Core Data Agent Skill gives compatible AI coding tools focused guidance for Apple’s persistence framework. Its decision tree routes the agent to references on model configuration, fetch optimization, batch operations, saving, schema migration, performance, persistent history, CloudKit integration, and project audits. Developers can install it through the standard skills command, as a Claude Code plugin, or by manually linking the folder. It is intended for Swift projects needing practical Core Data diagnosis and implementation advice without imposing a particular application architecture.

HackDesk is a desktop client that wraps hackmd.io in a lightweight Tauri application, giving HackMD users a dedicated window for their existing collaborative Markdown workflow. The stable macOS build can be installed through Homebrew, but it is currently unsigned and may require manual approval on first launch. A parallel Electron beta is developing a more native workspace, search, settings, and note-management experience while the Tauri version remains the stable path.

Gollum Voice wraps an agent’s replies in a Gollum/Sméagol persona while leaving code, commands, paths, numbers, and factual answers intact. It offers lite, full, and ultra intensity plus friendly, sharp, and mixed joke settings, and stays off until explicitly enabled. A 575-line joke bank across 32 categories supplies variety; the project is entertainment rather than a reasoning upgrade.

CLI Trainer guides a no-code fine-tuning run on Baidu AI Studio. It lists allowed models, checks dataset formats, recommends framework-specific hyperparameters, submits the job, polls its status, opens TensorBoard when available, and summarizes loss and artifact usability. It supports ERNIE through PaddleFormers and several open models through LlamaFactory, but requires Python, requests, an AI Studio access token, and network access to the training service.

honestweek turns a completed week of local AI coding sessions into a shareable work report that includes work not yet visible in commits. It re-checks every git-verifiable claim against commits or aborts, labels each item as shipped, in progress, or designed but unproven, and attaches a source pointer. The draft remains private for the user to review and publish; there is no telemetry or automatic publishing.

Biomedical Research Analyst gives Claude a disciplined workflow for verifying a public dataset against the research question, choosing suitable statistics, and keeping data-derived findings separate from cited literature. Before delivery, it requires specific claims, pathway-gene assignments, thresholds, and inferential language to be checked against the underlying results. Included Python components support GEO parsing, differential expression, figures, and PPTX assembly, but the outputs remain hypothesis-generating unless the study design supports stronger conclusions.

expo56-skill packages Expo SDK 56 guidance into twenty topic-based documents that Claude Code loads as needed. It supports new app development and SDK 55 migrations across routing, native modules, file handling, media, authentication, tooling, and EAS workflows, helping avoid outdated or invented APIs. The material is a May 22, 2026 beta snapshot rather than a live mirror, so release-critical versions and interfaces still require verification against official Expo sources.

This repository bundles two reusable agent skills rather than a single application. Blueprinter generates technical diagrams in a flat engineering-blueprint style with HTML and CSS. Brief initializes and operates a React/Vite report site, turns source material such as articles or codebase analysis into standalone reports, publishes them into the site, and starts a local preview. It is useful for extending an existing agent with repeatable diagramming and report-publishing workflows.

g3 is a Rust terminal agent with file, shell, desktop-control, code-search, and TODO tools. It connects to Anthropic, Databricks, or local llama.cpp models with Metal acceleration on macOS, monitors context usage, thins large tool results, and retries recoverable errors. Local models support offline or privacy-focused work, but the project notes weaker results on complex tasks and marks computer control as experimental.

This skill connects Claude Code, Codex CLI, Gemini CLI, and other skill-aware assistants to the VAP Media API. Users can request image, video, or music generation as well as media editing or enhancement, then receive the resulting media URL; authenticated use requires a VAP product key.

paper-repo-builder scaffolds a taxonomy and candidate list from a topic, seed paper, or existing repository, deduplicates candidates, verifies arXiv and DOI metadata, and checks downloaded PDFs against their citations. It fetches open-access papers in parallel and can use an isolated, logged-in Chrome session through Playwright only for papers your institution already permits, then generates a classified README and optional Zotero collections. The full workflow requires Python, requests, pdftotext, Playwright, and Chrome.

Layout Discipline gives Claude and other agents a fixed set of typography, 4-pixel spacing, alignment, card, color-token, and vertical-rhythm rules for generated web pages and HTML demos. A zero-dependency checker can flag off-grid spacing, unsupported font sizes, and raw hex colors by line before delivery. Because it scans text rather than parsing a full CSS syntax tree, hex values in documentation can produce false positives.

This skill processes a book into an optional Chinese translation, chapter-by-chapter reading notes, and a cross-chapter theme index stored in an Obsidian vault. It preserves chapter links and can export the translation as EPUB, PDF, DOCX, or Markdown; Python dependencies are required, while full-format export also needs Calibre and Pandoc.

icp-market-research starts with a won-customer CSV, enriches each company, tags triggers such as hiring, funding, executive changes, expansion, or launches, and ranks the patterns they share. It returns an ICP and anti-ICP, an enriched customer table, personalized opener signals, and reusable list filters. It uses no API key beyond normal Claude usage, but its conclusions depend on the customer data you provide.

remotion-ad-video-skill structures product ads as React and Remotion compositions, with scene-by-scene exports, synthesized sound effects, and a rendered-frame review loop. It detects BPM and quantizes scene durations to the track’s beat grid, then can switch copy, currency, and RTL/LTR layout through one LANG setting without changing timing. The setup requires Remotion, Python with numpy and scipy, and ffmpeg.

EchoCoding connects sound effects, text-to-speech, speech recognition, voice prompts, and ambient audio to Claude Code, Cursor, Windsurf, Codex CLI, and Gemini CLI through hooks, MCP, and command-line tools. Its installer starts a local daemon without requiring model downloads or API-key setup, while microphone features still depend on local audio permissions.

Use this agent skill to audit and redesign contributor programs for open-source communities, DevRel teams, and developer ecosystems. It helps map visible and invisible labor, test whether recognition is proportional, identify concentrated workloads and burnout signals, and show contributors their impact. The framework also connects community activity to outcomes leadership cares about, so recognition and sustainability are treated as one system.

Turn a one-line product brief into a browser-ready static HTML and Tailwind page. The skill anchors each build to one real reference site, then chooses a page archetype, typography, color, and micro-grammar so the result does not default to the same generic layout. It can hand-build dashboards, tables, charts, and code-like UI elements.
