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.

Activation Triggers

Triggered when users ask about Git analysis, code hotspots, who owns what code, secret scanning, security audits of commit history, or optimizing code review assignments.
