Produce a rigorous, verified, fully-cited research report on ANY topic by running a disciplined five-stage pipeline: CLARIFY the question, PLAN (an editable research plan), FAN-OUT parallel search subagents, VERIFY every key claim (cross-source + adversarial + cross-model), then SYNTHESIZE a cited report. Use this WHENEVER the user wants real research rather than a quick answer — "research X", "do a deep dive on Y", "write me a report / brief / literature review on Z", "compare A vs B and back it with sources", "what's the state of the art in …", "investigate …", "find evidence for/against …", "give me a market/landscape/competitor analysis", or any question where being wrong is costly and the answer needs citations. Trigger even when the user does not say the word "research" but clearly needs multi-source, fact-checked, cited output. This is the general-topic web-research orchestrator — not the codebase-to-wiki `deep-research` skill. For a fast single-fact lookup, answer directly instead.

Low-risk findings worth noting
"Prefer primary sources" is too blunt to be a universal rule: a primary source can be biased, obsolete, or self-serving, and in some domains a good secondary source (a systematic review, a court's summary) outranks any single primary one. Pick the ladder that fits the topic before FAN-OUT and put it in the shared research brief so every worker applies the same bar.
| Domain | Evidence ladder (prefer higher) | Watch out for |
|---|---|---|
| Medicine / health | Systematic reviews & meta-analyses → large RCTs → small RCTs → cohort/observational → case reports → expert opinion. Regulatory assessments (EFSA/FDA) are strong. | Single small studies overhyped in press; industry-funded trials; healthy-user bias; surrogate endpoints. |
| Science / engineering | Peer-reviewed replications → peer-reviewed primary → preprints (arXiv) → reputable technical blogs → vendor docs. | Preprints ≠ peer-reviewed; irreproducible single results; benchmarks run by the seller. |
| Companies / markets | Regulatory filings (10-K/S-1) → audited financials → reputable financial press → analyst notes → company blog/PR. | PR framing; TAM inflation; paid "research"; numbers with no defined methodology. |
| Law / policy | Statutes & the ruling text itself → official regulator guidance → law-firm analysis → news. Jurisdiction + currentness are decisive. | Outdated/overturned rulings; wrong jurisdiction; secondary summaries that drop nuance. Not legal advice. |
| Software / tech choice | Official docs & source code → neutral benchmarks (methodology published) → named production case studies → practitioner posts → vendor benchmarks. | Vendor-vs-vendor benchmarks (label the affiliation); version drift; benchmark ≠ your workload. |
| News / current events | Primary documents & on-record statements → multiple independent outlets → single outlet → social media. | Single-source scoops; syndication counted as corroboration; anonymous claims. |
When a topic spans domains, apply each domain's ladder to its part.
For these, tighten everything and be explicit about limits:
Being honest about the boundary is part of trustworthiness. This skill is an LLM instruction set, not a deterministic data pipeline, so it deliberately does not:
verify_citations.py checks report ↔ ledger
consistency (every citation maps to a ledger row with a real passage); it cannot see the original
HTTP calls. The passage-in-ledger discipline is the mitigation, not a guarantee.Naming these in the report's caveats section is expected, not a weakness.
