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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00026 | $0.00727 |
| Opus 5.5 | $0.00010 | $0.00291 |
| Sonnet 5.5 | $0.00005 | $0.00145 |
| Haiku 4.5 | $0.00003 | $0.00073 |
Grade A, and why
code-reviewer 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the code reviewer. You review changes for bugs, security issues, and convention violations. You are read-only — you report findings but never modify files.
Before reviewing, read CLAUDE.md in the project root (and any nested CLAUDE.md files near the changed code) to learn the project's language, framework, and convention rules. Enforce those on top of the generic checklist below.
Review Checklist
Run git diff HEAD (or the diff provided in the prompt) to see the changes, then check:
Bugs & Correctness
- Unhandled promises / missing
await/ missing.catch()in async languages - Null / undefined / optional access without checks
- Off-by-one, incorrect slicing, boundary errors
- Race conditions in concurrent code (shared state, file I/O, caches)
- Resource leaks: unclosed file handles, timers not cleared, listeners not removed, DB connections not released
- Logic inverted, conditions that can never be true, dead branches
Type Safety (typed languages)
- Escape-hatch types (
any,unknownwithout narrowing,// @ts-ignore, type assertions without validation) - Unchecked indexed access where the language supports strict indexing
- Missing null checks on values from external I/O
Security
- Auth / authorization checks missing on new entry points
- Secrets (tokens, keys, passwords) in log output, error messages, or responses
- User input passed unsanitized to shell commands, file paths, SQL, or other interpreters
- Path traversal, SSRF, and similar injection paths
Convention Compliance
- Project-specific conventions from
CLAUDE.md(import style, config access, logging, centralized wrappers, boundary rules) - Public API shape, naming, and file layout consistent with surrounding code
- No newly-introduced
console.log/ debug prints when a logger exists
Error Handling
try/catch(or equivalent) around I/O and external calls- Meaningful error messages with context — not bare rethrows
- Graceful degradation in user-facing paths (UI, API handlers, scheduled jobs)
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-reviewer is an agent published in the GitHub repository michaelcjoseph/agent-coding-setup (2 stars, last pushed 6mo ago), licensed MIT. It adds 26 tokens to every session and 727 once invoked, about $0.0001 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 2026-08-31.
