Skills can be selected and installed with `npx skills add google/skills`; the repository also bundles plugins and MCP servers for agent harnesses including Claude Code, Codex, and Antigravity CLI. The repository accepts bug reports and contributions, and its skills are distributed under the Apache 2.0 license.

Angular is an open-source web development platform for building mobile and desktop web applications with TypeScript, JavaScript, and other languages. It provides components and templates, forms, APIs, server-side rendering, lazy loading, animations, and Angular Elements, along with the Angular CLI for creating workspaces, running local development servers, and managing projects. The project is hosted in the angular/angular repository and includes documentation, upgrade guidance, contribution guidelines, and an ecosystem that includes Angular Material.

Claude-Mem is an open-source persistent-memory plugin and service for coding agents. It captures agent activity through lifecycle hooks, stores sessions, observations, and summaries in SQLite, and uses hybrid full-text and Chroma vector search to retrieve relevant context across sessions. Its MCP search workflow uses progressive disclosure: the agent first searches a compact index, then reviews a timeline, and finally fetches full observations for selected result IDs. A local worker service, managed by Bun, provides the HTTP API, search endpoints, and web viewer; the project also supports integrations with Claude Code and other listed agent environments, configurable context injection, private-content exclusion tags, and optional cloud synchronization. The repository states that it is distributed under the Apache License 2.0 and requires Node.js 20 or later, with Bun, uv, and SQLite used by the runtime. It can be installed through its npx installer or Claude Code's plugin marketplace.

Co-op Anything is an open-source MCP server and playbook for directing AI coding agents to add cooperative multiplayer to single-player PC games. The MCP server searches a directory of more than 230 co-op mods, detects a game's engine from its installation folder, provides research and reverse-engineering guidance, and validates contributions. An agent either revives an existing mod by auditing and fixing its code or builds co-op from scratch by hooking into the game, synchronizing players, enemies, worlds, story, level changes, and saves. Builds are tested with bots driving real game clients, then packaged for installation and Steam-relay play without port forwarding. The repository includes agent skills, engine-specific guidance, networking and split-screen playbooks, automated QA procedures, game-specific projects, and contribution rules. It is licensed under the MIT License.

DeepTutor is an open-source, self-hostable AI tutoring platform developed by HKUDS for lifelong personalized tutoring. It provides a web application and command-line interface for interactive learning, problem solving, quiz generation, deep research, visualization, and mastery practice, with persistent memory and learning state shared across knowledge bases, books, notebooks, tutor personas, and other activities. The platform supports multi-agent problem solving, retrieval-augmented learning with source-traced and page-level citations, math animations, interactive visualizations, and tutor bots built from personal study materials. Its knowledge sources include personal documents, EPUBs and books with annotations, GitHub repositories, web search, and connected libraries; documented retrieval and ingestion options include GraphRAG, PageIndex, LightRAG, linked knowledge bases, Obsidian, and configurable parsing and vector backends. DeepTutor also includes courses, research workflows, an ecosystem of MCP services and tool or capability plugins, and integrations with connected coding agents and other partners. It can run locally or through Docker.

djs is a small JavaScript and TypeScript engine written in no_std Rust and built mainly for WebAssembly. It runs codemode scripts, including model-written programs that call tools, process their results, and return data; the project describes it as a QuickJS replacement for pi's codemode. The virtual machine stores all state in one byte array addressed by 32-bit offsets, allowing a new VM to be created by copying a prebuilt image and allowing the host to read results directly from that memory. Its interpreter avoids using the Rust call stack for JavaScript calls, so execution can be suspended between instructions and resumed inside callbacks, getters, and asynchronous functions. A suspended tool call can be serialized as a continuation dump containing JavaScript code that recreates the run. A single compilation pass produces stack bytecode while erasing TypeScript during parsing, and clock, randomness, and weak references are supplied by the host so identical inputs produce byte-identical heaps in native and WebAssembly environments. djs is distributed as the @earendil-works/djs npm package and also provides a Rust CLI for running scripts, starting a REPL, and disassembling code. Its behavior is tested against dquickts, a QuickJS fork, and the repository includes documentation, architecture notes, testing instructions, and a pi codemode adapter.

dsh-superagent is a research-prototype proactive coding agent for a single GitHub repository, packaged for DeepSeek Harness. It listens to GitHub and optionally Feishu; when an authorized person requests work, it creates a work item, runs the task in its own agent session and directory, and replies in the original conversation, potentially with a pull request. A web panel shows items requiring human attention, while authorization rules limit when it acts and what it communicates. The repository provides documentation covering its philosophy, domain model, authorization, execution, prompts, panel, deployment, architecture, and adding sources. It is research code rather than an official DeepSeek product or production-ready release, and is licensed under MIT.

etcd is an open-source distributed key-value store for critical data in distributed systems. Written in Go, it uses the Raft consensus algorithm to maintain a highly available replicated log and exposes a user-facing gRPC API for key-value reads and writes. It supports automatic TLS with optional client-certificate authentication and includes the etcdctl command-line client, client libraries, server packages, and release binaries for macOS, Linux, Windows, and Docker. etcd is distributed under the Apache 2.0 license.

Herdr is a desktop application for terminals and coding agents, written in Rust on top of Ghostty's terminal engine. It organizes work into spaces, tabs, and panes, while an agents sidebar collects agents from those spaces and shows whether each is working, blocked, done, or idle. Its core keeps terminals running after the window closes; panes and spaces can run on local or SSH-connected machines, with remote work continuing while the local window is closed or the computer sleeps. The app supports layouts and JavaScript mods for customizing panels, menus, and dialogs, and provides command-line commands for inspecting the window and agent-driving guidance. Herdr is distributed for Linux, macOS, and Windows, with installers and source-build instructions in its repository. Release builds check for updates in the background and enable usage telemetry by default, which can be disabled in the privacy settings.

Kiri is a lightweight container runtime for macOS, Windows, and Linux, developed in Rust as an alternative to Docker Desktop and OrbStack. It runs Docker images and supports the Docker CLI, Compose, buildx, Docker login, amd64 images through Rosetta, and the Docker Engine API. On macOS and Windows it runs containers in a small Linux virtual machine; on Linux it can use the host kernel. Its guest agent starts containers directly with clone3, namespaces, and cgroups, without runc, a shim, or dockerd. Kiri also provides a native interface for containers, images, volumes, and networks, local .kiri.local domains with HTTPS, one-command single-node Kubernetes clusters, and Linux machines. It is distributed for macOS, Windows through WSL 2, and Linux, and is licensed under Apache-2.0; the guest kernel is GPL-2.0.

LivLiv Player is a lightweight browser library for rendering animated 2.5D characters with WebGL2. Its dependency-free core is about 30 KB gzipped; it loads LivLiv model packages, VRM avatars, and PNGTuber images through related APIs, with expressions, actions, and parameter controls. Optional browser modules provide lip sync from microphone, audio, or video and webcam face tracking through MediaPipe, with camera images processed on the device. The package is distributed through npm as @livliv-dev/player, and the source code is licensed under Apache License 2.0. Featured characters included in the repository have separate licensing and usage terms.

LZ4 is a lossless compression library and command-line utility implementing an extremely fast compression algorithm. It supports block and frame formats, streaming through multiple blocks, dictionary compression using the final 64 KB of an input dictionary, and dynamically tunable compression speed through an acceleration factor. LZ4_HC provides a higher-compression variant that uses more CPU time, while retaining the same decompression method and speed. The project includes C APIs for block, high-compression, and frame operations, along with build support for Make, CMake, Meson, and Visual Studio. The library is licensed under the BSD 2-Clause license; the command-line utility is licensed under GPL-2.0-or-later.

Mago Studio is an open-source, local-first desktop AI video editor for Windows, macOS, and Linux. Mago Director turns scripts into casts, shot lists, storyboards, and connected scenes; Mago Transform applies frame-accurate edits to selected video ranges, including masked edits, relighting, character replacement, and style transfer. Projects and video remain on the user's machine by default, with rendering through ComfyUI on a local GPU or through Mago Cloud when signed in. Cloud renders upload only the selected Shot, its source video, reference images, and masks. The application can install a bundled ComfyUI setup on Windows or connect to an existing ComfyUI installation; local rendering is optional, and cloud models are paid. The app is distributed under the GNU AGPLv3, while downloaded models retain their own licenses.

OmniDiff is a Rust command-line diffing tool by Marko Ivankovic that compares files according to their content. It uses tree-sitter grammars to structurally diff 25 programming and markup languages, showing changes in terms of functions, classes, structs, and other syntax nodes rather than only line-by-line text; unknown extensions fall back to plain-text comparison. It provides an interactive terminal viewer, plain-text headless output for scripts and CI, JSON output, and integrations with Git and Jujutsu. It also compares non-text content, including pictures pixel by pixel, archives member by member, fonts glyph by glyph, message catalogs message by message, and PDFs page by page. It can be installed from source with Cargo, through prebuilt releases and several package managers, or used through VS Code and Neovim integrations. The project is distributed under the GNU Affero General Public License version 3, with a separate commercial license available through GitHub Sponsors.

PR-Agent is an open-source, AI-powered code review agent and community-maintained legacy project of Qodo. It reviews and explains pull requests through commands such as `/describe`, `/review`, `/improve`, and `/ask`, and can find similar issues with `/similar_issue`. Its PR Compression strategy is designed to process both small and large pull requests, while JSON-based prompting supports customization of review categories and behavior. PR-Agent can run through a CLI, GitHub Actions, Docker, self-hosted deployments, or webhooks, and supports GitHub, GitLab, Bitbucket, Azure DevOps, and Gitea. It connects to models from OpenAI, Anthropic, Google, DeepSeek, Mistral, Ollama, and other providers reachable through LiteLLM. The repository is distinct from Qodo's hosted AI code review offering.

Rust is a systems programming language and toolchain developed by the Rust project. Its compiler, standard library, documentation, package manager and build tool Cargo, formatter rustfmt, linter Clippy, and editor support are maintained in the main repository. The language uses a rich type system and ownership model to enforce memory and thread safety at compile time, while targeting fast, memory-efficient software for critical services, embedded devices, and integration with other languages. Rust is primarily distributed under the MIT and Apache 2.0 licenses, with portions under BSD-like licenses.

sand3d is a Python library for writing 3D objects as short programs designed for LLMs and human readers. Built over Blender's bpy, it represents profiles, solids, edits, frames, joints, groups, and assemblies as named parts; parts, edges, and faces are addressed by name rather than hand-computed coordinates, and the same program produces the same mesh deterministically. It can export meshes and articulated assemblies to GLB, URDF, OpenUSD, OBJ, and STL for web viewers, game engines, robotics and simulation tools, CAD workflows, and 3D printing. The library is distributed under the Apache License 2.0 and includes example programs, documentation, and datasets of procedural reconstructions.

terminal-mac is a macOS virtualization tool for giving computer-use agents a separate macOS desktop on Apple silicon Macs. It runs a real macOS guest through Apple's Virtualization framework; a helper app in the guest captures the screen and receives input events, while a terminal viewer streams the display through Kitty, Ghostty, or iTerm2. Agents control the guest through an MCP server with tools for screenshots, clicking, dragging, scrolling, typing, keyboard input, and status checks, without moving the host Mac's pointer or changing its clipboard. The guest has separate apps, files, accounts, and permissions, with host-to-guest communication through shared control and tools volumes. The project supports multiple virtual Macs, lifecycle commands, configurable virtual CPUs, memory, disk, and display settings, and optional offline operation. It requires an Apple silicon Mac running macOS 14 or later; initial setup requires downloading a macOS restore image and completing macOS setup and privacy permissions inside the guest. The repository describes it as an early release candidate, with self-signed releases and no Apple notarization.

Zed is a high-performance, multiplayer code editor developed by Zed Industries, Inc., the creators of Atom and Tree-sitter. It is available for macOS, Linux, and Windows through direct downloads or local package managers; web support is not yet available. The source code is licensed primarily under GPL-3.0-or-later, with marked components under Apache-2.0.
