SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Web research often produces unverified, outdated, or marketing-driven claims presented as facts. This Skill enforces a rigorous pipeline where every load-bearing claim must survive adversarial verification before appearing in the final report, eliminating the primary failure mode of trusting unverified web content. ## Core Features & Use Cases - Structured Research Pipeline: Decomposes a question into 3-6 complementary search angles, fans out web searches, fetches up to 15 deduplicated sources, and extracts falsifiable claims with supporting quotes. - Adversarial Verification: Runs 3 independent skeptical checks per claim on the top 25 claims, killing any claim with 2 or more refutations and tracking the vote tally. - Confidence-Ranked Reporting: Produces a Markdown report with an executive summary, findings rated high/medium/low confidence, a refuted-claims section for transparency, caveats, open questions, and a source quality table. - Use Case: An analyst performing due diligence on a vendor asks for a fact-checked report; the Skill searches multiple angles, verifies each vendor claim against independent sources, and delivers a cited report distinguishing what the product does from what the vendor claims. ## Quick Start Ask the agent to do deep research on your question, for example: run deep research on whether solid-state batteries will reach mass-market EVs by 2030 and give me a fact-checked report.

Frequently Asked Questions about Deep Research

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I get a fact-checked research report on any topic?▼

Ask for deep research on your question. The skill decomposes it into 3-6 search angles, fetches up to 15 sources, extracts falsifiable claims, adversarially verifies the top 25 claims, and synthesizes a confidence-ranked cited report.

How does adversarial claim verification work in deep research?▼

Each claim gets 3 independent skeptical checks: quote support, contradicting evidence from web search, source quality, currency, and marketing bias. A claim survives with fewer than 2 refutations; 2 or more refutations kill it, and the vote is tracked per claim.

What are the limits on sources and claims during deep research?▼

Default budgets cap the run at 5 search angles, 15 fetched unique sources after URL deduplication, 2-5 claims per source, and 25 verified claims. Budgets scale up only when the user explicitly asks for exhaustive coverage.

What happens if every claim fails verification?▼

The skill reports the research as inconclusive and explains why, distinguishing low-quality sources from genuine contradiction. It never presents killed or unverified claims as findings, so an inconclusive result is a valid outcome.

When should I ask clarifying questions before starting deep research?▼

Ask 2-3 clarifying questions when the question is underspecified, such as a purchase question without budget, use case, or region. Narrowing scope first prevents wasted search budget on irrelevant angles.
