Evidence Insight

biomarker-landscape-scanner

Scans the biomarker landscape of a disease area by type, use case, validation status, and maturity level. Polished: Step 1.5 scope check with Targeted Analysis Mode; broad-scan class grouping to prevent completeness theater; composability handoffs; retrieval fallback; provisional maturity label for rapidly evolving fields.

Scientific IntegrityPASS
Hard rules 13-14, 17 explicitly prohibit fabricating references, PMIDs, DOIs, and conversion of vague field memory to citation-like claims. Hard rule 17 requires labeling unverified claims as evidence-limited. Section J (References) has citation integrity requirements.
Practice BoundariesPASS
Explicit out-of-scope redirect for patient-specific lab interpretation. Field-level evidence map, not clinical decision tool. Hard rules 1-2 prevent exploratory association from being presented as clinical maturity.
Methodological GroundPASS
Five-tier maturity system with explicit minimum evidence standards and upgrade/downgrade rules is methodologically rigorous. Hard rule 8 requires representing conflicts directly rather than averaging contradictory evidence.

MSI/MMR Tier 3-4 for NSCLC. Transcriptomic signatures Tier 1-2. Section E identifies PD-L1 clone conflicts. Validation level vs maturity tier correctly distinguished.

Pancreatic cancer early detection biomarkers — CA19-9, liquid biopsy ctDNA, protein panels

CA19-9 correctly assigned Tier 3 (widely used but known sensitivity/specificity limitations for early detection). Liquid biopsy ctDNA Tier 1-2 (low sensitivity for early-stage PDAC). Various protein panel proposals Tier 1. Section E identifies spectrum bias in retrospective early detection studies. Hard rule 7 applied to prevent AUROC overclaiming.

Sepsis prognosis and risk stratification biomarkers — conflicting evidence, heterogeneous population

Hard rule 8 applied throughout: endpoint heterogeneity (28-day mortality vs organ failure vs ICU length of stay) identified as main conflict source. PCT and lactate assigned Tier 3-4; IL-6, presepsin, suPAR Tier 2-3. Conflicts represented directly — no false neutralizing. Section E is the most detailed section for this input.

Alzheimer's disease blood-based biomarkers — p-tau217, Aβ42/40, NfL by use case and maturity

Rapidly evolving field. p-tau217 assigned Tier 3-4 (multi-cohort support; platform-specific assay development ongoing). Plasma Aβ42/40 Tier 3 (validated but platform sensitivity variation). NfL Tier 3 (monitoring; non-specific). Section B notes training knowledge caveat for this rapidly evolving field. Diagnostic vs staging vs monitoring use cases separated.

All prostate cancer biomarkers across early, advanced, and treatment-resistant settings

Input is extremely broad. Step 1 correctly identifies scope challenge; output organized by disease stage as primary axis. PSA/PSA density assigned Tier 5 (routine clinical embedding). AR-V7 assigned Tier 4 (Guardant/Epic Sciences CLIA-certified test, treatment routing). Novel liquid biopsy Tier 1-2. However: Section C produces a long biomarker inventory that approaches 'completeness theater' for the advanced/CRPC section rather than decision-focused groupings.

Basic 28/40|Specialized 42/60|Total 70/100
A1PSA assigned Tier 5 based on explicit clinical embedding evidence
A2Step 1 explicitly narrows the broad scope and states organizational approach before mapping

IL-6 serum biomarker claimed 'ready for clinical use' based on 5 papers with 95% sensitivity/specificity

Hard rules 7, 12, 15, 16 triggered. 5 papers (likely retrospective, small n) = Tier 2 at best, not Tier 4-5. 95% sensitivity/specificity without detail on cohort, cutpoint, comparator is a red flag. User's 'clearly ready' framing not validated. Section E notes known IL-6 heterogeneity in sepsis literature.

Key Strengths

  • Five-tier biomarker maturity system with explicit minimum evidence standards, upgrade/downgrade rules, and 'validation level ≠ maturity tier' distinction is the most rigorous biomarker classification framework in Evidence Insight category
  • 17 hard rules (most in Evidence Insight category) cover virtually all biomarker literature failure modes: citation-based ranking (#16), single-cohort performance conflation (#7), Tier 4/5 casual assignment (#12), and conflict-averaging (#8)
  • Section J (References with citation integrity requirements) is a unique output section that enforces post-output auditability not found in other Evidence Insight skills
  • Conflict-and-inconsistency-rules.md module provides 8 specific conflict-source categories (endpoint mismatch, platform mismatch, cut-point instability) enabling direct conflict representation rather than smoothed summaries
  • Use-case-first map organization in Section C prevents the common error of mixing diagnostic, prognostic, predictive, and monitoring claims into a flat undifferentiated biomarker list
