Run `.specify/scripts/bash/check-prerequisites.sh --json --paths-only` from repo root **once** (combined `--json --paths-only` mode / `-Json -PathsOnly`). Parse minimal JSON payload fields: + - `FEATURE_DIR` + - `FEATURE_SPEC` + - (Optionally capture `IMPL_PLAN`, `TASKS` for future chained flows.) + - If JSON parsing fails, abort and instruct user to re-run `$speckit-specify` or verify feature branch environment. + - For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot"). + +2. **IF EXISTS**: Load `.specify/memory/constitution.md` for project principles and governance constraints. + +3.

For example, `Acceptance device/runtime matrix (FR-023)` is INVALID — it is a label, not a question. + - After the `?`, the only permitted suffix is an optional parenthesized requirement/question id. Exact format: `**Question:** ?` or `**Question:** ? (FR-023)`. Never put the id before the `?`, and never use the id (alone or with a topic label) as the whole prompt. + - Immediately after the question line, add one plain-language "Why it matters" sentence (the stake for acceptance or shipping) before the recommendation/options. + - Use everyday wording; introduce jargon only if defined in the same sentence.
