Decision-grade entity research. Produces a hypothesis-tested dossier on a specific company, person, nonprofit, or government org — built around hypothesis-testing rather than encyclopedic summary.

Non-generic by design

The skill refuses to be "tell me about Microsoft". Every invocation forces the user to expose their hypothesis upfront (Q4 — mandatory), so the dossier tests it rather than confirms it.

❌ Generic ask	✅ Decision-grade ask
"Tell me about Microsoft."	"I'm pitching Microsoft Tuesday. My hypothesis is they're consolidating AI spend on Foundry. Validate or disprove, and give me 3 conversation hooks tied to what you find."

The forcing Q4 is the non-generic anchor. Without it, the skill produces a Wikipedia summary.

Sibling skill relationship

Part of the research pack (sibling of pulse, litreview, grants). Shares Agent Integrity Rules (1 q/sec, source discipline, three-count tracking, retry-once-after-3s, stop-after-3-consecutive-failures).

Different from siblings:

Hypothesis-testing discipline — ≥30% of search budget allocated to disconfirming evidence
Source-tier discipline — every flag tagged primary / secondary / tertiary
Subject-type routing — different source matrix for person / company / nonprofit / gov
Verdict in Executive Summary: SUPPORTED / PARTIALLY SUPPORTED / DISPROVEN / INCONCLUSIVE
Uses WebSearch + WebFetch + free APIs (not Consensus)
