majiayu000 Citation Extraction Skill
Overview
Validates citations by calculating Jaccard overlap (intersection over union) between cited text and source passages. Enforces ≥0.7 threshold for quality.
When to Use
- Validate citations in clinical summaries
- Calculate Jaccard overlap for Evaluator metrics
- Extract source text spans for claims
Installation
IMPORTANT: This skill has its own isolated virtual environment (.venv) managed by uv. Do NOT use system Python.
Initialize the skill's environment:
# From the skill directory
cd .agent/skills/citation-extraction
uv sync # Creates .venv (no external dependencies, uses Python stdlib)
Usage
CRITICAL: Always use uv run to execute code with this skill's .venv, NOT system Python.
# From .agent/skills/citation-extraction/ directory
# Run with: uv run python -c "..."
from citation_extraction import CitationExtractor
extractor = CitationExtractor()
# Validate citation
jaccard = extractor.calculate_jaccard_overlap(
claim_text="Patient has hypertension",
source_text="Patient diagnosed with hypertension 10 years ago"
)
if jaccard >= 0.7:
print(f"Valid citation (Jaccard: {jaccard})")
