SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Research workflows often require manually reading dozens of papers and pulling out claims, statistics, and methods with citations. This Skill automates that extraction, producing a structured evidence package with confidence and strength labels so downstream synthesis steps can integrate results without re-reading sources. ## Core Features & Use Cases - Structured Evidence Extraction: Pulls claims, findings, statistics, methods, mechanisms, and limitations from a literature_sources.json package or embedded source list, each with source citations. - Evidence Classification: Labels every item by evidence type (empirical, statistical, theoretical, mechanistic, opinion), confidence (HIGH/MEDIUM/LOW), strength, and domain theme across biomedicine, chemistry, materials, finance, and computer science. - Quality and Traceability Checks: Runs fabrication checks, preserves cross-source contradictions, records metadata gaps, and returns a SUFFICIENT, PARTIAL, or INSUFFICIENT verdict. - Use Case: After a literature retrieval step produces a deduplicated source package, run this Skill to extract traceable evidence items from each paper's abstract or full text, then hand the embedded JSON evidence package to a report-writing step. ## Quick Start Extract evidence from the sources in literature_sources.json for my research objective on transformer architectures and return the evidence package with confidence ratings.

FAQPage Schema
How do I extract evidence from a list of academic papers?▼

Provide a literature_sources.json path or embedded source list plus a research objective. The extractor validates metadata, reads available content, and returns structured evidence items with claims, citations, evidence types, and confidence ratings.

What input format does evidence extraction require?▼

It accepts a literature_sources.json package or embedded list where each source has title, authors, year, venue, source_database, and a DOI or URL. Abstracts or full text improve confidence; metadata-only sources yield LOW-confidence items.

Can evidence extraction work with abstract-only sources?▼

Yes, but abstract-only items are marked LOW or MEDIUM confidence and cite the abstract as the location. Metadata-only sources produce no substantive claims, and all limitations are recorded in Quality Notes.

Does this skill search for new literature or write final reports?▼

No. It only extracts evidence from provided sources. It does not perform literature search, deduplication, cross-source synthesis, or final report writing; those belong to separate retrieval and writing steps.

What happens when some sources cannot be processed?▼

Inaccessible or malformed sources are skipped with limitations recorded, and accumulated evidence is still returned. The verdict becomes PARTIAL or INSUFFICIENT rather than failing the entire extraction task.
