This adds a new skill, zambo-receipts, under skills/zambo-receipts/SKILL.md.

What it does: it teaches Copilot how to verify an execution receipt. When an agent does work through Zambo (the verifiable work layer for AI, one MCP endpoint at https://zambo.dev/mcp with 153 tools), every call returns a verifiable AER-1 receipt holding the SHA-256 digest of the saved output. The skill walks through checking that receipt against the public verify endpoint, recomputing the digest, and stating plainly what a match proves and what it does not. It also covers handover receipts, the pair issued when work is wrapped up in one AI and picked up in another.

Why it belongs here: the catalogue already has skills for reviewing agent actions before they run. This one covers the other side, checking the record after the work is done, and nothing in the current 448 skills covers execution receipts or AER-1 (IETF draft-zambo-aer1-26).

Paid-service note, per the repo guidance on submissions involving paid services: verification itself is free and needs no account. Anyone can check a receipt at https://zambo.dev/verify/ or through the API endpoint the skill uses, whether or not they use Zambo. The skill is MIT licensed and already published in the open at zambodotdev/zambo-skills and on ClawHub.

The folder name matches the frontmatter name, and the file is self-contained with no bundled assets. Happy to adjust wording or scope on review.
