## Tools (as reported by the server, not verified)

- `compile\_offer\_policy`: Turn a seller's offer, described in plain words, into negotiation RULES an AI agent cannot break. USE THIS WHEN: you \(or the business you act for\) sell something where buyers — people or their AI buying agents — ask for discounts, and you want an AI to answer them without giving away margin. Describ
- `draft\_negotiation\_reply`: Draft the seller's reply to a buyer's message — the offer is decided by the SNHP engine INSIDE the policy. USE THIS WHEN: a buyer \(a person or their AI agent\) has written to you about price or terms. Pass the policy \(from compile\_offer\_policy\) and their latest message exactly as written; pass back t
- `check\_offer\_policy`: Check an edited negotiation policy: returns \{ok, policy, issues, summary\}. No model call, free. USE THIS WHEN: you changed a policy from compile\_offer\_policy \(a floor, an option, a forbidden combination\) and want to know it is valid and what it now allows before using it in draft\_negotiation\_reply.
- `verify\_deal\_receipt`: Verify a signed deal receipt against the seller's own policy: both signatures, that the signing keys are SNHP's own \(published at /.well-known/ucp\), the policy digest, and every rule re-checked from the package. Returns \{ok, problems, checks, signed\_by\_snhp, signatures\}. Free, no model call.
