perplexity-research skillA
perplexity-research is agent-read markdown (skill) from garrytan/gbrain: 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)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# perplexity-research — Brain-Augmented Web Research > **Convention:** see [conventions/quality.md](../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](../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 | …
