Summary

Add early exit to commit-msg-check.sh for non-git commands to avoid spawning Python.

Implementation: Change V5.5.0 (Sprint 8)

Problem

The hook currently:

Reads stdin
Spawns Python to parse JSON (50-100ms overhead)
Checks if git commit -m command
Exits if not

Python startup is expensive. This happens on EVERY Bash command.

Solution

Add early check BEFORE Python:

INPUT=$(cat)

# Quick check - exit immediately if not a git commit command
if ! echo "$INPUT" | grep -q '"command".*git.*commit'; then
    exit 0
fi

Acceptance Criteria

Hook exits immediately for non-git-commit commands
Commit message validation still works for git commit -m
No regression in existing functionality
Python only spawned when actually needed

Files to Modify

plugins/git-flow/hooks/commit-msg-check.sh (add early check after line 7)

Milestone: Sprint 8 - Hook Efficiency Quick Wins
