Btca Cli

This lets Claude run btca commands to ground answers in actual source code from git repos, local directories, or npm packages. You'd reach for it when you need detailed research on a specific library or framework, like asking how Svelte implements writable stores or how React exports useTransition. It works with persistent resources you've added to your config or one-off anonymous sources inline. The real value is keeping Claude anchored to canonical source instead of general knowledge, which matters when you're debugging integration issues or learning a library's internals. Fair warning: you need btca installed and configured first, so there's setup overhead before this becomes useful.
