What problem does it solve? Architect planning sessions often end without formally closing P-## tasks, leaving TASKS.md stale and the Engineer without a clear signal to start implementation. This Skill enforces a disciplined closure workflow so no architect task is left open without a blueprint, corresponding E-## tasks, and a logged handoff. ## Core Features & Use Cases - Completion Gate Enforcement: Verifies blueprints exist in .ai/blueprints/, E-## tasks are written, and decisions are recorded before marking any P-## task DONE. - Task Status Synchronization: Updates task status through the task-synchronizer-mcp server and appends a dated entry to .ai/LOG.md. - Mandatory Engineer Handoff: Triggers the ai-handoff skill, which writes .ai/COMM.md and emits the handoff_control bridge signal so the Engineer's tmux pane wakes automatically. - Use Case: After finishing a blueprint for a new API module, invoke this Skill to close P-03, log the design summary, and automatically notify the Engineer that E-## implementation tasks are unblocked. ## Quick Start Close the completed architect task P-03, log the blueprint summary, and hand off control to the Engineer.
