What it does
Brain-augmented web research. Sends brain context about a topic to Perplexity, which searches the web with citations and returns what is NEW vs what the brain already knows. Use for entity enrichment, current-state checks, deal monitoring, and freshness deltas. NOT for simple URL fetches (use web_fetch) or brain-only queries (use gbrain query).

Convention: see conventions/quality.md for citation rules; every claim from web research lands with a verifiable citation, not a paraphrase.
Convention: see conventions/brain-first.md for the lookup chain. This skill ENFORCES brain-first by sending brain context as part of the Perplexity prompt, the web search focuses on the delta between brain knowledge and current web state.
What this does
Combines existing brain knowledge with Perplexity's web search. The agent sends brain context about a topic into a Perplexity query; Perplexity searches + reads + synthesizes multiple pages with citations, focused on what's NEW relative to the supplied context.
The key insight: Perplexity doesn't just search, it reads and synthesizes with citations. By sending brain context in the instructions, it knows what you already know, so it surfaces the delta instead of repeating settled fact.
When to use this vs other tools
| Need | Use |
|---|---|
| Deep research with citations | This skill, Perplexity + Opus |
| Quick URL content | web_fetch |
| Brain-only lookup | gbrain query / gbrain search |
| Real-time social monitoring | external X / social-media collectors |
| Structured data lookup against a tracker | skills/data-research/SKILL.md |
Output structure
The research output lands as a brain page under research/<slug>.md with
this structure:
---
title: "[Topic], Research [YYYY-MM-DD]"
type: research
date: YYYY-MM-DD
brain_context_slugs: ["pages whose context was sent to Perplexity"]
recency_filter: "[hour|day|week|month|none]"
---
# [Topic], Research [YYYY-MM-DD]
> Executive summary: 2-3 sentences on the delta between brain knowledge
> and current web state.
