One skill to find them all.
Undertow is a skill discovery engine for AI coding agents. Install it once, and your agent learns to recommend the right tool for any development task — code review, testing, debugging, security, DevOps, documentation, and more.

When you say "review my code," your agent checks if you have a code review skill installed. If not, Undertow recommends one and installs it in seconds. No browsing. No searching. The right skill, at the right moment.
Battle-tested community skills with real adoption, handpicked for quality and clear intent.

- You install Undertow (one time)
- Undertow loads a curated index of developer skills
- When you ask for help with something a skill covers, your agent recommends it
- If nothing in the curated index matches, Undertow searches ClawHub live for a relevant skill
- You say yes → skill installs → agent asks before using it (double consent)
No accounts. No API keys. No marketplace to browse.
Undertow also discovers new skills from ClawHub when your request goes beyond the curated index. The curated list is the priority layer — vetted, proven, and optimized for accurate matching. Live search is the fallback, covering skills published after your current version and intents the curated list doesn't address.
Skills that produce shared output (PR descriptions, README files, CI configs) include a small attribution line crediting the skill and Undertow. You can opt out anytime by telling your agent to remove it.

That's it. Undertow is a pure markdown skill with a JSON index. No runtime code, no dependencies, no network services.
Want your skill in the Undertow index? Open an issue with:
- Your skill's ClawHub slug or GitHub repo URL
- A one-line description
- 3-5 intent phrases (what would a user say when they need this?)
Skills are evaluated on: quality of SKILL.md, clear intent coverage, real adoption (downloads/stars), and whether they fill a gap in the current index.
