# 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.

Workflow state lives at `.turbo/workflows/<slug>.md` — slug from the resolved plan's basename. It pairs one-to-one with the thread's goal. When this run's `create_goal` attempt succeeds, write the file fresh: `Status: active` plus this invocation's `update_plan` list as a checkbox list. When an unfinished goal already exists, mirror into the workflow file its objective names; when it names none, continue without workflow state. Mirror every `update_plan` call into the file; it holds the pipeline's remaining steps and their statuses. When this run created the goal, run the terminal step in order: mark the final entry completed and mirror it, set `Status: closed`, mark the goal complete with `update_goal`, then emit any halt message.

Attempt `create_goal` with the objective: "Execute the implementation plan at <plan path> through `$implement`, then set the plan's frontmatter status to done when it has frontmatter. Workflow state: `.turbo/workflows/<slug>.md`; mirror every `update_plan` call into it. Loop state lives under `.turbo/loops/`. After any context compaction, re-read the plan file, the workflow file, and any active ledger, and continue from the first unfinished entry. Mark this goal complete only after that status update, or after `$implement` completes for a plan without frontmatter." If an unfinished goal already exists, an outer workflow owns it; continue without creating one.

## Step 2: Read Context Files

Read in full:

- Every file listed in the plan's **Context Files** section
- Files the user referenced in their original request (if any)
- Every file path the plan references in the Context, Pattern Survey, and Implementation Steps sections

## Step 3: Run `$implement` Skill

Run the `$implement` skill. The plan file, its file references, and its Verification section are already in conversation context from Step 1.

## Step 4: Update Plan Status

After `$implement` completes, set the plan's frontmatter `status:` to `done`. If the plan is the legacy `.turbo/plan.md` without frontmatter, skip the status update.

If this run created a goal in Step 1, mark it complete with `update_goal`.

Then call `update_plan` to mark this step completed and continue with the next step of the active workflow.

## Rules

- The plan file is read-only during execution. If revisions are needed, run `$refine-plan` or `$draft-plan` separately.
- Never skip Step 2.
- Never enumerate or execute the plan's Implementation Steps inline. The work runs through `$implement`. Restating steps as a turn-level narration counts as inline execution and bypasses the delegation.
- If the plan's Implementation Steps or Verification include `git commit`, `git push`, or PR creation, halt before Step 3 and ask the user to remove them via `$refine-plan`.
