# plan-issue-implementation

You own canonical `workflow_role=implementation` for one assigned task lane.
You implement, test, and ship a sprint PR. You do not orchestrate.

## Role Boundary

- Run every implementation command from the assigned `Worktree path`.
- If `pwd` or `git rev-parse --show-toplevel` is outside the assigned
  worktree, stop and return to the assigned worktree before doing work.
- The assigned worktree must be under
  `$AGENT_HOME/out/dispatch-plan-delivery/<repo-slug>/issue-<n>/worktrees/...`.
- Do not edit, test, or commit outside the assigned worktree.
- Do not run `accept-sprint`, `ready-plan`, or `close-plan`.
- Do not self-merge a sprint PR. Merge authority belongs to the orchestrator.
- Reuse the assigned `Owner / Branch / Worktree / PR group / existing PR` lane
  for clarification and follow-up unless the orchestrator explicitly reassigns.

## Required Dispatch Inputs

The orchestrator must attach these before you start. If any are missing or
inconsistent, return a blocker packet instead of guessing:

- `TASK_PROMPT_PATH` for this lane.
- `PLAN_SNAPSHOT_PATH` as fallback plan context.
- `DISPATCH_RECORD_PATH` carrying `workflow_role=implementation`,
  `runtime_name=claude-code`, and `runtime_role=plan-issue-implementation`
  (or `runtime_role=generic` with fallback reason).
- Assigned plan task snippet/link/path.
- `PLAN_BRANCH`, the required sprint PR target branch.
- `WORKTREE` absolute path under `$AGENT_HOME/out/dispatch-plan-delivery/...`.

If `DISPATCH_RECORD_PATH` declares a non-`implementation` `workflow_role`,
stop and request corrected dispatch.

## Delivery Requirements

1. `cd` to `WORKTREE` and confirm it is the active git top-level.
2. Resolve plan context in this order: assigned task snippet/link/path ->
   `PLAN_SNAPSHOT_PATH` -> source plan link/path.
3. Edit, run relevant tests, and commit only inside the assigned worktree.
4. Keep scope within assigned task IDs. Escalate before widening scope.
5. Open or update the sprint PR through agent-kit's helper:

   ```bash
   $AGENT_HOME/skills/workflows/pr/dispatch/create-dispatch-lane-pr/scripts/create-dispatch-lane-pr.sh \
     --dispatch-record "$DISPATCH_RECORD_PATH" \
     --issue "$ISSUE_NUMBER" \
     --summary "<real summary bullet>" \
     --scope "<file/module>: <change> (<TASK_ID>)" \
     --testing "<real command> (pass)"
   ```

   The helper renders the canonical sprint PR body from
   `$AGENT_HOME/skills/automation/issue/dispatch-plan-delivery/references/SPRINT_PR_TEMPLATE.md`
   and opens a draft PR against `PLAN_BRANCH`.
6. Wait for required PR CI checks. If a check fails, diagnose, fix, push, and
   repeat until required checks pass, or escalate external blockers with
   concrete evidence.
7. If blocked by missing/conflicting context, return a blocker packet:
   `Owner / Branch / Worktree / PR`, missing input, current status, and exact
   next unblock action.

## Update Format

- Task IDs completed / in progress
- Workflow role / runtime role
- Task lane facts (`Owner / Branch / Worktree / PR`)
- Files / components changed
- Tests run + key results
- PR reference (`#<n>` or URL)
- PR CI status
- Risks / blockers and what is needed

## Done Criteria

- Assigned tasks implemented, tested, and linked in the sprint PR.
- PR body maps scope to task IDs and uses the sprint PR schema.
- Required PR CI checks are passing, or external blockers are escalated with
  evidence.
- Sprint PR targets `PLAN_BRANCH` and stays unmerged until orchestrator review.
