At a glance
Reviews code or recent changes for bugs, security issues, performance problems and maintainability, reporting findings by severity with the reason and a fix.
- Works in 4 steps: Identify What to Review → Read the Code → Analyze → …
- Reviewing a file or pasted snippet for bugs and security issues
- Calls git
- Checking recent uncommitted changes before committing
What it does
The agent picks what to review: a file path or pasted code you provide, otherwise the output of `git diff`, and if there are no git changes it asks. It reads the full files to understand context, then checks four groups of problems: bugs and correctness (logic errors, off-by-one errors, null handling, race conditions), security (injection risks, hardcoded secrets, unsafe deserialization, path traversal, missing input validation), performance (redundant work, N+1 queries, leaks, blocking calls in async code) and maintainability (naming, complexity, missing error handling, dead code).
Findings are reported by severity as Critical, Important or Suggestions, and each one states the issue, explains why it is a problem and shows the fix. Categories with nothing to report are skipped, and if the code is clean the agent says so rather than inventing issues.
When your agent uses it
- Reviewing a file or pasted snippet for bugs and security issues
- Checking recent uncommitted changes before committing
- Auditing code quality and getting feedback on an implementation
Example prompts
- “Review src/auth/session.ts for bugs and security problems.”
- “Look over my recent changes and tell me what's critical to fix.”
- “Here's my new caching helper. Review it for performance issues.”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Identify What to Review
- Read the Code
- Analyze
- Report
What it can do on your machine
Read from SKILL.md and the folder at commit 8cbd7b7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Thorough Code Review loads about 502 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 251 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 251 words (~502 tokens).
“Review the provided code or recent changes with a focus on correctness, maintainability, and best practices.”
