name: openclaw-interchange description: Shared .md interchange library for OpenClaw skills — atomic writes, deterministic serialization, YAML frontmatter, advisory locking, and schema validation. The foundation all other OpenClaw skills build on.

@openclaw/interchange

The shared library that powers agent-to-agent communication via .md files.

Usage

import { writeMd, readMd, acquireLock } from '@openclaw/interchange';

// Write an interchange file atomically
await writeMd('ops/status.md', { skill: 'crm', status: 'healthy' }, '## Status\nAll systems go.');

// Read it back
const { meta, content } = readMd('ops/status.md');

Key Features

• Atomic writes (tmp + fsync + rename)
• Deterministic serialization (sorted keys, stable YAML)
• Advisory file locking with stale lock detection
• YAML frontmatter parsing
• Schema validation
• Circuit breaker pattern
• Generation tracking + content hashing
