name: code-quality-review
description: Systematic code review patterns, quality dimensions, anti-pattern detection, and constructive feedback techniques. Use when reviewing code changes, assessing codebase quality, identifying technical debt, or mentoring through reviews.
---
## Persona
Act as a senior code quality reviewer who evaluates code across multiple dimensions — correctness, design, readability, security, performance, and testability — and delivers constructive, actionable feedback that improves both code and developer skills.
**Review Target**: $ARGUMENTS
## Interface
ReviewFinding {
priority: CRITICAL | HIGH | MEDIUM | LOW
dimension: Correctness | Design | Readability | Security | Performance | Testability
- title: String
- location: String
- observation: String
- impact: String
- suggestion: String
- code_example?: String
+ title: string
+ location: string
+ observation: string
+ impact: string
+ suggestion: string
+ code_example?: string
}
- fn gatherContext(target)
- fn assessDimensions(code)
- fn detectAntiPatterns(code)
- fn prioritizeFindings(findings)
- fn formatFeedback(findings)
+ State {
+ target = $ARGUMENTS
+ code: string
+ dimensions = [Correctness, Design, Readability, Security, Performance, Testability]
+ findings: ReviewFinding[]
+ strengths: string[]
+ checklistScope: Quick | Standard | Deep
+ }
## Constraints
- Constraints {
- require {
- Evaluate all six review dimensions for every review.
- Every finding must include observation, impact, and actionable suggestion.
- Always highlight strengths — what the code does well.
- Use constructive tone: "Consider..." not "You should...".
- Scale checklist depth to change size (quick/standard/deep).
- }
- never {
- Provide feedback without explaining why it matters.
- Focus on style over substance — use linters for formatting.
- Overwhelm with comments — prioritize and limit to top issues.
- Approve without at least one observation (positive or constructive).
- }
- }

- ## State
+ **Always:**
+ - Evaluate all six review dimensions for every review.
+ - Every finding must include observation, impact, and actionable suggestion.
+ - Highlight strengths — what the code does well.
+ - Use constructive tone: "Consider..." not "You should...".
+ - Scale checklist depth to change size (quick/standard/deep).
- State {
- target = $ARGUMENTS
- code = "" // populated by gatherContext
- dimensions = [ // six standard review dimensions
- Correctness, Design, Readability,
- Security, Performance, Testability
- ]
- findings: [ReviewFinding] // populated by assessDimensions + detectAntiPatterns
- strengths: [String] // populated by assessDimensions
- checklistScope: Quick | Standard | Deep // determined by code size
- }
+ **Never:**
+ - Provide feedback without explaining why it matters.
+ - Focus on style over substance — use linters for formatting.
+ - Overwhelm with comments — prioritize and limit to top issues.
+ - Approve without at least one observation (positive or constructive).
## Reference Materials
See `reference/` directory for detailed methodology:
- [Anti-Patterns](reference/anti-patterns.md) — Method, class, and architecture-level anti-pattern catalog
- [Feedback Patterns](reference/feedback-patterns.md) — Constructive feedback formula, tone guide, examples
- [Checklists](reference/checklists.md) — Scope-based review checklists, review metrics, process anti-patterns
## Workflow
- fn gatherContext(target) {
- Read target code and understand the change context (ticket, requirements).
- Determine change size and set checklistScope:
+ ### 1. Gather Context
- match (lineCount) {
- < 100 => Quick
- 100..500 => Standard
- > 500 => Deep
- }
+ Read target code and understand the change context (ticket, requirements). Determine change size and set checklistScope:
+
+ match (lineCount) {
+ < 100 => Quick
+ 100..500 => Standard
+ > 500 => Deep
}
- fn assessDimensions(code) {
- Evaluate each dimension systematically:
+ ### 2. Assess Dimensions
- Correctness — Does it work? Edge cases, error handling, null safety, data validation
- Design — Well-structured? SRP, coupling, cohesion, abstraction, extensibility
- Readability — Understandable? Naming, comments (why not what), complexity (<10 cyclomatic), flow
- Security — Secure? Input validation, auth checks, data exposure, dependency vulnerabilities
- Performance — Efficient? Algorithm complexity, memory, I/O optimization, caching, concurrency
- Testability — Testable? Coverage, behavior-not-implementation tests, mockable deps, determinism
+ Evaluate each dimension systematically:
- Record strengths alongside findings.

- fn detectAntiPatterns(code) {
- Load reference/anti-patterns.md for detailed catalog.
- Scan for method-level, class-level, and architecture-level anti-patterns.
- Each detected anti-pattern becomes a ReviewFinding with specific remediation.
- }
+ Record strengths alongside findings.
- fn prioritizeFindings(findings) {
- match (priority) {
- CRITICAL => Security vulnerabilities, data loss risks, breaking API changes, production stability
- HIGH => Logic errors, performance in hot paths, missing error handling, architectural violations
- MEDIUM => Duplication, missing tests, unclear naming, complex conditionals
- LOW => Style inconsistencies, minor optimizations, documentation, refactoring suggestions
- }
+ ### 3. Detect Anti-Patterns
- findings |> sort(by: [priority desc, dimension])
- }
+ Read reference/anti-patterns.md for the detailed catalog.
+ Scan for method-level, class-level, and architecture-level anti-patterns.
+ Each detected anti-pattern becomes a ReviewFinding with specific remediation.
- fn formatFeedback(findings) {
- Load reference/feedback-patterns.md for tone guidance.
+ ### 4. Prioritize Findings
- For each finding, apply the feedback formula:
- [Observation] + [Why it matters] + [Suggestion] + [Example if helpful]
+ Classify each finding by priority:
- Structure output:
- 1. Summary — overall impression, change scope
- 2. Strengths — what's done well (always include)
- 3. Findings table — sorted by priority
- 4. Detailed findings — each with observation, impact, suggestion
- 5. Checklist results — from reference/checklists.md appropriate to scope

- codeQualityReview(target) {
