- [bee-san/Ciphey](https://seerepo.com/r/bee-san/Ciphey): ⚡ Automatically decrypt encryptions without knowing the key or cipher, decode encodings, and crack hashes ⚡
- [openai/codex](https://seerepo.com/r/openai/codex): Lightweight coding agent that runs in your terminal

## What they share and what sets them apart

- In common: SQLite, Tokio, rmcp, log
- Only in Ciphey: rusqlite, env_logger
- Only in codex: axum, lru, Sentry, tower, objc2-app-kit, objc2-foundation, Ratatui, crossterm, keyring, hmac, png, image, pulldown-cmark, zip, schemars, Pydantic, tracing, tracing-subscriber, tracing-appender

- 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.
