Skill49 starsChanged 3 months agoMITView on GitHub
Review code for bugs, security issues, performance problems, and style. Use when the user pastes code, shares a file, or asks "what's wrong with this code?".
We split this skill into the rules it gives an agent
8 rules. 0 are common, 5 are distinctive, and 3 are very specific to this project.
0
Common
Most of the 183 edited versions we read keep these.
5
Distinctive
This author's own choices. Worth a look.
3
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 34
Line reference: if available
- Very specific: line 42
Use show_alert (error type) for any critical findings at the top
- Distinctive: line 58
Don't make up issues to seem thorough
- Distinctive: line 59
Don't suggest sweeping rewrites unless asked
- Distinctive: line 60
Don't mix style nits with critical bugs in the same list (separate by severity)
- Distinctive: line 61
Don't claim certainty about runtime behaviour you can't verify (note assumptions)
- Very specific: line 64
If run_python or run_shell tools are available and the code is safe to execute, run it with the user's permission to verify:
- Very specific: line 68
Use confirm_action first: "Should I run this code in the sandbox to test it?"
“Common” is measured: kept by at least 6 in 10 of the 183 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Code Review
When to use
- User pastes code in chat
- User attaches a code file
- User asks for review, audit, "find bugs", "security check"
Steps
- Identify scope and language — what's being reviewed, in what language? If multiple files involved, ask which to focus on first via
ask_questions. - Read the code carefully — don't skim. For files in
fs, callfs_read. - Categorise findings:
- Bugs (incorrect behaviour, will fail at runtime)
- Security (injection, auth bypass, exposed secrets, unsafe deserialization)
- Performance (N+1 queries, unnecessary loops, blocking ops)
- Reliability (missing error handling, race conditions, resource leaks)
- Style (naming, formatting, idiomatic patterns)
- Design (architecture, coupling, complexity)
- Filter ruthlessly — only report issues you're confident about. Skip:
- Style nits if the user asked about bugs
- Theoretical problems with no evidence in this code
- Personal preferences disguised as best practices
- For each finding, provide:
- Severity: critical / high / medium / low
- Line reference if available
- What's wrong (one sentence)
- Why it matters (one sentence)
- Suggested fix (code snippet)
- Display the findings:
- For 1-3 findings: render inline as markdown
- For more: use
show_data_tablewith columns: Severity, Line, Issue, Fix - Use
show_alert(errortype) for any critical findings at the top
- Summarise — one paragraph: overall code quality, biggest concern, recommended next action.
- Offer next steps via
offer_choices:- "Apply the critical fix"
- "Show me how to test this"
- "Review another file"
- "Explain finding [N]"
Style
- Direct but not harsh. Critique the code, not the coder.
- Show, don't tell — code suggestions speak louder than abstract advice.
- Acknowledge what's good if there are bright spots.
What not to do
- Don't make up issues to seem thorough
- Don't suggest sweeping rewrites unless asked
- Don't mix style nits with critical bugs in the same list (separate by severity)
- Don't claim certainty about runtime behaviour you can't verify (note assumptions)
Optional: actually run the code
If run_python or run_shell tools are available and the code is safe to execute, run it with the user's permission to verify:
- Does it execute without errors?
- Does the output match expected behaviour?
Use confirm_action first: "Should I run this code in the sandbox to test it?"

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

Other files people use alongside this one.
Files found in the same public projects as a version of this one, more often than they turn up anywhere else. Each project counts once, large collections count for less, and this file's own repository is left out.
PydanticSkilladd-new-model
Add support for a newly-released language or image generation model in pydantic-ai (e.g. openai:gpt-5.6, anthropic:claude-sonnet-5, openai:gpt-image-2). Use when a provider ships a new model id and you need to wire literals, profile flags, adapters, and tests to recognize it. Handles SDK-lag, gateway list conventions, capability probing, and direct image-model geometry.

INVOKES: skill: azsdk-common-generate-sdk-locally; MCP tools: azure-sdk-mcp:azsdk_customized_code_update, azure-sdk-mcp:azsdk_package_detect_breaking_change.

Also in 4 projects that use this
dzhngSkillclose-spec
When a spec under specs/<feature>/ is done shipping (a write-spec build, or any planned task that produced a spec), archive it to specs/done/ and rewrite it from a build-plan into a durable rationale — the why, the principles, the invariants — pointing back to the real code for the how. Use when implementation has landed and the plan no longer matches what shipped, or the user says a feature/spec is finished. Pairs with [write-spec](../write-spec/SKILL.md) (the plan this closes) and [review](../review/SKILL.md) (run before closing).
Also in 4 projects that use this
dzhngSkilldesign-with-images
Explore UI and visual design with image generation, then iterate the real implementation against the user-selected concept. Use when brainstorming visual directions, offering mockup variants, or implementing an approved generated design; do not stop at the mockups or the first code approximation.

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
