Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

youtube-brain scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

YouTube Brain

Operate the vault first. Read CODEX.md, wiki/hot.md, and wiki/index.md before changing notes.

Commands

/youtube-brain new <client-slug> --owner <name>
/youtube-brain ingest --vault <path> --file <source>
/youtube-brain synthesize --vault <path>
/youtube-brain report --vault <path>
/youtube-brain visuals --vault <path>
/youtube-brain lint --vault <path>
/youtube-brain next --vault <path>

Source checkout equivalent:

youtube-brain new <client-slug> --owner <name>
youtube-brain ingest --vault <path> --file <source>
youtube-brain synthesize --vault <path>
youtube-brain report --vault <path> --html-only

Required Operating Rules

  1. Read <vault>/CODEX.md.
  2. Read <vault>/wiki/hot.md.
  3. Read <vault>/wiki/index.md.
  4. Preserve .raw/ as immutable source material.
  5. Never store credentials in the vault.
  6. Never make domain-specific claims without dated trustworthy sources.
  7. Keep hot, index, overview, and log current.
  8. Record research evidence in references/source-ledger.json.
  9. Record domain adapter completion in references/adapter-manifest.json.

Script Mapping

  • new -> python scripts/scaffold_vault.py
  • ingest -> python scripts/ingest_source.py
  • synthesize -> python scripts/synthesize_brain.py
  • report -> python scripts/render_brain_report.py
  • visuals -> python scripts/generate_vault_visuals.py
  • lint -> python scripts/lint_vault.py
  • next -> python scripts/guide_next_action.py

Quality Gates

  • No growth, revenue, or monetization claim without a current official or primary source
  • No credentials, OAuth tokens, cookies, earnings, or private audience data in repo artifacts
  • No sub4sub, bot engagement, engagement bait, or platform-policy-violating tactics
  • No account mutation or upload automation without explicit owner approval and an audit trail
  • No irreversible recommendation without owner, confidence, source, and rollback note

Do not call this brain market-ready unless scripts/audit_brain.py --require market-ready passes. A scaffold is not a finished brain.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
