Module git 

Git branch tracking utilities for mi6.

This module provides functionality to:

• Capture the current git branch from a working directory
• Detect git branch-changing commands in shell commands

Branch Info Capture

The parse_branch_info function captures the git branch name.

Note: This function does not extract issue/PR numbers from branch names. Branch naming conventions are too inconsistent and led to false positives (e.g., upgrade-text-fix-2 being incorrectly parsed as issue #2). Issue and PR numbers are now only extracted from explicit gh CLI commands (see the github module).

Branch-Changing Command Detection

The is_branch_changing_command function detects git commands that change the current branch, triggering re-capture of branch info.

Detected Commands

Command	Description
git checkout <branch>	Switch branches
git checkout -b <branch>	Create and switch
git switch <branch>	Modern branch switch
git worktree add <path>	Create worktree
git merge <branch>	Merge (may fast-forward)
git rebase <branch>	Rebase onto branch
git pull	Pull (may merge/rebase)

Chained Command Support

Commands are split on &, |, and ; to detect branch changes in compound commands:

echo foo && git checkout main   -> detected
git status; git checkout main   -> detected
cargo build && git switch dev   -> detected

Limitations

1. Chained commands - Simple split on delimiters; doesn’t handle quoted delimiters
