SuperpowersSuperpowers is an MIT-licensed agentic skills framework and software-development methodology for coding agents. It packages repeatable workflows such as brainstorming, specs, implementation plans, TDD execution, subagent-driven development, and structured review so teams can move from ad hoc prompting to disciplined agent-assisted software delivery.Agent SkillsAgent Skills is the open SKILL.md folder specification for packaging reusable instructions, scripts, references, and assets that compatible AI agents load through progressive disclosure. Originally developed by Anthropic and released as an open standard, it defines the portable format itself—not an example library, marketplace, or hosted agent product.Agentic WorkflowA template system that bootstraps AI-driven development workflows for your projects. Provides structured workflows, templates, and configurations for integrating AI agents into your development process. Reduces setup time by giving teams a proven starting point for organizing AI-assisted coding, task management, and quality assurance in new and existing repositories.Anthropic Agent SkillsAnthropic Agent Skills is Anthropic's official reference repo and Claude Code plugin marketplace for reusable Skill folders. It packages example SKILL.md workflows, document skills, a Claude API skill, templates, and the Agent Skills spec so teams can turn repeatable instructions, scripts, and resources into on-demand Claude capabilities instead of copying prompts across sessions.ArchifyArchify is an open-source AI agent skill with 37,000+ GitHub stars that compiles typed JSON intermediate representations into interactive, animated system architecture diagrams with motion and visual delta diffs for Claude Code and Cursor.Awesome Agent SkillsAwesome Agent Skills is VoltAgent's MIT-licensed list of agent skills from official teams and the community for Claude Code, Codex, Gemini CLI, and Cursor.Awesome Claude CodeOfficial Anthropic-curated list of Claude Code tips, CLAUDE.md templates, hooks, MCP servers, and community tools.
