Runaway Guard

Agent skill
1 skill

Use when writing or reviewing code that calls a paid AI / inference API in a loop, queue, retry path, agent step, webhook handler, or background job — Fal.ai, Anthropic, OpenAI, Replicate, ElevenLabs, Together, Groq, Cohere, Mistral, fal-client, @anthropic-ai/sdk, openai, replicate. Treats dollar cost as a third complexity dimension alongside time and space. Forces writing a per-run $-cap, a per-day $-cap, a max-iterations bound, and a concurrency limit BEFORE the call site is written — and forces a matching hard cap at the provider dashboard so a code bug cannot bypass it. The canonical failure is a $200 overnight bill from a retry loop that "obviously terminates" but did not. Pairs with invariant-guard (termination is now a wallet invariant) and complexity-cuts (when the runaway already shipped).
