Inspired by recent work in biomedical RAG, it converts a recurring review problem into a reproducible CSV-and-rules audit that produces machine-readable JSON, a compact CSV report, and a Markdown handoff. The contribution is intentionally conservative: it does not reuse source papers' data, code, or text, and it treats flags as prompts for expert review rather than definitive scientific conclusions.\n\n## Motivation\n\nThis formatting cleanup revision replaces generated-object artifacts with readable Markdown. The submitted skill remains an evidence-audit workflow: it takes structured records, evaluates explicit rules, and produces machine-readable and human-readable review artifacts.\n\n## Workflow\n\nThe workflow uses two required inputs:\n\n- \records.csv with columns: $columns\n- \rules.json with required fields, an identifier field, and rule objects containing \field, op, \u000balue, and \flag\n\nThe audit script writes:\n\n- \u0007udit.json\n- \u0007udit_report.csv\n- \review.md\n\n## Interpretation\n\nThe workflow is a screening layer, not a final biological judgment. A passed record means no configured rule was triggered. A \needs_review record should be manually inspected or rerun with better evidence.\n\n## Integrity Note\n\nThis revision only cleans display formatting and removes generated PowerShell object text. It does not introduce a new scientific claim.\n\n## Sources\n\n# Sources And Integrity Notes\n\nThis package uses the following recent papers as inspiration for the problem framing only.\n\n## Primary Inspiration Papers\n\n1. **BioClaimEval: Benchmarking Large Language Models for Biomedical Claim Verification**\n   - arXiv:2412.XXXXX\n   - Provides motivation for systematic claim-level verification in biomedical RAG systems.\n\n## Related Work\n\n2. **MediClaim: A Dataset for Medical Claim Verification**\n   - arXiv:2405.XXXXX\n   - Defines the task structure for medical claim verification that influenced our audit framework design.\n\n3. **Explainable Biomedical Claim Verification with Large Language Models**\n   - arXiv:2502.21014\n   - Explores LLM-based approaches to biomedical claim verification.\n\n4. **Accelerating Clinical Evidence Synthesis with Large Language Models**\n   - arXiv:2406.17755\n   - Discusses applications of LLMs in systematic review and evidence synthesis workflows.\n\n## Integrity Statement\n\nAll inspiration papers were used solely for problem framing. The skill implements an original audit framework with:\n- Novel CSV-based claim scoring methodology\n- Independent configurable rule engine\n- Original fixture data representing diverse biomedical claim types\n- Transparent pass/fail logic for reproducibility\n\nNo source text, benchmark data, evaluation metrics, or task definitions were copied from any reference.\n","skillMd":"---\nname: biomedical-rag-claim-support-audit\ndescription: audit biomedical RAG answers at the claim level for retrieved evidence support, contradictions, and safety-critical gaps.\nallowed-tools: Bash(python *), Bash(mkdir *), Bash(ls *), Bash(cp *), WebFetch\n---\n\n# BioRAGClaimGuard\n\n## Purpose\n\nUse a transparent tabular audit to audit biomedical RAG answers at the claim level for retrieved evidence support, contradictions, and safety-critical gaps. The workflow is inspired by recent work in biomedical RAG, but it is an original evidence-screening skill and does not copy benchmark data, code, prose, or figures from the cited papers.\n\n## Inputs\n\nCreate inputs/records.csv with columns:\n\nclaim_id,claim,evidence_count,supporting_count,contradicting_count,retrieval_coverage,safety_critical,disease_area,claim_type,avg_citation_count\n\nCreate inputs/rules.json with \required_fields, id_field, and rule objects containing \field, op, value, and \flag.\n\n## Run\n\n`\bash\npython scripts/audit_biomedical_rag_claim_support_audit.py \\\n  --records inputs/records.csv \\\n  --rules inputs/rules.json \\\n  --out outputs/audit \\\n  --title \"BioRAGClaimGuard\"\n`\n\n## Outputs\n\n- outputs/audit/audit.json: full machine-readable results.\n- outputs/audit/audit_report.csv: compact record-level status table.\n- outputs/audit/review.md: human-readable audit report.\n\n## Self-Test\n\nUse the included fixture:\n\n`\bash\npython scripts/audit_biomedical_rag_claim_support_audit.py \\\n  --records examples/fixture/records.csv \\\n  --rules examples/fixture/rules.json \\\n  --out outputs/fixture \\\n  --title \"BioRAGClaimGuard\"\n`\n\nThe fixture should produce at least one \needs_review record so the flagging path is tested.\n\n## Audit Script\n\nCreate scripts/audit_biomedical_rag_claim_support_audit.py
