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 | $0.00043 | $0.00515 |
| Opus 5.5 | $0.00017 | $0.00206 |
| Sonnet 5.5 | $0.00009 | $0.00103 |
| Haiku 4.5 | $0.00004 | $0.00052 |
Grade A, and why
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
Review uncommitted changes
Focus for this review, if the user gave one: $ARGUMENTS
The changes
Staged:
!git diff --staged --stat || true
Unstaged:
!git diff --stat || true
Untracked:
!git status --porcelain | grep '^??' || true
What to do
- Read the full diff. Use
git diff --stagedif anything is staged, otherwisegit diff. Read untracked files directly. - For each changed file, open the surrounding code. A change that is correct alone can still break the pattern of the module it lives in.
- Check the change against
.claude/rules/. Path-scoped rules apply to the files they match. - Search before reporting duplication. If a new helper or component looks like something that already exists, find the existing one and name it with its path.
What counts as a finding
Report only what affects correctness, security, or the stated rules:
- Dead code, commented-out blocks, or debug output left behind
- A fix that treats a symptom instead of the cause
- Logic that duplicates something already in the codebase, with the path to the original
- A hardcoded secret, an unparameterized query, unescaped user content, a missing authorization check
- A query inside a loop, or a list read with no limit
- A new behaviour with no test, or a bug fix with no regression test
Style preferences are not findings. Neither is a possible future problem.
Output
One verdict, then the findings.
- Ready to commit. Nothing blocking. Say what you checked.
- Minor issues. List them. Committing is reasonable once the author has seen them.
- Needs changes. List what must be fixed first.
Each finding gives the file and line, what is wrong, and the specific change that fixes it.
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.

review is a skill published in the GitHub repository smartwhale8/claude-playbook (43 stars, last pushed 1mo ago), licensed MIT. It adds 43 tokens to every session and 515 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
