# Agent Skill

Last updated: 2026-10-10

`attestpage-check-sources` is an Agent Skill: a `SKILL.md` file that tells an agent when to check a source with AttestPage (before it quotes a page, cites a URL or installs a package an LLM suggested), how to call the sample, the trial or the paid route, and how to read the verdict. Clients that read `SKILL.md` files, such as Claude, Codex and Cursor, load its name and description up front and the rest only when a task matches.
