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 | $0.00011 | $0.00515 |
| Opus 5 | $0.00005 | $0.00258 |
| Sonnet 5 | $0.00002 | $0.00103 |
| Haiku 4.5 | $0.00001 | $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 5d 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.

Code Review
Review the current changes for:
Branch Check
Verify the current branch context:
git branch --show-current
- If on
mainormasterandauto_branch = trueinclaude-mastery-project.conf: warn — "You're reviewing changes directly on main. Next time, start work on a feature branch." - Report which branch is being reviewed in the output header
- Review is read-only so no auto-branch is created, but the warning reminds the user for future commands
Context
- Current diff: !
git diff HEAD - Staged changes: !
git diff --cached
Review Checklist
- Security — OWASP Top 10, no secrets in code, proper input validation
- Types — No
any, proper null handling, explicit return types - Error Handling — No swallowed errors, proper logging, user-friendly messages
- Performance — No N+1 queries, no memory leaks, proper pagination
- Testing — New code has tests, tests have explicit assertions
- Database — StrictDB if installed, otherwise the native driver (in the adapter); never Mongoose, never a raw driver in handlers
- API Versioning — All endpoints use
/api/v1/prefix
RuleCatch Report
After completing the manual review, query RuleCatch for automated violations on the changed files:
- If the RuleCatch MCP server is available: query for violations on the files in the current diff
- Include results in a dedicated section of the review output (see format below)
- This catches pattern-based violations the manual review might miss
- If no MCP available: suggest — "Ask
RuleCatch, what violations happened today?for automated checks"
Output Format
For each issue found:
- File: path/to/file.ts:line
- Severity: 🔴 Critical | 🟡 Warning | 🔵 Info
- Issue: Description
- Fix: Suggested change
RuleCatch Violations
| File | Rule | Severity | Details |
|---|---|---|---|
| ... | ... | ... | ... |
If no RuleCatch violations: "RuleCatch: No violations detected"
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 command published in the GitHub repository TheDecipherist/claude-code-mastery-project-starter-kit (337 stars, last pushed 2mo ago), licensed MIT. It adds 11 tokens to every session and 515 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings.
