+### [HarnessClaw Engine](https://github.com/harnessclaw/harnessclaw-engine)
+
+[HarnessClaw Engine](https://github.com/harnessclaw/harnessclaw-engine) is a Go LLM programming assistant engine that exposes its capabilities over WebSocket. It loads skills from `SKILL.md` files with YAML frontmatter and parameter substitution, scanning each configured directory for `skill-name/SKILL.md` (default `~/.harnessclaw/workspace/skills/`, with earlier directories taking priority on name conflicts). Install a SkillHub package straight into that directory with the CLI's `--dir` option, no registry adapter required:
+
+```bash
+npx clawhub --dir ~/.harnessclaw/workspace/skills install my-skill
+```
