Harnessclaw is an Electron desktop application for configuring AI agents, chatting with them, browsing skills through ClawHub, and reviewing session history from a single interface. It is aimed at users who want a visual control surface instead of managing each agent workflow separately. The current documentation focuses on installing dependencies and building from source with Node.js and Yarn, with build targets for macOS and Windows.

AWS Skills packages Claude Code plugins for CDK and SST infrastructure, serverless architecture, cost and operations work, and Bedrock AgentCore deployment. The plugins combine focused instructions, validation scripts, references, and AWS MCP integrations for documentation, pricing, Cost Explorer, and CloudWatch. The shared aws-common plugin is a dependency when components are installed individually.

Nomi is a local-first desktop workspace for taking an AI video from an idea to an exported MP4. It connects script writing, shot planning, image and video generation, reusable assets, and timeline editing in one project. A 3D staging area lets creators position characters and cameras, lock character identity, and define camera paths so visual intent can be passed to generation models more precisely. Users bring their own model endpoint and API key, with desktop builds for macOS and Windows; generation quality, availability, and cost depend on the connected services.

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.

TestMu AI Agent Skills add framework-specific testing guidance to coding assistants such as Claude Code, Copilot, Cursor, and Gemini CLI. The repository covers major automation stacks including Selenium, Appium, Playwright, and Cypress across numerous languages, with skills installable individually. Using the hosted testing platform requires Node.js plus a TestMu AI account, username, and access key.

software-design-philosophy is a reusable agent skill based on John Ousterhout's A Philosophy of Software Design. It gives coding assistants a design framework for code reviews, architecture discussions, API design, module decomposition, refactoring, naming, comments, and error-handling strategy. Users can install it in Claude Code, Codex, or compatible skill managers and invoke it alongside an existing project. The repository supplies guidance for making software-design decisions; it is not a standalone static analyzer or development application.

FaceGate adds per-application locking to macOS and can authenticate with local face recognition, Touch ID, or a password. It supports liveness challenges, multiple enrolled faces, external cameras, and configurable unlock sessions for individual apps, with recognition and credential handling kept on the Mac. The app is not Apple-notarized, so manual installation requires removing its Gatekeeper quarantine attribute.

Social Media Skills provides a coordinated set of workflows for audience context, positioning, editorial calendars, platform strategy, post and thread writing, carousel scripts, visual-platform captions, repurposing, hooks, and performance analysis. It covers LinkedIn, X, Threads, Bluesky, Facebook, Instagram, TikTok, and Pinterest use cases, and skills can be installed together or selectively. With BlackTwist MCP it can publish, schedule, and fetch analytics; without it, the workflows remain advisory.

Dream-to-Video Skill converts a written dream into a cinematic prompt, places it in a local SQLite and JSONL queue, and drives Jimeng through Playwright and Chromium. The worker handles login, submission, progress monitoring, downloads, and an Elliptic Shatter edge effect, producing both original and processed video files. Setup requires Python 3.10+, Chromium, an API key for a supported language model, the repository toolchain, and a one-time QR-code login to Jimeng.

SONE gives Linux users a native desktop client for browsing their TIDAL library, managing playback, and sending lossless audio directly to an ALSA device or DAC at source rates up to 24-bit/192kHz. It also includes synced lyrics, a floating mini player, and scrobbling integrations. An active TIDAL subscription is required, and the client streams music only rather than supporting offline downloads.

Gemini Desktop places Google Gemini in a dedicated app with multiple conversation tabs, a global-hotkey Quick Chat window, tray controls, always-on-top mode, and response notifications. Releases are available for Windows, macOS, and Linux, with no application telemetry; authentication remains handled by Google. Development has been on hiatus since July 2026, so existing builds remain available but new fixes are not planned and issues or pull requests may go unanswered.

Skill Doctor scans project, global, and system skill roots to show what is installed, which definition wins, where names or triggers collide, and where risky patterns appear. It offers a local browser UI, CLI reports, and immutable scan history while binding to localhost by default. Static analysis works locally, with optional model-assisted analysis available through a configured compatible endpoint.

This repository offers a set of agent skills for improving visual parts of a product, including animation, typography, layout, and color. It can be installed with `npx skills add jakubkrehel/skills` and then used from an agent host that supports skills. The available project description does not enumerate the individual skills, workflows, or framework requirements, so it is best treated as a collection to inspect and invoke selectively for interface-polish work.

This marketing skill collection packages repeatable workflows for A/B testing, analytics tracking, competitor pages, content strategy, copy editing, landing-page conversion, email sequences, and SEO audits. It is a fork of coreyhaines31/marketingskills that adds prebuilt `.skill` files for easier installation in Claude Code and other Agent Skills-compatible tools.

Greptile Skills provides workflows for checking unresolved review comments and status failures, running a Greptile CLI review on the current checkout, and repeatedly reviewing and fixing a change. The skills can detect GitHub, GitLab, or Perforce from the environment, but you must install and authenticate the matching gh, glab, p4, or Greptile CLI first.

afm runs Apple's on-device Foundation Model or Hugging Face MLX models on a Mac and exposes them through an OpenAI-compatible server, a web chat interface, single prompts, or shell pipelines. Its gateway mode can also discover and proxy local backends such as Ollama, LM Studio, and Jan, with separate OCR and embedding endpoints available. The main platform requirements are macOS 26 or later, Apple Silicon, and enabled Apple Intelligence.

Robotics Agent Skills supplies focused guidance for ROS1, ROS2, testing, bringup, perception, design patterns, containers, and security. Loading the relevant SKILL.md files helps agents account for issues such as QoS compatibility, lifecycle nodes, bounded callbacks, health checks, and safe shutdown rather than generating syntax-only ROS code. The skills can be copied into Claude Code, Cursor, or custom agent frameworks.

YouTube Comment Suite is a cross-platform JavaFX desktop application that aggregates comments from multiple YouTube videos, playlists, and channels for archiving, search, and activity analysis. It filters by video, type, username, keyword, length, or date, summarizes publishing and commenter activity, and saves thumbnails and user profiles for offline reference. Release packages expect Java 8; Java 11 and later require the workaround documented in the project wiki.
