Quality Standards Skill

Context (Input)

• Need to understand protected quality thresholds
• Running comprehensive quality checks before commit
• Determining which specialized skill to use for specific issues
• Quick reference for quality tool commands

Task (Function)

Understand quality metrics and route to appropriate specialized skill for fixes.

Success Criteria: Know which skill to use for your specific quality issue.

Protected Quality Thresholds

CRITICAL: These thresholds are protected and must NEVER be lowered.

PHPInsights (Source Code)

make phpcsfixer

PHPInsights (Tests)

make phpcsfixer

Other Tools

Quick Reference Commands

Comprehensive Checks

# Run all CI checks (recommended before commit)
make ci

Success: Must output "✅ CI checks successfully passed!"

Individual Quality Checks

make phpinsights

make phpmd

make psalm

make psalm-security

make deptrac

make phpcsfixer

make composer-validate

Testing Commands

make unit-tests

make integration-tests

make behat

make all-tests

make tests-with-coverage

make infection

Routing to Specialized Skills

When quality checks fail, use the appropriate specialized skill:

Architecture Issues

• Deptrac violations → deptrac-fixer

  • Domain depends on Infrastructure
  • Layer boundary violations
  • "must not depend on" errors

• DDD architecture patterns → implementing-ddd-architecture

  • Creating new entities/value objects
  • Implementing CQRS patterns
  • Understanding layer responsibilities

Code Quality Issues

• High cyclomatic complexity → complexity-management

  • PHPInsights complexity < 94%
  • PHPMD reports high CCN
  • Methods too complex

• Code style issues → Run

  make phpcsfixer

  • PSR-12 violations
  • Line length > 100 chars
  • Formatting issues

Testing Issues

• Test failures → testing-workflow
  • Unit/Integration/E2E failures
  • Mutation testing (Infection)
  • Test coverage < 100%

Workflow Integration

• Before committing → ci-workflow

  • Run all checks systematically
  • Fix failures in priority order
  • Ensure all checks pass

• PR review feedback → code-review

  • Fetch and address PR comments
  • Systematic comment resolution

Quality Improvement Workflow

Step 1: Run Comprehensive Checks

make ci

Step 2: Identify Failing Check

Check output for specific failure:

❌ CI checks failed:
  - phpinsights: Complexity score too low (93.5% < 94%)

Step 3: Use Specialized Skill

Based on failure type, use appropriate skill:

Step 4: Re-run CI

make ci

Repeat until: "✅ CI checks successfully passed!"

Constraints (Parameters)

NEVER

• Lower quality thresholds in config files (

  phpinsights.php

  ,

  infection.json5

  , etc.)
• Skip failing checks to "save time"
• Commit code without all CI checks passing
• Modify

  deptrac.yaml

  to allow violations (fix code, not config)
• Disable security checks

ALWAYS

• Fix code to meet standards (not config to meet code)
• Run

  make ci

  before creating commits
• Use specialized skills for specific quality issues
• Maintain 100% test coverage
• Keep cyclomatic complexity low (target: < 5 per method)
• Respect hexagonal architecture boundaries

Format (Output)

Expected CI Output

✅ CI checks successfully passed!

Expected PHPInsights Output

[CODE] 100.0 pts       ✅ Target: 100%
[COMPLEXITY] 94.0 pts  ✅ Target: 94%
[ARCHITECTURE] 100 pts ✅ Target: 100%
[STYLE] 100.0 pts      ✅ Target: 100%

Expected Deptrac Output

✅ No violations found

Expected Infection Output

Mutation Score Indicator (MSI): 100%

Verification Checklist

After using this skill:

• Identified which quality check is failing
• Selected appropriate specialized skill for the issue
• Ready to execute specialized skill workflow
• Understand which threshold applies to the failure
• Know the command to re-run the check after fixes
