Compose Performance Skills teaches a coding agent how to measure, diagnose, fix, and verify Jetpack Compose performance problems. The library covers stability, recomposition, lazy layouts, custom modifiers, side effects, baseline profiles, R8, and related tooling, with references back to primary sources and version-pinned APIs. It is aimed at Android Compose rather than general onboarding, and Compose Multiplatform targets have not been specifically validated.

Skill Optimizer separates the agent-skill lifecycle into three workflows. skill-miner examines agent history, memories, archives, and repeated tasks for evidence-backed candidates; skill-personalizer adapts skills to a user's phrasing, tools, paths, and verification habits; skill-generalizer removes private context for public distribution. It also audits undertriggering, noisy activation, unnecessary questions, conflicts, and token costs. A deterministic scanner supports session data from Codex, Claude Code, Gemini, and exported transcripts.

flutter-ai-rules packages Flutter, Dart, state-management, testing, and tool-specific guidance as Agent Skills and traditional rule files for environments such as Cursor and Windsurf. Copy or link only the skills and rules your project needs so the coding agent can load them contextually. The material is drawn from official documentation, which also means guidance from different packages may sometimes conflict.

Give an AI coding tool practical guidance for data races, isolation errors, flaky async tests, actor design, Sendable conformance, and concurrency performance. The skill is aimed at teams adopting Swift 6 strict concurrency and includes references for newer isolation and task semantics. It can be installed through skills.sh, as a Claude Code plugin, or manually in any tool that supports the Agent Skills format.

Video Podcast Maker turns a topic into a narrated video workflow: it researches the topic, drafts the script, tracks assets, produces voice-over and subtitles, mixes audio, and renders with Remotion for platforms such as YouTube, Bilibili, Xiaohongshu, Douyin, and WeChat Channels. Free sources can resolve automatically; paid image or video generation requires a quote and explicit approval, and the script still needs repeated human polishing.

Skills Manager brings GitHub skill catalogs and local folders into a three-column macOS app with search, tag filtering, Markdown previews, editing, installation, and removal. It can manage both Claude Code and Codex skill locations and supports multiple catalogs, but requires macOS 15 or later.

LyricsX searches multiple lyric sources and displays live lyrics on the macOS desktop or menu bar while supported music players run. Users can adjust typography and timing, double-click a line to seek, import or export lyric files, and convert Traditional and Simplified Chinese. Its LRCX format supports word timing and translations, but the project notes that no official LRCX editor is currently available.

Firecrawl CLI runs search, scraping, interactive browsing, mapping, crawling, and agent jobs from the terminal. Its setup commands can also install Firecrawl skills, workflow skills, and MCP configuration for Claude Code, Codex, Cursor, Windsurf, and other supported harnesses; authentication is required for service access, and anonymous telemetry can be disabled.

ArcDLP wraps yt-dlp in a desktop app for macOS, Windows, and Linux. Paste a media URL to inspect metadata, choose quality, download MP4 video, or extract MP3 audio; playlists can be filtered and queued in batches. The queue shows per-item progress and supports cancel, skip, and retry without one failure stopping the rest. Built-in browser sign-in supports authorized YouTube or Instagram content. Release packages bundle yt-dlp and ffmpeg, while site coverage and protected-content access still depend on yt-dlp and user permissions.

Minutes turns meetings, voice memos, and dictated thoughts into locally stored Markdown that AI tools can search directly. Record through the desktop app, import and query through the CLI, or expose meeting memory to Claude, Codex, Gemini CLI, and other clients through MCP. Live transcripts can also support assistance during a meeting. Because transcription and storage stay on the user's machine, the project suits people who want searchable conversation history without giving up ownership of recordings and notes.

Install MyKVM on Windows, macOS, or Linux machines, choose one computer as the server and another as the client, then arrange their screens to match your desk. Moving the pointer across a shared edge transfers keyboard and mouse control, while text and image clipboards synchronize in both directions. Devices can discover each other on the same LAN or connect by IP. The current release is an experimental trusted-network prototype without pairing codes or authenticated discovery, so its transport ports should never be exposed to public or untrusted networks.

Use an AI coding agent to review and improve web projects against Lighthouse guidance, Core Web Vitals patterns, WCAG 2.2 accessibility practices, SEO requirements, and modern browser standards. The skills work across major frameworks or plain HTML and can be invoked by topic, but this is an unofficial collection intended as structured engineering guidance rather than an official certification tool.

Pinkbin combines disk analysis, folder explanation, and cautious cleanup in a Windows desktop app. It scans NTFS volumes, highlights large directories in a tree and treemap, then sends directory metadata—not file contents—to a user-selected cloud model or Ollama for an explanation of what may be safe to remove. Deletions go to the system recycle bin by default. Dedicated cleanup scripts currently cover only WeChat for Windows and Conda, and prebuilt macOS or Linux releases are not yet provided.

Use openapi-to-skills to turn a local or remote OpenAPI specification into Markdown documentation organized for on-demand agent reading. It groups resources, operations, and schemas, with filters and custom templates for shaping the output. Specifications with external references need to be bundled before conversion.

Dopamine is a desktop audio player focused on making local music organization and listening straightforward. The current Electron-based version runs on Windows, Linux, and macOS, with several package options documented for Linux, including AUR, Snap, RPM, and Pacman builds. It is aimed at listeners who want a dedicated desktop player for organizing and playing their music across their main operating systems.

Rustman is a native desktop API client that uses a local Rust HTTP engine instead of a webview, avoiding browser CORS restrictions. It supports common authentication methods, environment variables, file uploads, WebSocket sessions, editable request and response bodies, and locally stored collections and history. The app needs no account and sends no telemetry, with builds for macOS, Windows, and Linux. Its pre- and post-request script interface exists, but the runner is still a work in progress.

Colanode combines team messaging, rich-text pages, structured databases, and file management in web and desktop clients that can connect to multiple servers and workspaces. Changes are written to local SQLite first and synchronized in the background, allowing continued work while offline and concurrent editing when teammates reconnect. Self-hosting requires Postgres, Redis, and a file storage backend. The hosted web client is currently described as an early preview and may still have browser compatibility issues.

VideoRAG is an open-source framework for retrieving and answering questions over long-form video, with the Vimo desktop interface for importing one or more videos and chatting about their contents. It also includes the LongerVideos benchmark and evaluation code for researchers working on long-context video understanding. Prebuilt Vimo downloads are still marked as coming soon, so current users generally need to start the Python backend and Electron frontend from source.
