Recently updated open-source projects

P3X OneNote places the online OneNote experience in a dedicated desktop process instead of a permanent browser tab. It supports system-tray operation and multiple isolated tabs for personal or corporate Microsoft accounts, with per-tab labels, ordering, pinning, and zoom settings. The application remains a wrapper around Microsoft's online service, so it is not a separate offline note database.

@helpfeel/cosense-cli packages a command-line client and Agent Skill for reading, researching, and editing Cosense pages from compatible agents such as Claude Code and Codex. The skill depends on the globally installed CLI for its actual operations. Claude Code users can install it through the plugin marketplace and enable automatic updates, while Codex users install it with the skills tool and update it manually.

Use a desktop interface on macOS or Windows to discover, install, update, remove, and synchronize skills across coding agents. Its scanner checks for destructive commands, remote execution, credential exposure, Unicode tricks, disguised file types, and multi-step or cross-skill attack chains, with hard blocking for selected high-risk findings. The app also discovers and manages CLI tools installed through common package managers.

SciWrite applies a systematic editorial process derived from Kristin Sainani’s Writing in the Sciences course to scientific and engineering manuscripts. It reviews issues such as clutter, passive or weak verbs, and sentence structure in sequential passes, then suggests clearer alternatives. The skill can be installed in Claude or adapted to other tools that accept reusable instructions.

VexJoy Agent provides a single `/do` or `$do` entry point that selects a domain agent and a matching workflow skill from a plain-language request. The routed task proceeds through explicit phases with test, review, and verification gates backed by hooks and deterministic scripts. The toolkit covers software work as well as research, writing, data analysis, moderation, and self-contained HTML artifacts.

SwiftUI Design Skill helps Claude Code, Codex, Cursor, and similar agents establish visual direction before producing a SwiftUI interface. It asks for context and brand assets, offers differentiated design schools when requirements are vague, and guides typography, color, layout, placeholders, and a five-dimension review. Six anti-slop rules are intended to prevent generic AI patterns and overcrowded screens. The skill focuses on appearance, hierarchy, and brand feel; correctness, performance, and API modernization still belong to a separate engineering review.

WordPress Agent Skills contains early prototypes for creating WordPress themes and sites through Claude Code or Claude Cowork. A user describes the site, reviews specifications and design directions, and the workflow generates a block theme for deployment into a local WordPress Studio site. The accompanying Studio MCP server can create sites, write files, run WP-CLI commands, and produce shareable previews. The project is explicitly beta and experimental; its generated themes are not production-ready and may contain bugs or security issues.

Simple Music Player New Gen combines a local music library with online search and streaming on Windows, macOS, Android, and iOS. It handles formats including FLAC and DSD, imports playlists, displays synchronized lyrics, and offers queue, metadata, listening-statistics, and remote-control features. Online downloads are capped at 50 songs per day. The iOS build must be sideloaded, and installations signed with a free Apple ID expire after seven days.

Frigoligo is a cross-platform wallabag client for reading and synchronizing saved articles on Android, iOS, macOS, Linux, and Windows. Its offline-first design keeps reading available without a network connection and synchronizes changes when possible. Deep links and operating-system integrations let external workflows open a particular article, save a new URL, or navigate to app actions. Deep-link support is available on every listed platform except Linux. The app is a client rather than a standalone read-later service, so it requires access to a wallabag server.

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.

Radishes is a cross-platform music application with web and Electron editions. It supports searching artists, albums, playlists, and tracks, browsing recommendations and charts, playing synchronized lyrics, and downloading from configurable music sources and quality settings. The desktop edition also handles local music, ID3 metadata, download progress, and floating lyrics. Existing desktop releases are early builds, and feature availability differs across web, desktop, and mobile variants.

Octagon Skills provides agent workflows for financial statements, growth metrics, valuation, stock performance, market data, and broader company research. The skills are installed through npx, a Claude plugin, or manual copying, while live data access is supplied by the separate Octagon MCP service. Users therefore need to configure that MCP connection and an Octagon API key before the data-driven workflows can run as intended.

Infinite Image Browsing helps people manage large folders of AI-generated images and videos from tools such as Stable Diffusion WebUI, Fooocus, NovelAI, and StableSwarmUI. It indexes generation metadata for tag, filename, and advanced search, while also providing previews, file operations, comparisons, statistics, and bulk downloads. It can run as a desktop app, a standalone Python service, or a WebUI extension. Semantic clustering and natural-language search require an OpenAI-compatible embedding and chat provider plus additional Python dependencies.

Project Architect is a documentation-first agent skill for converting an idea into an implementation-ready blueprint. It asks structured discovery questions, then produces a specification, technical implementation plan, ordered task list with file targets and acceptance criteria, an optional branding guide, and a single synthesized prompt for a coding agent. Each document is presented for review before the workflow advances. The skill follows the Agent Skills specification and can be installed across Claude Code, Cursor, Codex, Gemini CLI, and many other coding agents.

@workersio/skills gives coding agents a risk-focused workflow for finding valuable test gaps, choosing an appropriate strategy, writing tests, generating replayable workloads, and reviewing existing cases. Its keep, redo, or remove gate asks whether a test would catch a failure that matters to users or operators rather than merely increasing coverage. It is packaged for Codex and Claude Code, while the Markdown-based workflow can be adapted to other skill-aware agents.

ElectronMail is an unofficial ProtonMail desktop client for Linux, macOS, and Windows. It supports multiple accounts, full-text search across message bodies, native notifications, per-account proxy settings, and export to EML or JSON. When its local store is enabled, message bodies are kept in an encrypted database for offline reading and search. Attachments are not stored for offline use, and several filtering or batch operations depend on the local-store feature.

Oxylabs Agent Skills help an assistant choose among proxy networks, Web Unblocker, structured scraping, remote headless browsers, and video data services based on the task. The collection installs through a Claude Code plugin or a generic skills command and includes product-specific usage patterns. Running those services requires the corresponding Oxylabs account credentials in environment variables.

Install individual Skywork skills to create or edit documents and presentations, build or analyze spreadsheets, generate images, search current web content, or make music. The collection works with several Agent Skills-compatible hosts, including Claude Code, Codex, and OpenClaw, using platform-specific installation paths. Some workflows call Skywork, Mureka, or related external APIs and therefore require the appropriate credentials.
