Implement Plan

Execute an implementation plan file.

Task Tracking

At the start, use TaskCreate to create a task for each step:

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 /turbo:plan 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 AskUserQuestion 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
• Waiting on a gate — the plan's Context states a gate that must pass before its work can start

When you check whether a gate has passed, check each condition it names at its source of record, such as the remote's tags for another repository's release, rather than a local copy.

When a signal fires, output it as text. Then use AskUserQuestion to offer:

• Implement anyway — the marker is stale, or the gate has passed
• Pick another plan — resolve to a different file under .turbo/plans/, then confirm that plan against these same signals
• Leave it unimplemented — the plan needs revising first, or its gate has not passed
