Claude Skills
The open format is called Agent Skills and works in Claude Code, Codex, Cursor and other agents — most people know it as Claude Skills.
Every Agent Skill we could find on GitHub, deduplicated by content. 79 600 files from 1 763 authors, of which 61 947 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.
Use this skill when reviewing or fixing SwiftUI performance issues, including unnecessary invalidation, unstable identity, broad state dependencies, expensive body work, heavy rows, scrolling hitches, layout/drawing cost, or async lifecycle work. Do not use it for general SwiftUI syntax, styling, UIKit-only performance, or generic profiling unless SwiftUI update behavior is central.
Use this skill when choosing, running, or interpreting iOS performance profiling workflows, including Instruments traces, signposts, XCTest metrics, MetricKit, Xcode Organizer, hangs, hitches, CPU, allocations, memory graphs, disk I/O, networking, power, or production performance signals. Do not use it as the deep domain skill for launch, SwiftUI, concurrency, perceived performance, or runtime issues unless the task is specifically about measurement, tool selection, trace interpretation, or verification.
Use this skill for product-level iOS responsiveness and loading/feedback flows, including perceived latency, time to first feedback, progressive rendering, loading states, skeletons, placeholders, optimistic updates, rollback behavior, high-stakes actions, UI continuity, and responsiveness validation. Do not use it for low-level CPU, memory, rendering, Swift Concurrency, or launch-performance diagnostics unless the task is about user-perceived speed.
Controls interactive terminal sessions for running long-lived processes, servers, REPLs, debuggers, and TUI programs without blocking. Use when you need to run dev servers (npm run dev), debuggers (pdb, gdb), REPLs (python, node), databases (psql, mysql), SSH sessions, or editors (vim, nano) — any interactive or blocking program.
>- Translates English into idiomatic, translationese-free Chinese, optionally as an English-Chinese bilingual version pairing each source paragraph with its translation. Use when the user wants to 翻译成中文 / 英译汉, 去翻译腔/润色译文 (remove translationese, polish a draft), or produce a 中英对照/英中对照 bilingual rendering. Not for Chinese-to-English, pure Chinese writing polish, or single-word lookups.
Run trace-mcp security, quality-gate, and antipattern checks before committing or opening a PR. Activate when the agent is about to create a commit or pull request in a project indexed by trace-mcp.
Use trace-mcp tools for code navigation, impact analysis, and framework-aware queries instead of Read/Grep/Glob/Bash. Activate whenever the agent needs to explore, understand, or modify a codebase that has trace-mcp indexed.
Use trace-mcp apply_codemod for any bulk mechanical change instead of repeated Edit calls. Activate whenever the same edit pattern would be applied 2+ times, across one file or many.
Safe refactoring workflow using trace-mcp — assess risk, find candidates, check impact, and rename symbols across all files without missing import sites or cross-file references.
Set up, repair, or verify the local AI short-video environment: video-use, FFmpeg, the Source Han Sans TW subtitle font, ElevenLabs credentials, and optional HyperFrames skills. Use whenever a user asks to install, configure, fix, reconnect, or check this editing environment. Do not use for Premiere or CapCut help, or to edit/transcribe media; hand those requests to the editing workflow after setup is verified.
Edit a user-supplied video into a vertical Reel, Short, TikTok, video diary short, or an approved eight-step AI short-video workflow. Use when the user provides or points to media and asks to transcribe, cut, subtitle, preview, or export a vertical short. Do not use for environment-only setup or generic Premiere Pro or CapCut help.
>- Guidance for TypeScript monorepos with mixed package managers. Use when codebase has inherited package manager and a workspace root.
Use the Unoplat Code Confluence CLI to run the local app, configure providers, add repositories, and generate AGENTS.md artifacts with automatic PR publication. Trigger when users mention Unoplat, Code Confluence, repository setup, AGENTS.md generation, or agent-md workflows.
>- Author and review one evidence-based Mermaid architecture-beta diagram using Mermaid's official Architecture Diagram syntax and the packaged Mermaid CLI.
