What problem does it solve? Setting up a local research workspace often fails because of missing Python dependencies or unset API keys for scholarly data providers. This Skill checks the research pack tooling and guides you through creating a local .env file without ever exposing secret values. ## Core Features & Use Cases - Tool Verification: Runs help commands for fetchers covering arXiv, Semantic Scholar, OpenAlex, Unpaywall, CORE, DeepXiv, and Wikipedia to confirm each tool works. - API Key Guidance: Reports which optional keys (SEMANTIC_SCHOLAR_API_KEY, OPENALEX_API_KEY, UNPAYWALL_EMAIL, CORE_API_KEY, DEEPXIV_TOKEN) are missing, what each provider offers, and where to register. - Safe .env Management: Creates or updates .env only with values you explicitly provide, preserving existing keys and never printing secrets. - Use Case: After installing the Lumina research pack, run this Skill to confirm all fetchers work and learn that you only need a free Unpaywall email to enable the full PDF resolution ladder. ## Quick Start Ask the assistant to check the research pack tools and tell me which API keys I still need to configure.
