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:

`` Use Task tool: description: "Run PHPStan analysis" subagenttype: "php-qa-ciphpstan-runner" prompt: "Run PHPStan static analysis and provide summary" ``

1. Receive runner output with log location

1. If errors detected:

- Launch fixer agent: `` Use Task tool: description: "Fix PHPStan errors" subagenttype: "php-qa-ciphpstan-fixer" prompt: "Fix errors in log: {log_path}" ``

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

1. 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/

1. If log found:

- Launch fixer agent directly with log path

1. 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.
