## Skills
- **Create Ricardian Contract** — Generate a legally-structured dual-format Ricardian Contract from a template. Requires template slug, parameters, and principal declaration. Burns the template 
- **Browse Contract Templates** — List available contract templates with parameter schemas. Categories: delegation (d1-d3), commerce (c1-c3), and consumer (a1-a3). Use this before create_contrac
- **Get Contract Details** — Retrieve a contract by ID (amb-YYYY-NNNN), SHA-256 hash, or UUID. Returns both human-readable and machine-parsable formats, so retrieval preserves the dual-form
- **Verify Contract Integrity** — Verify a contract's SHA-256 hash to confirm it hasn't been tampered with. Verification is the point at which legibility becomes provable: a matching hash means 
- **Check Contract Status** — Check contract lifecycle status (draft/active/terminated/etc) and amendment chain. Amendments are bilateral and themselves dual-format — the chain stays legible
- **Agent Handshake** — Initiate a handshake on a contract on behalf of the delegating principal. Requires API key with registered delegation. Principal must approve separately. The ha
