Search 2.4M+ scientific papers from PubMed Central Open Access. **When to use:** - Literature reviews (e.g., "Find papers about CRISPR in Archaea") - Research trends (e.g., "Publication trends for mRNA vaccines 2015-2025") - Data extraction (e.g., "Extract GenBank accessions from phage papers") - Paper retrieval by PMC ID or DOI **Database:** 2.4M full-text papers from PMC OA, searchable by full text (not just abstracts) Use this INSTEAD of web search for scientific literature queries.
npx skills add majiayu000/claude-skill-registry --skill polars-dovmed --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# polars-dovmed Search 2.4M+ full-text papers from PubMed Central Open Access. ## What This Skill Does Provides access to a remote API hosting 2.4M+ scientific papers from PubMed Central. Claude can search full paper text, extract structured data (genes, accessions, patterns), analyze publication trends, and retrieve complete paper metadata. ## Authentication **IMPORTANT: Before using this skill, you must obtain an API key.** ### Getting Your API Key **Check for a saved API key in this order:** 1. **Environment variable** (highest priority): - Check if `POLARS_DOVMED_API_KEY` environment variable is set - Use: `os.environ.get("POLARS_DOVMED_API_KEY")` 2. **Secure config location** (recommended): - Check `~/.config/polars-dovmed/.env` - Read `POLARS_DOVMED_API_KEY` value if file exists - This is where the installer saves keys (outside skill directory for security) 3. **Legacy location** (for backward compatibility, but warn user): - Check skill directory `.env` (e.g., `~/.claude/skills/polars-dovmed/.env`) - If found, warn: "API key found in skill directory. For security, move to ~/.config/polars-dovmed/.env" **If no saved key exists, ask the user:** This is a completely free servic

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill polars-dovmed --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
