Description

GSD 2 is a process-oriented framework for using AI agents in software development workflows. It is designed to help developers and teams turn AI-assisted coding from one-off prompts into a more organized system of planning, execution, and validation. The framework emphasizes the importance of clear specifications, shared context, review steps, and structured artifacts that guide how agents complete work. By creating a stronger process around AI coding, GSD 2 helps teams reduce confusion, improve handoffs, and maintain alignment between requirements and implementation. It supports the idea that successful AI development requires more than a powerful model; it also needs governance, feedback, and repeatable workflows. Developers can use GSD 2 to coordinate tasks, capture decisions, and review outputs before they become part of a production codebase. The framework is useful for managing the risks of AI-generated work, including specification drift, excessive trust in generated artifacts, and weak validation practices. It encourages human review as a core part of the development loop rather than treating AI output as automatically correct. GSD 2 helps teams use AI coding agents with more confidence, consistency, and engineering discipline.

Description

Pi is a streamlined terminal coding environment designed to seamlessly integrate with developer workflows rather than requiring developers to conform to its structure. It comes equipped with robust default settings while maintaining a compact size and extensive customization options, allowing users to enhance Pi through various extensions, skills, prompt templates, themes, and shareable packages sourced from npm or git. When a team requires a specific command, tool, provider, workflow, or UI modification, they can simply instruct Pi to create it, make adjustments on the fly, reload, and continue their work without interruption. Pi is versatile, offering support for interactive, print/JSON, RPC, and SDK modes, which enables it to function as a comprehensive terminal UI, a scriptable command interface, a JSON event stream, or an easily embeddable agent harness. It is compatible with over 15 providers and numerous models, including options like Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, Kimi For Coding, MiniMax, OpenRouter, Ollama, and other services, facilitating mid-session model switching to enhance flexibility and user experience. This adaptability makes Pi an invaluable tool for developers looking to tailor their coding environment to meet their specific needs.
