Apple Bento Grid is an agent skill that generates self-contained HTML presentations from stats, achievements, launch data, or year-in-review content. The workflow can choose a layout, light or dark theme, chart and card types, and output orientation. It supports horizontal, square, and vertical compositions suited to project showcases, dashboards, portfolios, and social posts.

OysterWorkflow records screen states, OCR text, clicks, keystrokes, windows, and optional narration on macOS or Windows, then identifies meaningful work patterns and turns them into reviewable OpenClaw skill artifacts with retries, decisions, and completion checks. Users inspect the captured evidence and generated steps before installing anything into an agent. The app requires sensitive recording and accessibility permissions, currently supports Apple Silicon macOS and Windows x64, and has limited Chinese input and speech support on Windows.

ghealth wraps Google Health API v4 in a single Go binary for developers and agents. It supports 40 verified data types, including steps, heart rate, sleep, exercise, weight, SpO2, and nutrition, with simplified JSON, deterministic exit codes, dry runs, and progressive schema discovery. Initial setup requires a Google Cloud project and OAuth credentials; stored access and refresh tokens are protected by file permissions but remain plaintext JSON on disk.

WG Tunnel is a desktop client for WireGuard and AmneziaWG configurations. Users can import, edit, export, sort, and monitor tunnels, while an independent lockdown mode blocks traffic when protection should remain enforced and can restore the previous tunnel at startup. The tunnel itself runs as a system service rather than depending on the graphical application, and configuration data is encrypted with system keychain integration. Current releases support Windows and Linux; Windows requires version 10.0.19041.0 or newer, while macOS support is still planned.

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.

This Claude Code collection supports computational designers across architecture, engineering, and construction. Eighteen connected modules cover parametric and generative design, geometry, structures, environmental analysis, facades, fabrication, BIM, interoperability, optimization, meshes, automation, and AEC machine learning. A foundation skill routes requests and loads references on demand. Seven Python calculators handle geometry, structural checks, solar conditions, panels, mesh quality, materials, embodied carbon, fabrication time, and cost.

UI Craft installs a design-engineering system into Claude Code, Cursor, Codex, Gemini, OpenCode, and related coding tools. Its CLI can wire in the main skill, focused commands, design and accessibility reviewers, MCP quality gates, and design memory, with backups and rollback around configuration changes. The project separates judgment from deterministic checks: skills and reviewers handle hierarchy and composition, while MCP tools scan for generic AI styling, token drift, and acceptance requirements. It is a workflow layer, not another component library.

hands-on-deck gives AI agents one CLI, deck.py, for inspecting, editing, creating, and verifying PowerPoint files. Agents can read shapes and formatting, change text, styles, themes, images, geometry, notes, and slide settings, or create new slides through the same writer. Changes arrive as atomic JSON patches: every operation is prevalidated, errors report actionable slide details, and a rejected patch leaves the deck untouched. HTML and CSS can be used as a layout-measurement source, then compiled into patches that share the same lint, render, diff, and repair workflow.

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.

skill-check validates SKILL.md structure, frontmatter, description quality, body limits, and local references, then reports clear diagnostics and a quality score. It can apply deterministic safe fixes, scan local paths or GitHub repositories, and export JSON, SARIF, HTML, or GitHub annotations. Security scanning is enabled by default in the CLI and may install scanner dependencies unless automatic installs are explicitly disabled.

VirusTotal for macOS is an unofficial native client for submitting files, batches, and URLs to VirusTotal, then reviewing reports, scan history, and API quota usage. It requires your own VirusTotal public API key and keeps its application logs locally. The app targets macOS 14 or later, and its release build may trigger a security warning because the developer does not provide Apple notarization.

Extract the archive and launch Portable Hermes Agent on Windows without admin rights, a system Python installation, or Docker. Its GUI and CLI can use cloud providers or local models through LM Studio, with tools for automation, custom workflows, runtime tool creation, and optional speech, music, or ComfyUI extensions. It supports Windows 10 and 11 only, and local model use generally requires an NVIDIA GPU with at least 8 GB of VRAM.

Graph of Skills indexes a directory of SKILL.md files into an offline skill graph, then returns a small ranked bundle for each task together with prerequisites and related capabilities. It can be used through its CLI, an MCP server, or Claude Code integration, with either prebuilt workspaces or an index built from your own library.

GuitarTuner listens through the microphone, identifies the played note, and sounds a cue when the instrument is in tune. It is designed for guitar but works as a chromatic tuner for other instruments, with an adjustable reference frequency. The prebuilt macOS release is Intel-only; Windows users need to install the Python dependencies and run the program from the command line.

Usage Monitor for Claude is a portable Windows tray application that displays current session, weekly, and newly detected quota types through configurable bars and a detail popup. It reuses the OAuth credentials from an existing Claude Code login, so no separate API key entry is required, and shows reset countdowns or stale-data warnings. Claude Code must be installed and signed in; the monitor operates read-only and does not write local files.

Maya is a native macOS editor for placing iPhone screen recordings inside device mockups, a configurable generic frame, or a frameless canvas. Users can choose common social and widescreen aspect ratios, adjust the presentation, add cinematic zoom moments, and export polished clips for marketing, social posts, or in-app tutorials. Built-in device choices currently focus on selected Pro iPhone models, and the app requires macOS 26.3 or later.

tufte-data-viz is an agent skill that applies Edward Tufte's high-data-ink principles across Recharts, ECharts, Chart.js, matplotlib, Plotly, and D3 or SVG. It removes nonessential gridlines and decoration, favors direct labels, and adds screen-oriented guidance for accessibility, responsiveness, and interaction. The skill is deliberately opinionated: it may reject pie charts, dual axes, legends, or decorative styling, so it suits users who want a consistent visual philosophy rather than unrestricted art direction.

Theorist keeps a THEORY.MD at the repository root that explains the problem thesis, current system model, strategy, important discoveries, and open uncertainties. The Codex- and Claude-compatible skill rewrites the document holistically when understanding changes instead of appending a task plan, changelog, or status log. It provides a lightweight strategic memory for long-running engineering work.
