# Shared path-based read tool handling for Claude Code and Cursor hooks.

# Usage (after defining safe_jq in the hook):

# On success: sets GUARDRAIL_TOOL=read and CONTEXT_JSON with file_path; returns 0.
# On skip (no path / not a path-based read tool): returns 1 — caller may allow without evaluator.
