PACT — Protocol for Agent Constitutional Trust

*"Negotiate before you integrate."*

Use this skill when two agents from different systems need to establish trust before transacting. PACT provides a five-chamber protocol that handles the full lifecycle from first contact to secure session.

Five Chambers

import { pact } from '@godman-protocols/sdk';
// Chamber 1 — Public Entry Gate: rate limiting, DID resolution
// Chamber 2 — Identity Analysis: ERC-8004 verification, trust score → session ceiling
// Chamber 3 — Intent Analysis: 3-pass prompt injection scanner, coherence check
// Chamber 4 — Negotiation Room: capability declaration, payment terms, EIP-712 dual signature
// Chamber 5 — Secure Channel: capability-locked session token via HMAC(deal_hash + agent_did + expiry)

Trust Score → Session Ceiling

| Score Range | Ceiling | Duration | Price Multiplier | |---|---|---|---| | 85-100 | FULL | 24h | 1.0x | | 70-84 | STANDARD | 4h | 1.2x | | 50-69 | RESTRICTED | 1h | 1.5x | | 30-49 | MINIMAL | 15m | 2.0x | | <30 | REJECTED | — | — | | Unknown | PROVISIONAL | 15m | 2.5x |

When to Use

First contact between agents from different systems

Establishing trust before any data exchange or payment

Constitutional negotiation (what constraints each agent requires)

Creating capability-locked session tokens with automatic expiry

Notes

SOUL constraints override PACT sessions — never use PACT to bypass safety rules

Every PACT session produces an EAS attestation on Base (on-chain audit trail)

Integrates with LAX for discovery and DRS for deal receipts
