Run deep research / advanced research / "perplexity research" on a topic — multi-step web browsing with citations via Perplexity's Agent API. Use when the user asks for a sourced brief, competitive analysis, competitor research, market research, GTM or landing-page audit, feature comparison, market stack-rank for expansion, investor-memo background, due-diligence brief, "investigate X thoroughly", "research report on Y", "build out [initiative]", or any request that needs multi-step browsing + inline citations. Enforces the GTM deep-research methodology from Growth Unhinged (growthunhinged.com/p/deep-research-for-gtm) — gathers goal + product context + constraints + source preferences, drafts a research plan for approval before spending API credit, budgets against the per-call output ceiling to prevent truncation, and requires a structured report (TL;DR, comparison tables, inline citations, Sources table with primary-source priority, Where-sources-disagree, Confidence & gaps). Default preset — advanced-deep-research (Claude Opus 4.6 + web_search + fetch_url). Requires PERPLEXITY_API_KEY.
