Robin turns engineering work into a repeatable system: investigate a codebase, implement changes, validate them, and deliver a pull request.
It also reviews pull requests, learns repository-specific review preferences, monitors CI, and responds to feedback.
Built by LangChain, it is open source and deployable in your infrastructure.

> [!NOTE]
> **Under active development.**
> Expect breaking changes and rough edges.
> We’re not accepting issues or external contributions at this time.
> You’re welcome to explore and fork the code, but correctness, stability, and compatibility are not guaranteed.
>
> If you really want to deploy it yourself, follow the [installation guide](docs/INSTALLATION.md).
> Deploying it as is requires [Managed Deep Agents](https://docs.langchain.com/langsmith/python/managed-deep-agents-overview), which runs its agent; without it, we recommend forking and adapting the code to your own runtime.

```

- **Build:** Investigate repositories, edit code, run focused validation, and open or update pull requests.
- **Parallelize:** Use subagents for research and independent work.
- **Review:** Run on-demand or opt-in automatic reviews, publish findings to GitHub, and learn from historical feedback.
- **Investigate:** Use read-only PR chat to understand a change without implementing changes.
- **Operate:** Schedule recurring tasks and monitor opted-in PRs with `/baby-sit`, diagnosing failures and rerunning only evidence-backed flaky jobs.
- **Customize:** Choose models, reasoning effort, instructions, skills, integrations, and sandbox providers.

Start and continue work from the **dashboard**, **GitHub issues and PR conversations**, or **Slack**.
