DecentPaste lets computers and phones share clipboard content directly over the same Wi-Fi or LAN without accounts, subscriptions, or a central cloud service. Devices discover one another automatically, then pair with a six-digit PIN before exchanging end-to-end encrypted data. Prebuilt releases cover Windows, macOS, Linux, and Android; iOS is still listed as forthcoming, and mobile devices must keep the app open while pairing.

This repository provides a lightweight meta-skill rather than duplicating Streamlit's full development guidance. It detects the active Python interpreter, locates the installed Streamlit package, and points an AI assistant to bundled skills for dashboards, themes, layouts, session state, and components. Streamlit 1.57 and later ship those skills inside the pip package, while 1.58 adds the `streamlit skills` installer for project or global setup. Older versions fall back to online documentation, so the local workflow depends on an installed Streamlit environment.

NextClaw is a local-first AI workspace for tasks that span files, models, agents, browser tools, local applications, and messaging channels. It keeps references, generated results, and follow-up work together, while separate agents can have their own roles, memory, skills, runtimes, and workspaces. It can support research, data analysis, document drafting, file processing, and scheduled jobs through desktop or Docker deployments. Local configuration and credentials stay in the controlled environment, although connected providers receive the data sent to them.

Xcode 27 Skills redistributes Apple-authored Agent Skills exported from Xcode 27 for coding agents such as Claude Code and Codex. The collection covers SwiftUI patterns, UIKit modernization, Swift Testing migration, C bounds safety, Xcode security hardening, and on-device verification. Each top-level directory is self-contained, so developers can install only the guidance relevant to a task. The repository is a convenience redistribution; rights to the underlying Apple material remain with Apple, and the repository grants no license over it.

Asgard Skills is an open-source collection of 301 coding-agent skills across 22 domains, including research theories, algorithms, business frameworks, Taiwan-specific knowledge, ecommerce, law, data, and operations. Each standalone SKILL.md packages methodology, judgment rules, and common pitfalls for a defined task. Some skills also include dependency-free Python scripts for deterministic calculations in finance, statistics, supply chains, and ranking. The collection feeds Asgard plugins combined with MCP servers, and individual skills can also be used on their own.

frameless-titlebar is a React component for replacing the native chrome of frameless Electron windows with a configurable title bar and application menu. It supports common Electron menu item types and demonstrates overflow, stacked, and vertical menu layouts for constrained window sizes. Integration requires configuring BrowserWindow to remove or hide its native frame, then wiring window state and menu data into the component.

Gophie gives users a graphical way to navigate Gopher space, read text and menus, view images, search, and download files. It is available for Windows, macOS, and Linux, with a portable JAR option that requires Java 8 or newer. HTML content is not fully rendered inside the app, so related links may open in the system web browser.

Bootstrap an Angular 21 and Tauri 2 desktop application without wiring the frontend and native shell together from scratch. The template provides TypeScript, Sass, hot reload, a browser-only development mode, and commands for producing operating-system-specific bundles for Linux, Windows, and macOS. Its simple project structure separates the Angular renderer from the Rust-based Tauri process. Development requires Node.js 22 or later, a Rust toolchain, and the platform prerequisites listed by Tauri before the sample can run or package successfully.

MCK PPT Design Skill gives AI agents a consulting-style presentation system backed by a Python generation engine. Its workflow locks each slide's layout and takeaway in an outline, loads only the relevant design guidance, calls a library of slide and chart patterns, and runs machine-readable checks before and after rendering. It suits repeatable business-deck production and requires Python with python-pptx and supporting dependencies.

ntodotxt manages tasks in the portable `todo.txt` format, keeping the entire list in a single file rather than a proprietary database. Users can store that file only on the device or synchronize it through any chosen WebDAV server, including a self-hosted Nextcloud instance, with custom local and remote paths. Search and filtered views help organize the current list. The application remains under active development, and features such as sorting, recurring tasks, completed-task archiving, and import or export are still planned rather than available.

xint is a command-line tool for researching X/Twitter without leaving the terminal. It can search posts, watch topics over time, inspect profiles and threads, compare follower changes, and export results as JSONL or CSV for further analysis. The same capabilities can be exposed to agents through its skill and MCP interfaces. Core access requires an X API bearer token, while xAI credentials are optional for AI-assisted analysis and reports.

BrandDocs is an agent-skill bundle and Python CLI for generating new Word, PowerPoint, and Excel files from an organization's existing templates. It extracts a reusable brand profile covering themes, styles, structure, layouts, logos, tables, and spreadsheet rules, then builds new documents from the original template shell so formulas and native formatting remain intact. Each format stays separate rather than being converted into another. The workflow is local-first, but the full repository and Python dependencies are required; LibreOffice and Poppler are recommended for visual quality checks.

Founder Skills bundles reusable Claude Code workflows for SOP creation, conversion review, product requirements, go-to-market planning, content hooks, lead magnets, and social writing. The pack can be installed in full or one skill at a time through npx or manual copying. A project-level FOUNDER_CONTEXT.md file lets users supply company details, audience, positioning, brand voice, and goals so the same workflows can be adapted to different businesses or clients.

Superior Skills adds agent workflows for strategy authoring, backtesting, opportunity scanning, structured trade theses, and deployment through Superior Trade and Hyperliquid. The skills work with OpenClaw, Claude Code, Codex, and other compatible clients, but require the platform API and a trading account. The repository warns that its backtests cover a specific historical window and do not guarantee future performance.

Goal Forge interviews a rough idea into a SPEC.md with user-approved, measurable completion criteria, challenges ambiguous requirements, compiles the result into a structured GOAL.md, and performs a read-only Codex configuration check. Its contract captures a scorecard, fast feedback loop, slower final validation, working-memory files, and an optional control surface so multi-hour /goal sessions can remain coherent. The suggested unattended configuration can grant broad filesystem access and disable approvals, so it is intended only for project paths the user has explicitly trusted.

News KMP App is a reference project for building a news reader across Android, iOS, Windows, macOS, and Linux with Kotlin Compose Multiplatform. It demonstrates headline browsing, article details, search, bookmarking articles for later offline reading, networking, and local persistence through shared code. Developers need to obtain a News API key and configure it locally before running the desired mobile or desktop target from Android Studio or IntelliJ.

WinLens captures the Windows desktop, recognizes text with OCR, and draws translated lines over the original pixels with matched backgrounds and fonts. A global hotkey works across native apps, games, images, PDFs, chats, and video frames, and users can copy either the source or translation from each block. It is Windows-only, relies on online translation services, and its current builds are not code-signed, so SmartScreen may appear on first launch.

Marginalia keeps PDFs, notes, spreadsheets, logs, and archives in an ordinary folder tree while adding library-style metadata and retrieval indexes. When asked a question, its agent finds the relevant material and reads original file windows before composing a cited answer. It is available as a desktop app, CLI, reusable HTTP backend, and MCP server, with local storage by default; users still need to configure an LLM provider for generated responses.
