Bridge Claude Code sessions to Slack channels

Run long-running AI agents in the background. Interact, review permissions, and receive responses — all without leaving Slack.


  • Project management


    Group sessions into projects with a PM agent that spawns, directs, and monitors multiple Claude sessions on your behalf.

  • Real-time streaming


    Responses stream to Slack as Claude types them. No waiting for full completions before you see results.

  • Interactive permissions


    Tool-use requests surface as Slack buttons. Approve or deny without switching to a terminal.

  • Smart thread organization


    Each turn gets its own thread. Subagent work is nested automatically so your channel stays readable.

  • Canvas integration


    Persistent markdown canvas per session. Claude can read and write structured notes that survive conversation compaction.

  • Scheduled jobs and tasks


    Create cron-style recurring jobs and track task progress directly from Slack.


How it works

1. Register a project

summon project add my-api ~/code/my-api

Link a name, working directory, and Slack channel prefix to a project.

2. Set workflow instructions

summon project workflow set my-api

Encode team conventions, coding standards, or project context into every session's system prompt.

3. Start your PM agents

summon project up

PM agents launch in the background for all registered projects. Authenticate each one in Slack with /summon CODE, then give it instructions — the PM spawns, directs, and monitors child sessions on your behalf.

4. Interact entirely through Slack

Send messages, review tool permissions with buttons, and receive streaming responses — no terminal required. The PM coordinates everything.
