uv-agent 0.5.2

Experimental Python-runner coding agent with a Textual TUI

uv-agent

简体中文

uv-agent is a portable coding agent with a Textual TUI. Its only external action surface is run_python: the model submits Python scripts to a managed uv run runner, and those scripts do the actual work. This single-tool design keeps agent behavior consistent across platforms—any OS with Python and uv behaves the same way.

Public APIs, config fields, and runtime behavior may still change as the project evolves.

Install And Run

Prerequisites
You need uv and ripgrep installed on your system. uv is the Python package and project manager used to run the agent; ripgrep is used for fast file-content searches inside the workspace.

Run the latest published package:

uvx uv-agent@latest

Run from a local checkout:

uv run uv-agent

Ask a single prompt without opening the TUI:

uvx uv-agent@latest ask "Reply with exactly: ok"

Resume an existing thread:

uvx uv-agent@latest ask --thread thr_xxx "Continue from here"

Configuration

User config lives at ~/.uv-agent/config.json. A project can override it with .uv-agent/config.json; that project-local directory is ignored by git. Keep API keys in environment variables or ignored local config.

API compatibility
This project supports three API formats — set api on your model config:

api value	Format	Status
"chat_completions"	OpenAI Chat Completions API	✅ Primary (fully supported)
"responses"	OpenAI Responses API	⚠️ Experimental — may have bugs
"anthropic_messages"	Anthropic Messages API	⚠️ Experimental — may have bugs

Issues and PRs are welcome for any format!Example configuration:

  }
}

Use /config in the TUI to switch the default level, language, and automatic compression. Set ui.language to zh-CN for a Chinese UI. Completion notifications can be configured under ui.completion_notification. Non-Windows platforms use the terminal bell for completion sound.

See configuration for all supported options and config.example.json for a detailed example.

Core Ideas

• The agent has exactly one external action surface: run_python.
• Managed scripts declare third-party dependencies with PEP 723 inline metadata.
• The distributed package includes both uv_agent and uv_agent_runtime; managed scripts import helpers from uv_agent_runtime.
• Workspace rules, skills, and MCP declarations are progressively disclosed as context. MCP calls happen from Python runtime helpers, not direct model tools.
• Thread state, run logs, saved scripts, and attachments live under ~/.uv-agent/projects/<project-id>/.

Development

uv run pytest

Local debug state, screenshots, config, scripts, runs, and thread data belong in .uv-agent/ and should stay out of git.
