Gausian Native Editor is a cross-platform native video editor for local AI-video workflows. It provides GPU-accelerated preview, asset management, timeline trimming, proxy generation, project persistence, and exports for FCPXML, FCP7 XML, EDL, and JSON. It can automatically import output from a locally running ComfyUI instance, while macOS can optionally open that instance in an embedded WebView. The project is primarily run from source, requires Rust and FFmpeg, uses GStreamer for some proxy and decoding paths, and does not support remote ComfyUI servers.

Openfoot Manager is an open-source football management simulation where players shape squads, assign roles, negotiate transfers and contracts, plan training and staff work, scout talent, and follow text-based matches. Save data is stored locally in SQLite. The game is still in early active development, and the documented setup currently focuses on users who can install the Rust, Node, and Tauri toolchains and run it from source.

manim_skill provides separate Agent Skills for Manim Community Edition and ManimGL, with tested examples and guidance for scenes, animations, objects, text and formulas, cameras, and 3D rendering. Coding assistants can load the relevant framework knowledge while working on educational or mathematical animation projects. The two Manim variants are incompatible, and typical use also requires Python, FFmpeg, and LaTeX.

Describe the game you want and start with the director skill; it routes the work across gameplay, graphics, UI, audio, debugging, and release checks. The package includes a Vite and TypeScript scaffold, deterministic test hooks, a seeded random generator, and Playwright templates for browser, visual, and bot testing. Core game work runs without paid API keys, while optional external asset generation requires provider credentials.

Heimer is a desktop editor for mind maps and other lightweight diagrams on Linux and Windows. It lets you add node text and edge labels, arrange the canvas with a grid and automatic layout, and work with autosave, undo, redo, and zoom controls. Projects are stored in an XML-based ALZ format and can be exported as PNG or SVG, with packaged downloads available for common Linux formats and Windows.

RClone Manager adds a desktop interface to Rclone remote storage. Users can browse and preview files, copy, move, rename, or delete them, control mounts, and monitor transfers and bandwidth from an integrated file manager. It can also serve remote content over WebDAV, SFTP, HTTP, or FTP, with a separate headless web mode for VPS and NAS deployments. The underlying cloud or storage accounts still need to be configured as Rclone remotes.

Tauri Controls supplies minimize, maximize, and close controls styled for Windows, macOS, or GNOME in Tauri 2 desktop applications. It can detect the current operating system automatically or let developers select a platform style, with packages for React, Solid, Vue, and Svelte projects. Window actions are handled through Tauri’s JavaScript and TypeScript APIs. The controls are HTML elements designed to resemble native system components rather than wrappers around native UI APIs, and integration requires the corresponding Tauri window and OS plugins plus peer dependencies.

UnlimCloud Desktop App is an unofficial Windows client for a storage service that uses a Telegram ID as the account identifier. Users can upload, download, and organize files and folders, with a gallery for pictures and videos. It currently targets Windows; macOS and Linux releases are described as future plans rather than available downloads.

SkillSpec audits a skill for discovery risk, context load, buried obligations, undeclared dependencies, and missing proof. It can then import the prose instructions into a neighboring skill.spec.yml contract with explicit routes, forbidden actions, checks, tests, and evidence requirements, while leaving an alignment summary after execution. It is a CLI and contract layer rather than a new agent runtime, orchestration platform, or security boundary.

Swifty is an offline-first password manager for macOS, Windows, and Linux. It keeps login credentials, credit-card details, secure notes, generated passwords, and time-based one-time codes in an encrypted file on the local machine, unlocking them with a master password. Backups can move the vault between computers, while Google Drive synchronization is optional for users who want it. Packaged releases are available, or the desktop app can be built from source.

Use SkillPack to combine skills from GitHub, URLs, or local folders with prompts, policies, personas, and optional scheduled jobs. It produces a lightweight archive that teammates can unpack and launch into a local browser interface, with optional Slack or Telegram access. The runtime keeps team data on the host machine but requires Node.js 22.19.0 or newer and an LLM API key.

Hermes Agent CN Desktop adds a native desktop shell around the Chinese community edition of Hermes Agent. It provides chat, attachments, Skills, Memory, scheduled tasks, model-provider setup, and runtime diagnostics, while bundled releases can initialize and manage an isolated Hermes-CN-Core installation. Users configure either a cloud API key or a local model endpoint; the main agent runtime and Dashboard remain in the separate core repository.

Whalebird presents Fediverse timelines in a single-column, Slack-like desktop interface with streaming updates, notifications, and multiple-account management. It works with Mastodon, Pleroma, Friendica, Firefish, GoToSocial, Pixelfed, and several unofficially supported servers. On Windows, the signed Store release is recommended because standalone binaries are not code-signed.

Install this collection to give compatible coding agents reusable guidance for Kotlin projects. Each skill packages its own instructions, scripts, and resources, and can be added through the Skills CLI, Claude Code or Codex marketplaces, or copied into a project manually. The current catalog focuses mainly on backend development and tooling rather than providing a standalone application.

GitLight combines GitHub and GitLab notifications in a single kanban-style inbox instead of making developers check each platform separately. It can deliver push notifications, show detailed event information, and filter activity by repository, organization, pull request, issue, commit, and other project context. Both services can be monitored at the same time, which is useful for teams whose work spans multiple hosting providers. The free open-source client is available for macOS, Windows, Linux, and the browser, with a Homebrew installation option on macOS.

Flow-Like is a local-first visual workflow platform for combining data, APIs, files, AI models, and user interfaces in one project. Users can build private RAG assistants, data pipelines, scheduled agent automations, or internal and customer-facing apps with typed connections, execution tracing, and built-in storage. Custom nodes can run as sandboxed WebAssembly, and projects can be used online, on desktop, or deployed to infrastructure the user controls.

ByteChef combines AI-agent orchestration, application connectors, and workflow automation in a visual environment. Users configure models and tools, then connect them with conditions, loops, parallel branches, schedules, webhooks, and other triggers; connectors can also serve as agent or MCP tools. Docker Compose runs the application with PostgreSQL for self-hosting. The community edition includes the core editor, agents, workflows, and connectors, while workflows exposed as APIs and Git-native management are reserved for the enterprise edition.

These skills guide an agent through builds, signing, TestFlight distribution, metadata and localization, submissions, Apple Ads, and related asc CLI workflows. They also document command selection, authentication, pagination, and JSON-first automation. The pack is community maintained, unofficial, and not affiliated with Apple.
