Replicas integrates with Slack as a bot you can mention in channels. Mention @Replicas to start a task, and it spawns a workspace to complete the work and replies directly in the thread.

​
Setup

  1. Go to Integrations settings
  2. Click Connect Slack and authorize for your workspace
  3. Invite @Replicas to the channels where you want to use it
Ensure you have at least one repository configured before mentioning Replicas.

​
How It Works

When you mention @Replicas in a channel:
  1. Replicas adds an 👀 reaction to acknowledge your message
  2. If multiple repositories are configured, you’ll see a dropdown to select which one to work on
  3. A workspace is created for the task
  4. The agent sends a brief acknowledgment, then works on your request
  5. When done, the agent replies in the thread with results (typically a PR link)

​
Repository Selection

If your organization has multiple repositories, you can:
  • Use the dropdown: Replicas will prompt you to select a repository
  • Specify inline: Add [repo:name] to your message (e.g., @Replicas [repo:backend] add a login page)
The [repo:name] syntax uses inclusive matching, so [repo:api] would match my-company/api-server.

​
Thread Conversations

Each Slack thread is linked to one workspace. Follow-up mentions in the same thread route to the same workspace, so the agent remembers previous context. If the workspace is deleted and you mention @Replicas again in that thread, a new workspace is automatically created.

​
Context

The context provided to the agent includes:
  • Your message (with bot mention stripped)
  • Full thread history (all previous messages in the thread)
  • Channel name
  • User names of participants

​
Intended Usage

Slack works best for quick requests and iterative conversations:
  • Start tasks with a brief description
  • Follow up in the same thread to refine or add requirements
  • The agent responds directly in Slack, making it easy to share progress with your team
Add /plan in your message to request a planning-only response with a plan link. See Plan Mode.
