rio
Rio is a fully autonomous, one-shot coding agent. It has no built-in interactive TUI, no conversation history, no human steer in the middle and no follow-up turns. Start a task and Rio runs until the task completes or aborts.
Getting Started
Install via uv:
uv tool install rio
Usage
Login to your preferred providers:
rio login anthropicrio login github-copilotrio login codex- ...
Run a adhoc task:
rio run "Fix gh issue 123."
Rio keeps its State in SQLite and executes independent Python scripts through uv.
Committed work survives restart; interrupted scripts return UnknownExecution for
inspection. See Architecture.
Run a predefined workflow:
rio run task.md
The workflow is to write the task in a Markdown file, then run Rio against it.
You can add a short instruction when invoking it:
uv run rio run "Follow feature.md, run the tests, and finish the implementation"
Use --provider NAME --model MODEL to choose a provider and a model.
Rio prints a compact human transcript by default. Use --output json for one JSON
event per line. Each human-mode run prints a session id; continue it with
rio run --resume SESSION_ID. Start a new run for a new task.
Documentation
See the documentation for tutorials, guides, command-line reference, and an explanation of Rio's architecture.
Development
uv run pytest
uv run ruff check .
To run the Lean 4 verification, install elan and build the pinned toolchain from the repository root:
cd tests/lean && lake build
See the Lean behavior models for their scope and limits.
rio.aistreams model responses from multiple providers.rio.agentowns SQLite state, immutable cells, workers, and recovery.rio.codingsupplies provider configuration, credentials, and MCP clients.rio.cliruns coding tasks.
