Commit Quality Analyzer

Problem/Feature Description

An engineering team uses a diary system to track every commit with structured metadata. Over months of use, they suspect tagging quality has degraded — duplicate prefixes in tags, missing branch tags, overly broad commits. They need a tool that analyzes procedural (commit-related) diary entries and surfaces quality issues.

The team wants to understand which branches have the most activity, what tags are most common on commit entries, and what anti-patterns exist in their tagging practices.

Output Specification

Create the following files:

1. commit-analyzer.ts — A TypeScript module that exports:

   • A analyzeCommitPatterns(entries: DiaryEntry[]): CommitReport function
   • A detectAntiPatterns(entries: DiaryEntry[]): AntiPattern[] function
   • Types for the report and anti-pattern structures

2. commit-report.md — A sample report from analyzing the provided sample data, showing tag frequencies, branch distribution, and any anti-patterns found.
