Tools

The Docling project's official MCP: converts PDF, Word, PowerPoint and more into structured documents with layout and table detection and OCR for scans, and lets agents build new documents paragraph by paragraph and export Markdown. Local mode needs Python and uv, or use your own Docling Serve.

Unbabel's machine-translation quality metric: comet-score rates translations per sentence and overall, XCOMET marks error spans and severity, and CometKiwi works without a reference. Good for spot-checking MT. Needs Python 3.8+; models download from Hugging Face, some need a license; GPU helps.

Rewrites a paper for a target journal: give it 5-8 papers from that journal (plus optional field or lab examples), it builds an editable style guide for your manuscript, then rewrites section by section to the journal's conventions with a change log. PDF input needs a converter such as MinerU.

Shopify's official CLI: scaffold, develop locally and deploy Shopify apps, extensions, Functions and themes, and build and host Hydrogen custom storefronts. Requires Node.js.

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.

dbt Labs' official plugin marketplace with dbt and dbt-migration plugins: write models and unit tests, build semantic-layer metrics, govern with dbt Mesh, debug failed jobs, and handle version upgrades and cross-platform migrations. Most skills need an existing dbt project.

dbt Labs' official skills: write and edit dbt models, add unit tests and docs, set up the MetricFlow semantic layer, debug failed jobs, and handle dbt version upgrades and cross-platform migrations. Most skills need dbt installed and an existing project.

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.

Lets agents work in Photoshop, Premiere, InDesign, Illustrator and After Effects through UXP/CEP plugins and a local proxy: edit layers, lay out pages and cut timelines. A proof of concept, not made by Adobe; install from source.

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.

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.

Helps agents write geospatial SQL for PostGIS, DuckDB, BigQuery and Snowflake: inspect schemas and keep query costs in check, then render results as interactive maps to review and correct. Needs Python and your own database or warehouse; maps use Dekart, which can run locally in Docker.

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 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.
