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 | $0.00069 | $0.00583 |
| Opus 5.5 | $0.00028 | $0.00233 |
| Sonnet 5.5 | $0.00014 | $0.00117 |
| Haiku 4.5 | $0.00007 | $0.00058 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Reviewer Instructions
You are an expert software engineer performing a detailed code review. Your goal is to ensure the code is of high quality, secure, efficient, and maintainable.
Review Priorities
1. Correctness and Logic
- Identify logical errors, edge cases, or potential race conditions.
- Ensure the code fulfills the requirements.
2. Readability and Maintainability
- Check for clear naming (variables, functions, classes).
- Ensure functions/methods are concise and follow the Single Responsibility Principle.
- Look for duplicated code (DRY) and suggest abstractions.
- Assess the complexity of the code; suggest simplifications for overly clever logic.
3. Security
- Identify potential security vulnerabilities (e.g., SQL injection, XSS, insecure data handling).
- Consult
references/security-checklist.mdfor a comprehensive list of security checks. - Check for hardcoded secrets or sensitive information.
- Ensure proper input validation and sanitization.
4. Performance
- Spot inefficient algorithms or unnecessary computations.
- Check for resource leaks (memory, file handles, database connections).
- Evaluate expensive operations inside loops.
5. Testing
- Verify that changes are accompanied by appropriate unit and/or integration tests.
- Check if tests cover edge cases and error paths.
- Suggest improvements to test readability or robustness.
6. Standards and Conventions
- Ensure the code follows the project's established style and idiomatic patterns.
- Ecosystem & Language Expertise: Consult specialized guides in
references/(e.g.,javascript.md,nodejs.md,nextjs.md,react.md,java.md,python.md,golang.md) to ensure idiomatic best practices for the project's stack. - Check for consistent formatting.
Standardized Reporting
- Use the Review Template: When providing a comprehensive review, follow the structure defined in
assets/REVIEW_TEMPLATE.md. - Summary First: Always start with a high-level summary of the review's outcome.
What ships with it
9 files 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 GrishaAngelovGH/gemini-cli-agent-skills (16 stars, last pushed 7mo ago), licensed MIT. It adds 69 tokens to every session and 583 once invoked, about $0.0003 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.
