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

The piece describes building a Slack bot that functions as a lightweight AI engineer: you describe a change in a Slack message, the agent writes the code, and it opens a pull request. No custom UI, no new tool to adopt — Slack is the interface. The pattern is solid for small teams that already live in Slack and want to delegate repetitive PR work without standing up a full agentic IDE integration. What it is not is a polished product — this is a weekend build documented as a tutorial, and the reliability of the agent on anything beyond trivial changes is left as an exercise. The GitHub integration is the interesting part; the Slack surface is mostly convenience. If a SaaS team of 2-5 already uses something like Copilot Workspace or Cursor for this, there is probably not enough new here. If they do not, the pattern is worth stealing. -> Best for: SaaS team of 2-5 wanting a low-friction code-agent entry point
