Practical overview
When it fits
Use it for learning or prototyping command-line workflows that rely on bash and file read/write operations, or to examine a compact agent implementation.
Who it is for
- Developers learning how function-calling agent loops work.
- Python users who want a compact command-line starting point for local shell and file tasks.
Documented uses
- Ask an agent to inspect the current directory or list files matching a pattern.
- Read existing files or create and write new files from a natural-language instruction.
- Combine shell and file operations, such as finding Python files and counting their lines.
- Study or adapt a minimal model/tool interaction loop.
Requirements & limits
The project is a public GitHub repository with an MIT license. Its README documents local Python setup and an OpenAI API key; it does not document pricing or a hosted service.
- The built-in capabilities are bash execution, file reading, and file writing.
- The agent loop uses OpenAI function calling and can repeat model requests after tool results.
- The README documents setup with pip and environment variables, plus examples for macOS/Linux and Windows shells.
- The repository points readers interested in MCP and fetching tools in a more modern way to the separate nanoMCP project.
- The README describes handling malformed JSON arguments and unknown tool names by returning explicit tool errors to the model.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Install and configure Nanoagent
Prepare the documented Python project and OpenAI environment settings for the command-line examples.
Before you start
- Python and pip, as implied by the documented pip and python commands.
- Repository files, including requirements.txt and agent.py.
- An OpenAI API key set as OPENAI_API_KEY.
Steps
Install dependencies with pip install -r requirements.txt.
Set OPENAI_API_KEY in the shell environment.
Optionally set OPENAI_BASE_URL and OPENAI_MODEL; the README gives examples for macOS/Linux, PowerShell, and Windows CMD.
Expected outcome
The README's documented environment setup is in place for proceeding to its command-line examples.
Guide limitations
- This covers installation and environment configuration, not execution or successful setup verification.
- The README's command-line examples are the next documented stage; this guide does not claim they have been run.
