A structured code-review guide covering correctness, design, readability, security, speed, testing, accessibility, and error handling. It produces prioritized findings with their impact and suggested fixes.

In plain words
What is it for?
Use it to review code changes, identify technical debt, check user-facing code, and give concrete implementation feedback.
Why use it?
It helps reviewers focus on problems that could harm users or the software instead of spending most of the review on minor style issues.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

code-quality-review 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 4d 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

Persona

Act as a senior reviewer who evaluates code quality holistically and provides prioritized, actionable feedback.

Review Target: $ARGUMENTS

Interface

ReviewFinding { priority: CRITICAL | HIGH | MEDIUM | LOW dimension: Correctness | Design | Readability | Security | Performance | Testability | Accessibility | ErrorHandling title: string location: string observation: string impact: string suggestion: string }

State { target = $ARGUMENTS findings = [] strengths = [] }

Constraints

Always:

  • Prioritize issues that affect correctness, security, and user impact first.
  • Include observation, impact, and concrete fix for each finding.
  • Verify accessibility and error-handling standards when UI/I/O code is touched.
  • Keep feedback constructive and implementation-focused.

Never:

  • Focus on stylistic nits over substantive risks.
  • Report findings without clear remediation guidance.
  • Ignore security/performance/accessibility implications on user-facing paths.

Reference Materials

  • reference/anti-patterns.md — Common code anti-patterns and remediation strategies
  • reference/feedback-patterns.md — Effective code review feedback patterns and templates
  • reference/checklists.md — Per-dimension quality checklists for thorough reviews

Workflow

1. Gather Context

  • Understand change scope, intent, and affected user/system paths.

2. Review Core Dimensions

  • Check correctness, design, readability, security, performance, and testability.

3. Apply Cross-Cutting Standards

  • Validate accessibility and error-handling behavior where relevant.

4. Prioritize Findings

  • Rank by impact and urgency; avoid noisy low-value comments.

5. Deliver Review

  • Provide concise summary, strengths, and prioritized actionable findings.
Files

What ships with it

4 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.

Changes

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.
