About Smol developer
Smol developer is an open source Python project that scaffolds a codebase from a product spec and provides functions for embedding that developer agent in another application. It can be run from a cloned repository, imported with pip as smol_dev, or run as a local server using Agent Protocol.
In repo mode it generates code from a command-line prompt or markdown file, with options for model selection and debugging. Library use involves generating a coding plan, determining file paths, and generating code per file. The workflow expects human review, running the code, and updating the prompt to iterate.
Key features
- Scaffolds a codebase from a product spec prompt
- Installable Python library for embedding agent in apps
- Generates coding plan and file list from prompt
- Generates source code for each planned file
- Runs local API server via Agent Protocol
- Debugger script suggests changes based on full codebase
Best for: Developers who want to prototype apps from prompts or embed code scaffolding in a Python app.
Good for
- Available as cloned repo, importable library, and local API
- Supports iterative human review with prompt updates
- Open source repository
Watch out for
- Requires human to run, read, and correct generated code
- File path generation relies on OpenAI Function Calling API
- Does not bootstrap its own prompt from an existing codebase
