Runaway Guard

Q: What is a Claude Code skill and how does the Runaway Guard skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Runaway Guard is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.

ai:claude type:review

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).

From the source SKILL.md

Every loop has time complexity and space complexity. A loop that calls a paid API has a third: dollars per execution. The model tracks the first two automatically. It does not track the third, so it ships code where a single bug — a retry without bound, a stream reconnect storm, an agent that re-queues itself, a webhook that fires the same job twice — silently spends real money.

What this skill does

Runaway Guard is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/runaway-guard/ and loads when your prompt matches the skill's trigger.

When to invoke it: 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.
