YouTube channel assistant: lets agents upload videos, edit titles, descriptions and thumbnails, and manage playlists, captions, comments and live streams; also works as a CLI. Requires enabling the YouTube Data API in Google Cloud and creating OAuth credentials; daily API quotas apply.

The five-agent PaperOrchestra pipeline (outline, figures, literature review, section writing, polishing) as skills: turns research ideas, experiment logs and a conference template into a LaTeX paper and checks citations via Semantic Scholar. Needs Python; verify the draft yourself.

Applies the concrete rules from Refactoring UI to design and fix interfaces: pick spacing, type, color and shadow values from fixed scales, build hierarchy with weight and color rather than size, and create depth with emulated light. Useful when a UI looks amateur, cluttered or off.

Official SonarSource server: connects to SonarQube Server or Cloud so agents can query code issues, quality gates, security hotspots and dependency risks, and analyze file contents directly. Needs a SonarQube token; Docker is the recommended way to run it.

Official Firecrawl skill: drives the Firecrawl CLI to search, scrape, map site URLs, batch-crawl, interact with pages and monitor changes, returning LLM-ready Markdown. Search and scrape have a rate-limited free tier; crawling and monitoring need an account or self-hosted instance.

Firecrawl's official CLI: scrape, search, map and crawl sites and interact with pages in a browser from the terminal, with Markdown output; can also install companion skills for coding agents. Needs a Firecrawl account or API key, or point it at a self-hosted instance.

Lets Claude Code, Cursor and others read and edit Figma designs via a plugin bridge: batch-change colors and fonts, check contrast, generate component code. Free Figma accounts work. Needs Node.js, Figma Desktop, the local WebSocket server running and the plugin imported.

Turns a prompt or still image into a looping animated icon with real transparency, output as animated WebP. It generates one still with GPT Image or Nano Banana, waits for approval, animates it via Seedance on OpenRouter, then mattes and encodes it. Needs Python, ffmpeg and paid API keys.

Two prompt skills: video writes storyboard-style prompts for Seedance, Kling, Veo and more like a director, writer and editor; image writes art-director prompts for Nano Banana and GPT Image, recommending a model per task. Prompts only, generate on the platforms; no API key.

Uses an LLM to translate SRT, ASS and VTT subtitles into any language in batches, convert formats and transcribe audio or video. Install the CLI from source (Python 3.10+); needs an API key (e.g. OpenRouter) or a local model, and subtitles go to that provider.

Turns a conversation into an album production workflow: concept, research, lyrics and pronunciation checks, Suno-style prompts, mastering, promo videos and social copy. You generate songs in Suno yourself; needs Python 3.11+ and ffmpeg, and the author recommends a Claude Max plan.

Manage Postgres databases on Neon in natural language: create projects and branches, run SQL, and use branches for migrations and query tuning. Remote server hosted by Neon with OAuth or API key auth and a read-only mode; Neon recommends it for development only.

Generates flowcharts, sequence diagrams, class diagrams and other charts from Mermaid syntax with configurable theme and background, exporting SVG or PNG files or a mermaid.ink share link. Validates syntax so the model can fix errors over several turns.

Redis's official MCP server: read and write strings, hashes, lists, streams, JSON and other data structures in natural language, with vector indexing and search and pub/sub. Bring your own Redis instance; runs via uvx.

Lets agents deploy a local folder or file contents straight to Google Cloud Run, list services and view their details and logs, and list or create GCP projects. Maintained by Google; sign in with gcloud and set up Application Default Credentials first.

Shopify's official agent plugin: searches Shopify docs and API schemas, validates GraphQL, Liquid and UI extension code, and can manage stores through the Shopify CLI. Sends usage telemetry by default; it can be turned off.

Official Docker skills: containerize projects, optimize and harden Dockerfile builds, orchestrate with Compose, use Docker Sandboxes and Docker Agent, with confirmation guardrails before deletes and other destructive actions.

Railway's official CLI: deploy with railway up and manage infrastructure config, with token auth for non-interactive CI runs. The installer can set up the Railway skill and MCP for Claude Code, Codex and others in one step. Needs a Railway account.

Turns Strunk's The Elements of Style (1918) into a writing skill so agents write docs, commit messages and error messages clearly and concisely. The full text (about 12k tokens) loads only when needed. By the author of Superpowers.

SEO CLI and MCP server for agents: crawls your site for technical issues, uses Search Console data to rank fixes, and compares before and after. Needs Node.js 22+ and Google sign-in; keyword and competitor research needs paid data (DataForSEO, Semrush or Ahrefs).

Read and write Figma from the terminal with commands or JSX: create frames and components, insert Iconify icons, set layout, and export nodes as JSX or Storybook; can also run as an MCP server. Needs Figma Desktop; version 126+ requires daemon --pipe mode.

Chroma's official MCP: lets agents create and manage collections, add documents, and retrieve them with vector search, full-text search and metadata filters. Connects to in-memory or local persistent stores, self-hosted instances or Chroma Cloud.

Eight workflow skills for designers prototyping with AI: requirements interviews, briefs, information architecture, design tokens, task breakdown, UI in a chosen aesthetic and design review, chained by design-flow. Outputs go to .design in the project. For Claude Code, Cursor or Codex.

Fetches captions and transcripts for YouTube videos and Shorts, with language selection and fallback, optional timestamps and sponsor segments filtered by default. No API key for transcripts; the optional visual analysis tool needs a TwelveLabs API key and a direct video URL.
