cursor-worker-implement

name	cursor-worker-implement
description	Runs bounded implementation via cursor-agent CLI with Composer 2.5. Use when Fable has a clear plan and bulk edits, migrations, or multi-file work should not run on Fable tokens. Requires cursor-agent on PATH and Cursor subscription.

Cursor worker — implement

Parent (Fable) orchestrates; Composer executes via cursor-agent. Do not prompt cursor-agent like Claude — use a self-contained brief (paths, scope, constraints, verification).

Prerequisite

which cursor-agent   # must exist; uses Cursor subscription auth

Workflow

1. Confirm scope with the user if ambiguous.
2. Write a self-contained prompt (repo root, files, acceptance criteria).
3. Run from repo root:

REPO="$(git rev-parse --show-toplevel)"
cursor-agent -p --force --output-format json \
  --workspace "$REPO" \
  --model composer-2.5 \
  "YOUR_SELF_CONTAINED_PROMPT"

4. Parse JSON stdout; summarize files changed, commands run, blockers.
5. If the parent needs proof, load cursor-worker-review or run project checks.

--force auto-approves edits/shell (headless has no prompt to answer); --trust alone only trusts the workspace. Add --worktree <slug> for parallel edits that must not collide. Default model composer-2.5 (not -fast unless asked).

Timeouts

Long runs may exceed the parent shell timeout. For multi-hour work: run in background, log to a file, poll for completion.

When parent should use this

• Clear-spec implementation, refactors, migrations, repetitive edits
• Parent should not bulk-edit when this skill is available
