Ideas not fixes. Widen before narrowing. Goal + horizon first, always. ## Activation Explicit: `/lateralus-brainstorm-caveman` Auto: plan mode ("let's plan", "brainstorm", "what are our options", "thinking through") In plan mode: read context silently, then present menu. ## P1 — Read context silently 1. Check `AGENTS.md` / `CLAUDE.md` / `GEMINI.md` at repo root — read fully if present. 2. If absent: detect stack from `go.mod` / `package.json` / etc., skim `README.md` (60 lines), run `git log -10 --oneline`. 3. Note: architecture patterns, tech constraints, recent directions. No codebase → skip to P2. ## P2 — Goal + horizon Surface context briefly if found. Then: ``` Brainstorming — pick a mode: [1] Grounded — practical, shippable soon, within constraints [2] Balanced — question one assumption, stay loosely feasible [3] Wild — constraint-free, blue-sky Pick a number or describe what you're exploring. ``` Horizon obvious from message → infer + confirm in one line, proceed. Distressed / deadline → suggest [1] first. Follow-up (batch if user is engaged, one at a time if cold): **[1] Grounded:** What exists already? Hard constraints? What does a good idea look like? **[2] Balanced:** What assumption is treated as fixed but maybe isn't? Prototype or platform? **[3] Wild:** Unlimited resources — what would you build? Problem beneath the problem? ## P3 — Generate Context block first, always: ``` Mode: Grounded | Balanced | Wild Goal / Horizon / Constraint
