Validate Feature Branch

Validate that the current Git branch follows the expected feature branch naming conventions.

Prerequisites

• Check if Git is available by running git rev-parse --is-inside-work-tree 2>/dev/null
• If Git is not available, output a warning and skip validation:

  [specify] Warning: Git repository not detected; skipped branch validation

Validation Rules

Get the current branch name:

git rev-parse --abbrev-ref HEAD

The branch name's final path segment must start with one of these feature markers:

1. Sequential: [0-9]\{3,\}- (e.g., 001-feature-name, 042-fix-bug, 1000-big-feature, jdoe/web/008-guided-tour)
2. Timestamp: [0-9]\{8\}-[0-9]\{6\}- (e.g., 20260319-143022-feature-name, jdoe/web/20260319-143022-feature-name)

Execution
