Workflow State Patterns

Multi-phase workflows need phase enforcement, session continuity, and quality gates. This pattern uses file-based state + hooks.

Quick Start

1. Define phases: analyze → plan → execute → verify
2. Create state files on phase completion: .workflow-phase-done
3. Add PreToolUse hooks to check required state files
4. Add PostToolUse hooks to create state files

Core Concept

Phase 1 → [POST HOOK] → .analysis-done
Phase 2 → [POST HOOK] → .plan-approved
Phase 3 → [PRE HOOK checks] → [POST HOOK] → .execution-done
Phase 4 → PASS: cleanup all / FAIL: preserve for retry
