+- **Registry Update**: Now tracking 883 skills.
 - **CLI Installer**: Fixed the default `.agent/skills` path to properly default to `~/.gemini/antigravity/skills` and added an explicit `--antigravity` flag (fixes #101).
 - **Validation**: Enforced strict folder-to-name matching and concise (<200 char) descriptions based on `agentskills-ref` (fixes #97).
 - **Validation**: Added build-time Markdown dangling link validation to `validate_skills.py` to prevent agents from hallucinating relative paths (fixes #102).
