Nerva Code brings NERVA's settlement and its verify verdict to your own codebase. Connect a provider, hand it a task, and it works the repo the way an agent should, not by guessing.
Nerva Code is the coding agent from Dacely, in your terminal. It is the code surface of NERVA, the accuracy engine for open models, and it points the same settlement and the same verify verdict at your own repository.
Connect any provider, the NERVA engine you run on the GPU you already own or any OpenAI compatible endpoint, hand it a task, and it reads and works the codebase the way an agent should, not by guessing at an API it half remembers. Nerva Code is a fork of opencode, so everything opencode already does it does too. What NERVA adds is the discipline that turns a guess into a checked result: a population of reasoning that converges on the right change, and a done that is a verdict, not a feeling.
Nerva Code runs where you code and talks to whatever model you point it at. Run the NERVA engine locally for tier one results on hardware you own, or connect any OpenAI compatible provider. There is nothing to rent and nothing to send anywhere you did not choose.

- 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.
