Recently updated open-source projects

Mapset Verifier is a desktop tool for osu! mappers who want to review a beatmapset with a consistent set of checks. It ships current builds for Windows, Linux, and macOS and can extend its built-in checks with custom DLL plugins. Those plugins execute inside the backend process with the same privileges as the application, so they should only come from trusted sources. Plugins built for the older 1.x line must also be rebuilt for the 2.0 runtime and API.

sports-skills gives SKILL.md-compatible agents structured access to public data for football, the NFL, NBA, F1, and other sports, with workflows that can compare ESPN, Kalshi, and Polymarket information. Read-only sports queries require no API key or signup. Premium licensed feeds and some real-time odds workflows instead route through the optional Machina service.

Kimi Skills gives AI agents dedicated workflows for creating and editing DOCX, PDF, and XLSX files. The skills cover structured document layouts, native charts, tracked changes, formulas, PivotTables, PDF processing, and output validation rather than basic text export alone. They can be installed together through npx, but each workflow relies on its own local toolchain, including combinations of .NET, Node.js, Python, Playwright, and OpenXML libraries.

WSL UI gives Windows users a graphical way to monitor WSL2 distributions, inspect CPU, memory, and disk usage, and open terminals, file explorers, or IDEs. It supports restart, export, import, clone, restore, custom actions, configuration editing, and disk mounting, and can install distributions from stores, container images, LXC catalogs, or custom URLs. The application is specifically for Windows systems using WSL rather than a general Linux manager.

Compose Agent Skill equips coding assistants with 24 practical guides and six source snapshots from AndroidX and Compose Multiplatform projects. Its routing workflow directs the agent to relevant material for state, modifiers, performance, navigation, side effects, and platform-specific behavior, helping it verify APIs instead of guessing. The plugin can be installed into supported hosts including Claude Code, Codex, Copilot, Cursor, and Gemini CLI.

FSNotes is a Markdown-first notes manager for macOS and iOS that also works directly with ordinary text files. Notes can live across multiple folders and sync through iCloud Drive or Dropbox, while tags, double-bracket cross-note links, code highlighting, and inline images support organization and writing. Encryption, optional Git versioning, and backups are available for users who want more control over stored files.

Install a collection used by the Sentry team for code review and simplification, commits and branch creation, Django access or performance checks, documentation, API endpoint work, and brand-aware writing. It is available as a Claude Code marketplace plugin or a standard skills package for compatible agents, helping coding assistants follow Sentry's engineering and content practices.

sql_to_ER is a browser-based, front-end-only tool that turns SQL CREATE TABLE statements or DBML into Chen-model entity-relationship diagrams. Users can drag nodes, edit them by double-clicking, zoom or rotate the canvas, and run an automatic layout pass after generation. The hosted version requires no sign-in or installation, and the project can also be installed as an Agent Skill. It targets Chen diagrams rather than logical models, and local source use must run through Vite instead of opening the HTML file directly.

Thesis Defense PPTX Skill extracts content and candidate figures from a local PDF or LaTeX project, then places a concise defense narrative into a supplied PowerPoint template. It aims to preserve the template's cover, typography, colors, navigation, card styles, and aspect ratio while producing a genuinely editable PPTX rather than image-only slides. The workflow can export pages, build a contact sheet, detect text overflow, and scan for leftover template wording. Basic generation is cross-platform, but full quality checks are recommended on Windows with Microsoft PowerPoint.

PSLab App connects to Pocket Science Lab open hardware over USB and turns a phone or computer into an experiment control and data collection interface. The device can act as an oscilloscope, waveform generator, frequency counter, programmable voltage or current source, and data logger. The app spans mobile, desktop, and web, but the core experiments require PSLab hardware.

EasyClaw is a desktop installer that reduces OpenClaw setup to downloading the app, running the installer, and entering an AI provider key. It can detect and install required components such as WSL, Node.js, and OpenClaw on Windows, and it also supports connecting the resulting agent to a Telegram bot. Builds are available for Intel and Apple Silicon Macs as well as Windows, although Windows may still display a security warning while code signing is pending.

Design Buddy is a collection of visual-production Agent Skills for creators, product managers, independent developers, and design collaborators. It first interprets the content and selects an appropriate visual structure, then produces outputs such as article covers, illustrations, infographics, architecture diagrams, logos, storyboards, slide decks, WeChat layouts, or social images. Users can install the full repository or copy individual skills, while the available output formats and generation steps still depend on the chosen agent runtime and image services.

Skald packages document ingestion, chunking, embeddings, vector storage, retrieval, and cited chat behind a configurable API. Teams can tune search, reranking, models, and query rewriting, then evaluate the resulting RAG setup through the same platform and access it from several language SDKs. It can run as a hosted service or through Docker in your own environment; a fully local deployment also requires self-hosted LLM inference and embeddings.

Install these skills in Claude Code, Cursor, or Codex to steer Rails work toward rich domain models, CRUD-oriented routing, Hotwire, fixtures, and vanilla framework features. Separate skills cover migrations, jobs, security, multitenancy, testing, and an opinionated DHH-style review mode. This is an unofficial community project, and much of the material was assembled through LLM analysis, so important guidance should be checked against real implementations.

UI Skill Lab is a reference workflow that turns a PRD into a visible UI target before an agent writes code. After review, it extracts visual specifications, tokens, layout rules, a component tree, evidence, and prohibited assumptions for Codex or Claude Code to implement. Screenshot acceptance and focused diff tasks guide repairs. It works best for HTML/CSS-heavy dashboards, SaaS products, admin interfaces, mobile screens, and ordinary landing pages. It is not a complete UI generator and does not automatically slice images or export Figma, PSD, or Sketch assets.

Claude Code ASO Skill turns App Store Optimization for iOS and Android into guided agent workflows. It can prepare keyword research, metadata drafts, action lists, reports, and executive summaries. Developers can install the coordinated multi-agent system in Claude Code, while other users can upload the standalone ZIP skill to Claude Desktop or the web app for conversational analysis. Some workflows fetch live store data and therefore require an internet connection; app teams should still review the resulting positioning and store copy before use.

EasyDB treats CSV, TSV, text, JSON, Excel, and Parquet files as tables that can be queried directly from a macOS or Windows desktop app without installing a separate database or converting the files first. It can also read MySQL and PostgreSQL tables and combine sources with joins, subqueries, and window functions. Dragging a file into the editor generates SQL, and results can be exported as CSV, TSV, or database-specific SQL.

Create paper figures through two distinct workflows: image generation for architectures, schematics, and graphical abstracts, and local plotting for benchmarks, ablations, heatmaps, or any panel where values must remain exact. The skill includes bilingual figure briefs, scripts, and editable handoff formats. Conceptual image generation requires a supported provider such as OpenAI or Gemini-compatible services.
