Skill pack for YouTube creators with 14 subcommands: channel audits, video SEO, retention-focused scripts, hooks, thumbnail briefs, content calendars, and Shorts and cross-platform repurposing. Works with data you provide; add a YouTube API key or DataForSEO for live data.

A research plugin for Claude Code: commands like /omp:survey, /omp:experiment and /omp:write chain literature review, topic selection, experiments, writing and self-review, with 5 specialized agents and 34 research skills that remember project progress across sessions. Experiments lean toward ML.

21 English writing rules (12 from The Elements of Style, Orwell, Pinker and other classics, 9 from observed LLM habits) for clearer, leaner papers, grant proposals, design docs and documentation. Expository English only; not for fiction or marketing copy.

Open-source marketing toolkit with 78 skills for SEO audits, blog and landing-page copy, email sequences, social posting, ad campaigns and competitor analysis. Basic use needs no keys; pulling data from Semrush, GA4 or HubSpot, or publishing automatically, needs the matching API keys.

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.

Economics writing skill built on 50+ guides (Cochrane, McCloskey and others): shapes abstracts, introductions and conclusions by paper type and 13 identification strategies such as DiD, IV and RDD, simulates three referee scores and flags citations to verify.

Two skills for before and after peer review: review-revision checks a manuscript as a senior reviewer would and plans section-by-section revisions; rebuttal-response triages reviewer comments, plans extra evidence and drafts point-by-point replies. Takes PDF, LaTeX, Word or Markdown.

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.

One server for Google Docs, Sheets, Drive, Gmail and Calendar: draft and format documents, handle comments, organize sheets and charts, triage email and schedule events. Create an OAuth client in Google Cloud and run the auth command once; needs Node.js.

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.

Compares two versions of a LaTeX manuscript and produces a .tex that marks additions and deletions in color and strikethrough; compile it for a tracked-changes PDF to show reviewers, or diff versions from Git history. Ships with TeX Live and MiKTeX; needs Perl.

Searches about 30 biomedical sources, including PubMed, ClinicalTrials.gov, ClinVar and OncoKB, with one command syntax, covering literature, clinical trials, genetic variants, drugs and pathways. Ships as both a CLI and an MCP server.

Turns web pages, long PDFs, Word files, images or code into tutor-style study notes: Markdown notes plus searchable HTML knowledge cards with concept breakdowns and mind maps. Needs Python 3.8+, plus Chrome for some sites; the optional tutor chat needs an OpenAI-compatible API key.

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.

14 social media skills: audience and content pillars, posting calendars, platform-specific posts, threads, carousel scripts and captions, and analytics on what drives follower growth. For LinkedIn, X, Threads, Instagram and more; connect the BlackTwist MCP to schedule posts directly.

Anthropic's official life sciences plugin marketplace: install MCP plugins such as PubMed, BioRender, Synapse, ChEMBL and 10x Genomics, plus research skills for single-cell RNA QC, Nextflow pipelines and scvi-tools. Some data sources need an account or subscription.

Anthropic's official research skill built on Fischbach and Walsh's problem-selection framework (Cell): a conversational guide to refining project ideas, assessing risk and success criteria, unblocking stalled research and choosing directions. No setup or account needed.

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.

Plugin from Wiley in Anthropic's life sciences marketplace: connects the Scholar Gateway remote MCP for semantic search across Wiley's peer-reviewed journals, with answers carrying checkable citations and DOI links. Good for literature reviews. Needs a free Scholar Gateway account.

PubMed plugin from Anthropic's life sciences marketplace: connects to the US National Library of Medicine's remote MCP to search biomedical literature and research papers. No account needed.

Official BioRender plugin in Anthropic's life sciences marketplace: connects Claude Code to BioRender's scientific icons, templates and figures to find assets and make paper figures, lecture slides and talk graphics. Needs a free BioRender account; authorize it in /plugin after installing.
