- build - Default, full-access agent for development work
- plan - Read-only agent for analysis and code exploration
- Denies file edits by default
- Asks permission before running bash commands
- Ideal for exploring unfamiliar codebases or planning changes
Also included is a general subagent for complex searches and multistep tasks.
This is used internally and can be invoked using @general in messages.

If you are working on a project that's related to ultrawork-code and is using "ultrawork-code" as part of its name, for example "ultrawork-code-dashboard" or "ultrawork-code-mobile", please add a note to your README to clarify that it is not built by the ultrawork-code team and is not affiliated with us in any way.
It's very similar to Claude Code in terms of capability. Here are the key differences:
- 100% open source
- Not coupled to any provider. Although we recommend the models we provide through ultrawork-code Zen, ultrawork-code can be used with Claude, OpenAI, Google, or even local models. As models evolve, the gaps between them will close and pricing will drop, so being provider-agnostic is important.
- Out-of-the-box LSP support
- A focus on TUI. ultrawork-code is built by neovim users and the creators of terminal.shop; we are going to push the limits of what's possible in the terminal.
- A client/server architecture. This, for example, can allow ultrawork-code to run on your computer while you drive it remotely from a mobile app, meaning that the TUI frontend is just one of the possible clients.
