deep-research

What it does

Searches, reads, extracts what it learned and what it still needs to know, then loops — refining its own direction until the configured depth runs out and it writes a Markdown report. The point is legibility: the repository is deliberately small enough to read end to end, which makes it a better starting template than a finished product. Depth multiplies both search and model calls, so cost climbs quickly. MIT.
