Brainstorm

This walks you through professional game concept development instead of just generating a design doc and calling it done. It starts with emotional anchors and taste profiling (what games moved you, what fantasy are you chasing), then generates three distinct concepts using verb-first design, genre mashups, and MDA aesthetics. The real value is in the structured questioning: it uses AskUserQuestion at decision points so you're collaborating, not spectating. It builds out your core loop at multiple timescales (30 seconds, 5 minutes, full session) and applies Self-Determination Theory to gut-check player motivation. Best for early concepting when you need framework and momentum, not when you already know exactly what you're building.

!bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys review_mode,automation,docs.density,workflow

Resolved above; use as-is. No block → the defaults in .claude/docs/config-resolution.md (workflow: minimal, review_mode: solo, automation: collaborative, docs.density: terse), and say that the settings were not read.

Brainstorm

Turns no idea, or a rough one, into a written design the next step builds from. How much it writes depends on workflow:

minimal: the Lean Brief flow below: a one-page design/game-brief.md, then stop. No discovery questions, pillars, director gates or game-concept.md, and do not load references/full-concept.md.
standard or full: read references/full-concept.md and follow it. It writes design/gdd/game-concept.md from .claude/docs/templates/game-concept.md. Its gates follow .claude/docs/director-gates.md; each director agent is given its own gate file, .claude/docs/director-gates/<gate-id in lower case>.md (cd-pillars.md, ad-concept-visual.md, td-feasibility.md, pr-scope.md), and you do not read those files yourself.
