Individual skill
capability-discovery
Detect which MCP servers, Claude Code plugins, and CLI tools are available in the current environment, so kits and build sites can bind to real capabilities instead of imagined ones. Runs via /ck:init --tools-only or `cavekit-tools.cjs discover`. Writes .cavekit/capabilities.json. Trigger phrases: "what do we have available", "what's installed", "detect tools", "can we use X", "setup tools".

# Capability Discovery
The pipeline should never invent tools. Before drafting a kit that references
GitHub Actions, Supabase, Codex, or any other external dependency, check what
actually exists.
## What we detect
- **CLI tools on $PATH**: `gh`, `git`, `node`, `go`, `rustc`, `cargo`,
`python3`, `pip`, `docker`, `vercel`, `supabase`, `firebase`, `wrangler`,
`ffmpeg`, `playwright`, `codex`, `graphify`.
- **MCP servers**: parsed from `.mcp.json` in the project root and
`~/.claude.json` (user level).
- **Claude Code plugins**: parsed from `~/.claude/plugins/installed_plugins.json`.
