research-lookup
Look up current research information using Perplexity Sonar Pro Search or Sonar Reasoning Pro models through OpenRouter. Automatically selects the best model based on query complexity. Search academic papers, recent studies, technical documentation, and general research information with citations.

Same command for any agent — swap --agent for codex, cursor, copilot.

What it does
This skill enables real-time research information lookup using Perplexity's Sonar models through OpenRouter. It intelligently selects between Sonar Pro Search (fast) and Sonar Reasoning Pro (deep analytical reasoning) based on query complexity. It provides access to current academic literature, recent studies, technical documentation, and general research information with proper citations and source attribution.
How it works
The skill determines query complexity and, accordingly, uses one of two models:
- Sonar Pro Search for straightforward lookups (fast, lower cost).
- Sonar Reasoning Pro for complex analytical queries (thorough, higher cost). It integrates with OpenRouter API to perform academic/scholarly searches, focusing on peer-reviewed sources, and returns citations with complete bibliographic information and stable links. It includes guidance for generating scientific schematics when creating documents, and it supports queries related to academic papers, protocols, statistics, and expert opinions. The automatic model selection uses keywords and scoring to decide when to switch to the deeper reasoning model, with an option to override via force_model in commands or code.
When to use it
Use this skill for:
- Current Research Information: Latest studies, papers, and findings
- Literature Verification: Check facts against current research
- Background Research: Gather context and supporting evidence
- Citation Sources: Find relevant papers to cite
- Technical Documentation: Look up specifications or methodologies
- Recent Developments: Stay updated with trends
- Statistical Data: Find recent statistics or survey results
- Expert Opinions: Access insights from recent interviews or reviews
What it can touch
It interacts with the OpenRouter API and supports model selection between:
- perplexity/sonar-pro-search
- perplexity/sonar-reasoning-pro-online Response quality emphasizes peer-reviewed sources, reputable institutions, and recent publications, with complete bibliographic information and DOIs or stable URLs when available.
Caveats
Known limitations include information cutoff around 2-3 years prior to present, potential paywall restrictions for full texts, and possible misses of very recent papers not yet indexed. It notes API rate limits, network issues, and the need for well-formed queries. Fallbacks include rephrasing queries or using broader time frames. The skill relies on OpenRouter API keys (OPENROUTER_API_KEY) and sufficient credits.

What does the research-lookup skill do?
Look up current research information using Perplexity Sonar Pro Search or Sonar Reasoning Pro models through OpenRouter. Automatically selects the best model based on query complexity. Search academic papers, recent studies, technical documentation, and general research information with citations.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill research-lookup-k-dense-ai-claude-scientific-sk --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.
