/speckit.implement

Agent skill wrapper for the Claude command /speckit.implement.

When the original command text references {{INPUT}}, $1, or named arguments, map them from the user's current request.

Command Instructions

Execute the implementation plan for a feature by working through tasks.md phase by phase, using TDD where applicable.

Steps

1. Locate artifacts:

   • If input names a feature, directory, or phase number, parse it.
   • Load required: tasks.md, plan.md. Load optional: data-model.md, contracts/, research.md.
   • Load .specify/memory/constitution.md.
   • Set FEATURE_DIR to the feature directory.

2. Check checklists: Scan FEATURE_DIR/checklists/ for any uncompleted items (- [ ]). If found, report them and ask: "There are incomplete checklist items. Proceed anyway?" Stop if the user declines.

3. Determine starting phase:

   • If a phase number was provided in input, start there.
   • Otherwise start from Phase 1.
   • Skip phases where all tasks are already marked [x].

4. Execute each phase:

   • Announce the phase name and task count before starting.
   • For tasks marked [P] (parallelizable): execute them concurrently.
   • For tasks without [P]: execute in listed order.
   • For each task:
     • Write tests first (TDD), then implement the minimum code to satisfy the task.
     • Mark the task [x] in tasks.md immediately after completion.
     • Run available test and lint commands to verify no regressions.
   • If a non-parallelizable task fails, stop and report. Do not proceed to the next task until resolved.

5. Validate completion after all phases:

   • All tasks in tasks.md are marked [x].
   • All functional requirements from spec.md are addressed.
   • Tests pass and no new lint errors.

6. Report: Tasks completed, any skipped tasks with reasons, test results summary.

Next step: Run /speckit.taskstoissues to track remaining work as GitHub issues, or commit and open a PR.
