- [KeygraphHQ/shannon](https://seerepo.com/r/KeygraphHQ/shannon): Shannon is an AI pentester for web applications and APIs. It analyzes your source code, identifies attack vectors, and executes real exploits to prove vulnerabilities before they reach production.
- [morluto/rea](https://seerepo.com/r/morluto/rea): Reverse engineer anything with agents, from app behavior down to native binaries.

## What they share and what sets them apart

- In common: @clack/prompts, Ajv, ajv-formats

- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
