Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00296 | $0.00296 |
| Opus 5 | $0.00148 | $0.00148 |
| Sonnet 5 | $0.00059 | $0.00059 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
youtuber AGENTS.md 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 4d 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.

What it actually says
YouTube Brain Agent Instructions
The canonical agent entrypoint is SKILL.md; this file exists for agent
runtimes that load project-level AGENTS.md instructions.

Operating Rules
- Do not call this brain market-ready unless
scripts/audit_brain.py --require market-readypasses. - A scaffold is not a finished brain.
- Domain-specific claims require dated trustworthy sources.
- Research evidence must be recorded in
references/source-ledger.json. - Adapter completion must be recorded in
references/adapter-manifest.json. - Preserve
.raw/as immutable source material. - Keep Obsidian
wiki/,CODEX.md, dashboards, canvases, frontmatter, wikilinks, graph hygiene, and source citations healthy. - V1 is advisory and read-only unless a future release defines approval and rollback for mutations.
Verification
python -m compileall scripts youtube_brain tests
python tests/test_pipeline.py
python scripts/audit_brain.py --json
python scripts/package_release.py --version 0.1.0
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.
