Overview
zcf (Zero-Config Code Flow) is a lightweight tool for Claude Code and Codex that minimizes configuration to embed model-driven code flows into developer workflows. It chains model calls, prompt templates, and execution steps into reusable flows, enabling quick prototypes and automated code-driven tasks. zcf is suitable for developers building agentic code execution, automated testing flows, and CI integrations.
Key features
- Zero-config startup with sensible defaults and templates to reduce environment setup.
- Support for multiple model backends (e.g., Claude Code, Codex) with a plugin-based executor architecture.
- CLI-first design and scriptable flows for easy CI/CD integration and batch automation.
Use cases
- Rapid prototyping of model-driven code generation and execution in developer tooling.
- Embedding model capabilities into automation scripts or CI pipelines for tasks like data processing, code repair, and test generation.
- Educational demos to illustrate the loop between model outputs and code execution.
Technical highlights
- Implemented in TypeScript and designed for the Node.js ecosystem for easy integration.
- CLI-driven flow definitions and plugin architecture enable composable executors and data routing.
- Emphasizes observability and reproducibility with flow logs, templates and execution traces.
