Repo Audit — Deep Analysis of Git History

Perform three-dimensional analysis on a Git repository: hotspot file detection, code ownership analysis, and secret leak scanning.

Feature Overview

1. Hotspot File Analysis (scripts/hotfiles.sh)

Identify the most frequently changed files in a repository to help spot:

• High-risk code areas (frequent changes = potential instability)
• Files that deserve extra attention during code review
• Modules that may need splitting or refactoring

Usage:

bash scripts/hotfiles.sh [options]

Option	Description	Default
--repo PATH	Repository path	Current directory
--top N	Show top N files	20
--since DATE	Start date (e.g. 2024-01-01)	None
--until DATE	End date	None
--author AUTHOR	Filter by author	None
--format FORMAT	Output format: table / csv / json	table

2. Code Ownership Analysis (scripts/ownership.sh)

Analyze actual code ownership, reporting for each contributor within the specified scope:

• Commit count and percentage
• Lines changed (additions/deletions)
• Last active date

Usage:

bash scripts/ownership.sh [options]

Option	Description	Default
--repo PATH	Repository path	Current directory
--path SUBPATH	Analyze a specific subdirectory or file	Entire repo
--top N	Show top N contributors	10
--since DATE	Start date	None
--format FORMAT	Output format: table / csv / json	table

3. Secret Leak Scanning (scripts/secret-scan.sh)

Scan the full Git history (including deleted commits) for common secrets and sensitive information:

• AWS Access Key / Secret Key
• GitHub / GitLab / Slack Tokens
• SSH Private Keys
• Generic API Keys, passwords, and secret patterns

Usage:

bash scripts/secret-scan.sh [options]

Option	Description	Default
--repo PATH	Repository path	Current directory
--branch BRANCH	Scan a specific branch	All branches
--since DATE	Start date	None
--format FORMAT	Output format: table / csv / json	table
--severity LEVEL	Minimum severity level: low / medium / high	low

Use Cases

• Security audits: Scan history for leaked secrets before deploying to production
• Code review optimization: Identify hotspot files and prioritize reviewing high-risk areas
• Team collaboration: Understand who knows which parts of the code best, and assign reviews accordingly
• Tech debt assessment: Frequently changed files are strong candidates for refactoring

Dependencies

• git (>= 2.20)
• bash (>= 4.0)
• Standard Unix utilities: awk, sort, head, grep

No additional dependencies or paid APIs required.
