4,086 boosters — open source, verified from GitHub, ready to install
skill-installer automates the discovery and installation of Codex skills from curated repositories and GitHub sources, streamlining the setup process for developers building AI-assisted coding workflows.
This booster integrates Figma's MCP server into Claude Code to automatically fetch design context, screenshots, and variables, then translate Figma designs into production code. Developers working on design-to-code workflows benefit significantly from automated design asset retrieval and code generation.
A meta-guide that helps users create or update specialized skills to extend Codex's capabilities with domain-specific knowledge and workflows. Developers and AI agents building custom extensions benefit from this structured approach to skill development.
Playwright Interactive enables fast iterative UI debugging by keeping browser and Electron instances alive in a persistent js_repl session, allowing developers to test and refine UI interactions without repeated restarts.
This MCP server enables users to search and discover Agent Skills from the skills.sh registry, helping developers find and integrate pre-built automation capabilities into their AI agents.
Promptfoo is an LLM evaluation and testing toolkit that helps developers systematically test, benchmark, and validate prompt performance across different models and scenarios. It's essential for teams building LLM applications who need rigorous quality assurance and prompt optimization.
1. add a ts file to , the plugin api doc is in . 2. Add to to the part.
Automates Outlook Calendar operations like creating events, managing attendees, and scheduling meetings through Rube MCP integration. Useful for developers building agentic systems that need programmatic calendar control.

Automates the creation of pull requests from staged Git changes with auto-generated commit messages, helping developers quickly submit code changes without manual PR setup. Useful for Rust and search-engine projects on Claude Code.
[ULTRAQA ACTIVATED - AUTONOMOUS QA CYCLING] You are now in ULTRAQA mode - an autonomous QA cycling workflow that runs until your quality goal is met. Parse the goal from arguments. Supported formats:
This skill delegates to the formula, which lives at across all Gas Town rigs (gastown, beads, etc.). This rig (gastown/crew/max) is responsible for steveyegge/gastown only.
"name": "figma-developer-mcp", "mcpName": "io.github.GLips/Figma-Context-MCP", "description": "Give your coding agent access to your Figma data. Implement designs in any framework in one-shot.",
A performance optimization skill that identifies and fixes loading speed, rendering, animations, images, and bundle size issues to create faster, smoother user experiences. Developers building web applications benefit from automated performance diagnostics and improvements.
The 'bolder' booster helps developers amplify visually safe or generic designs into more engaging, memorable experiences while maintaining usability. Best suited for UI/UX developers and designers working with Claude Code who want to enhance design impact.
Heuristic scoring (no AI key configured).
Delight is a skill booster that helps developers add joyful, personality-driven touches to interfaces—transforming functional designs into memorable user experiences. It benefits product teams, UX-focused developers, and anyone building customer-facing applications.
A skill that helps developers create distinctive, production-grade frontend interfaces with polished aesthetics and creative design choices, avoiding generic AI-generated outputs. Ideal for developers building web components, pages, and applications who want professional design quality.
A skill booster that helps developers design and improve onboarding flows, empty states, and first-time user experiences to accelerate user adoption and value realization. Ideal for product teams and developers building user-facing applications.
The 'harden' booster helps developers make their interfaces production-ready by systematically addressing error handling, internationalization, text overflow, and edge cases. It's ideal for teams building robust web applications that need to handle real-world usage scenarios.
Distill helps developers simplify complex designs by stripping away unnecessary elements to reveal core functionality and clarity. Useful for engineers and designers iterating on features or refactoring existing components.
An audit skill that systematically evaluates interface quality across accessibility, performance, theming, and responsive design, generating prioritized reports with severity ratings and actionable recommendations. Ideal for developers and QA teams seeking to identify and document UI/UX issues before fixes are implemented.
A skill booster that helps developers redesign features to match their design system standards and ensure visual consistency across their codebase. Ideal for teams maintaining design systems or refactoring existing UIs.
A skill booster that adds strategic color to monochromatic UI features to improve visual engagement and expressiveness. Useful for developers and designers looking to enhance interface aesthetics within Claude Code environments.
