What problem does it solve? Ad-hoc web research produces shallow, unverifiable answers with no audit trail, and one-off reports cannot support long-term expertise on a strategic topic. ## Core Features & Use Cases - Recursive exploration until saturation: Runs up to 8 iterations of planner, three parallel researchers, fact-checker, and critic agents, stopping when no new verified facts appear. - Full knowledge base vault: Produces a 10,000+ word main report plus executive summary, glossary, timeline, key players, actionable playbooks, steel-manned counter-arguments, annotated bibliography of 150+ sources, and PDF/EPUB exports. - Cross-model verification: Uses Codex CLI, Perplexity, and Exa deep-researcher channels alongside Tavily/Firecrawl to fact-check claims, with three independent peer-review passes. - Use Case: Ask to become an expert on a technology domain; the skill runs the L1–L4 research ladder as a foundation, then iterates until saturation and syncs the resulting vault to long-term memory. ## Quick Start Run /ultra-research on the topic you want to master and confirm the budget prompt to generate a complete knowledge base.
