recode

recode is a lightweight, open-source coding agent you run from your terminal. It reads and edits files in your current project directory, using an LLM (via smolagents) to reason about the task and act through a small set of tools.

Think of it as a minimal, hackable alternative to tools like Cursor's agent mode — built to be understood, not just used.

Features

• Read & write files in your project directly from natural language instructions
• Persistent memory — the agent can remember facts across a session
• Sandboxed by design — the agent can only read/write inside the directory you run it from, never outside of it
• Runs anywhere — install once, use it in any project folder
• Built on smolagents' CodeAgent, meaning the LLM reasons by writing and executing real Python code, not by producing brittle JSON blobs

Installation

recode is distributed via GitHub and installed with pipx, which keeps it isolated while making it available as a global command.

# install pipx if you don't have it
brew install pipx
pipx ensurepath

# install recode
pipx install git+https://github.com/arobaseSuulei/recode-ai.git

Once installed, the recode command is available in any terminal, from any directory.

Configuration

recode needs an OpenAI API key to function. It reads it from the OPENAI_API_KEY environment variable — your key is never stored, bundled, or transmitted anywhere by this project.

export OPENAI_API_KEY=your_key_here

Add this line to your shell profile (~/.zshrc, ~/.bashrc, etc.) to avoid retyping it every session.

Usage

Navigate to the project you want the agent to work on, then run:

cd ~/my-project
recode

You'll get an interactive prompt:

-- Recode.ai, What are we going to build chief --
> add docstrings to every function in utils.py

The agent will:

1. Read the relevant file(s)
2. Reason about the change needed
3. Write the updated content back to disk
4. Report back what it did

Type exit or quit to leave the session.

Example

> create a function that subtracts two numbers and save it in math_utils.py

> read main.py and add a comment on every line

How it works

recode follows the ReAct pattern (Reasoning + Acting), the same loop used by most modern coding agents:

Thought → Action → Observation → Thought → Action → ... → Final Answer

Instead of asking the LLM to produce JSON instructions, recode uses smolagents' Code Agent approach: the model writes real, executable Python code to call tools, which tends to be more reliable and expressive than JSON-based tool calling.

Available tools

All file operations are restricted to the directory you launched recode from — the agent cannot read or write anywhere else on your system.

Safety notes

• recode can overwrite files without asking for confirmation. Use it inside a git repository, and commit your work before running the agent on real code, so you can always roll back with git checkout.
• Never commit your .env file or API keys to version control.
