This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
perplexity-research from garrytan/gbrain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add garrytan/gbrain/perplexity-research@v0.1.0Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

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).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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 | …

How to install
mdr add garrytan/gbrain/perplexity-research@sha256:2ea626055d28e6b0The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
