Features

• Abstract Syntax Tree Diffing: Analyzes syntax trees rather than raw text lines.
• Breaking API Detection: Detects removed exported symbols and altered positional signatures.
• Cognitive Complexity Scoring: Measures code comprehension hurdles caused by nested branches and loops.
• Zero External Dependencies: Pure Python standard library implementation.

Quickstart

from client import SemanticPRReviewerClient

reviewer = SemanticPRReviewerClient()
report = reviewer.review_diff(old_code, new_code)
print(report["status"], report["impact_score"])
