Key Features

• Lock spec artifacts after finalization to prevent accidental modifications
• Block destructive SDD commands (specify, clarify, plan, tasks, checklist, analyze) when locked
• Allow controlled paths (refine., bugfix.) during locked phase
• Per-spec lifecycle state stored in specs/NNN-feature/.lifecycle.json
• Mandatory before_* hooks for core SDD commands
• Cross-plugin interface: unlock --spec-dir for external plugins
• Auto-sync lock status to AGENTS.md via write-agents command
• Configurable blocked/allowed commands via lifecycle-config.yml
