Recently updated open-source projects

writing-style-skill provides a reusable template for Claude Code and OpenClaw that improves from the user's own revisions. It records the original AI draft and the final edited version, compares them, extracts recurring preferences, and updates SKILL.md so later drafts follow those rules. The observation step is a dependency-free Python script, while automatic rule extraction and application require an available Claude CLI, the llm command, or a user-configured LLM command.

Psysonic is a desktop music client for self-hosted libraries, designed primarily for Navidrome while also connecting to Gonic, Airsonic, LMS, and other Subsonic-compatible servers. It analyzes loudness, waveforms, and tempo on the user's machine to support normalization, playback-speed controls, and content-aware AutoDJ transitions. Navidrome users also get direct access to server-native features such as smart-playlist editing and playback reporting. Other servers may work well, but advanced behavior depends on the capabilities they expose.

Use this multilingual guide to understand skill structure, installation paths, marketplaces, and common management tools across agent ecosystems. It curates official skill repositories from model providers, cloud platforms, and developer-tool vendors, while comparing usage in apps, coding agents, and OpenClaw-style harnesses. The guide also highlights security review practices; its bundled creation and testing toolkit is currently limited to Claude Code.

ConvertX runs as a self-hosted web application where users upload files, process several at once, and download converted results. Its container combines specialist converters for documents, images, e-books, audio, video, and structured data, covering more than a thousand format paths, with accounts, password protection, and scheduled cleanup. After deployment, the first administrator account should be created immediately, and an unconfigured instance should not be exposed publicly; non-local access expects HTTPS by default.

The pack lets Claude Code or Cursor drive the Arcads API to create short videos, static Meta ads, thumbnails, and multi-step animated campaigns using model-specific prompt libraries. Basic image and video workflows require Python 3.10+ and an Arcads API key, while captioning, stitching, or publishing pipelines may also need ffmpeg, Node.js, or other CLI tools.

Clawd on Desk turns agent activity into an animated pixel pet that reacts to thinking, typing, permission requests, subagent work, and completion. A session dashboard helps track several tasks at once, while Claude Code and Codex connect automatically and other agents can be configured manually. It runs on Windows, macOS, and Linux, with an optional read-only phone view over the local network.

SafeLine runs as a self-hosted reverse proxy in front of web applications, filtering HTTP traffic before it reaches the origin server. Administrators can use it to block common attacks such as SQL injection and XSS, enforce traffic limits, and present bot or password challenges. It requires deployment and routing changes on your own infrastructure; users in mainland China are directed to the Chinese installation path because the international edition may not connect to its cloud services.

This repository packages creative production, presentations, video, Google Workspace, advertising analysis, and other workflows as portable SKILL.md modules. Users can install the collection across Claude Code, Copilot, Cursor, Windsurf, and related agents, while some skills still require local tools such as ffmpeg, Node, Python, or credentials for external services.

COMPASS Skills helps preserve the context that usually disappears across long agent sessions. Its local workflows clarify ambiguous work, maintain a repository task graph, create paste-ready handoffs, and keep an auditable collaboration profile; additional skills turn execution history into new skill designs or upgrade plans. Runtime data stays local by default, but the user profile is stored as unencrypted plaintext and should not contain secrets.

RapidRAW is a lightweight RAW editor for Windows, macOS, Linux, and Android, using a GPU-accelerated 32-bit processing pipeline for responsive, non-destructive adjustments. It includes layer masks, subject and sky detection, and optional generative edits through an AI backend. For high-resolution RAW files and complex masking, the project recommends at least 16 GB of memory and a reasonably modern dedicated GPU.

rnskill collects project-level skills for Chinese prose editing, motion-first video direction, original reference-motion studies, dark SaaS product videos, typed text openers, and evidence-based replica quality control. It works with Codex, Claude Code, and other SKILL.md-compatible agents, and users can install the whole collection or select individual skills. The repository uses a CC BY-NC 4.0 license, so commercial use requires careful review of the license terms.

Equip coding agents with Vercel-maintained guidance for auditing deployment cost, performance, caching, and reliability; optimizing React, Next.js, and React Native code; reviewing web accessibility and UX; enforcing documentation standards; and creating claimable Vercel deployments. Once installed, the relevant skill becomes available when matching tasks are detected.

Gmail Cleaner is a local or Docker-hosted web interface for reducing an overloaded Gmail inbox. It can group and filter messages by sender, date, size, category, or label, then bulk unsubscribe, delete, archive, mark messages read or important, manage labels, and export selected metadata as CSV. Setup requires the user to enable the Gmail API in a personal Google Cloud project, create OAuth credentials, and add the Gmail address as a test user. Because the OAuth app is personal and unverified, Google displays a warning that should be reviewed before granting access.

IPTVnator loads M3U or M3U8 playlists from files or URLs and also supports Xtream Codes and Stalker portals. Its desktop app adds channel search, EPG guides, catch-up viewing, and external players such as VLC or MPV. The self-hosted PWA covers browser playback but omits desktop-only features including EPG panels, embedded MPV, and download management.

AltSendme sends files or entire directories directly between devices instead of uploading them to a cloud drive. It works across desktop, Android, terminal, and browser clients, uses QUIC with TLS 1.3, verifies content with BLAKE3, and can resume interrupted transfers. The project is still marked as work in progress despite offering downloadable builds.

Go Music DL brings multi-platform song, playlist, and album search into one interface, with playback, downloads, batch actions, source replacement, and local library management. It can run as a web app, terminal interface, desktop app, or mobile build. Some personal playlists and higher-quality sources require platform cookies, while metadata embedding and related enhancements may depend on FFmpeg.

Pangolin combines a WireGuard-based VPN with tunneled reverse-proxy access for infrastructure spread across different networks. Authorized users can open web applications, VNC, RDP, and SSH sessions in a browser, while clients provide access to private hosts, databases, and network ranges. Site connectors use outbound tunnels and NAT traversal, so protected networks do not require public IP addresses or inbound ports.

softspark ai-toolkit distributes a broad set of skills, 44 specialist agents, lifecycle hooks, shared rules, personas, and optional plugin packs across many AI coding environments. It supports planning, debugging, review, TDD, commits, pull requests, documentation, orchestration, and parallel workflows, with adapters for Claude, Cursor, Windsurf, Gemini, Copilot, Codex, OpenCode, and others. Executable hooks can block selected destructive operations and enforce quality or session policies, although platforms without hook support receive guidance rather than equivalent machine enforcement.
