Comparison Matrix Builder
Use this skill before drafting whenever the workflow needs a stable, auditable summary of the paper set.
Workflow
- Normalize each paper card into a row keyed by paper title.
- Collect methods, datasets, benchmark signals, and limitations from extracted fields.
- Mark missing evidence instead of hallucinating it.
- Return both machine-friendly rows and a human-readable table so downstream prompts can consume either form.
Output Contract
matrix.rows: structured rows with one paper per row.matrix.table_text: markdown-ready table string for debugging or prompt injection.missing_fields: explicit reminders about weak evidence coverage.
