PHPStan Runner Skill

This skill provides intelligent PHPStan static analysis and fixing through specialized agent delegation.

Agent Delegation Strategy

This skill delegates to specialized agents via the Task tool:

1. php-qa-ci_phpstan-runner agent (haiku model) - Runs analysis and parses results
2. php-qa-ci_phpstan-fixer agent (sonnet model) - Analyzes and fixes errors
3. Escalation - Uses opus model or asks human for stubborn issues

Workflow

When User Says: "Run PHPStan"

1. Launch runner agent:

   Copy

   Use Task tool:
     description: "Run PHPStan analysis"
     subagent_type: "php-qa-ci_phpstan-runner"
     prompt: "Run PHPStan static analysis and provide summary"
   

2. Receive runner output with log location

3. If errors detected:

   • Launch fixer agent:
     Copy

     Use Task tool:
       description: "Fix PHPStan errors"
       subagent_type: "php-qa-ci_phpstan-fixer"
       prompt: "Fix errors in log: {log_path}"
     

4. After fixes applied, re-run via runner agent

5. Repeat cycle until:

   • Analysis passes → Success
   • Same errors persist 2+ times → Escalate to opus or human
   • User intervention needed → Ask user

When User Says: "Fix the PHPStan errors"

1. Check if recent log exists in var/qa/phpstan_logs/

2. If log found:

   • Launch fixer agent directly with log path

3. If no log:

   • Launch runner agent first to generate log
   • Then launch fixer agent

Escalation Triggers

Launch opus model or ask human when:

• Fixer agent reports "cannot fix" for same error 2+ times
• Architecture questions arise (design patterns, type hierarchies)
• User explicitly requests explanation of errors

Runner Agent Reference

The phpstan-runner agent (haiku model) handles:

• PHPStan execution with proper configuration
• Log parsing for error patterns
• Concise summary generation

See .claude/agents/php-qa-ci_phpstan-runner.md for agent implementation details.

Fixer Agent Reference

The phpstan-fixer agent (sonnet model) handles:

• Log file discovery and parsing
• Error grouping by pattern
• Fix implementation for common PHPStan issues
• Verification that fixes resolve issues

See .claude/agents/php-qa-ci_phpstan-fixer.md for agent implementation details.
