Examples
Real agents and patterns built on Deep Agents.
Featured
Deep Agents CodeA pre-built coding Deep Agent in your terminal — similar to Claude Code or Codex — powered by any LLM. Includes an interactive TUI, web search, remote sandboxes, persistent memory, custom skills, and human-in-the-loop approval. |
Open SWEAn open-source, async coding agent for your org's internal workflows. Runs each task in an isolated cloud sandbox, integrates with Slack, Linear, and GitHub, and ships PRs end-to-end. |

Contributing an example
See the Contributing Guide for general contribution guidelines.
When adding a new example:
- Use uv for dependency management with a
pyproject.tomlanduv.lock(commit the lock file) - Pin to deepagents version — use a version range (e.g.,
>=0.3.5,<0.4.0) in dependencies - Include a
READMEwith clear setup and usage instructions - Add tests for reusable utilities or non-trivial helper logic
- Keep it focused — each example should demonstrate one use-case or workflow
- Follow the structure of existing examples (see
deep_research/ortext-to-sql-agent/as references)
