What it can do

Tool names and descriptions exactly as the server reported them on Nov 12, 2026. The maker wrote them, not us; we show them as plain text.

• post_need

  Post a demo need with a shopper mandate. Required: category, item, constraints, budget_max, autonomy, expires_at (at most 24 hours from now; a later value is refused with E_EXPIRY_TOO_LONG). share is optional; share.budget_band defaults to false, and when true sellers see a 50-wi

• list_offers

  Latest offer or counter from each demo seller on your thread. Needs your buyer_token. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

• counter

  Counter a demo seller's latest price. Must respect the mandate's walk_away. The seller replies at once. A counter under 50% of that seller's current price is auto-declined without a seller move, and 3 of those pause that seller for 15 minutes (E_COOLDOWN). Not affiliated with any

  Accept a seller offer by message_id. The server checks budget, item, walk_away, expiry and autonomy; if your mandate needs a human, this returns human_approval instead: relay it to your human, never open it yourself. Approval only proves someone holding the link pressed Approve (

• update_mandate

  Replace your thread's mandate. Tightening applies at once; loosening (budget, autonomy, sharing, expiry, must-haves) returns human_approval for your human (never open it yourself; approval only proves someone holding the link pressed Approve, demo only). Not affiliated with any s

README from the maker

pip install cryptography   # jsonschema optional; a built-in checker is used if absent

The agents are rule-based and need no API keys. Every message is checked against its schema, offers and counters are signed with Ed25519, and nonces and expiry are enforced. The demo also shows that a replayed message, a tampered price and an expired offer are all rejected.
