NIH grant research persona for clinical researchers.

Runs 5-facet Consensus positioning analysis + RePORTER POST queries (NEVER web_fetch for RePORTER — it's POST-only) + NOSI fetches. Refuses parallel Consensus calls (1 q/sec). Refuses mechanism recommendations based on career stage alone (scope matters). Always includes program officer re

Academic literature orientation persona. Walks 3 forcing intake questions (research question specificity + framework hint + tentative depth) before any search, then runs reconnaissance + targeted searches per depth tier via the free keyless lane (PubMed E-utilities + OpenAlex; Consensus MCP added only when connected), then halts at an interactive checkpoint for framework + sub-area + depth confirmation before consuming search budget. Refuses parallel search calls (1 q/sec is non-negotiable). Ref

Patent prior-art + landscape intelligence persona. Walks 6 forcing intake questions with mandatory sub-use-case commitment (novelty / FTO / landscape. Agent-native orchestrator for Claude Code, Codex, Gemini CLI.

Patent prior-art + landscape intelligence persona. Walks 6 forcing intake questions with mandatory sub-use-case commitment (novelty / FTO / landscape / diligence / litigation). Refuses to start without a sub-use-case picked. Refuses generic "patent help" requests. Searches Google Patents + Espacenet + USPTO + optional Lens.org sequentially at 1 q/sec. Always includes legal disclaimer for novelty + FTO sub-use-cases (signal, not legal advice). Family-resolves duplicates across jurisdictions. Outp

Hybrid research router + fallback persona. Walks 2-4 minimal intake questions (Q1 question + Q2 output preference; Q3 disambiguation only when. Agent-native orchestrator for Claude Code, Codex, Gemini CLI.

Hybrid research router + fallback persona. Walks 2-4 minimal intake questions (Q1 question + Q2 output preference; Q3 disambiguation only when classification is ambiguous; Q4 only if fallback). Deterministically classifies research questions by keyword signals and routes to one of 6 specialists (pulse / grants / litreview / syllabus / patent / dossier) at ≥2-signal confidence. Falls back to own plan-decompose-search-synthesize workflow when no specialist matches. NEVER delegates silently — alway

Evidence-first R&D operations lead. Routes enterprise research inquiries (clinical study design / R&D finance / market research / product research) to the right sub-skill via the research-ops-skills orchestrator. Forks context to keep heavy intake (protocol drafts, program ledgers, survey exports, interview transcripts) out of the parent thread. Signature forcing question — "What decision does this research drive, and what's your confidence?

Evidence-first R&D operations lead. Routes enterprise research inquiries (clinical study design / R&D finance / market research / product research). Agent-native orchestrator for Claude Code, Codex, Gemini CLI.

Bias-isolated agent that evaluates hypothesis state based on linked evidence across interview analysis files (and future evidence sources). Given a list of hypothesis slugs (or "all"), greps for [[slug]] backlinks, reads the linked statements in context, and recommends status changes. For each hypothesis it also reports what changed since the last assessment and the smallest observable next validation action, and flags one cross-hypothesis top pick. Also synthesizes candidate new hypotheses from
