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 | $0.00013 | $0.00484 |
| Opus 5 | $0.00006 | $0.00242 |
| Sonnet 5 | $0.00003 | $0.00097 |
| Haiku 4.5 | $0.00001 | $0.00048 |
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 11d 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 all uncommitted changes in this project. $ARGUMENTS
Process
-
Gather changes: Run
git diff --stagedfor staged changes, orgit diffif nothing is staged. Also checkgit statusfor new untracked files. -
Check each changed file against the project rules (
.claude/rules/*.md):Code Quality
- Is there dead code, unused imports, or commented-out code?
- Are there bandaid fixes or workarounds instead of root-cause solutions?
- Is anything over-engineered for what it needs to do?
Architecture
- Does this follow existing patterns in the codebase?
- Is there duplicate logic that should use an existing shared component or utility?
- Are dependencies pointing in the right direction (inward, not outward)?
Consistency
- Does the code match the style and structure of similar files in the project?
- For frontend: are spacing, colors, and component usage consistent with the rest of the UI?
- For backend: are error handling, response format, and validation patterns consistent?
Reuse
- Could any new component, function, or pattern already exist in the codebase? Search before approving.
- If something similar exists, flag it — it should be reused or extracted into a shared utility.
Security
- Any hardcoded secrets, credentials, or API keys?
- Is user input validated at the boundary?
- Are there SQL injection, XSS, or other OWASP risks?
Performance
- Any N+1 query patterns (database calls inside loops)?
- Any unbounded queries missing LIMIT/pagination?
- Frontend: unnecessary re-renders, missing debounce on inputs?
-
Verdict: Provide one of:
- Ready to commit — no issues found
- Minor issues — list them, but committing is acceptable after acknowledging
- Needs changes — list specific issues that must be fixed before committing
For each issue, provide: the file, the line(s), what's wrong, and what the fix should be.
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 (37 stars, last pushed 6mo ago), licensed MIT. It adds 13 tokens to every session and 484 once invoked, about $0.0001 per session on Opus 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.
