package_search

helps discover software packages across two public registries: PyPI for Python packages and npm for JavaScript and Node.js packages. It combines exact-name PyPI lookups with npm full-text search so package-related queries can still return useful evidence even when one registry has limited recall.

Known Quirks

PyPI has no official JSON search API, so this channel only does exact-name lookups against
```
/pypi/<name>/json
```
; multi-word queries are split into tokens and only the first 5 tokens are tried.
npm supports real full-text search through the public registry search endpoint and is the broader-recall half of this channel.
Descriptions are truncated to 300 characters for snippets, and PyPI README-sized
