setup

# Mycelium plugin setup When this skill runs, do the following sequence. The skill is designed to be safe to re-run — every step is idempotent. ## Step 1: Detect initialization state Check whether the user's project already has Mycelium project-state. The signal that initialization has happened: ```bash test -f "$CLAUDE_PROJECT_DIR/.claude/diamonds/active.yml" ``` If the file exists, print: > "Mycelium project state is already initialized. Existing canvas, diamonds, and memory are preserved. Run `/mycelium:diamond-assess` to see current state." Then exit. Do NOT touch existing files. If the file does NOT exist, continue to Step 2. ## Step 2: Create project-state directory structure Resolve the project root: use `$CLAUDE_PROJECT_DIR` if set, else fall back to `pwd`. (Claude Code sets it automatically; non-Claude-Code agents may not.) Create these directories in the user's project (using Bash `mkdir -p`): ``` <project_root>/.claude/canvas/ <project_root>/.claude/diamonds/ <project_root>/.claude/memory/ <project_root>/.claude/harness/ <project_root>/.claude/evals/ <project_root>/.claude/jit-tooling/ ``` These directories hold project-specific state that the user's project owns and commits to git. Framework reference content (skills, hooks, theory gates) lives in the plugin cache and is not duplicated here. A `.claude/state/` directory may also be present — that one is created and owned by Claude Code itself for runtime state (audit logs, etc.), not by Mycelium. Myc...
