What it does

Restates your question in one sentence and pins down the decision the research must inform (asking clarifying questions if it's vague).
Plans a source mix from a menu: WebSearch for authoritative docs, WebFetch for supplied URLs, the last30days skill for Reddit/X/YouTube/HN chatter, agent-browser for auth-walled or JS-heavy pages, local memory, Notion, and prior research archives — run in parallel where possible.
Separates collection from synthesis: groups findings by theme, surfaces disagreements instead of averaging them, tags confidence high/medium/low, and lists what's missing.
Emits a fixed brief template: TL;DR, key findings with citation markers, contradictions, gaps, recommended next steps, dated source list.
Archives each brief to ~/.config/makerskills/deep-research/archive/ and appends a line to INDEX.md so past work stays searchable.

Who it's for

Sales and BD folks prepping competitor or account research before a call.
Founders and PMs validating a market or hunting positioning angles.
Engineers who need a defensible tech decision (which database, which auth provider).
Anyone doing due diligence on a partner, hire, or podcast guest.

Example uses

"research the B2B SaaS onboarding tool market" → sized market, key players, current sentiment, each claim cited and confidence-rated.
"due diligence on this company before tomorrow's meeting" → official statements plus pricing pages plus community reactions, with conflicting claims flagged.
"Supabase vs Firebase auth — which should we pick?" → docs cross-checked against real user reports, ending with a recommendation and remaining unknowns.
