Kiss Git Validate

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 must match one of these patterns:

1. Sequential: ^[0-9]{3,}- (e.g., 001-feature-name, 042-fix-bug, 1000-big-feature)
2. Timestamp: ^[0-9]{8}-[0-9]{6}- (e.g., 20260319-143022-feature-name)

Execution

If on a feature branch (matches either pattern):

• Output: ✓ On feature branch: <branch-name>
• Check if the corresponding spec directory exists under specs/:
  • For sequential branches, look for specs/<prefix>-* where prefix matches the numeric portion
  • For timestamp branches, look for specs/<prefix>-* where prefix matches the YYYYMMDD-HHMMSS portion
• If spec directory exists: ✓ Spec directory found: <path>
• If spec directory missing: ⚠ No spec directory found for prefix <prefix>

If NOT on a feature branch:

• Output: ✗ Not on a feature branch. Current branch: <branch-name>
• Output: Feature branches should be named like: 001-feature-name or 20260319-143022-feature-name

Graceful Degradation

If Git is not installed or the directory is not a Git repository:

• Check the KISS_FEATURE environment variable as a fallback
• If set, validate that value against the naming patterns
• If not set, skip validation with a warning
