# Brainstorm Guide the user through a structured design conversation that produces a written, approved design document before any implementation begins. The output is a persistent file in the project that feeds into Claude Code plan mode and then into `/optimus:tdd` for test-first implementation. ### The Hard Gate **No implementation until the design is approved.** Do not invoke any implementation skill, write any production code, scaffold any project structure, or take any implementation action until you have written a design doc and the user has approved it. This applies to all tasks — even seemingly simple ones. Unexamined assumptions in "simple" projects cause the most wasted effort. ## Step 1: Pre-flight Read `$CLAUDE_PLUGIN_ROOT/skills/init/references/multi-repo-detection.md` for workspace detection. If a multi-repo workspace is detected, process within the repo the user is targeting. If ambiguous, ask which repo. ### Verify prerequisites Check that `.claude/CLAUDE.md` exists. If it doesn't, stop and recommend running `/optimus:init` first — project context and coding guidelines shape design decisions. Load these documents: | Document | Role | |----------|------| | `.claude/CLAUDE.md` | Project overview, tech stack, architecture | | `coding-guidelines.md` | Quality standards that constrain the design | **Monorepo path note:** Read the "Monorepo Scoping Rule" section of `$CLAUDE_PLUGIN_ROOT/skills/init/references/constraint-doc-loading.md` for doc layout and sc
