+2. **Create Master Skill:** Create `.gemini/skills/<skill-name>/SKILL.md` as the high-level entry point. It **MUST** include a mandatory YAML frontmatter (enclosed in `---`) with `name` (unique identifier) and `description` (concise summary for autonomous activation). The body must summarize the library, link to all specific `reference-*.md` files, and highlight key "gotchas" discovered across all sessions.
 3. **Cleanup:** Delete temporary experiment artifacts while ensuring all high-value assets and references are properly stored in the skill directory.
 
 Do not stop until the master skill is fully codified and the workspace is clean.
