/watzup

Quick review command that analyzes your current branch, recent commits, and code changes to provide a comprehensive summary of all work done. Perfect for stand-ups, code reviews, or understanding recent activity.

Syntax

/watzup

What It Does

The /watzup command provides a comprehensive overview of:

  1. Current Branch Status

    • Active branch name
    • Comparison with main/master branch
    • Ahead/behind commit count

  2. Recent Commits

    • Commit messages
    • Author information
    • Timestamps
    • Files affected

  3. Code Changes Analysis

    • Files modified, added, or removed
    • Lines added/deleted
    • Change patterns and themes

  4. Overall Impact Assessment

    • Features added
    • Bugs fixed
    • Refactoring done
    • Breaking changes (if any)

  5. Quality Evaluation

    • Code organization
    • Test coverage impact
    • Documentation updates

Limitations

What /watzup Does NOT Do

❌ Does not start implementation ❌ Does not modify code ❌ Does not create commits ❌ Does not deploy code ❌ Does not run tests

✅ Only analyzes and reports

When NOT to Use

Before Starting Work:

❌ /watzup
✅ /plan [feature]

When Implementing:

❌ /watzup
✅ /cook [feature]

When Fixing Bugs:

❌ /watzup
✅ /fix [issue]
  • /journal - Detailed work documentation
