Elements is a focused desktop application for displaying the chemical periodic table in its own window. Prebuilt downloads are provided for macOS, Windows, and Linux, making it useful when a simple standalone reference is preferable to a browser page. Running or building the source requires Node.js, Git, and Bower.

Agent Skills CLI manages skills across tools such as Claude Code, Cursor, Codex, and other coding assistants from one command line. It can install from a marketplace, public or private Git repositories, and npm packages, then update or synchronize selected targets. Lockfile-based installs, conflict checks, quality tests, and sandbox previews help users inspect collections before wider rollout. The CLI requires Node.js 18 or later.

Share a precise part of your Windows screen even when a meeting app only supports whole-window sharing. The tool opens a transparent, click-through capture frame and a separate rendering window; resize or move the frame, then select the rendering window in Teams or another conferencing app. A Windows executable is available from releases, while source builds and command-line options let users preset coordinates, dimensions, display scaling behavior, and maximum capture frame rate.

ir-search is a Korea-only skill for surveying open government support programs across K-Startup, Bizinfo, NIPA, KOCCA, and SMTECH. It profiles a project by startup stage, region, and needs such as funding, space, or R&D, then checks eligibility against original notices. Results separate opportunities available now, programs unlocked by future milestones, and options that may fit after reframing the project. Reports, raw JSONL, and notices are saved locally; repeat runs highlight new, changed, and closed opportunities. Applicants should still confirm details with the issuing agency.

Agent-Skills-Hunter collects portable skill packages for creative work, Office documents, Obsidian, development, testing, debugging, orchestration, Git workflows, and integrations. Each skill is organized around a `SKILL.md` file and may include scripts, templates, or references. The included skillctl tool can search, enable, disable, and update selected skills for compatible environments such as Claude, Codex, Copilot, or Gemini. It is a library of implemented skills and a management entry point, not one application that runs every workflow by itself.

Kansoku is a local-first Apple Silicon macOS app for the full cycle of watching, analyzing, and reviewing US stocks. It combines live Longbridge data, multi-timeframe charts, locally computed indicators, event calendars, scenario analysis, strategy dashboards, and frozen journal records. Users must install and sign in to the Longbridge CLI, while model choices, keys, analysis traces, and research files remain on the machine.

LazySkills brings project, global, universal, and agent-specific skills into one terminal UI. It shows which coding agents can actually use each skill, flags broken installations or metadata, and previews commands before update, reinstall, removal, or bulk actions. It can also search skills.sh and inspect additional skills from local or GitHub sources.

Easy Link File Viewer opens Windows .lnk files in a focused desktop editor, exposing properties that the standard Windows dialog does not make easy to inspect or change. Users can repair broken targets, replace icons, review raw structure in a read-only hexadecimal viewer, and save changes to the original shortcut or a copy. The portable app supports drag and drop and multiple simultaneous instances, making it useful for administrators, developers, and power users maintaining many shortcuts.

Pomosh keeps a Pomodoro session visible in the macOS menu bar so you can follow work and break cycles without reopening the app. Set the duration and number of cycles, then use notifications, sounds, the countdown, or a global shortcut to track progress. You can pause the timer and skip or restart the current round when plans change.

Truck Nav provides an external GPS for Euro Truck Simulator 2 and American Truck Simulator. A Windows desktop component reads live game telemetry, while an Android app or any browser on the local network displays position and routing on a phone, tablet, or second monitor. The core navigation works, but the project is still labeled an alpha or demo and may lag on older devices. It supports the base games and all DLC through version 1.58, but not map mods such as ProMods, and some company-name mods can break routing.

Yagua brings common image-processing jobs into a local desktop interface for designers, photographers, and web developers. It can batch-compress and convert files, resize or crop them, remove backgrounds, run OCR, vectorize images, and edit EXIF data without relying on a subscription web service. Windows and Linux are the main supported platforms, macOS remains experimental, and each module has its own practical batch limit.

Shopify Admin Skills is a collection of installable agent workflows for merchandising, inventory, orders, marketing, support, fulfillment, finance, and other store operations. Each skill works through the Shopify Admin GraphQL API, previews mutations with a dry run, and waits for confirmation before execution. Scheduled routines can monitor areas such as stock, fraud, fulfillment, and business health, while the smart installer helps choose only the routines that fit a store.

Purge helps reclaim Mac storage by scanning application caches, system junk, and developer artifacts from tools such as Xcode, Homebrew, npm, Docker, and project build folders. A separate large-file view searches common personal folders with size, age, type, Quick Look, and Finder controls. Deletions go to the Trash by default rather than being permanently erased.

Refloow Photo Studio is a cross-platform desktop editor for quick photo work without an account or cloud upload. Users can remove backgrounds, crop and mirror images, adjust color, apply built-in filters, add text, and compose layers while keeping the files and editing process on their own machine.

OpenAver is a graphical collection manager for Windows and Apple Silicon Macs that gathers JAV metadata, artwork, tags, and performer information from multiple sources. Users can browse a local library through cover walls and filters, then generate NFO, poster, and fanart files for Jellyfin, Emby, or Kodi. A local REST API also supports multi-step catalog operations by AI agents. Data stays in a local SQLite database; files are moved or renamed only during explicit organization actions, and the project states that source videos are not deleted.

skill-publish is a CLI and GitHub Action for validating SKILL.md packages, generating release previews and quotes, and publishing immutable name@version records through the HOL Registry Broker. Pull requests can run local validation without broker credentials. Actual on-chain publishing consumes broker credits and requires authentication, with OIDC trusted publishing available only when the broker deployment supports it.

asta-skill is an optional instruction layer for Ai2’s Asta MCP server. It maps requests for paper search, identifier lookup, authors, citation traversal, batch queries, or full-text snippets to appropriate tool calls with safer defaults and workflow guidance. Access still requires the Asta MCP server and an API key; the tools work without installing the skill.

qapyq is a desktop media curator for preparing large image and video datasets used in LoRA and diffusion workflows. It combines browsing, filtering, caption and tag editing, cropping, scaling, masking, statistics, and batch operations, with optional local or SSH-based model inference. Users can install only the graphical and media-processing components when AI assistance is unnecessary. It requires Python 3.10 or later, and video export additionally depends on FFmpeg.
