A Slack bot that integrates with Anthropic's Claude Code CLI, enabling teams to interact with Claude Code directly from Slack threads.
- Per-thread isolated workspaces with git repository management
- Spawns
claudeCLI processes to handle tasks asynchronously - Queue-based execution with Redis persistence (falls back to in-memory)
- Full oh-my-claudecode orchestration modes: autopilot, ralph, ultrawork, ecomode, and more
- Responds to slash commands, @mentions, and threaded messages
- Docker and bare-metal deployment options
- Node.js 22+
- pnpm
- Claude Code CLI installed and authenticated
- A Slack app with Socket Mode enabled and the required bot scopes

You can also mention the bot (@SilverBack) or reply in a thread to interact with Claude directly.
SilverBack uses the @slack/bolt library in Socket Mode to receive events without requiring a public HTTP endpoint. When a message is received, it is placed on a queue (backed by Redis when available). A worker pool dequeues tasks and spawns claude CLI processes, each isolated in a per-thread workspace directory with its own git state. The oh-my-claudecode plugin is loaded into each Claude session, providing orchestration modes such as autopilot, ralph, and ultrawork. Responses stream back to the originating Slack thread in real time.
