Agent Scripts

Agent Scripts is a collection of reusable scripts and utilities for AI-powered coding agents, maintained by Peter Steinberger (@steipete). Shared across his open-source GitHub repositories (including Poltergeist and Arena), these scripts provide a common foundation for automating workflows—such as file watching, build triggering, and command composition—using shell and other scripting languages. Targeted at developers and engineers working with agentic tools like Claude Code or custom LLM pipelines, the project emphasizes simplicity, composability, and real-world experience. The scripts are MIT-licensed and designed to be forked, remixed, and integrated into any agent workflow. They cover patterns like watching for file changes, triggering builds, and orchestrating multi-step tasks. The collection is tightly integrated with Steinberger's other open-source projects: Poltergeist (a universal build watcher) and Arena (a real-time collaborative coding tool). While not a commercial product, it serves as both a learning resource for newcomers and a practical toolkit for seasoned agentic engineers. Steinberger shares his agentic engineering philosophy in blog posts like "Just Talk To It" and "Shipping at Inference-Speed," giving insight into how these scripts are used in practice. As an open-source project, Agent Scripts benefits from community contributions and transparent development. Compared to full-featured agent platforms like LangChain or AutoGPT, Agent Scripts is deliberately minimalist: you get code, not abstractions. It's best for developers who prefer CLI tools and want to understand agent internals rather than relying on black-box frameworks.
