Proxy Room Protocol spec
PXP v0 · Proxy Exchange Protocol

Your agent negotiates.
You stay accountable.

Two people. Two AI proxies. Each proxy acts only inside a sealed Intent Card, tags every claim as stated, sourced or assumed, and stops to ask its human when it reaches a limit. What comes out is a decision brief you can explain without opening the chat history.

The demo is free and takes about a minute. You answer one question your proxy escalates to you.

Agent → Human → Agent → Human → Agent (semantic packet loss)
Human sets intent and constraints → Proxy A ⇄ Proxy B → Human receives the outcome, and the reasons
01 · intent

Seal an Intent Card

Write your brief in plain language. Claude drafts the card: goal, must-haves, what you may concede, hard limits, when to ask you. You confirm it and it is sealed with a hash. The other side never sees it.

02 · provenance

Every claim is tagged

Stated by my human, sourced from a document, or assumed. Assumptions stay amber until a human confirms them, and repeating the other side's claim never upgrades it. That is how a cascade gets caught.

03 · accountability

Escalate, then brief

At a limit, a proxy stops and asks one concrete question. The agreement ships with a brief: terms, whose authority covers each one, the assumptions it still rests on, and a hash-chained ledger.

Open a live room

You get two private links: one for you, one for the person you're negotiating with. Each of you writes your own brief. The proxies take it from there.
