Skill UI

Enables Claude to examine EXPLAIN plans, spot slow queries or missing indexes, and deliver concrete optimization steps—ideal for improving database query speed and resource usage when performance issues arise.

Enables Claude to analyze request and data throughput, detect bottlenecks, and suggest scaling strategies via the throughput-analyzer plugin when performance or capacity optimization is requested.

Automate Apify web scraping Actors inside Claude Code to run crawlers synchronously or asynchronously, manage datasets, inspect logs, create reusable tasks, and pull structured results without leaving your workflow.

Artifacts Builder scaffolds Claude.ai-ready React+TypeScript projects with Tailwind/shadcn/ui, automating init and Parcel bundling into a shareable single HTML artifact for complex UI experiences.

A comprehensive template for developing modern, full-stack applications. This guide covers architecture overview, file structure, and best-practice code patterns for advanced technology stacks including Next.js, FastAPI, Supabase, and structured AI integration using Claude API. It serves as a robust blueprint for professional development teams.

This skill enables Claude to generate production-ready CI/CD pipeline configurations for major platforms, including GitHub Actions, GitLab CI, and Jenkins. It automates the entire software development lifecycle, supporting best practices for testing, building, security scanning, and multi-environment deployment. Use this when setting up automated software delivery workflows.

Analyzes a codebase to surface targeted Claude Code automations—hooks, subagents, skills, plugins, and MCP servers—so users know which extensions to add for workflows, testing, docs, or infrastructure.

This skill provides comprehensive guidance on leveraging d3.js (Data-Driven Documents) to create sophisticated, interactive, and publication-quality data visualizations. It covers core concepts like data binding, implementing various chart types (network graphs, geo-maps, etc.), handling complex transitions, and ensuring responsiveness across modern JavaScript frameworks (React, Vue, Vanilla JS). Learn the standard workflow for scale definition, axis creation, and drawing custom visual elements with fine-grained control.

Diagnose and fix Claude in Chrome MCP extension connectivity hiccups on macOS by toggling native messaging hosts, inspecting sockets, and running the provided toggle script whenever Claude Code CLI or Claude.app Cowork tools report “Browser extension is not connected” or behave erratically.

Audits and improves CLAUDE.md files across repositories by discovering every relevant file, scoring its sections, reporting quality issues, and preparing targeted additions before any write actions.

Claudeception continuously monitors work sessions, looking for reusable insights—debugging tricks, tool integrations, and workflow optimizations—and codifies them into new Claude Code skills so teams retain non-obvious knowledge for future tasks.

Guides how to author Claude Code slash commands using Markdown prompts, YAML frontmatter, dynamic arguments, Bash execution, and best-practice organization for reusable workflows and interactive automation.
