Startup Skill packages market research, customer discovery, competitor analysis, battle cards, positioning, financial projections, and validation experiments into agent workflows. It can run a full startup-design process for a new business idea or handle narrower competitive-intelligence and planning requests. The skills install as a Claude Code plugin or through clients that support the Agent Skills format.

SkVM profiles a model-and-agent-runtime combination, compiles a skill against those capabilities, and then evaluates and improves it through precompilation and runtime-optimization workflows. It is aimed at teams that need the same skill to behave across heterogeneous agents rather than tuning prompts by hand for each runtime. Provider configuration is required, and the bundled benchmark suite lives in a separate data submodule.

HoYo.Gacha is an unofficial Windows tool for managing multiple accounts and gacha records from Genshin Impact, Honkai: Star Rail, and Zenless Zone Zero. It reads Chromium disk cache data and contacts the relevant API without requiring a local proxy, then stores the results in a local database. UIGF and SRGF are supported for import and export, while CSV is export-only. Because the database contains all local accounts and history, it must be preserved when moving the application or migrating the operating system.

Claude_skills_zh-CN reorganizes and translates the Anthropic Skills repository for Chinese-speaking developers while preserving its original structure. It includes localized guidance and examples for documents, spreadsheets, visual design, frontend work, MCP development, and skill creation. Users can read the SKILL.md files to study the patterns, install them in compatible Claude environments, or use the collection as a reference when building internal skills.

Claude Plugins combines a searchable registry with separate CLIs for Claude Code plugins and cross-client agent skills. It resolves public GitHub sources, installs skills globally or per project, and supports clients such as Claude, Cursor, Codex, Gemini CLI, OpenCode, and others. Claude plugins require Claude Code 2.0.12 or later, while skill support depends on the target client.

Lynkr is a self-hosted LLM gateway for coding tools including Claude Code, Cursor, and Codex. After an interactive setup, users connect existing clients through a local endpoint or wrapper command, then route simple and complex work to different local or cloud models. It reduces unnecessary model traffic through tool-result compression, tool filtering, and semantic caching. The gateway requires Node.js 20+, while local configurations also need a running backend such as Ollama.

This skill equips Claude Code with current Solana patterns for wallet flows, transaction handling, React or Next.js dApps, Anchor or Pinocchio programs, typed client generation, local testing, and security reviews. It also includes compatibility tables, common-error fixes, and migration guidance, and installs through the skills CLI.

AI Hot Monitor is a hands-on teaching project built around a working trend-tracking application. Users define keywords, aggregate results from more than eight sources including Twitter, Bing, Hacker News, and Bilibili, then apply AI query expansion, authenticity checks, relevance scoring, and summaries. Results can be filtered and pushed through WebSockets or email, and the monitoring workflow is also packaged as an agent skill; the repository is primarily presented as a build-from-scratch course project rather than a hosted service.

ClearDisk is a macOS menu bar app for finding rebuildable data left by Xcode, package managers, Docker, and local projects. It explains each cache, assigns a risk level, and moves selected files to Trash rather than deleting them permanently. The current build requires macOS 14 or later on Apple Silicon, and downloaded releases are not notarized by Apple.

Claw Code Agent reimplements a Claude Code-style coding workflow in Python for OpenAI-compatible model servers. It provides a CLI, multi-turn chat, a local web interface, file and shell tools, sessions, permissions, plugins, and nested delegation while using only the Python standard library. Development is ongoing, and full MCP, hook, background-team, and platform parity is not yet complete.

DockAnchor prevents the macOS Dock from jumping between displays when the pointer reaches another screen edge. Users choose an anchor display, and the utility can move the Dock back automatically while running quietly in the background. Profiles can switch according to the connected monitor arrangement, and the app can launch at login with menu-bar controls. Processing stays local and only mouse movement is monitored, but accessibility permission is required for the core behavior.

color-expert is an installable skill for Claude Code, Codex, Cursor, Copilot, OpenCode, and other agents. A concise SKILL.md provides frequently needed facts, corrections, and practical guidance, while an index routes the agent to 144 deeper references on color spaces, APCA and WCAG accessibility, palettes, pigment mixing, historical theory, tools, papers, and transcripts. Trigger evaluations, realistic task prompts, and maintenance guidance help keep the collection organized. It is intended for explanations, color reviews, and implementation advice.

CrossDrop is an experimental, partial implementation of Google Quick Share for macOS, Linux, and iOS. It can exchange files, text, links, and Wi-Fi credentials with Android Quick Share or other CrossDrop devices, using PIN confirmation or QR pairing; on desktop it runs from the menu bar or tray and saves received files to a chosen download folder. The project is in an experimental continuation state, and the maintainer notes that official Quick Share and AirDrop compatibility may make it unnecessary for routine use.

Give coding agents versioned standards for languages, frameworks, and software delivery without replacing the tools your team already uses. The CLI initializes, syncs, and validates native assets for agents such as Cursor, Claude Code, Copilot, and Gemini, while an optional MCP server can load matched guidance at runtime and preserve project-specific overrides.

ScreenArc records a full display, window, or selected area and automatically follows mouse movement and clicks with smooth pan-and-zoom effects. Its timeline editor supports trimming, backgrounds, framing presets, webcam overlays, and exports up to 2K as MP4 or GIF, making it useful for tutorials and product demos. Builds are available for Windows, macOS, and Linux, but Linux currently requires X11 and the Windows and macOS packages are not code-signed.

ClawWork is a local-first desktop and PWA client that connects to the user's own OpenClaw installation. It runs multiple tasks in parallel with isolated sessions, keeps generated artifacts durable, and provides full-text search across tasks, messages, and files. Users can also schedule recurring runs, review usage and cost, and install multi-agent teams or skills from community registries. Builds are available for macOS, Windows, and Linux. The current product is optimized for OpenClaw; support for additional agent runtimes remains a future direction.

Power Design is a Claude Code skill that turns a short brief into either an HTML presentation or a responsive website. It first asks which format and brand to use, then can extract brand characteristics from a URL through Firecrawl or select from more than 72 bundled brand systems. Separate sets of 20 rules guide slide and web output. The resulting HTML opens in a browser and can be refined through conversation, making it useful when users want more deliberate structure and styling than a generic AI template.

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.
