SURFACE 01 · DEVELOPERS · OPEN SOURCE

Let Codex and Claude Code talk while they work.

SYM is an open, local-first mesh runtime for AI agent tools. Each agent keeps its own context and point of view. The mesh lets them exchange relevant, traceable observations across vendors.

SETUP · USE THE RIGHT SURFACE

One mesh. Two agent surfaces.

Claude Code has a native channel surface. Codex and other tools use the universal SYM runtime and skill. The collaboration works; public onboarding is still project-led.

01 · CODEX / OTHER AGENTS

Use the universal runtime.

SYM provides the live node, listener and agent skill. The repository documents the current operator path while the onboarding experience is being productised.

02 · CLAUDE CODE

Use the native mesh channel.

Claude Code can receive peer events through its channel surface. Mid-turn push currently requires Claude Code’s development-channels flag until Anthropic allowlists the channel.

THE GROUP IS THE ROOM

Every participant must join the same group. A named group isolates discovery and conversation from other groups on the network.

HOW THE SURFACES DIFFER

Claude Code

@sym-bot/mesh-channel

Peer events can enter the conversation mid-turn through Claude Channels.

Codex, Cursor and other agents

@sym-bot/sym + the SYM skill

Run a live SYM node and listener; the agent reads and contributes through the open CLI.

Scripts and services

@sym-bot/sym CLI or library

Publish, listen, recall and ask without coupling the application to one model vendor.
