What problem does it solve? Web research often repeats what you already know, wasting time re-reading settled facts. This Skill sends your existing brain context to Perplexity so the web search focuses only on the delta — what is new, changed, or contradictory relative to your knowledge base. ## Core Features & Use Cases - Brain-Augmented Search: Sends existing brain page content as context in the Perplexity prompt so results highlight only new information. - Cited, Structured Output: Writes a research page under research/<slug>.md with sections for new developments, confirming signals, contradictions, recommended brain updates, and citations. - Model & Recency Control: Choose between sonar-pro for deep analysis or sonar for bulk monitoring, and apply recency filters (hour, day, week, month). - Use Case: Run a weekly cron over active deals to pull recent company news, flag changes, and write cited research pages for review. ## Quick Start Ask the agent to run perplexity-research on a company or person to surface new developments the brain does not already cover.
