What problem does it solve? Setting up optional API keys for a research wiki system is confusing — users don't know which keys exist, what each one does, or how to get them. This Skill inspects the current .env state and interactively walks users through configuring each key with clear explanations. ## Core Features & Use Cases - Environment Detection: Reads .env and reports which keys (Semantic Scholar, DeepXiv, Review LLM) are set or missing, plus Python and .venv status. - Guided Key Configuration: Step-by-step flows for each key, including automatic DeepXiv token registration via its API and validation of OpenAI-compatible LLM endpoints. - Safe Writes: Never overwrites existing non-empty values without confirmation and masks key values in output. - Use Case: After a fresh install, run the setup flow to get a free Semantic Scholar key, auto-register a DeepXiv token, and connect a DeepSeek or other OpenAI-compatible review model — then verify everything with a final status check. ## Quick Start Ask the assistant to run the setup flow to check my current .env configuration and help me configure any missing API keys.
