quality-gate
Unified code review, maintainability validation, and architectural impact analysis. Blocks git operations until quality criteria are met.
Quality Gate
Unified quality validation that combines code review, maintainability assessment, and architectural impact analysis into a single checkpoint before commits.
When to Invoke
- After implementation, before committing
- For any non-trivial code change
Analysis Process
1. Code Quality
- Standards compliance (linting, formatting, conventions)
- Security patterns (input validation, auth, data protection)
- Best practices (error handling, logging, testing)
- Anti-patterns (code smells, tech debt)
2. Maintainability
- Naming clarity and code structure
- Complexity: cyclomatic <10/function, nesting <4 levels, functions <50 lines
- Technical debt (TODOs with context, justified shortcuts)
3. Architectural Impact
- Consistency with existing codebase patterns
- SOLID principles, DRY, separation of concerns
- KISS compliance - flag over-engineering
- Appropriate abstraction levels (not over/under-abstracted)
4. Ripple Effects
- New coupling introduced? Necessary?
- Breaking changes to API contracts, schemas, configs?
- Migration scripts provided for breaking changes?
Decision Criteria
PASS (score >= 75): Proceed to commit.
CONDITIONAL PASS (score 60-74): Proceed with noted improvements for next iteration.
FAIL (score < 60): Rework required. Provide specific, actionable feedback.
Auto-Fail Triggers
- Critical security vulnerability (plain text passwords, SQL injection, no auth)
- Breaking change without migration plan
- Data loss risk

Summary: [1-2 sentences]
[If issues exist:]
Issues:
1. [CATEGORY]: [description] -> [specific fix]
[If recommendations exist:]
Recommendations:
- [improvement for next iteration]
Boundaries
- Analysis only - does not fix code
- Escalate deep security concerns to security-auditor
- Flag obvious O(n^2) patterns but leave deep perf analysis to specialists
