Scope is a single backlog item (`[B##]` or `[F##]` or `[T##]`); project-level exploration stays with `/hv-vision`. The artifact lands at `.hv/designs/<ID>.md` and feeds `/hv-plan` as soft input — never required. ## Step 1 — Preflight ```bash .hv/bin/hv-preflight ``` See `docs/reference/preflight.md` for exit-code handling. **Autonomy gate.** Read `autonomy.level` and parse the `--auto-loop` flag: ```bash LEVEL=$(jq -r '.autonomy.level // "off"' .hv/config.json) ``` Also parse `AUTO_LOOP`: scan `$ARGUMENTS` (the skill `args` value) for the literal string `--auto-loop`; set `AUTO_LOOP=true` if present, `AUTO_LOOP=false` otherwise. Then branch: - **`LEVEL == "loop"` AND `AUTO_LOOP=false`** — print *"Note: /hv-brainstorm is skipped under loop autonomy (throughput mode). Re-run with `/hv-config` set to off or
