- [JuliusBrussee/caveman](https://seerepo.com/r/JuliusBrussee/caveman): 🪨 why use many token when few token do trick. Viral skill + proxy for coding agents that cuts 65% of tokens by talking like a caveman.
- [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.

## What they share and what sets them apart

- In common: @clack/prompts, typebox, Ajv
- Only in caveman: net/http, pgx, SQLite, Postgres, Anthropic, MCP, ai, @ai-sdk/provider, LangChain, @mastra/core, earendil-works
- Only in shannon: Pi, handlebars, js-yaml, ajv-formats

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- 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.
