Agent skill

For agents that cannot mount an MCP server but can read a URL and make HTTP calls (Claude Code skills, Cursor rules, OpenClaw, custom LangChain or AI SDK agents), the skill is a markdown file that teaches the discover → inspect → run loop.

Install

set up https://cracked-ai-pearl.vercel.app/SKILL.md

Paste that to your agent. It fetches /SKILL.md, asks you for your key once, stores it as CRACKED_API_KEY, and from then on reaches for Cracked whenever a task needs external data or a paid API.

Claude Code skill directory

What the skill contains

• Base URL and auth header.
• The three calls with request and response shapes.
• Rules: a 404 from the provider is “no data”, not an error; a BLOCKED run means pick another tool; never fabricate output.
• Where to send the user when balance runs out.
