What problem does it solve?

Running multiple Claude Code sessions in parallel leaves you manually syncing context because agents cannot see or message peer sessions.

Who is it for?

Indie builders who routinely open more than one Claude Code session and want on-machine session-to-session messaging.

Skip if: Teams that need hosted chat, audit logs, or cross-machine agent orchestration without a local broker.

What do I get? / Deliverables

After you add the marketplace plugin, sessions can discover each other locally and exchange messages so parallel agent work stays aligned without constant copy-paste.

BuildAgent skills & templates

Inter-session messaging is installed when you are actively building with more than one agent window and need coordination, not during idea or launch work. agent-tooling is the shelf for plugins that extend how coding agents talk to each other or to local infrastructure.

How it compares

Local inter-session messaging plugin, not an MCP server or a general team collaboration suite.
