 For `/autoplan` driven from Capy, read `autoplan/DRIVER.md` in the checkout (`~/.local/share/gstack/autoplan/DRIVER.md`): the compact phase loop, artifact contract and gate protocol, without the interactive preamble. A checkout without that file predates it; follow its `autoplan/SKILL.md` instead. Run every command with the `GSTACK_LAUNCH` assignments and read outputs as files, not prose: the run directory holds `run.json`, `decisions.jsonl`, `findings.jsonl`, `tasks.jsonl`, `timing.json`, `plan.md` and `review-record.md`, and the run ends with `GSTACK_RESULT: skill=autoplan status=gate_pending run=<dir>`. `~/.local/share/gstack/bin/gstack-artifact validate <dir>/run.json` is the completion check. The gate is answered through `gstack-autoplan answer` (or `gstack-gate parse`) with the printed `gate_rev`; an unattended run never approves its own gate. `docs/unattended.md` in the checkout is the contract.
 
+For `/ship` driven from Capy, read `ship/DRIVER.md` in the checkout (`~/.local/share/gstack/ship/DRIVER.md`): the phase loop at one or two calls per phase, and the section each STOP needs. A checkout without that file predates it; follow its `ship/SKILL.md` instead. It starts the budget with `--delegate measured`.

 Run directories and scratch on Capy live under `~/.capy/work/<name>` (`--out ~/.capy/work/<project>/autoplan`), never `/tmp`: Capy wipes `/tmp` when a machine sleeps, and a vanished run cannot be resumed, answered or exported. The same holds for any file a later turn reads.
 
 Capy checklist for `/autoplan`: drive `gstack-autoplan`, never a hand adaptation presented as a run. Relay `gstack-gate render <dir>/gate.json --all` with `rec` (every recommendation, plan changes included) as the one-word default; answer with `--by agent:<id> --owner-reply "<their words>"`. Set `GSTACK_AUTOPLAN_CHECKPOINT_DIR` to a private project-user Drive folder; after machine replacement, `gstack-autoplan resume --out <new dir> --from <that dir>` restores the newest valid checkpoint.
