# /speckit.implement — execute the task list Gate: tasks.md exists for the current feature (run `python3 speckit.py status` to confirm); if it is missing, stop and run /speckit.tasks first. 1. Read spec.md, plan.md and tasks.md of the current feature. 2. Work through tasks.md strictly top to bottom, phase by phase: implement each task test-first, and flip its checkbox to `- [x]` only after its verification actually passed. 3. Never renumber or delete tasks; append newly discovered work as new checkboxes at the end of the fitting phase. 4. When all boxes are checked, run `python3 speckit.py check` and report the result to the user together with how to run the built feature.
