Implement Plan

Implement Plan

Execute an implementation plan file.

Task Tracking

At the start, use update_plan to track each step, restating any remaining steps of a parent workflow alongside them:

1. Resolve and read the plan file
2. Read context files
3. Run $implement skill
4. Update plan status

Step 1: Resolve and Read the Plan File

Determine which plan file to implement using these rules in order:

1. Explicit path — If an absolute or relative path was passed and that file exists, use it
2. Explicit slug — If a slug was passed (e.g., add-image-cache), resolve to .turbo/plans/<slug>.md if that file exists
3. Single file — Glob .turbo/plans/*.md. If exactly one plan exists, use it
4. Most recent — If multiple plans exist, use the most recently modified
5. Legacy fallback — If .turbo/plans/ does not exist but .turbo/plan.md exists, use it
6. Nothing found — If no rule above resolved to an existing file, tell the user to run $turboplan and stop. When a slug or path was passed but no file matched it, say which one was tried

If multiple plans exist and the most-recent choice is non-obvious (e.g., several plans were modified within the same minute), use request_user_input to let the user pick from the candidates.

State the resolved plan path before continuing, then read the file.

Unless an explicit path or slug was passed, confirm the resolved plan still describes work that remains to be done:

• Already implemented — the frontmatter status: is done

When the signal fires, output it as text. Then use request_user_input to offer:

• Implement anyway — the marker is stale
• Pick another plan — resolve to a different file under .turbo/plans/, then confirm that plan against this same signal
• Leave it unimplemented — the plan needs revising first

On Leave it unimplemented, tell the user to bring the plan current with $refine-plan and run this skill again. Call update_plan to drop the remaining implement steps, restating any remaining steps of a parent workflow, then continue with the next step of the active workflow.
