brainstorm is agent-read markdown (skill) from lstr-1/skills: Use when you have a feature idea but the scope or UX is still ambiguous — runs a lightweight Socratic design dialogue (3-5 AUQ rounds) and writes a spec markdown file. Use BEFORE /plan feature when product intent needs validation; skip to /plan feature when scope is already clear. HARD-GATE prevents any code work until the design is user-approved..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Brainstorm Skill
> Lightweight Socratic design dialogue for per-feature exploration. Sibling to `/plan feature`, not a replacement. Produces `docs/specs/YYYY-MM-DD-<slug>-design.md` after the user approves an approach.
## Soul Reference
Read `soul.md` in this skill directory before anything else. It defines WHO you are — a Design Facilitator who shapes vague ideas into approved designs through Socratic questioning. Every interaction in this skill should reflect that identity.
## When to use
- A new feature is requested but the UX, product surface, or scope is still ambiguous
- The user wants design validation before committing to a full PRD
- Multiple plausible approaches exist and the trade-offs need to be surfaced first
- A "what should this look like?" question that would otherwise collapse into unfocused implementation work
## When NOT to use
- Scope is already clear → use `/plan feature` directly
- A full project kickoff is needed → use `/plan new`
- A spec or PRD already exists → use `/plan feature` to formalize it
- Pure bug fixes or regressions → use `/debug` (issue #37) once shipped
