Agent Desktop is a Rust-based CLI and C library for letting AI agents inspect and operate desktop applications through operating-system accessibility trees rather than pixel matching. It returns JSON snapshots containing stable, snapshot-scoped references for actionable elements; agents act on those references and take another snapshot to verify the result, while stale or ambiguous references produce structured errors. It supports macOS, Windows, and Linux, with commands for application and window management, keyboard and mouse input, clipboard access, notifications, screenshots, sessions, and batch operations. It can be installed from npm with platform-native binaries or used through release archives and its FFI library. macOS requires Accessibility permission, Linux requires a graphical session with at-spi2-core, and the project is licensed under Apache-2.0.

Auto-Ontology is an open-source Python framework and service from NVIDIA that builds a semantic, graph-based context layer over enterprise databases for LLM and agent workflows. It ingests schemas, column profiles, sample values, and query history, then compiles business terms mapped to columns, reviewed SQL attributes, and inferred table relationships into a PostgreSQL-backed ontology with pgvector embeddings. People can inspect, edit, test, and certify the generated definitions through a web UI or API. An agent resolves question entities to ontology terms, retrieves candidate columns and SQL attributes, generates SQL, validates filter values and the query against the source database, repairs failed queries, and returns the answer with its SQL and execution steps. The system can check whether a question is answerable before querying and exposes read-only ontology and question-answering tools through MCP, agent skills, and a REST API. It supports PostgreSQL, MySQL, Databricks, Snowflake, ClickHouse, Trino, Apache Kyuubi, HeavyDB, DuckDB, and SQLite, and can run with Docker Compose. The repository is licensed under Apache-2.0.

Context Mode is an MCP server and plugin for AI coding agents that reduces context-window usage by routing large tool outputs through sandboxed subprocesses. Its execution tools run code in supported languages, process files, fetch and analyze URLs, and return selected stdout or search results instead of exposing raw logs, snapshots, API responses, or file contents to the conversation. The project reports up to 98% context reduction in its benchmarks. It also provides session continuity across supported agents. Hooks capture tool calls, edits, prompts, decisions, errors, and other session events in SQLite; before compaction, the system builds a prioritized resume snapshot, and after compaction or session resumption it retrieves relevant events through SQLite FTS5 search with BM25 ranking. Content indexing uses heading-aware chunking, stemming, trigram matching, reciprocal-rank fusion, proximity reranking, fuzzy correction, and smart snippets. The MCP interface includes execution, batching, indexing, search, fetching, statistics, diagnostics, upgrade, and purge tools. Context Mode supports multiple coding-agent platforms through MCP servers, native plugins, and platform-specific hooks, with automatic routing enforcement where hooks are available and instruction files for platforms without them. The repository states that processing and SQLite storage are local, with no account or telemetry requirement. It is licensed under the Elastic License 2.0, which permits use, modification, and distribution but restricts offering the software as a hosted or managed service and removing licensing notices.

Floci is a free, open-source local AWS emulator for development, testing, and CI. It exposes AWS-shaped services at a local endpoint, allowing existing AWS SDKs, CLI commands, Terraform, CDK, OpenTofu, and test suites to target the emulator without a cloud account or authentication token. Its router serves in-process stateless and stateful services, while services such as Lambda, RDS, Neptune, ElastiCache, MSK, ECS, EC2, EKS, OpenSearch, and CodeBuild use real Docker-backed execution where the project considers it important for fidelity. Floci supports memory, persistent, hybrid, and write-ahead-log storage modes, provides a browser console, and includes Testcontainers modules for isolated instances in tests. It runs through the Floci CLI, Docker or Docker Compose, or standalone binaries for Linux, macOS, and Windows, and is distributed under the MIT license.

Ghostty is an open-source, cross-platform terminal emulator with native platform interfaces and GPU acceleration. It uses a shared core written in Zig, a SwiftUI and Metal application on macOS, and a GTK application with OpenGL on Linux. Its multi-threaded architecture gives each terminal dedicated read, write, and render threads, while a SIMD-optimized parser handles terminal control sequences. It supports tabs, panes, multiple windows, Kitty graphics and image protocols, clipboard sequences, synchronized rendering, and other modern terminal features. Ghostty also provides libghostty, a zero-dependency, C-compatible C and Zig library for embedding terminal functionality in other applications. The related libghostty-vt library parses terminal sequences and maintains terminal state, with support for macOS, Linux, Windows, and WebAssembly.

GitHub Spec Kit is an open-source, community-driven toolkit from GitHub for spec-driven software development with AI coding agents. It provides the Specify CLI to initialize projects and create feature branches, establishes project principles in a constitution, defines specifications, plans implementations, breaks plans into actionable tasks, implements them through an agent, and checks the result against the specification, plan, and tasks. The toolkit supports integrations with AI coding agents and includes extensions, presets, role-based bundles, and an opt-in bug-fixing extension with an assess–fix–test workflow.

Grim Prompter is an open-source library of threat-modeling prompts and an agent skill for Claude Code, Codex CLI, and other AI coding agents. It directs an agent to inspect a repository read-only, model its architecture and trust boundaries, identify threats and existing controls, propose mitigations, and produce reports with file-and-line evidence. The library provides workflows for dozens of architecture types and security methods including STRIDE, PASTA, LINDDUN, MITRE ATLAS, attack trees, and FMEA; its deep workflow proceeds through scope, system modeling, threat analysis, challenge, treatment planning, and reporting, with JSON artifacts that support later reviews and change comparisons. Results are written under a threat-model directory, and the project warns that generated prompts and reports require human review. The repository and documentation are licensed under the MIT License.

gstack is an open-source skill and tooling framework for Claude Code, developed by Garry Tan. It turns Claude Code into a virtual engineering team through Markdown-based slash commands and specialist roles covering product review, engineering management, design review, code review, browser-based QA, security auditing, release management, documentation, and other software-delivery tasks. Its tools can drive a real browser and support unit-test, end-to-end-test, and black-box verification loops. The repository describes 23 specialist tools and eight power tools, and distributes the project under the MIT license. It requires Claude Code, Git, and Bun; Node.js is additionally required on Windows.

HyperFrames is an open-source framework for turning HTML, CSS, media, and seekable animations into deterministic MP4 videos. It can be used locally through a CLI, by AI coding agents through skills, or as a rendering core for hosted authoring workflows. Compositions are defined as HTML with data attributes for timing, tracks, media, and sub-compositions. The renderer seeks each frame in headless Chrome, uses animation adapters such as GSAP, CSS, Lottie, Three.js, Anime.js, or WAAPI, and encodes the result with FFmpeg; its toolchain includes preview, linting, inspection, local rendering, browser-based editing, reusable catalog components, and AWS Lambda rendering. The project requires Node.js 22 or newer and FFmpeg, does not require React or a build step, and is licensed under Apache 2.0. Its agent skills support workflows including product videos, explainers, pull-request videos, captions, motion graphics, slideshows, music-driven videos, and general compositions.

Hyprland is an independent, dynamic tiling Wayland compositor developed by the Hyprland project. It supports tiling, pseudotiling, floating, and fullscreen windows; special workspaces, window groups, dynamic workspaces, multiple layouts including Dwindle, Scrolling, Master, and Monocle, and per-workspace layouts. Its Wayland implementation includes socket-based IPC, global keybinds, window, monitor, and layer rules, native input-method support, tearing support, and configuration reloading when files are saved. Hyprland is implemented independently rather than using wlroots, libweston, KWin, or Mutter. It provides customizable animation curves, visual effects such as gradient borders, blur, animations, glow, and shadows, plugin support with a built-in plugin manager, and custom layouts through Lua or plugins.

REA is a local reverse-engineering tool for AI agents, distributed as a CLI and MCP server. It connects agents to analysis providers such as Hopper and Ghidra, and can inspect native binaries, macOS applications, JavaScript and Electron applications, .NET assemblies, websites, packages, and controlled runtime behavior. Its investigation workflow decompiles or maps a target, follows strings, symbols, calls, references, and control flow, records evidence and limitations, and uses the findings to help reconstruct features in another project without claiming to recover original source code or automatically clone an application. Analysis runs on the local host; REA configures agent integrations and can optionally install Hopper, while Ghidra and Java must be installed separately. The project is distributed under the MIT license.

Scrapling is a Python web-scraping framework for fetching, parsing, and crawling websites from a single request to a full-scale crawl. It combines fast HTTP requests, browser-based JavaScript rendering through Playwright, stealth fetching, persistent sessions, proxy rotation, retries, concurrent spiders, pause and resume, and background capture of API responses. Its parser supports CSS and XPath selectors, text and regular-expression search, adaptive element tracking, similar-element matching, DOM navigation, and Markdown output. Scrapling provides a Scrapy-like spider API with async parsing, throttling, blocked-request detection, optional robots.txt compliance, ready-made crawl templates, link extraction, and JSON, JSONL, CSV, and XML exports. It also includes a CLI, interactive shell, MCP server for AI agents, an Agent Skill, and tools for producing sanitized Markdown suitable for retrieval-augmented generation. The core package requires Python 3.10 or later; browser, AI, RAG, shell, and combined features are available through optional dependencies. The project is distributed under the BSD-3-Clause License and provides Docker images with browser dependencies.

Superpowers is an open-source agentic skills framework and software development methodology for coding agents. It begins by eliciting and presenting a software specification for approval, then produces an implementation plan emphasizing red/green test-driven development, YAGNI, and DRY. After approval, it uses a subagent-driven-development process in which agents implement engineering tasks, inspect and review the results, and continue according to the plan. It is distributed as a plugin for supported coding-agent harnesses, including Claude Code, Codex, Cursor, and others.

T3 Code is an open-source agent-harness control surface for coding agents running on a developer's computer. It provides iOS and Android mobile apps, a web app, and an Electron-based desktop app for controlling locally configured Codex, Claude Code, Cursor, Grok Build, and OpenCode agents while using the user's existing provider subscriptions. The project can be launched with `npx t3@latest`, which starts its backend and local web interface on the machine. It also distributes desktop builds for Windows, macOS, and Arch Linux, and supports remote access from a phone or another machine. The repository describes the project as early-stage and warns that bugs are expected.

ub-mode is an agent skill that applies disciplined software-engineering practices when an AI coding agent writes or changes code. Its workflow separates making code work from making it right: it uses foundational thinking, test-driven development, premise checking, domain and boundary modeling, type-system discipline, idempotent operations, root-cause fixes, behavior-focused testing, and refactoring, with work organized into verifiable units and small ordered commits. It pairs these rules with deterministic quality gates: crapper measures complexity, coverage, and CRAP scores; dryer detects structural duplication; mutator performs mutation testing; and uml-viewer visualizes components, coverage, mutation scores, and dependency directions. The skill is installed by copying SKILL.md into an agent's skills directory and invoking /ub-mode.

Worktrunk is a command-line interface for managing Git worktrees, designed for running AI coding agents in parallel. It addresses worktrees by branch name and computes their paths from a configurable template; its core commands switch to, list, merge, and remove worktrees, with an option to launch a command such as Claude Code after switching. It also provides hooks for local workflow automation, LLM-generated commit messages, merge and cleanup workflows, an interactive worktree picker with diff and log previews, shared build caches, CI status and AI-generated branch summaries, pull-request checkout, per-worktree development-server ports, and aliases with branch-scoped variables. It can be installed through Homebrew, Cargo, Winget, Arch Linux, Conda, or Pixi, and shell integration enables commands to change directories.
