How I Turned Slack Into an AI Teammate That Opens Pull Requests

How I Turned Slack Into an AI Teammate That Opens Pull Requests

Short summary

The author built Slack2PR, an AI coding teammate that turns Slack messages into GitHub pull requests. It uses Hexabot for workflow orchestration, Google Gemini for intent classification and coding, and TanStack AI Sandboxes for isolated Docker workspaces. The design keeps the workflow in control by dividing tasks into explicit stages—classify, gather requirements, plan, implement, test, and open PR—rather than using a single mega-prompt.

  • •Slack2PR converts Slack messages into GitHub PRs via an agentic workflow
  • •Uses Hexabot, Gemini, TanStack AI Sandboxes, and interchangeable coding adapters
  • •Workflow is split into explicit stages for observability and control

Generated with AI, which can make mistakes.
