Use a skill

sphinxstack skills are plain SKILL.md files. They work with Codex, Claude Code, Cursor, Copilot, Gemini, ChatGPT, and any other agent that can read a file or URL. If you are not sure what a skill is yet, start with the plain-language explanation.

The short path

1. Choose a skill.
2. Open it in your agent, give the agent its raw URL, or copy the file in.
3. Describe the real task. The skill supplies the process, rules, and checks.
4. Keep the skill loaded until its definition of done is satisfied.
