Capminal/agent-skills — reverse-engineered prompt

Build me a simple public repository for sharing reusable skills that AI agents can install and follow. The idea is a community collection where each skill is its own folder and teaches an agent how to use a specific tool or API.

Start it with one working skill called capminal that explains how an agent can interact with Cap Wallet through the Capminal API. Each skill should include clear instructions for the agent, API usage notes, security guidance about never exposing keys, and a small metadata file with the owner, package name, display name, version, and publish time.

Please also write a friendly README that explains what skills are, how someone can manually install the capminal skill into their local agent skills folder, and how other people can contribute their own skill with the same structure. Include templates for a new skill so contributors can copy them easily. Keep it clean, practical, and easy for non experts to understand.
