implement

To execute specific phases from PLAN.md and write code into spaces, use the implement skill to trigger phase steps, generate code, and record progress. It reads issue context from ideas/ to ensure changes align with the project plan.

Automating phase advancement during code implementation is handled by the --next command, which auto-finds and executes the next uncompleted phase from PLAN.md. The --full command executes all remaining phases.

Progress tracking works by updating a worklog and ideas/ directory after executing a phase from PLAN.md. The skill writes code into spaces/ and records progress to ensure changes are traced against the plan.

Yes, you need a PLAN.md file to automate code writing and phase execution because it serves as the source of phases. The skill also reads issue context from ideas/ to align changes.

You can run all remaining implementation phases automatically by passing the --full flag. This executes every uncompleted phase from PLAN.md sequentially, writes code into spaces/, and updates the worklog.
