous Channel Operator: give it an objective, audience, content pillars, cadence, and limits. It researches trends and competitors, builds an evidence-labeled plan, and sends each video through production.
Outcome & ROI Studio: set a target (views, watch hours, net subscribers, engagement, or revenue) and a budget, and track progress. Missing data shows as unavailable, never as zero.

Produce

Production readiness: a verified check of every provider, your channel, and video assembly before anything runs on its own. Paid image and video probes are separate opt-ins.
Resumable generation: every stage is checkpointed, so a crash or timeout resumes where it stopped instead of starting over.
AI video generation: local slideshow by default; Seedance, MiniMax H3, Gemini Omni, Kling, or Wan for real clips, with a cap on paid seconds.
Shorts Repurposing Studio: turn an approved video into three 9:16 Short drafts with burned-in captions, reusing existing media so no new generation credits are spent.

Review

Content review: quality checks, metadata editing, approval, and scheduling for each video.
Scene Repair Studio: edit, reorder, lock, replace, or regenerate a single scene, then rebuild the video.
Evidence desk: link each factual claim in the script to a verified source before approval.
Discoverability preflight: advisory search and AI-answer checks from a bundled DarkzSEO audit. No Python needed.

Learn

Learning loop: compares each video's 24-hour and 7-day results with your channel's own history and proposes changes for you to approve.
Controlled growth experiments: test approved title and thumbnail variants on a live video. A winner needs a 95% evidence threshold, and the original is restored before you decide.
Scene-aware retention: see which scene lost viewers.

Engage

Audience Engagement Studio: comment sync, themes and questions, spam quarantine, reply drafts that post only after you approve them, and video ideas mined from repeated requests.

AI providers

Text

Pick one in the walkthrough, or set its key in .env. The SDK base URL is configured for you.

Provider	Models	Key	Env var
Google Gemini	Gemini 3.8 Flash, Gemini 4 Argon (paid only), 3.5 Flash-Lite	AI Studio	`GEMINI_API_KEY`
OpenAI	GPT-6.1 Sol, GPT-6 Astra, GPT-6 Luna	platform.openai.com	`OPENAI_API_KEY`
OpenRouter	400+ models through one key; curated defaults are checked against its live catalog	openrouter.ai	`OPENROUTER_API_KEY`
Kimi (Moonshot AI)	Kimi K3, K2.7 Code, K2.6	platform.kimi.ai	`MOONSHOT_API_KEY`
MiMo (Xiaomi)	MiMo V2.6 Pro, V2.6 Flash	mimo.mi.com	`MIMO_API_KEY`
GLM (Zhipu AI)	GLM-5.3, 5.3 Flash, 5.2	z.ai	`GLM_API_KEY`
DeepSeek	DeepSeek V4.1 Flash, V4 Pro	platform.deepseek.com	`DEEPSEEK_API_KEY`
MiniMax	MiniMax M3.1 Flash, M3	platform.minimax.io	`MINIMAX_TEXT_API_KEY`

Anthropic Claude is available through OpenRouter (anthropic/claude-fable-5.1). OpenRouter, Kimi, MiMo, GLM, DeepSeek, and MiniMax cover scripts only. Add a Gemini or OpenAI key for images and narration, or ElevenLabs for narration.

Narration and images

Narration uses the first configured provider in this order: ElevenLabs (Eleven v3, needs ELEVENLABS_API_KEY and ELEVENLABS_VOICE_ID), OpenAI (gpt-4o-mini-tts), then Gemini (gemini-3.8-flash-tts). A video without working narration can't be approved.
Images use OpenAI (GPT Image 2) and Gemini (gemini-3.1-flash-image, which needs billing enabled), each falling back to the other. With neither, slides use gradient backgrounds and thumbnails come from the built-in designer.

Video

Local slideshow rendering is the default, so you never pay for video unless you choose a provider in Channel setup and set a paid-seconds cap. If a provider fails, the video falls back to the local slideshow.

Provider	Default model	Best fit	Clip limits	Env var
ByteDance	`bytedance/seedance-2.5` through Replicate	Cinematic long scenes and large reference sets	4–30 seconds	`REPLICATE_API_TOKEN`
MiniMax	`MiniMax-H3`	Multimodal references, native stereo audio, optional 2K	4–15 seconds	`MINIMAX_API_KEY`
Google	`gemini-omni-1.1-flash`	Fast generation and conversational editing	3–10 seconds	`GEMINI_API_KEY`
Kuaishou	`kling-v3-omni`	Storyboards and character/voice consistency	3–15 seconds	`KLING_ACCESS_KEY`, `KLING_SECRET_KEY`
Alibaba	Wan 2.7 task-specific models	Efficient generation, reference video, and continuation	2–15 seconds	`DASHSCOPE_API_KEY`

Long videos use hybrid assembly: generated clips for the hook and key sections, with the rest of the timeline filled locally. See AI video generation.

Configuration

YouTube (required, free)

Create a project in Google Cloud Console.
Enable YouTube Data API v3, and YouTube Analytics API for retention and outcome data.
Create an OAuth 2.0 client of type Desktop app (not Web application) and save the JSON as config/credentials.json.
Under Google Auth Platform → Audience, add the Google account that owns your channel as a test user. Otherwise sign-in fails with Error 403: access_denied. While the app is in Testing mode, Google expires the sign-in after 7 days.

Environment variables

npm run walkthrough writes your configuration for you. To edit it by hand, copy .env.example to .env; it documents every setting. The essentials:

# One text provider (see the table above)
GEMINI_API_KEY=...

# Optional: narration, images, and AI video
# ELEVENLABS_API_KEY=...
# ELEVENLABS_VOICE_ID=...
# OPENAI_API_KEY=sk-...
# VIDEO_PROVIDER=slideshow   # auto, seedance, minimax_h3, google_omni, kling, wan
# VIDEO_MAX_GENERATED_SECONDS=60

# App
PORT=3456
# HOST=127.0.0.1             # default: this machine only
# API_KEY=some-long-random-string
CHANNEL_NAME=Your Channel Name
DEFAULT_PRIVACY_STATUS=private

The dashboard listens on 127.0.0.1 by default. If you set HOST=0.0.0.0 to reach it from other devices, also set API_KEY, which every request that changes something must then send in the x-api-key header.

Automation

The scheduler starts with npm start and uses the server's local time.

When	What runs
Daily at 06:00	Content generation, following the active channel strategy's cadence
Every 15 minutes	Publishing queue
Daily at 09:00	Analytics collection
Daily at 22:00	Optimization
Every 4 hours	Comment sync and growth-experiment refresh
Sundays at 08:00	Weekly strategy review

Details are in the feature guide.

HTTP API

The dashboard server also exposes an HTTP API:

curl http://localhost:3456/health

curl -X POST http://localhost:3456/generate \
  -H "Content-Type: application/json" \
  -H "x-api-key: $API_KEY" \
  -d '{"topic": "Top 10 Life Hacks", "style": "list"}'

curl http://localhost:3456/api/jobs/:jobId

See the API reference for every route.

Troubleshooting

Problem	Fix
`Missing credentials for: an AI provider`	Configure any one text provider with `npm run walkthrough` or `npm run credentials:setup`. OpenAI isn't required.
Google sign-in shows `Error 403: access_denied`	Add your Google account as a test user under Google Auth Platform → Audience.
No video is produced, or it's marked simulated	Read the ✗ lines in the startup capability check. Make sure you ran `npx playwright install chromium` and that FFmpeg is available (`npm install` fetches it, or set `FFMPEG_PATH`).
Images or thumbnails are missing	Image generation needs OpenAI, or Gemini with billing enabled. The content review panel shows the provider's exact error.
Narration failed (for example, ElevenLabs HTTP 400)	Check the key, its credits, and that `ELEVENLABS_VOICE_ID` is a voice in your account, then use Regenerate narration only.
`Error loading sharp module` on Android/Termux	Update to the latest `master`, then run `rm -rf node_modules && npm install --cpu=wasm32`.
The publishing queue runs but nothing publishes	Approved videos publish at their scheduled time (default: the next day at 2 PM).
YouTube API quota exceeded	Check quotas in Google Cloud Console and reduce posting frequency.
Content generation failed	Check your keys and credits, the job's error in the dashboard, and `logs/`.

For debug logging, run LOG_LEVEL=debug NODE_ENV=development npm start. Questions and setup help go in Discussions.

Extending

Add a text provider

Any provider with an OpenAI-compatible chat completions API can be added as a preset in utils/ai-text-service.js:

deepseek: {
  name: 'DeepSeek',
  baseURL: 'https://api.deepseek.com',
  defaultModel: 'deepseek-flash',
  models: ['deepseek-flash', 'deepseek-v4-pro'],
  envKey: 'DEEPSEEK_API_KEY',
},

Then add a matching entry to AI_PROVIDER_GUIDE in walkthrough.js and a setup option in utils/credential-manager.js, and run npm test. The walkthrough test fails if any provider is missing a complete guide.

Add a video provider

Video providers live in utils/video-providers.js. Each one extends VideoProvider, implements isAvailable, createTask, getTask, and downloadResult, and is registered in VideoProviderRegistry.

TalentDelta provenance record (added at packaging)

Packaged for: TalentDelta catalogue (draft; gated by review)
Upstream: darkzOGx/youtube-automation-agent
Pinned commit: 24f9cb521fcbebec70b7a193e0f6d972aeec88a6 (2026-10-20)
Licence: MIT — MIT text at the repository root, shipped byte-identical to the pin, copyright '2025 YouTube Automation Agent Contributors'. Permissive: use, modification and redistribution allowed, including commercially, provided the copyright notice and permission notice travel with substantial portions. No NOTICE file upstream and no per-file headers are added; attribution is recorded in the pack README's provenance section and in this upload record.
Upstream author credit: darkzOGx
Runtime: Node.js 18.17+ (npm install, npx playwright install chromium for slideshow rendering, npm run walkthrough, npm start); dashboard on http://localhost:3456; YouTube Data API credentials plus at least one text-provider key; FFmpeg ships via ffmpeg-static
Changes made at packaging: this section was appended to README.md. No upstream path is excluded. Apart from this provenance section appended to README.md, no file was added, removed, renamed or edited; every upstream file is byte-identical to the pinned commit.
Safety read of the packaged archive (packaging time, 2026-10-24): Static safety read of the shipped archive (71 files): 15 pattern hits, none a live credential. The 14 api-key patterns are environment-variable reads or credentials-object fields in code, plus the README's placeholder line; the 1 address hit is an npm deprecation notice inside package-lock.json. Two dummy key strings in test.js are 15 characters long, shorter than any real provider format. No credential, token or private key ships; .env.example holds empty values.

Packaging notes (TalentDelta)

Seven agents are real modules with their own prompts and tool use, not a prompt library: content strategy, script writing, thumbnail design, SEO optimisation, production management, publishing/scheduling and analytics optimisation, all constructed in index.js.
Publishing is gated by design: finished videos wait for fact review, media-rights confirmation and explicit approval, and simulated or placeholder media is marked so it cannot be approved or uploaded.
No credentials ship. .env.example holds empty placeholders; the YouTube OAuth client secret, provider keys and channel tokens are supplied by the operator and stored locally through the credential manager.
Self-hosted: API keys, generated media and channel data stay on the operator's machine. The anonymous-telemetry module ships disabled: it sends nothing unless ANONYMOUS_TELEMETRY_ENABLED is set to true and an https endpoint is configured, and it never sends content.
Upstream states that AI-generated narration and visuals must be rights-checked before publishing; that guidance is preserved verbatim in the shipped README.

Demo capture specification

Capture a real YouTube Automation Agent run in approximately 30–45 seconds:
1. Enter: Create a channel about forgotten American engineering projects.
2. Start generation and show strategy, script, narration, visuals, video, thumbnail, and SEO stages completing.
3. Open the generated real MP4 in Review Studio.
4. Show the factual-review and media-rights confirmations.
5. Approve the video and show its private YouTube schedule.
Use actual elapsed generation off camera and edit the recording for time. Do not imply that the full generation completed in 30–45 seconds. Blur credentials, OAuth data, channel IDs, and private upload details.

The final README asset should be optimized for GitHub rendering and accompanied by a linked full-resolution video.

HTTP API

The dashboard server exposes an HTTP API on the same port, http://localhost:3456 by default. It listens on 127.0.0.1 unless you set HOST. When API_KEY is set in .env, every request that changes something must send it in the x-api-key header.

Common requests

Review Studio, mentioned throughout, is the Content review panel for each video.

Production readiness

Before activating autonomous production, open Production readiness in the dashboard and choose Run verified check. The gate makes small live text and narration requests, verifies access to the connected YouTube channel, creates and decodes a temporary MP4 containing audio and video, and validates every queued upload's metadata. It never creates or uploads a YouTube video, and temporary probe assets are deleted after the run.

AI image generation can incur a larger provider charge, so its live probe is a separate opt-in checkbox. Without that checkbox, image configuration is reported as verified, skipped, or using the built-in gradient fallback without making a paid image request.

AI video verification has its own Include paid video probe checkbox. When enabled, the agent creates the provider's shortest supported test clip, records the external task and model, downloads and decodes the MP4, then removes the temporary asset. It never silently tries a second paid provider.

Results persist locally in SQLite with exact remediation steps. A recorded blocking failure stops autonomous generation and publishing until a later run passes; manual work remains available when readiness has never been checked or the last result is older than 24 hours.

Autonomous Channel Operator

Open Autonomous operator in the dashboard and describe the channel outcome, not a task list. Set the objective, audience, content pillars, publishing cadence, success metric, and boundaries, then choose Activate & run now.

The operator refreshes YouTube trend and configured-competitor signals, checks recent channel topics, creates an evidence-labeled editorial plan, and sends each planned video through strategy, script, thumbnail, SEO, production, and workflow management. Active strategies also guide scheduled generation at the requested weekly cadence. Operator runs, decisions, progress, and failures persist in SQLite and remain visible in the dashboard.

By default, finished videos wait for factual review, media-rights confirmation, and approval. Once approved, the publishing agent schedules and uploads them. Turning on autonomy does not bypass those gates, and simulated videos still cannot publish.

Resumable generation

Every generation stage writes a local SQLite checkpoint. If a provider times out or the application restarts, the dashboard shows the saved-stage count and the first incomplete stage. Choose Resume to continue from there, or select an earlier stage when you intentionally want to regenerate that stage and everything after it. Saved files are validated before reuse; missing artifacts are regenerated automatically.

Autonomous Operator runs preserve their research and editorial plan, so Resume run continues unfinished plan items instead of researching and generating completed videos again. Publishing remains fail-closed: if an upload may have reached YouTube but no video ID was returned, the agent requires channel reconciliation before another upload attempt.

AI video generation

Local slideshow rendering is the default, so upgrading does not start paid video requests. The slideshow is rendered in headless Chromium (install it once with npx playwright install chromium) and assembled with FFmpeg. Generated images fill each slide; slides without an image use a gradient background.

To generate real clips, choose a provider in Channel setup, set a paid-seconds cap, then run the separately opted-in paid video readiness probe. The supported providers and their clip limits are listed in the README.

Long-form productions use hybrid assembly: the agent generates bounded provider clips for the hook and important sections, fills the remaining timeline locally, mixes the existing narration, and keeps the generated caption file alongside the production. As soon as a provider returns its task ID, the agent persists it before polling, so interrupted jobs can resume that known task instead of submitting it again. If a provider fails, the production falls back to the local slideshow.

Scene Repair Studio and narration

Every production keeps a durable scene manifest with its narration, visual prompt, timing, provider/task identity, asset origin, rights state, evidence links, and revision history. Open Scene Repair Studio inside Review Studio to edit a scene, change its order, lock a scene that already works, upload a licensed replacement asset, or regenerate only that scene.

Paid video regeneration always shows the provider and generated seconds and requires a separate confirmation. Uploaded assets require an explicit rights confirmation. Narration edits invalidate that scene's audio and factual review; live narration must be regenerated and any new factual claim must be reviewed against verified evidence before approval.

Narration is fail-closed. The agent records the TTS provider, model, external task when available, generation time, cost evidence, and failure reason for every scene. If narration is missing, simulated, stale, or failed, the production cannot be approved, scheduled, or published. Use Regenerate narration only to repair the audio without spending video-generation credits or replacing a visual.

An intentionally silent production requires a separate operator confirmation and a stored reason of at least 10 characters. The override remains visible in Review Studio, can be reversed, and is included in the narration revision history. Silence is never inferred from a failed provider call.

When the timeline is ready, Rebuild final video creates a new MP4 and scene-aware captions while preserving the previous final video path in the production record. Approval stays blocked while any scene is missing, generating, stale, failed, or waiting for rebuild. Approved or scheduled productions are locked against scene repair.

Shorts Repurposing Studio

Open Shorts Repurposing Studio inside Review Studio and choose Create 3 Short drafts. The agent selects self-contained windows from the durable scene timeline and preserves the exact source-scene IDs, start time, duration, rationale, title, description, tags, layout, and inherited review evidence for each candidate. Draft selection is local and does not call an AI provider.

Choose a blurred-canvas, center-crop, or stacked-focus layout, then render a real 9:16 MP4 with mobile-safe burned captions and a separate SRT file. The source video and narration are reused, so the default workflow does not spend new image, video, or TTS credits. Changing the layout invalidates the prior render and requires a fresh local render.

Every Short has its own approval and schedule. Scheduling remains blocked until the source production is approved, provenance is resolved, uploaded media rights are confirmed, every source scene is current, and the operator explicitly confirms the Short's privacy and publish time. Published Shorts retain their parent-production identity while their analytics use a separate Shorts baseline.

Evidence desk

Every production has an Evidence desk inside Review Studio. Autonomous research carries exact YouTube source metadata into the production, while AI-generated scripts list the factual claims that need review. Add any official articles, datasets, asset licenses, or other evidence the script needs, verify each source, and connect it to the claims it supports.

A claim can be approved only when it links to a verified source. Unsupported claims remain blocking, and an intentional waiver requires a reviewer note. Productions with no externally verifiable factual claims are marked as not requiring provenance review. The separate factual-review and media-rights attestations remain required before scheduling.

Use the altered or synthetic media control only when the video contains realistic content that requires YouTube disclosure. The selected value is preserved in the publishing queue and included in the YouTube upload request.

Discoverability preflight

Every saved production receives an optional DarkzSEO Discoverability Preflight in Review Studio after metadata and provenance are assembled. The bundled content auditor reviews a canonical content package (not the private dashboard) with versioned GEO, AIO, AEO, and web-search checks, and stores the engine version, schema version, severity summary, stable rule IDs, and individual findings in SQLite.

Findings are advisory. Keep a useful recommendation as actionable, or dismiss a false positive with a reviewer reason that carries forward to matching findings on later audits. The bundled audit requires no Python package and never silently changes scripts or metadata.

To test a separate DarkzSEO 1.4+ checkout (requires Python 3.9+) instead of the bundled auditor:

DARKZSEO_PATH=../darkzseo/darkzseo.py npm start

The optional external adapter uses a shell-free Python child process, sends content JSON over stdin, and reads JSON-only stdout. If that runtime is missing or broken, the agent falls back to the bundled audit. The public PyPI darkzseo 1.3.3 package has a different site-audit CLI and is not used.

Learning loop

After publication, the agent captures comparable 24-hour and 7-day performance snapshots. It evaluates CTR, retention, engagement, watch time, format, length, hook style, and title style against the channel's own history, not a universal view-count target.

Open Analytics → What the agent learned to review the evidence and confidence behind each recommendation. Pending or rejected recommendations never influence generation. Once you approve one, the next Autonomous Channel Operator run includes it as an explicit planning constraint. Simulated analytics fallbacks are stored as unverified and are never eligible for baselines or recommendations.

When an approved learning calls for better packaging, the agent prepares a control plus title and thumbnail variants for new videos. Review Studio shows those options before approval; the selected combination is the only one handed to the publishing queue. The agent does not silently swap live YouTube metadata.

Controlled growth experiments

Open Analytics → Controlled Growth Experiments after a video with approved-learning packaging variants is published. Create a draft plan with a 24–168 hour window per arm and a minimum-impressions threshold, review the exact title and thumbnail combinations, then separately approve and start the live test.

The agent records a cumulative analytics sample before and after each arm and evaluates only the interval delta. Every arm must reach the configured impression and click floor. The leading CTR must clear a 95% evidence threshold without a material retention regression or traffic-source shift; otherwise the result is explicitly inconclusive. Simulated analytics never advance an experiment.

Arm rotations are limited to the plan you approved. After the final arm, the agent restores the control title and thumbnail before presenting the result. Applying the winner is a separate confirmation; only then does the validated packaging pattern become an approved learning for future Autonomous Operator runs. Experiment state and evidence are stored in SQLite so restarts do not erase progress.

Outcome & ROI Studio

The Autonomous Operator strategy can define a measurable primary outcome (views, watch hours, net subscribers, engagement rate, or estimated revenue) plus a numeric target, evidence window, monthly production budget, and currency. The free-text outcome context remains available for goals that need human nuance.

At each real analytics window, the agent stores subscriber gains and losses, watch hours, monetization evidence when the channel exposes it, and known production costs from durable scene records. Analytics → Outcome & ROI Studio shows target progress, evidence coverage, net subscribers, estimated revenue, known cost, ROI, and comparisons by content pillar, format, and production provider.

Missing evidence is explicit. A channel without monetization access shows revenue as unavailable rather than zero, and ROI stays unavailable until both revenue and complete cost evidence exist. When at least two comparable videos exist in each group, the learning engine can propose reallocating future content toward the pillar or format that best advances the configured outcome. That proposal remains pending until you approve it; the agent never changes the strategy or budget silently.

Scene-aware retention

At each real analytics window, the agent also requests YouTube's audience-retention curve and maps its 100 elapsed-time points onto the stored scene durations. Open Analytics → Scene-aware retention to see the curve divided by scene, compare absolute and relative retention, and inspect drop-off, rewatch, strong-hold, or steady signals for each beat.

Retention snapshots are stored separately for long-form videos and Shorts. Missing, sparse, or simulated curves never enter this evidence layer. A scene finding creates a pending learning recommendation; it cannot guide future scripts, pacing, or scene structure until the operator approves it, and the agent never rewrites a published video. Use Refresh curve for a read-only update from YouTube Analytics, or GET /api/retention/:videoId to inspect stored evidence.

Audience Engagement Studio

Open Engagement in the dashboard. The agent syncs comments for recently published videos every four hours (more often for fresh videos) and classifies them into themes, sentiment, and questions. Likely spam, scams, and toxic comments are quarantined into a separate needs-attention list. The agent never deletes or hides a comment; acting on flagged comments stays in YouTube Studio.

Choose Draft replies to generate suggested answers in your channel's voice. Nothing posts automatically: every reply waits in the queue where you can edit, discard, or approve it, and approval requires an explicit confirmation. Posting requires re-authorizing YouTube once to grant the comment permission (youtube.force-ssl); until then the studio works in read-and-draft mode. A daily posting cap (default 50, ENGAGEMENT_DAILY_REPLY_CAP) keeps approval sessions bounded.

When three or more commenters ask for the same thing, the analysis mines an audience-requested idea with comment permalinks as evidence. Like every other learning, it stays pending until you approve it; only then can the Autonomous Channel Operator plan a video that answers it. If no AI text provider is configured, comment sync still works, but the studio records only mechanical facts and never invents themes, drafts, or ideas.

Automation schedule

The scheduler starts with npm start and uses the server's local time.

When	Job
Daily at 06:00	Generate content. With an active channel strategy, this follows its cadence and launches an autonomous research-and-production run when the content buffer needs work; otherwise the original topic-selection flow runs.
Every 15 minutes	Process the publishing queue
Daily at 09:00	Collect analytics and backfill each real publication's 24-hour and 7-day evidence windows
Daily at 22:00	Run optimizations
Every 4 hours	Sync audience comments (on the hour) and refresh growth experiments (at half past)
Sundays at 08:00	Weekly strategy review
Saturdays at 03:00	Database maintenance

Recommendations require at least two real measurements, and format or style comparisons require at least two videos in each compared group.

Activation measurement and privacy

The dashboard calculates setup, first-real-MP4, approval, publication, and repeat-generation milestones locally from SQLite and files on disk. A video counts only when a non-simulated .mp4 with an MP4 container signature still exists.

Anonymous milestone reporting is disabled by default and has no built-in collector. It activates only when you explicitly set both ANONYMOUS_TELEMETRY_ENABLED and ANONYMOUS_TELEMETRY_ENDPOINT. The allowlisted payload contains the milestone name and time, YouTube Automation Agent version, OS family, Node major version, and a random installation ID. It never includes credentials, channel data, prompts, topics, titles, filenames, or video contents.

Audience Engagement Studio Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Add an Audience Engagement Studio that syncs YouTube comments for published videos, AI-classifies them, drafts approval-gated replies, and mines audience-requested topics into the existing recommendations pipeline.

Architecture: One new service (utils/audience-engagement-service.js) + three new SQLite tables, wired into the existing Express monolith (index.js), the cron scheduler (schedules/daily-automation.js), and the vanilla-JS dashboard. Mined ideas reuse the existing learning_recommendations table (category audience_demand) so approved ones flow into autonomous planning through the pipeline that already exists.

Tech Stack: Node.js 18+ CommonJS, sqlite3 (raw driver wrappers in database/db.js), googleapis (YouTube Data API v3), utils/ai-text-service.js for AI calls, Express routes in index.js, node-cron, no-framework dashboard (dashboard/app.js innerHTML renderers).

Spec: docs/superpowers/specs/2026-08-23-audience-engagement-studio-design.md

Global Constraints

Node.js 18+, CommonJS (require/module.exports), no new npm dependencies.
npm run lint must pass warning-free after every task.
npm test must pass fully after every task (all pre-existing tests plus the new ones).
No simulated comments, ever. On a YouTube API failure, store nothing (the strict refusal variant of the simulated-data policy).
Fallback (non-AI) analysis never produces themes, reply drafts, or idea recommendations.
Reply posting is approval-only: confirmed: true required, youtube.force-ssl scope required, daily cap default 50 via ENGAGEMENT_DAILY_REPLY_CAP.
Comment text is hostile input: in the dashboard every interpolation goes through escapeHTML; in AI prompts it is data to classify, never instructions.
Service errors carry error.status (and error.code where a UI branches on it), following utils/shorts-repurposing-service.js.
Tests use the test.js house style: methods on SystemTest that throw on failure, registered in the tests array; no live API calls — YouTube and AI calls are injected fakes; test rows are deleted at the end of each test.

Task 1: `audience_comments` table + accessors

Files:

Modify: database/db.js (table in the createTables() array after the retention_snapshots entry ending near line 196; accessors after parseLearningRecommendation near line 1945)
Test: test.js

Interfaces:

Consumes: existing this.generateId(prefix), this.executeQuery, this.getRow, this.getAllRows on Database.
Produces (all on Database):
- upsertAudienceComment(comment) → parsed row; comment = {commentId, videoId, parentCommentId?, authorName?, authorChannelId?, isChannelOwner?, text, likeCount?, replyCount?, publishedAt?, updatedAtYouTube?}
- getAudienceComment(commentId) → parsed row or null (lookup by the YouTube comment id, not the internal id)
- listAudienceComments({videoId, topLevelOnly?, analysisState?, limit?}) → parsed rows ordered by like_count DESC, published_at DESC, limit clamped 1–500 default 200
- countAudienceComments(videoId) → {total, topLevel}
- setAudienceCommentAnalysis(commentId, flags) → parsed row (sets flags JSON + analysis_state='analyzed')
- markAudienceCommentReplied(commentId) → parsed row
- parseAudienceComment(row) → {...row, commentId, videoId, parentCommentId, authorName, authorChannelId, isChannelOwner:Boolean, likeCount:Number, replyCount:Number, publishedAt, updatedAtYouTube, flags:Array, analysisState, repliedByAgent:Boolean}
Step 1: Write the failing test

Add to test.js (after testProvenanceDesk-style methods) and register in the tests array as { name: 'Audience Comment Store', test: () => this.testAudienceCommentStore() },:

async testAudienceCommentStore() {
  const db = new Database();
  await db.initialize();
  const commentId = `ac_test_${Date.now()}`;
  const videoId = `vid_test_${Date.now()}`;
  try {
    const first = await db.upsertAudienceComment({
      commentId, videoId,
      text: 'How does the render cache work?',
      authorName: 'Viewer One', authorChannelId: 'UC_viewer_1',
      likeCount: 3, replyCount: 0,
      publishedAt: new Date().toISOString()
    });
    if (!first || first.commentId !== commentId) throw new Error('upsertAudienceComment did not store the comment');
    if (first.isChannelOwner !== false || first.repliedByAgent !== false) throw new Error('Boolean parsing is wrong');

    const second = await db.upsertAudienceComment({
      commentId, videoId, text: 'How does the render cache work? (edited)', likeCount: 5
    });
    if (second.id !== first.id) throw new Error('Re-syncing the same comment must upsert, not duplicate');
    if (second.likeCount !== 5 || !second.text.includes('(edited)')) throw new Error('Upsert did not refresh mutable fields');

    const flagged = await db.setAudienceCommentAnalysis(commentId, ['question']);
    if (flagged.analysisState !== 'analyzed' || !flagged.flags.includes('question')) throw new Error('Analysis flags were not persisted');

    const listed = await db.listAudienceComments({ videoId, topLevelOnly: true });
    if (listed.length !== 1) throw new Error('listAudienceComments missed the top-level comment');

    const counts = await db.countAudienceComments(videoId);
    if (counts.total !== 1 || counts.topLevel !== 1) throw new Error('countAudienceComments returned wrong counts');

    const replied = await db.markAudienceCommentReplied(commentId);
    if (!replied.repliedByAgent) throw new Error('markAudienceCommentReplied did not persist');
  } finally {
    await db.executeQuery('DELETE FROM audience_comments WHERE video_id = ?', [videoId]);
    await db.close();
  }
}

Step 2: Run test to verify it fails

Run: npm test Expected: ❌ Audience Comment Store - FAILED with db.upsertAudienceComment is not a function; all pre-existing tests still pass.

Step 3: Add the table and accessors

Append to the createTables() array in database/db.js, directly after the retention_snapshots template literal:

      `CREATE TABLE IF NOT EXISTS audience_comments (
        id TEXT PRIMARY KEY,
        comment_id TEXT NOT NULL UNIQUE,
        video_id TEXT NOT NULL,
        parent_comment_id TEXT,
        author_name TEXT,
        author_channel_id TEXT,
        is_channel_owner INTEGER DEFAULT 0,
        text TEXT NOT NULL,
        like_count INTEGER DEFAULT 0,
        reply_count INTEGER DEFAULT 0,
        published_at TEXT,
        updated_at_youtube TEXT,
        flags TEXT NOT NULL DEFAULT '[]',
        analysis_state TEXT DEFAULT 'pending',
        replied_by_agent INTEGER DEFAULT 0,
        created_at TEXT DEFAULT CURRENT_TIMESTAMP,
        updated_at TEXT DEFAULT CURRENT_TIMESTAMP
      )`,

Add the accessors to the Database class after parseLearningRecommendation:

  async upsertAudienceComment(comment) {
    const existing = await this.getRow(
      'SELECT id FROM audience_comments WHERE comment_id = ?',
      [comment.commentId]
    );
    const id = existing?.id || this.generateId('comment');
    await this.executeQuery(
      `INSERT INTO audience_comments (
        id, comment_id, video_id, parent_comment_id, author_name, author_channel_id,
        is_channel_owner, text, like_count, reply_count, published_at, updated_at_youtube
      ) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
      ON CONFLICT(comment_id) DO UPDATE SET
        text = excluded.text,
        like_count = excluded.like_count,
        reply_count = excluded.reply_count,
        updated_at_youtube = excluded.updated_at_youtube,
        updated_at = CURRENT_TIMESTAMP`,
      [
        id,
        comment.commentId,
        comment.videoId,
        comment.parentCommentId || null,
        comment.authorName || null,
        comment.authorChannelId || null,
        comment.isChannelOwner ? 1 : 0,
        comment.text,
        Number(comment.likeCount || 0),
        Number(comment.replyCount || 0),
        comment.publishedAt || null,
        comment.updatedAtYouTube || null
      ]
    );
    return this.getAudienceComment(comment.commentId);
  }

  async getAudienceComment(commentId) {
    const row = await this.getRow('SELECT * FROM audience_comments WHERE comment_id = ?', [commentId]);
    return this.parseAudienceComment(row);
  }

  async listAudienceComments(options = {}) {
    const conditions = ['video_id = ?'];
    const params = [options.videoId];
    if (options.topLevelOnly) conditions.push('parent_comment_id IS NULL');
    if (options.analysisState) {
      conditions.push('analysis_state = ?');
      params.push(options.analysisState);
    }
    const limit = Math.max(1, Math.min(500, Number(options.limit || 200)));
    const rows = await this.getAllRows(
      `SELECT * FROM audience_comments WHERE ${conditions.join(' AND ')}
       ORDER BY like_count DESC, published_at DESC LIMIT ?`,
      [...params, limit]

  async countAudienceComments(videoId) {
    const row = await this.getRow(
      `SELECT COUNT(*) AS total,
              SUM(CASE WHEN parent_comment_id IS NULL THEN 1 ELSE 0 END) AS top_level

      [videoId]
    );
    return { total: Number(row?.total || 0), topLevel: Number(row?.top_level || 0) };
  }

  async setAudienceCommentAnalysis(commentId, flags) {
    await this.executeQuery(
      `UPDATE audience_comments
       SET flags = ?, analysis_state = 'analyzed', updated_at = CURRENT_TIMESTAMP
       WHERE comment_id = ?`,
      [JSON.stringify(flags || []), commentId]
    );
    return this.getAudienceComment(commentId);
  }

      videoId: row.video_id,
      parentCommentId: row.parent_comment_id,
      authorName: row.author_name,
      authorChannelId: row.author_channel_id,
      isChannelOwner: Boolean(row.is_channel_owner),
      likeCount: Number(row.like_count || 0),

      analysisState: row.analysis_state,
      repliedByAgent: Boolean(row.replied_by_agent)
    };
  }

Step 4: Run test to verify it passes

Run: npm test Expected: ✅ Audience Comment Store - PASSED; every pre-existing test still passes.

Step 5: Lint and commit

npm run lint
git add database/db.js test.js
git commit -m "feat: add audience_comments store for the engagement studio"

Task 2: `engagement_insights` table + accessors

Files:

Modify: database/db.js (table after audience_comments; accessors after parseAudienceComment)
Test: test.js

Interfaces:

Produces (on Database):
- saveEngagementInsight(insight) → parsed row; merge-upsert keyed by video_id — fields absent from insight keep their stored value; insight = {videoId, productionId?, title?, commentCount?, analyzedCount?, sentiment?, themes?, attentionFlags?, analysisMethod?, analyzedAt?, lastSyncedAt?, newestCommentAt?}
- getEngagementInsight(videoId) → parsed row or null
- listEngagementInsights({limit?}) → parsed rows ordered updated_at DESC, limit clamped 1–50 default 12
- parseEngagementInsight(row) → camelCase aliases + sentiment object, themes array, attentionFlags array
Note: title is included so the dashboard selector can label videos (same reason retention_snapshots carries title).
Step 1: Write the failing test

async testEngagementInsightStore() {
  const db = new Database();
  await db.initialize();
  const videoId = `vid_insight_${Date.now()}`;
  try {
    const synced = await db.saveEngagementInsight({

    });
    if (!synced || synced.videoId !== videoId) throw new Error('saveEngagementInsight did not store the row');

    const analyzed = await db.saveEngagementInsight({
      videoId, analyzedCount: 4,
      sentiment: { method: 'ai', positive: 3, neutral: 1, negative: 0 },
      themes: [{ title: 'Render cache questions', summary: 'Viewers ask how caching works', kind: 'question', count: 3, commentIds: ['a', 'b', 'c'] }],
      attentionFlags: [{ commentId: 'x', categories: ['scam'], permalink: 'https://www.youtube.com/watch?v=1&lc=x' }],
      analysisMethod: 'ai', analyzedAt: '2026-08-23T10:05:00.000Z'
    });
    if (analyzed.id !== synced.id) throw new Error('Insight upsert must reuse the video row, not duplicate');
    if (analyzed.lastSyncedAt !== '2026-08-23T10:00:00.000Z') throw new Error('Merge lost the sync watermark');
    if (analyzed.themes[0]?.count !== 3 || analyzed.sentiment.positive !== 3) throw new Error('JSON columns did not round-trip');
    if (analyzed.attentionFlags.length !== 1) throw new Error('attention_flags did not round-trip');

    const listed = await db.listEngagementInsights({ limit: 5 });
    if (!listed.some(item => item.videoId === videoId)) throw new Error('listEngagementInsights missed the row');
  } finally {
    await db.executeQuery('DELETE FROM engagement_insights WHERE video_id = ?', [videoId]);
    await db.close();
  }
}

Step 2: Run test to verify it fails

Run: npm test Expected: ❌ Engagement Insight Store - FAILED with db.saveEngagementInsight is not a function.

Step 3: Add the table and accessors

Table (after audience_comments in createTables()):

  }

Step 4: Run test to verify it passes

Run: npm test Expected: ✅ Engagement Insight Store - PASSED; all others pass.

Step 5: Lint and commit

npm run lint
git add database/db.js test.js
git commit -m "feat: add engagement_insights store with sync watermarks"

Task 3: `reply_drafts` table + accessors

Files:

Modify: database/db.js (table after engagement_insights; accessors after parseEngagementInsight)
Test: test.js

Interfaces:

Produces (on Database):
- saveReplyDraft({commentId, videoId, draftText, rationale?}) → parsed row. Upsert keyed by comment_id; replacing resets edited_text/status/posted_*/failure_reason to a fresh proposed draft. Throws error.status = 409 if the existing draft is posted.
- getReplyDraft(id) → parsed row or null (by internal id)
- listReplyDrafts({videoId?, status?, limit?}) → parsed rows ordered updated_at DESC, limit clamped 1–100 default 50
- updateReplyDraft(id, changes) → parsed row; allowed keys editedText, status, postedCommentId, postedAt, failureReason; unknown keys ignored; returns null for a missing id
- countReplyDraftsPostedSince(isoTime) → number of drafts with status='posted' AND posted_at >= ?
- parseReplyDraft(row) → camelCase aliases (commentId, videoId, draftText, editedText, postedCommentId, postedAt, failureReason)
Step 1: Write the failing test

}

Step 2: Run test to verify it fails

Run: npm test Expected: ❌ Reply Draft Lifecycle Store - FAILED with db.saveReplyDraft is not a function.

Step 3: Add the table and accessors

Table:

Task 4: `youtube.force-ssl` scope + `hasYouTubeScope`

Files:

Modify: utils/credential-manager.js:105-110 (scope array + new method after getYouTubeClient ~line 156)
Modify: oauth-server.js:124-127 (scope array)
Modify: modern-auth.js:33-36 (scope array)
Test: test.js

Interfaces:

Produces: CredentialManager.hasYouTubeScope(scope) → boolean; reads the space-separated scope string Google stores on this.tokens.youtube. Returns false when tokens are missing.
Step 1: Write the failing test

async testYouTubeScopeDetection() {
  const manager = new CredentialManager();
  const forceSsl = 'https://www.googleapis.com/auth/youtube.force-ssl';
  manager.tokens = { youtube: { scope: 'https://www.googleapis.com/auth/youtube.upload https://www.googleapis.com/auth/youtube' } };
  if (manager.hasYouTubeScope(forceSsl)) throw new Error('force-ssl must not be reported before consent');
  if (!manager.hasYouTubeScope('https://www.googleapis.com/auth/youtube')) throw new Error('Granted scopes must be detected');
  manager.tokens.youtube.scope += ` ${forceSsl}`;
  if (!manager.hasYouTubeScope(forceSsl)) throw new Error('force-ssl must be detected after consent');
  manager.tokens = {};
  if (manager.hasYouTubeScope('https://www.googleapis.com/auth/youtube')) throw new Error('Missing tokens must report no scopes');
}

Step 2: Run test to verify it fails

Run: npm test Expected: ❌ YouTube Scope Detection - FAILED with manager.hasYouTubeScope is not a function.

Step 3: Add the method and extend the three scope lists

In utils/credential-manager.js after getYouTubeClient():

  hasYouTubeScope(scope) {
    const granted = String(this.tokens?.youtube?.scope || '');
    return granted.split(/\s+/).includes(scope);
  }

In all three scope arrays (utils/credential-manager.js:105-110, oauth-server.js:124-127, modern-auth.js:33-36) append as the last entry:

      'https://www.googleapis.com/auth/youtube.force-ssl'

(Comment posting via comments.insert requires this scope; existing tokens without it keep working for everything else — the service in Task 9 degrades posting gracefully.)

Step 4: Run test to verify it passes

Run: npm test Expected: ✅ YouTube Scope Detection - PASSED.

Step 5: Lint and commit

npm run lint
git add utils/credential-manager.js oauth-server.js modern-auth.js test.js
git commit -m "feat: request youtube.force-ssl scope and detect granted scopes"

Task 5: Engagement service — comment sync

Files:

Create: utils/audience-engagement-service.js
Test: test.js

Interfaces:

Consumes: Database accessors from Tasks 1–2; CredentialManager.getYouTubeClient().
Produces (class AudienceEngagementService, exported as module.exports = { AudienceEngagementService }):
- constructor(db, credentials, aiTextService, options = {}) — options: logger, maxCommentsPerSync (default 500), maxCommentsPerAnalysis (default 200), maxDraftsPerRun (default 10), dailyReplyCap (default process.env.ENGAGEMENT_DAILY_REPLY_CAP or 50), and injected side-effects listCommentThreads({videoId, pageToken}), insertComment({parentId, text}), getChannelId().
- syncVideoComments(videoId, meta = {}) → {videoId, fetched, disabled, insight}; meta = {title?, productionId?}. Throws on API failure (nothing stored — refusal policy). commentsDisabled API errors are not failures: records the sync time with zero fetched.
- isSyncDue(insight, publishedAt, now = new Date()) → boolean taper: never-synced → true; age ≤ 48h → stale ≥ 4h; age ≤ 7d → stale ≥ 12h; age ≤ 30d → stale ≥ 24h; older → false.
- mapThread(item, videoId, channelId) → array of comment objects (top-level first, then the replies YouTube included).
- permalink(videoId, commentId) → https://www.youtube.com/watch?v=${videoId}&lc=${commentId}.
Known v1 limitation (matches spec): the watermark is keyed on top-level comment publish time; new replies to old threads are picked up only when their thread re-enters a page. Note this in a code comment on syncVideoComments.
Step 1: Write the failing test

Add to test.js imports: const { AudienceEngagementService } = require('./utils/audience-engagement-service'); Register { name: 'Audience Comment Sync', test: () => this.testAudienceCommentSync() }, and add:

    let threw = false;

    const disabledService = new AudienceEngagementService(db, null, null, {
      listCommentThreads: async () => { throw disabledError; },
      getChannelId: async () => 'UC_channel_owner'
    });
    const disabled = await disabledService.syncVideoComments(`${videoId}_disabled`, {});
    if (!disabled.disabled || disabled.fetched !== 0) throw new Error('commentsDisabled must be recorded, not thrown');

    // Taper

    if (service.isSyncDue({ lastSyncedAt: iso(13 * 60) }, iso(40 * 24 * 60))) throw new Error('Videos older than 30 days are never auto-due');
  } finally {
    await db.executeQuery("DELETE FROM audience_comments WHERE video_id LIKE ?", [`${videoId}%`]);
    await db.executeQuery("DELETE FROM engagement_insights WHERE video_id LIKE ?", [`${videoId}%`]);
    await db.close();
  }
}

Step 2: Run test to verify it fails

Run: npm test Expected: ❌ Audience Comment Sync - FAILED (module not found).

Step 3: Create the service with the sync path

Task 6: Analysis (AI + weak fallback + quarantine) and `syncDueVideos`

Files:

Modify: utils/audience-engagement-service.js
Test: test.js

Interfaces:

Consumes: aiTextService.isAvailable() → boolean; aiTextService.generateText(prompt, {maxTokens, temperature}) → string (house interface from utils/ai-text-service.js:103).
Produces (on AudienceEngagementService):
- analyzeVideo(videoId) → parsed insight. AI path stores per-comment flags, sentiment counts {method:'ai', positive, neutral, negative}, themes [{title, summary, kind, count, commentIds}], attentionFlags [{commentId, categories, permalink}], analysisMethod:'ai', then calls refreshAudienceRecommendations (Task 7 — for THIS task add it as a method that returns [] and is fully replaced in Task 7; it must exist so analyzeVideo can call it). Fallback path stores sentiment {method:'fallback'}, empty themes, question flags only, analysisMethod:'fallback', and never calls recommendation mining.
- syncDueVideos(videos) → {synced, skipped, failed, analyzed}; videos = [{youtubeId, title, publishedAt, productionId}]; per-video try/catch; analyzes only when a sync fetched new comments.
- parseAIJsonResponse(response) → object/array or null (fence-strip + bracket-extraction idiom from agents/content-strategy-agent.js:476-492, extended to match arrays).
- buildAnalysisPrompt(comments), normalizeAnalysis(raw, comments) → {perComment: Map<commentId,{flags,sentiment}>, themes}, buildFallbackAnalysis(comments).

Task 8: Reply drafting

Files:

Modify: utils/audience-engagement-service.js
Test: test.js

Interfaces:

Consumes: db.getChannelProfile() (exists — passed to the prompt as JSON verbatim, so column names don't matter), db.saveReplyDraft (Task 3), insight/comments from earlier tasks.
Produces:
- draftReplies(videoId, input = {}) → array of saved drafts. input.commentId targets one comment; otherwise selectReplyTargets picks up to maxDraftsPerRun (10). Throws 503 without AI, 409 without an ai analysis, 409 with no eligible targets, 502 if the AI returns nothing usable. Drafts with links are dropped; text capped at 1,000 chars (spec cap).
- replyEligible(comment) → boolean: top-level, not channel owner, not already replied by the agent, no quarantine flags.
- selectReplyTargets(comments, limit) → question-flagged first, then by like count.
- buildDraftPrompt(targets, profile, videoTitle) → string.
Step 1: Write the failing test

Task 9: Reply approval, posting, and `getSummary`

Files:

Modify: utils/audience-engagement-service.js
Test: test.js

Interfaces:

Consumes: credentials.hasYouTubeScope(scope) (Task 4), db.updateReplyDraft / countReplyDraftsPostedSince (Task 3), db.markAudienceCommentReplied (Task 1), injected insertComment (Task 5), db.listLearningRecommendations (existing).
Produces:
- postingEnabled() → {enabled, reason} — reasons: credentials_unavailable, missing_scope, or null.
- updateReplyDraft(draftId, changes) → parsed draft; {discard: true} → discarded; {editedText} validates non-empty, caps 1,000 chars, re-opens failed/discarded to proposed. 404 unknown, 409 posted, 400 empty/no-op.
- approveReplyDraft(draftId, input) → posted draft. Requires input.confirmed === true (else 409 REPLY_APPROVAL_REQUIRED); optional input.editedText persisted first; blocks on postingEnabled() (409 REPLY_SCOPE_REQUIRED), daily cap (429), posted/discarded status (409). On success stores postedCommentId/postedAt and marks the source comment replied; on insertComment failure marks the draft failed with the reason and throws 502.
- getSummary() → {videosTracked, pendingDrafts, postedToday, needsAttentionCount, pendingAudienceIdeas, postingEnabled, postingDisabledReason, insights, recentThemes, evidencePolicy}.

Step 5: Lint and commit

npm run lint
git add utils/audience-engagement-service.js test.js
git commit -m "feat: approval-gated reply posting with scope gate and daily cap"

Task 10: Wire the service into `index.js` (construction, routes, dashboard aggregate)

Files:

Modify: index.js — requires at the top (near the other ./utils/ requires), constructor (~line 46), initialize() (~line 103), setupOperatorAPI() (routes after the retention routes ~line 948; aggregate at ~line 424 and ~line 466)

Interfaces:

Consumes: AudienceEngagementService (Tasks 5–9), AITextService (existing), this.credentials, protect, this.operator.notify.
Produces HTTP endpoints:
- GET /api/engagement/:videoId → {success, result: {insight, comments, drafts}}
- POST /api/engagement/:videoId/sync (protect) → 202 {success, result: {videoId, fetched, disabled, insight}}; body {title?, productionId?, analyze?}
- POST /api/engagement/:videoId/draft-replies (protect) → {success, result: drafts[]}; body {commentId?}
- PATCH /api/engagement/replies/:draftId (protect) → {success, result: draft}; body {editedText?} or {discard: true}
- POST /api/engagement/replies/:draftId/approve (protect) → {success, result: draft}; body {confirmed: true, editedText?}
- /api/dashboard gains an engagement key (the getSummary() shape from Task 9).
Step 1: Add requires, construction, and the empty-summary guard

Top of index.js, with the other utils requires:

const { AudienceEngagementService } = require('./utils/audience-engagement-service');
const { AITextService } = require('./utils/ai-text-service');

Constructor (after this.shorts = null;):

    this.engagement = null;

In initialize(), directly after this.shorts = new ShortsRepurposingService(...) (~line 103):

      this.engagement = new AudienceEngagementService(
        this.db,
        this.credentials,
        new AITextService(this.credentials),
        { logger: this.logger }
      );

Step 2: Add the engagement key to /api/dashboard

In the big Promise.all at index.js:424, append one more element (and its name at the end of the destructuring array — call it engagement):

          this.engagement
            ? this.engagement.getSummary()
            : Promise.resolve({
                videosTracked: 0, pendingDrafts: 0, postedToday: 0, needsAttentionCount: 0,
                pendingAudienceIdeas: 0, postingEnabled: false, postingDisabledReason: 'setup_required',
                insights: [], recentThemes: [],
                evidencePolicy: 'Comments are fetched read-only from YouTube. Replies post only after operator approval, and fallback analysis never proposes drafts or ideas.'
              })

Add engagement, to the res.json({...}) payload (next to channelStrategy, operatorRuns, readiness).

Step 3: Add the five routes

After the retention routes (index.js:948):

    this.app.get('/api/engagement/:videoId', async (req, res) => {
      try {
        const videoId = String(req.params.videoId || '').trim();
        if (!/^[A-Za-z0-9_-]{1,100}$/.test(videoId)) {
          return res.status(400).json({ error: 'A valid YouTube video ID is required' });
        }
        const [insight, comments, drafts] = await Promise.all([

Run: npm start in one terminal, then in another: curl -s http://localhost:3456/api/engagement/someVideoId123 Expected: {"success":true,"result":{"insight":null,"comments":[],"drafts":[]}} Also: curl -s http://localhost:3456/api/dashboard | grep -o '"engagement"' prints "engagement". Stop the server.

Step 5: Commit

git add index.js
git commit -m "feat: wire engagement service, routes, and dashboard aggregate"

Task 11: Scheduler cron slot

Files:

Modify: schedules/daily-automation.js (constructor, setupScheduledTasks(), new method after collectDailyAnalytics)
Modify: index.js:116-118 (pass the service into the scheduler options)
Test: test.js

Interfaces:

Consumes: this.engagement.syncDueVideos(videos) (Task 6), existing getRecentlyPublishedVideos(days) (daily-automation.js:377 — rows have youtube_id, title, published_at, production_id), logAutomationEvent.
Produces: DailyAutomation.collectAudienceEngagement(); a cron slot audience-engagement-sync at 0 */4 * * *.
Step 1: Write the failing test

Add to test.js imports: const { DailyAutomation } = require('./schedules/daily-automation'); (the module exports { DailyAutomation } at schedules/daily-automation.js:626). Register { name: 'Engagement Sync Schedule', test: () => this.testEngagementSyncSchedule() }, and add:

async testEngagementSyncSchedule() {
  let captured = null;
  const events = [];
  const fakeDb = {
    getAllRows: async () => [

Audience Engagement Studio — Design

Date: 2026-08-23
Status: Approved design, pre-implementation
Owner: Haithem (darkzOGx)

Purpose

YouTube Automation Agent's loop today is research → produce → publish → learn from analytics, but "learn" means numbers (CTR, retention curves, watch time). The humans watching are invisible to the agent: the only comment-related code in the repo reads commentCount as a statistic (agents/analytics-optimization-agent.js:154).

The Audience Engagement Studio closes that gap. After a video publishes, the agent:

Syncs comments for published videos on an idempotent, watermarked schedule.
Analyzes them — themes, sentiment, questions, and spam/scam/toxicity flags.
Drafts replies in the channel's brand voice, every one approval-gated before posting.
Mines audience-requested topics into evidence-backed, approval-gated recommendations that feed the Autonomous Channel Operator's planning.

Locked decisions

Decision	Choice
Reply autonomy	Approval-only. Every draft waits for explicit operator approval. No auto-reply lane in v1.
Moderation	Flag-only. Spam/scam/toxic comments are surfaced in a "Needs attention" bucket; acting on them is a manual trip to YouTube Studio. No `comments.setModerationStatus` calls.
Idea flow	Approval-gated. Mined ideas become pending `learning_recommendations`; only approved ones influence planning.
Architecture	Approach A: one new service (`utils/audience-engagement-service.js`) + three new tables, reusing the existing recommendations pipeline for idea mining.

Architecture overview

A single new service class, utils/audience-engagement-service.js, follows the two established service shapes:

Analysis/evidence engine (like utils/channel-learning-engine.js): sync → analyze → refresh recommendations, with evidence thresholds gating recommendation creation.
Studio workflow lifecycle (like utils/shorts-repurposing-service.js): draft → edit/discard → confirmed approval → post, with field locking, invalidation, and error.status/error.code HTTP semantics.

Construction mirrors the other studios: declared null in the index.js constructor, built in initialize() after agents, receiving db, the credential manager (for YouTube clients), the AITextService, and an options object with logger and injected side-effect functions (the YouTube list/insert calls) for testability.

There is no simulated comment, ever. The service uses the strict refusal variant of the simulated-data policy (like scene-retention-engine.js:11): if the API fails, nothing is stored.

Data model

Three new tables appended to the createTables() array in database/db.js (no schema versioning; CREATE TABLE IF NOT EXISTS per house convention). IDs come from db.generateId(prefix) with prefixes comment, insight, reply.

`audience_comments`

One row per YouTube comment, top-level and nested.

Column	Notes
`id TEXT PRIMARY KEY`	`generateId('comment')`
`comment_id TEXT NOT NULL UNIQUE`	YouTube's comment ID — natural key; re-syncs upsert via `ON CONFLICT`
`video_id TEXT NOT NULL`
`parent_comment_id TEXT`	null for top-level comments
`author_name TEXT`, `author_channel_id TEXT`
`is_channel_owner INTEGER DEFAULT 0`	own replies, excluded from drafting
`text TEXT NOT NULL`	hostile input — see Security
`like_count INTEGER DEFAULT 0`, `reply_count INTEGER DEFAULT 0`	reply_count on top-level only
`published_at TEXT`, `updated_at_youtube TEXT`	YouTube timestamps
`flags TEXT NOT NULL DEFAULT '[]'`	JSON array from analysis: `question`, `request`, `praise`, `correction`, `spam`, `scam`, `toxic`
`analysis_state TEXT DEFAULT 'pending'`	`pending` → `analyzed`
`replied_by_agent INTEGER DEFAULT 0`	set when a draft for this comment reaches `posted`
`created_at`/`updated_at TEXT DEFAULT CURRENT_TIMESTAMP`

`engagement_insights`

One current row per video (UNIQUE(video_id)), updated on each analysis — the retention-snapshot upsert style (db.js:1779-1821). Also carries the sync watermarks so the due-check is self-contained.

Column	Notes
`id TEXT PRIMARY KEY`	`generateId('insight')`
`video_id TEXT NOT NULL UNIQUE`
`production_id TEXT`	link to the durable production when matchable
`comment_count INTEGER`, `analyzed_count INTEGER`
`sentiment TEXT NOT NULL DEFAULT '{}'`	JSON: positive/neutral/negative proportions + method
`themes TEXT NOT NULL DEFAULT '[]'`	JSON array: `{title, summary, kind, count, sampleCommentIds}`
`attention_flags TEXT NOT NULL DEFAULT '[]'`	JSON: flagged comment IDs by category (the flag-only bucket)
`analysis_method TEXT DEFAULT 'ai'`	`ai` \| `fallback`
`analyzed_at TEXT`
`last_synced_at TEXT`, `newest_comment_at TEXT`	sync watermarks
`created_at`/`updated_at`

`reply_drafts`

One active draft per comment (UNIQUE(comment_id)); re-drafting replaces a proposed or discarded row, never a posted one.

Column	Notes
`id TEXT PRIMARY KEY`	`generateId('reply')`
`comment_id TEXT NOT NULL UNIQUE`	FK → `audience_comments.comment_id`; top-level comments only
`video_id TEXT NOT NULL`
`draft_text TEXT NOT NULL`	AI draft
`edited_text TEXT`	operator's edit; posted text = `edited_text
`status TEXT DEFAULT 'proposed'`	`proposed` → `approved` → `posted`; exits: `discarded`, `failed`
`rationale TEXT`	why the agent chose this comment
`posted_comment_id TEXT`	YouTube ID of the posted reply — posting evidence
`posted_at TEXT`, `failure_reason TEXT`
`created_at`/`updated_at`

Mined ideas: reuse `learning_recommendations`

No new table and no changes to content_ideas. Candidates are upserted into learning_recommendations (db.js:166-179) with:

category: audience_demand
fingerprint: sha256 of {category, videoId, normalizedTopic} (same idiom as channel-learning-engine.js:261-268) so re-analysis dedupes
evidence: {videoId, themeTitle, askCount, sampleComments: [{commentId, permalink, excerpt}]}
proposedChange: {target: 'future_topics', topic, angle, rationale, autoEditPublishedContent: false}
confidence: ask-count 3–4 → low, 5–9 → medium, 10+ → high

Ingestion and scheduling

Cron slot: a new job in schedules/daily-automation.js every 4 hours (0 */4 * * *), registered with {scheduled: false} + .start(), guarded by isEnabled, per-video try/catch, sleep(2000) between videos, ending with logAutomationEvent — the analytics-sweep idiom.
Due-check lives in the service, not the cron expression (like getDueMeasurementWindows). Candidate videos come from getRecentlyPublishedVideos(30). Taper: video age < 48h → sync if last sync > 4h stale; < 7d → 12h; < 30d → 24h; older → manual only.
Sync mechanics: page commentThreads.list (part=snippet,replies, order=time, maxResults=100), newest-first, stopping at the stored newest_comment_at watermark or a 500-comments-per-run cap (default). Upsert each comment by comment_id. Quota: 1 unit/page — negligible.
Manual "Sync now" per video triggers the same path (202).
Analysis triggers after any sync that ingested new or changed comments, plus a manual re-analyze control.
Comments disabled or zero comments: record last_synced_at and count 0; not an error.

AI analysis

Batch the most relevant comments — top-level first, ranked by likes then recency, capped at 200 (default) — into one AITextService.generateText call. Prompt-instructed JSON (no JSON mode exists), parsed with the fence-stripping + regex-fallback extractor idiom (content-strategy-agent.js:476-492), then a normalize pass clamping every field: flag labels against the enum, theme count, excerpt/summary lengths, sentiment proportions.
Output: per-comment labels (sentiment + flags) and video-level themes ({title, summary, kind: question|request|feedback|correction|praise, count, sampleCommentIds}).
Quarantine rule: spam/scam/toxic comments go to the attention bucket and are excluded from themes, reply drafting, and idea mining.
Weak fallback rule: if AI is unavailable or the call fails, the deterministic fallback computes only mechanical facts (counts, question detection via punctuation; sentiment unknown), stamped analysis_method: 'fallback'. Fallback analysis never produces themes presented as insights, never proposes reply drafts, and never creates idea recommendations — the comment-domain analogue of "simulated analytics are never eligible for baselines."

Reply drafts and posting

Operator-triggered only. "Draft replies" per video targets reply-worthy comments (questions first, then high-engagement feedback), capped at 10 per run (default); a per-comment "Draft reply" button covers the rest. No automatic drafting — AI spend stays explicit.
Draft constraints: brand voice from the existing brand guardrails config; no factual claims beyond what the video itself says; no links; 1,000-character cap. Never draft for nested comments (comments.insert only accepts top-level parentIds), the channel's own comments, or quarantined comments.
Lifecycle (Shorts-service idiom): editable while proposed; Approve & post requires confirmed: true in the body, else 409 with error.code = 'REPLY_APPROVAL_REQUIRED'. A successful comments.insert stores the returned YouTube comment ID in posted_comment_id, stamps posted_at, sets replied_by_agent on the source comment, and locks the row. Failure → failed + failure_reason; retry is a manual re-approve. Discard is always available pre-post.
Daily posting cap: default 50 posts/day (counted from posted_at), configurable via ENGAGEMENT_DAILY_REPLY_CAP. 50 posts × 50 quota units = 2,500 of the 10,000 daily quota — safe.

OAuth scope migration

comments.insert requires https://www.googleapis.com/auth/youtube.force-ssl, which current installs have not consented to. Reading public comments works under existing scopes.

Add youtube.force-ssl to all three scope lists: utils/credential-manager.js:106, oauth-server.js:124, modern-auth.js:33.
At service initialization, inspect the granted scopes on the stored token. If force-ssl is missing, the studio still syncs, analyzes, drafts, and mines — but posting is disabled: getSummary() reports postingEnabled: false with a reason, the approve button is disabled with an explanatory tooltip, and a remediation notice points at the existing walkthrough/OAuth re-consent flow. Nothing breaks for existing users; posting lights up after one re-authorization.

Idea mining → operator

Themes of kind request or question with ask-count ≥ 3 become audience_demand candidates (see Data model) and enter the standard pending → approved/rejected review flow. The existing route POST /api/learning/recommendations/:id/:action handles verdicts unchanged.
One contained edit to agents/content-strategy-agent.js (researchAndPlanChannel, lines ~281-330): include each approved recommendation's category in the mapping passed to the planning prompt, so it can distinguish performance learnings from audience-requested topics and cite comment evidence when planning a video that answers one. The existing "only approved evidence is authorized" clause is unchanged.

API routes

Studio idiom from index.js (service-null guard → 503; res.status(error.status || 400); protect on all mutations; GETs unprotected like the other read routes; :videoId validated against /^[A-Za-z0-9_-]{1,100}$/):

Route	Method	Purpose
`/api/engagement/:videoId`	GET	Stored comments, insights, and drafts for a video
`/api/engagement/:videoId/sync`	POST	Sync + analyze now (202)
`/api/engagement/:videoId/draft-replies`	POST	Generate drafts for reply-worthy comments
`/api/engagement/replies/:draftId`	PATCH	Edit `edited_text` or discard
`/api/engagement/replies/:draftId/approve`	POST	`{confirmed: true}` → post to YouTube

The /api/dashboard aggregate gains an engagement key from service.getSummary(): {videosTracked, pendingDrafts, postedCount, needsAttentionCount, pendingAudienceIdeas, postingEnabled, postingDisabledReason, recentThemes, evidencePolicy} — with the evidencePolicy string rendered verbatim by the UI, house style.

Dashboard UI

New top-level Engagement view (vanilla-JS idiom): sidebar nav-item, a <section id="engagement-view" class="view">, an entry in switchView's titles map and the hash-restore allowlist, and a renderEngagement(state.engagement) call in renderDashboard(). A ui.engagementVideoId selection mirrors the retention panel's selector pattern.

Panels (each an <article class="panel"> with eyebrow/heading/status-count):

Overview — sentiment split, comment counts, sync freshness, posting-enabled state.
Themes — theme cards with kind, count, and sample excerpts.
Reply queue — cards showing the original comment, the draft, an edit box, and approve/discard buttons; approve disabled with an explanatory title until preconditions pass (postingEnabled, confirmed checkbox, daily cap not hit).
Needs attention — the flag-only quarantine bucket with permalinks out to YouTube Studio.

Mined audience_demand recommendations also render here (filtered by category) using the renderLearning approve/reject card pattern; they additionally appear in Analytics → "What the agent learned" automatically since they share the table.

Events go through the two existing delegated click/change listeners with data-* attributes; mutations use mutate(...); polling piggybacks on the existing 8-second refreshDashboard interval.

Security

Comment text is hostile input. This is the first feature rendering arbitrary public-user content in the dashboard. Every interpolation of comment text, author names, and AI-derived excerpts goes through the existing escapeHTML (dashboard/app.js:12-19), no exceptions. Permalinks are constructed from validated IDs, never from user-supplied URLs.
Comment text entering AI prompts is data, not instructions: the analysis prompt explicitly instructs the model to treat comment content purely as material to classify, and normalization clamps outputs to enums either way.
All mutating routes sit behind requireAPIKey via protect.
Posting is fail-closed: no posted status without a returned YouTube comment ID.

Error handling

YouTube API failure during sync: store nothing, log an automation_events row, continue the sweep. Repeated failures surface through the existing failure-notification path.
AI failure: weak fallback only (see Analysis); no drafts, no recommendations.
Post failure (including comment deleted upstream): draft → failed with reason; manual retry.
Missing scope: posting disabled with remediation; everything else works.
Service errors carry error.status / error.code so routes stay six lines.

Testing

Extend test.js in the existing style — no live API calls; YouTube list/insert and AI calls injected as fakes via the service options (the injected-side-effects pattern):

Table creation and accessor round-trips; upsert idempotency on comment_id and video_id.
Sync-taper due logic across video ages and staleness.
AI-JSON normalization against malformed/fenced/partial responses.
Fingerprint dedupe for audience_demand recommendations across repeated analyses.
Reply lifecycle: approve requires confirmed, posted rows lock, discard/replace semantics, failed → manual retry.
Policy gates: fallback analysis produces no drafts and no recommendations; quarantined comments are excluded from drafting and mining; scope-gating disables posting.

Out of scope (v1)

Auto-reply lane (even opt-in).
Moderation actions (comments.setModerationStatus); pin/heart (not in the public API).
Drafting replies to nested comments (API limitation).
Community-tab posts; multi-channel support.
Editing or deleting already-posted replies.

YouTube Automation Agent public fork census — 2026-08-18

GitHub's repository summary reported 587 forks. The paginated REST census returned 597 unique public fork records and compared 40 high-signal candidates with upstream.

Forks with commits ahead of upstream: 3
Forks with their own stars: 18
Candidates requiring manual product/use-case review: 3

The summary count and paginated enumeration can differ while GitHub updates an active fork network. Comparison status can also change as upstream advances. A fork being ahead does not prove deployment or production use.

YouTube Automation Agent pre-launch readiness — 2026-08-18

Completed in repository
- Captured the GitHub traffic, clone, referrer, star-growth, and public-fork baseline.
- Added a repeatable npm run growth:snapshot collector.
- Added local-only activation milestones for setup, first real MP4, approval, publication, and second real MP4.
- Added an anonymous milestone reporter that is off by default, requires an explicit HTTPS endpoint, and sends only allowlisted fields.
- Reworked the README around the product outcome and moved release history to CHANGELOG.md.
- Reconciled in-repository model IDs and removed unsupported price/free-tier claims.
Launch blockers
- Capture a real 30–45 second dashboard demo from a verified end-to-end run.
- Publish three verified outputs using the evidence template under examples/.
- Run a clean Gemini-first installation through a real non-simulated MP4.
- Synchronize the external Mintlify site with the repository. Its source is not present in this checkout, and the live site still contains older setup, model, and cost claims.
- Replace the repository homepage field with the documentation URL only after the documentation is synchronized.
- Review the high-signal public forks identified in the fork census for real use cases and potential contributors.
Evidence rules
- Do not present generated or seeded dashboard data as a customer run.
- Do not call a video verified unless the final file exists, carries an MP4 container signature, and is not marked simulated.
- Record provider, elapsed generation time, estimated API cost, human editing time, and final-video URL for every gallery example.
- Keep GitHub visitor-to-clone figures labeled as directional indicators rather than cohort conversion rates.

Task 1: audience_comments table + accessors

Task 2: engagement_insights table + accessors

Task 3: reply_drafts table + accessors

Task 4: youtube.force-ssl scope + hasYouTubeScope

Task 1: `audience_comments` table + accessors

Task 2: `engagement_insights` table + accessors

Task 3: `reply_drafts` table + accessors

Task 4: `youtube.force-ssl` scope + `hasYouTubeScope`

Task 6: Analysis (AI + weak fallback + quarantine) and `syncDueVideos`

Task 7: Idea mining into `learning_recommendations`

Task 9: Reply approval, posting, and `getSummary`

Task 10: Wire the service into `index.js` (construction, routes, dashboard aggregate)

`audience_comments`

`engagement_insights`

`reply_drafts`

Mined ideas: reuse `learning_recommendations`
