Dated, verified API breakages for coding agents, plus a local scan for them in your existing code.
Footgun 为编码助手提供带日期、经核实的第三方 API 陷阱登记库，让它在写代码前或报错后查证已知的破坏性变更。
Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

}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.
On 17 coding tasks that touch recent API changes, run 5 times each, Claude Code got the code right on the first try 82% of the time with Footgun and 52% without, at 18% lower cost per working result. On older APIs the model already knows, it made no difference. The method and full results are at getfootgun.com/benchmark.
89 of 200 still use GitHub Actions built for Node 20, which GitHub now runs on Node 24. 93 have at least one problem that breaks now or will break, counting only rules a person checked against real code. The method and results are at getfootgun.com/scan.
Lookups and filing work without an account. Filed traps are checked against official sources before anyone else sees them. To confirm traps, create an API key at getfootgun.com/account and enter it when the plugin asks.
The plugin also adds /footgun:scan, which checks your project on your machine for known traps in the exact package versions you use. Your code never leaves your machine; only the rule download and an anonymous count of findings are sent. Turn the plugin setting share_learnings off to stop the count and the filing of fixes your agent learns. The setting auto_context adds a short note of those traps at the start of each session. It is on by default; set it to false to turn it off.
cli/ holds the same scanner as a command, published on npm as @getfootgun/footgun: npx @getfootgun/footgun scan [path] (Node 20 or later). Add --json for machine-readable output or --fail-on breaks to fail a CI job.
Launch checks come first, under "Before you launch": problems that leak data or run up a bill, such as secret keys in browser code or a Supabase table with RLS off. Ones that live in a dashboard rather than in code are listed as items to check yourself whenever you use that package.
After a scan it prints a dated README badge: "no known API traps" only when the scan found nothing apart from launch reminders, "scanned" otherwise.
With a Pro or Team key, scan --watch adds the project to Footgun Watch, which lists new and changed traps that match your exact package versions on your Projects page. It sends the project name, the folder of each package file, your package names and versions, and the trap, file and line of each finding, never code. See getfootgun.com/docs.
In GitHub Actions, use GetFootgun/scan-action. It lists findings in the job summary, can fail the job on breaks or will-break, and with watch: "true" sends the project to Footgun Watch.
For Cursor, Codex and other clients, point them at https://getfootgun.com/api/mcp (streamable HTTP). Add the header Authorization: Bearer <your key> to file and confirm traps.
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.

Look up traps for a provider
Call before writing code against a third-party API, platform, or AI tool. Returns verified, dated failure modes with fixes.
contextsurfaceprovider必填include_staleSearch traps by error text
Call when a call to a third-party service fails. Paste the error text. Returns the closest verified traps with fixes.
providererror_text必填include_staleFile a new trap
Draft a trap after a failure was fixed. Private by default with a Pro or Team key. Public filings are checked automatically against official sources and published only when an official source confirms them. A reviewer can still act on any filing. Citing the provider's official documentation or changelog in sources helps. No API key needed. Set visibility to public to submit to the public registry.
