Spec-driven development for AI coding assistants

An open-source tool for generating detailed API specifications from natural language descriptions and existing codebases. Produces OpenAPI-compatible specs automatically, streamlines API documentation workflows, and helps teams maintain consistent, up-to-date API contracts across services. Reduces the manual effort of writing and maintaining API specs by inferring endpoints, schemas, and parameters from your actual code.

Open standard for guiding AI coding agents at the repository level

AGENTS.md is an open standard format adopted by 60,000+ open-source projects for providing AI coding agents with repository-level instructions. With 20,000+ GitHub stars, it has been adopted by GitHub Copilot, OpenAI Codex, Google Gemini CLI, and multiple IDEs as the de facto way to communicate project context and coding conventions to AI agents.

Twelve-lesson curriculum for building AI coding agents from scratch

Learn Claude Code is a comprehensive educational framework with 12 structured lessons teaching AI coding agent construction from first principles. With over 46,000 GitHub stars and 7,000 forks, it provides complete runnable Python implementations progressing from a 50-line bash agent to a 550-line skills agent with modular extensibility and subagent orchestration.

Up-to-date docs for AI code editors via MCP

Context7 is an MCP server developed by Upstash that injects up-to-date, version-specific documentation directly into AI code editors and coding assistants. By typing 'use context7' in prompts, developers get accurate library documentation instead of hallucinated or outdated API references. It pulls from official source documentation and serves it through the Model Context Protocol, solving the common problem of LLMs generating code with incorrect or nonexistent API calls.

Curated collection of agent skills and capabilities

An opinionated project scaffolding tool that generates AI-ready codebases with pre-configured CLAUDE.md files, git hooks, and CI/CD templates. Ensures new projects follow best practices for AI-assisted development from day one, including structured prompts, context files, and workflow configurations that help AI coding agents understand and navigate the codebase effectively.

Toolkit for spec-driven development with AI

GitHub's official toolkit for spec-driven development. Write specifications in natural language and let AI coding agents implement them with structure, consistency, and traceability. Bridges the gap between product requirements and AI-generated code by providing a standardized format that agents can follow reliably across complex projects.

Markdown with JSX components

AI-native terminal emulator that combines shell functionality with built-in LLM assistance. Ask questions about commands, generate scripts, and debug errors without leaving your terminal session. Integrates with your existing shell configuration and supports multiple AI providers, bridging the gap between traditional command-line workflows and AI-powered development assistance.

Focuses on developer control with transparent reasoning, approval workflows, and customizable safety boundaries. Designed for professional developers who want AI assistance with clear guardrails and the ability to review and approve every change before it's applied.

API design and documentation standard

Industry-standard specification for defining RESTful APIs with a comprehensive ecosystem of tools. OpenAPI Specification (formerly Swagger) describes endpoints, parameters, responses, and authentication in YAML/JSON format. Swagger UI generates interactive API documentation, Swagger Editor provides a visual spec editor, and Swagger Codegen generates server stubs and client SDKs in 40+ languages. The foundation of API-first development workflows used by millions of developers worldwide.

Beautiful, personalized API docs

Developer hub platform for creating interactive API documentation with try-it-now API explorer, auto-generated references from OpenAPI specs, custom landing pages, changelog, guides, and usage analytics. Features personalized docs that show API keys and example responses based on the logged-in user. Tracks which endpoints developers actually use. Integrates with GitHub for syncing docs from repos. Used by companies like Twilio and Shopify for their developer portals.

Knowledge management for teams

Modern documentation platform that combines a WYSIWYG editor with Git-backed version control for technical documentation, API references, and knowledge bases. Features real-time collaboration, OpenAPI/Swagger integration for auto-generated API docs, custom domains, visitor authentication, and AI-powered search.
