CodeRabbit Agent for Slack: One agent for your entire Software Development Lifecycle. Right in Slack.
CodeRabbit Agent is an AI-powered software development assistant that lives inside Slack and helps engineering teams manage the entire software development lifecycle in one place. It can investigate issues, plan features, generate code, open pull requests, automate workflows, and pull context from tools like GitHub, Jira, Notion, Datadog, and AWS - all directly within Slack conversations. The platform is designed around “Agentic SDLC,” where AI agents actively participate across planning, coding, testing, deployment, and maintenance while preserving organizational knowledge and working within governance controls defined by the team.

Introducing CodeRabbit Issue Planner! ✨

AI agents made coding fast but planning messy.
Turn planning into a shared artifact in your issue tracker, grounded in related issues and decisions. Review prompts as a team, then hand them off to an agent!

Claude or Cursor can generate a plan in seconds, but they won’t know about the related issue from last sprint, the architectural decision buried in comments, or the refactor already in flight. So they confidently plan the wrong thing. Plans like these either lead to an iterative prompting time suck, or are subtly wrong in ways you only discover during implementation or review, after assumptions harden and rewrites erase all your AI speed gains.

CodeRabbit Issue Planner turns planning into a shared artifact in your issue tracker.

Plans are grounded in related issues, past decisions, and context.
Teams align with prompt reviews before code exists.
Plans are then handed off to any agent.

By aligning on intent up front, teams reduce AI slop and rework, save time, and make AI usable for everyone… not just a few “prompt whisperers” on the team.

So, you ACTUALLY move faster with AI.

We're excited to announce the launch of the Docstrings feature! This functionality allows developers to generate docstrings on a pull request. By commenting @coderabbitai generate docstrings on any pull request, you can automatically generate docstrings for functions in the code changes.

Once sent, CodeRabbit will perform the following actions:

All functions that are in the pull request's changes will be fetched using ast-grep
Docstrings will be generated for the functions where they are missing or incomplete
These docstrings will be committed in a new branch in the same repository
CodeRabbit will open a pull request from this new branch to the existing pull request
