@peac/adapter-openclaw captures every tool call an OpenClaw agent makes and produces tamper-evident signed receipts. It uses a two-stage pipeline: a sync capture stage (under 10ms) appends hashed evidence to an append-only spool, and an async background emitter drains the spool, signs each entry, and writes individual receipt files. All inputs and outputs are SHA-256 hashed by default; plaintext is only captured for explicitly allowlisted tools.

How Do I Use It?

Quick start with activate()

import { activate, generateSigningKey } from '@peac/adapter-openclaw';

// Generate a signing key (one-time setup)
const key = await generateSigningKey({ outputDir: '.peac' });

// Activate the plugin
const plugin = await activate({
  config: {
    signing: {
      key_ref: `file:${key.keyPath}`,
      issuer: 'https://my-org.example.com',
    },
  },
});

plugin.instance.start();
// Records are now captured automatically via hooks.

Map individual tool call events

import { mapToolCallEvent } from '@peac/adapter-openclaw';

const result = mapToolCallEvent(event);
if (result.ok) {
  console.log('Captured action:', result.action);
  console.log('Warnings:', result.warnings);
}

Use lower-level components directly

import {
  createHookHandler,
  createReceiptEmitter,
  createBackgroundService,
  createSessionHistoryTailer,
} from '@peac/adapter-openclaw';

Integrates With

@peac/adapter-core (Layer 4): Shared Result types
@peac/capture-core: Capture session, spool store, and deduplication
@peac/capture-node: File-system spool store and deduplication index
@peac/crypto (Layer 2): Ed25519 signing and SHA-256 hashing
@peac/kernel (Layer 0): Wire constants and types
@peac/schema (Layer 1): Receipt claim schemas

For Agent Developers

If you are building an AI agent on OpenClaw that needs verifiable activity records:

Use activate() for the simplest setup; it wires all components from a single config object
Use generateSigningKey() or the peac-keygen CLI to create a signing keypair
Use env: key references in CI/CD and file: references for local development
The plugin exposes tools (peac_receipts.status, peac_receipts.verify, peac_receipts.query, peac_receipts.export_bundle) for the agent to inspect its own receipt state
