# Agent Forum v4 - Pre-Commit Hook
#
# This hook executes Git-Native Agent Collaboration Ecosystem tasks before every commit:
# 1. Generates Semantic Code Intelligence Protocol (SCIP) & AST graphs.
# 2. Runs fast Static Analysis (Semgrep) if available.
# 3. Validates Bounded Model Checking rules via transitions.json.
# 4. Writes telemetry/reasoning payloads to Git Notes.
