Dr JSkill is an Agent Skill for creating Spring Boot applications according to a defined set of Java development practices. It guides compatible coding assistants through generating projects from start.spring.io and configuring Java 25, PostgreSQL, REST APIs, monitoring, Docker builds, and a choice of Vue, React, Angular, or vanilla JavaScript. The repository also includes references for databases, testing, deployment, and a hands-on workshop. It is not a standalone scaffolding application and must be loaded by a supported agent such as GitHub Copilot CLI or Claude Code.

AgentRL separates agent reinforcement-learning training from environment deployment. Rollout, actor, and reference workers run on Ray to generate trajectories, update the policy, and maintain a frozen KL baseline, while a controller and task workers manage multi-turn environments over HTTP or gRPC. It is suited to reproducing the paper’s experiments or adding tasks, but training requires Ray, suitable CPU/GPU resources, and model configuration.

This agent skill gives coding assistants 70 Playwright guides with TypeScript and JavaScript examples for authoring tests, debugging failures, CI, CLI automation, page objects, and migrations. You can install the whole repository or only the relevant skill pack, and the agent loads the appropriate guidance on demand. Its documented coverage targets Playwright 1.61 and recent releases.

Use TanStack Intent to generate and validate Agent Skills for a library, then ship them alongside the related npm package. The skills are auto-discoverable, versioned with the code, and compatible with the open Agent Skills standard, helping maintainers keep agent guidance aligned with each library release.

KhinsiderDownloader lets you search albums on downloads.khinsider.com and download their tracks in bulk through a desktop interface. Its worker pool handles downloads concurrently, and releases are available for Windows and Linux, with nightly builds for testing. The application does not host the music itself, so users remain responsible for the source site’s terms and the rights attached to downloaded material.

claude-cmd gives Claude users one CLI for maintaining custom commands, project-specific CLAUDE.md files, security profiles, MCP servers, and settings. It can search local or GitHub-backed command collections and install selected entries, making it useful when several projects share reusable workflows.

Porda AI is an on-device Windows application for users who want to maintain Islamic modesty while browsing or watching media. It detects and covers non-mahram people and NSFW objects directly on screen across browsers, video players, and other applications, with hotkeys and per-app controls. Processing stays offline, but very small objects may be missed, performance depends on the computer, and GPU acceleration is currently limited mainly to Intel OpenCL hardware.

DataPup is a cross-platform database client for developers who want a graphical place to write, run, and inspect SQL with AI-assisted query support. The current documentation lists ClickHouse and PostgreSQL as supported databases, with database-specific query execution already available. MySQL and SQLite are described as upcoming rather than usable today. The provided getting-started path focuses on installing source dependencies, running the development build, or creating a distributable package.

Daiso MCP exposes Korean retail, local-information, and cinema lookups through a remote MCP server, the `npx daiso` CLI, and a Codex skill. It can search stores, products, and stock across Daiso, convenience chains, Olive Young, and major retailers, compare selected prices, find nearby venues or fuel stations, and check movie schedules and remaining seats. End users can access the supported services without preparing separate API keys.

AgentSkillsHub continuously collects Agent Skills, MCP servers, Codex skills, and other agent tools from GitHub. Its web directory and API provide search, filtering, quality scores, security grades, trending lists, rising projects, and related-project views. The classifications and scores are generated through scheduled synchronization, deduplication, enrichment, and multi-dimensional rule-based analysis.

Devo is a model-neutral coding agent with both a desktop application and a terminal TUI/CLI backed by the same local Rust runtime. It connects to OpenAI-compatible or Anthropic-compatible APIs, DeepSeek, Qwen, Kimi, private gateways, and local endpoints, while adding semantic code search, MCP servers, reusable skills, and multi-agent work. It is designed for private and intranet environments as well as normal local use. Current macOS desktop builds are unsigned and require manually removing the quarantine attribute after installation.

MagicSkills keeps reusable `SKILL.md` directories in one local pool and lets users compose named subsets for different agents or workflows. Runtimes that read `AGENTS.md` can receive a synchronized skill section, while agent frameworks can use the same collection through a command-line or Python tool interface. It is aimed at multi-agent projects that want to avoid copying and drifting skill folders, and requires Python 3.10–3.13 plus Git.

Mini-Kode is an educational coding assistant that presents modern agent architecture in a compact but complete terminal project. Its code shows how tools, model calls, permission approval, streaming, and the agent loop fit together, with file operations, search, command execution, and MCP integration available for developers to study and modify.

This kit helps creators choose AI video models, translate prompts between model formats, and reuse tested workflows for storyboarding and debugging. It combines a large prompt library with Claude skills, methodology guides, and automated monitoring of official endpoints, making it useful for comparing or moving work among Seedance, Kling, Sora, Veo, and related systems.

LoFloccus is a Windows and macOS companion for the Floccus browser extension. It exposes one chosen folder through a small, self-contained WebDAV service, allowing bookmark files to be synchronized further with Dropbox, Syncthing, rsync, or another tool that works with local files. Each setup receives a random port, username, and password, while access is restricted to one directory and a narrow set of bookmark-related file types. It is useful when browser restrictions prevent Floccus from writing directly to disk.

mizchi/skills packages practical engineering guidance into independently installable skill directories covering frontend reviews, Node.js, AWS, Cloudflare, SQL, DevOps, languages, and related tooling. Each skill follows the open Agent Skills format and can be installed with APM, the skills CLI, or a direct folder copy. Compatible agents such as Claude Code, Codex, Cursor, opencode, and Gemini CLI can consume the same skill files.

Memospot packages Memos as a self-contained desktop application for Windows, macOS, and Linux, allowing users to take notes offline without deploying a server first. It can also operate as a client for a remote Memos instance, and data can be moved between local and hosted installations. The app relies on the platform’s system WebView, and unsigned builds may trigger SmartScreen or unidentified-developer warnings during installation.

OCTO Web is the browser and Electron desktop client for the OCTO messaging platform, with both surfaces built from the same React codebase. Its chat UI distinguishes humans from agents and supports streaming replies, typing indicators, inline tool-call previews, and read receipts in English and Simplified Chinese. It is a client rather than a standalone service and must connect to an octo-server instance.
