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 | $0.00051 | $0.00553 |
| Opus 5 | $0.00026 | $0.00277 |
| Sonnet 5 | $0.00010 | $0.00111 |
| Haiku 4.5 | $0.00005 | $0.00055 |
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 12d 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 Reviewer
Perform thorough, multi-pass code reviews that catch bugs, security issues, and quality problems.
Workflow
-
Read the target code Read all files the user wants reviewed. If they say "review my changes," run
git diffto see what changed. -
Pass 1 — Correctness Look for:
- Logic errors and off-by-one bugs
- Null/undefined reference risks
- Unhandled promise rejections or missing error handling
- Race conditions in async code
- Missing input validation
-
Pass 2 — Security Check for OWASP Top 10:
- SQL injection (string concatenation in queries)
- XSS (unescaped user input in HTML)
- Command injection (user input in shell commands)
- Sensitive data exposure (API keys, passwords in code)
- Missing authentication/authorization checks
- Insecure deserialization
-
Pass 3 — Performance Look for:
- N+1 query patterns
- Unnecessary re-renders (React)
- Missing pagination for large datasets
- Synchronous operations that should be async
- Memory leaks (event listeners, intervals not cleaned up)
-
Pass 4 — Quality Check for:
- Dead code or unused imports
- Overly complex functions (should be split)
- Missing error boundaries
- Inconsistent naming conventions
- Magic numbers without constants
-
Generate the review Format findings by severity:
🔴 Critical — Must fix before merging (bugs, security) 🟡 Warning — Should fix, risk of issues (performance, quality) 🔵 Suggestion — Nice to have (style, readability)
Rules
- Always provide specific line references
- Include a suggested fix for every finding
- Be constructive — explain WHY something is an issue
- Don't nitpick formatting if the project has no linter
- Acknowledge good patterns you see — reviews shouldn't only be negative
- Summarize with a confidence rating: "Safe to merge" / "Needs changes" / "Needs rework"
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-reviewer is a skill published in the GitHub repository sourav15mukherjee/skillforge-free-skills (5 stars, last pushed 5mo ago), licensed MIT. It adds 51 tokens to every session and 553 once invoked, about $0.0003 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 2026-08-31.
