YAMS Blackboard (VS Code)

VS Code extension for multi-agent coordination on top of YAMS.

This extension ports the OpenCode blackboard plugin to VS Code and talks to the YAMS daemon directly over Unix domain socket IPC (protobuf + framed transport). It registers bb_* Language Model tools and an @blackboard chat participant.

Requirements

• VS Code ^1.95.0
• GitHub Copilot Chat enabled (for chat participant + LM tools)
• YAMS daemon running locally (the extension connects via Unix domain socket)

Usage

Open the Chat view and message the participant:

@blackboard show stats
@blackboard show recent activity
@blackboard list pending tasks

You can also invoke the tools directly (the exact tool names are bb_*).

Autonomous agent identity

The extension maintains a default agent identity (persisted per workspace) and will register it on the blackboard when the daemon is connected.

• Tools that accept agent_id / created_by will default these fields when omitted.
• If you want a custom identity (e.g., to emulate an external agent), call bb_register_agent and then pass that agent_id explicitly.

Development

npm install
npm run watch

Then launch the extension via VS Code's extension host (F5) from this folder.

Proto regeneration (if YAMS IPC schema changes):

npm run proto:generate

Notes

• This extension is designed to degrade gracefully if the daemon is not running; tools will fail with a connection error until the daemon becomes available.
• The extension bundles via esbuild into dist/extension.js.
