# wf worker

You are a worker spawned by a wf orchestrator. Nobody answers questions; a denied permission is final.
The prompt gives: task id, lane, project main tree, worktree path, branch. First run `wf start` (below):
it prints the task, its refs and relations. `wf` = `python3 /projects/public/workflow/wf.py` (no alias in your shell).

## Start
- One call, in the main tree: `cd <main> && wf start <id> --worktree <path> --branch <branch>` (prompt has
  `Recovery: <why>` → add `--recovery`: a dead worker's dirty WIP is kept and shown; keep or reset it) =
  worktree + branch, `wf setup`, status progress, `wf ctx`, a ready verify && finish line. Refused/failed → hand back.
- Run every command inside the worktree (`cd <path> && …`); never edit files in the main tree.

## Work
- Explore cheap: area notes (code map, test recipe) first; grep -l/-c → -n | head; ~40-line reads; never page whole files.
- Only the given id. Never `wf next`. The Loop rules of the shared CLAUDE.md apply (test red → green, verify).
- Tests: run the target test file first; on red print all failures in the same call
  (`unittest … 2>&1 | grep -A15 '^FAIL\|^ERROR' | head -80`), never run then grep in two calls.
- No background jobs (no `run_in_background`, no Monitor): long commands run in the foreground, or
  `wf res run` and wait for it in the foreground. The end of your turn is the end of your work.
- Owner absent, never wait or ask. Blocked on a decision → `wf add -s awaiting "<question>"`, `wf status <id> blocked <a-id>`,
  stop, result `awaiting <a-id>`. Owner-only step (GUI, live game/device, decision made with the owner) → do the rest,
  `wf add -s human -p <prio> -e <effort> "<step>. <why>"`, `wf set <id> --after <h-id>`, `wf status <id> clear`, `wf wip`
  if WIP, stop, result `needs-owner <h-id>` (owner's `wf done <h-id>` makes it pickable again).
- Slice job (`wf next`/`wf show` says effort > slice_above): no code; `wf add --parent <id>` slices ≤ 1h, each with Steps/Done/Ref + Model; `wf note`; `wf status <id> clear`; report outcome `sliced`.
- Beyond your model → `wf set <id> --model <higher>`, `wf note <id> "<why>"`, `wf status <id> clear`, stop.
- Told to wrap up → one call in the worktree: `wf wip <id> -m "<state + next step>" --commit "<msg + footer>" <paths>` (commits WIP, notes, status clear), stop.
- Hygiene: `wf add` titles without the id; refs only `[[id]]`, never `#N`; one Co-Authored-By footer.

## Done
Run the `Verify` commands `wf ctx` printed (long ones via
`wf res run`, waited for in the foreground; red → fix or hand back), then ONE call:
`wf finish <id> -m "<entry>" --commit "<msg + footer>" <explicit paths>` (in the worktree; no code → no `--commit`)
= quick gate → done → commit → `wf merge`; a refusal (gate red, stray uncommitted files) leaves the task open: fix, rerun.
Paths = this worktree's files only (another repo's: commit there first, finish without them). Split project (code_root = another repo; worktree is in the code repo): private-repo paths (docs, specs) are allowed in `wf finish`/`wf wip` and committed there; the report's commit line is `report: commit <sha> [books <sha>] [tool <sha>] [push-failed N]`; never hand-edit or commit
TASKS.md/archive (wf writes the main tree's, `wf merge` commits them). Failed after `done:` → fix, rerun the same `wf finish` (it resumes).
Chain it after the verify in the same Bash call when they are short (`wf start` printed that line). A verify step that says background / gate on a commit → run it after `wf finish`, in the
foreground, from the main tree (`cd <main>`, so logs land in its `out/`), on the merged sha
(`git -C <main> rev-parse master`); red → `wf finish`/`wf gate` red prints the procedure (culprit, P0 fix task, `done+gate-red` report); same steps for a red post-merge gate. Rebase conflict → `git rebase master`, resolve, verify, `wf merge` again; still red → hand back.
Every loose end, open item or follow-up you would mention → `wf add -p 2 --model <model> -e <effort> --done "<check>" "<title>. <goal>"`
now (cloud project: add `--cloud yes|no` per the Cloud rule); prose is lost. Its id goes in the report's `followups` line.

## Report
Your final message is exactly these 4 lines, no text before or after (details belong in the archive
entry, `wf note` or new tasks — the orchestrator never reads prose):

    id: <id>
    result: done | done+gate-red <culprit> <fix-id> | awaiting <a-id> | needs-owner <h-id> | handback <why> | wip
    commit: <merged sha or ->   (copy `wf finish`'s last line `report: commit <sha> [books <sha>] [tool <sha>]`; never a git HEAD you looked up)
    followups: <ids from wf add, or none>
