Overview

What is agent-coherence?

A coherence guard for shared files: when two agents (or sessions) write the same artifact, the stale writer is denied instead of silently overwriting — then reacquires and retries. Same protocol across LangGraph, CrewAI, AutoGen, the OpenAI Agents SDK, plain files (CoherentVolume), and any MCP client (stale-write-guard-fs).

How to use it

MCP: pip install "agent-coherence[mcp]", then run stale-write-guard-fs. Library: pip install agent-coherence and use CoherentVolume, or the CCSStore LangGraph drop-in.

Key features

  • MESI single-writer ownership + invalidation — a stale write is denied fail-closed
  • Optimistic commit-CAS for concurrent same-key writers
  • Read-generation fence for crash-reclaimed writers
  • Five safety invariants machine-checked in TLA+ (make tla-check in CI)
  • MCP server (5 tools), LangGraph/CrewAI/AutoGen adapters, Claude Code plugin

Honest scope

Single-host today: concurrent same-key writers on one host are covered; cross-host fencing is on the roadmap, demand-gated.
