Footgun

Your AI agent knows how the API works. Footgun tells it how it breaks.

Footgun is a dated, verified registry of the traps that docs leave out: silent deprecations, quiet limits, settings that save but do nothing. Your coding agent checks it before it writes the code. Browse every trap at getfootgun.com.

Install in Claude Code

/plugin marketplace add getfootgun/footgun
/plugin install footgun@footgun

Lookups work without an account. To file and confirm traps, create an API key at getfootgun.com/account and enter it when the plugin asks.

The data

data/traps/<tool>/<trap>.json holds every public verified trap: symptoms, cause, fix, the date it was last verified, and its trust score. data/providers.json lists the tools covered. The data is exported from getfootgun.com and updated as traps are added, confirmed or retired.
