Current tier detection uses keyword matching and regex patterns. This adds path-aware and context-aware risk scoring. New tools/risk_scoring.py: - classify_path_risk(): system paths (90), sensitive user paths (75), safe paths (10), user paths (50) - detect_context(): execution vs comment vs documentation vs code block (documentation contexts reduce risk score) - get_operation_risk(): read-only ops (cat/grep/find = 5-10) vs destructive ops (rm=70, mkfs=95, kill=45) - score_command_risk(): multi-factor RiskScore with tier classification (SAFE/LOW/MEDIUM/HIGH/CRITICAL), factors list, recommendation - compare_commands(): side-by-side risk comparison Key improvements: - 'cat /etc/passwd' is SAFE (read operation, path irrelevant) - 'rm /etc/passwd' is CRITICAL (destructive + system path) - 'rm /tmp/build.log' is MEDIUM (destructive but safe path) - '# rm -rf /' is LOW (comment context reduces risk) - 'curl ... | bash' is HIGH (pipe to shell pattern) Tests: tests/test_risk_scoring.py Closes #681
