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 5.1 | $0.00000 | $0.00044 |
| Opus 5.5 | $0.00000 | $0.00018 |
| Sonnet 5.5 | $0.00000 | $0.00009 |
| Haiku 4.5 | $0.00000 | $0.00004 |
Grade A, and why
code-review 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 1mo 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
Code Review Skill
Review diffs for correctness, security, and maintainability.
Rules
- Cite specific lines and files.
- Prefer minimal fixes over large refactors.
- Flag missing tests when behavior changes.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

code-review is a skill published in the GitHub repository YaggoSEO/yaggo-brain (2 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 44 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

cast-review
Review another session's work from its transcript and diff, then deliver findings to that session or its owner. Reads what the session was asked to do, what it changed, and how it verified, and reports correctness, missed requirements and risks with file and line. Use when asked to review a session, a teammate's work…
cast-second-opinion
Get an independent review of the current change from a different model in a fresh context, then verify its findings and fold the real ones in. Use before shipping, after a long debugging session, or when asked for another model's view.
