PR Analyzer

Analyzes git diff between branches to assess review complexity and identify risks.

# Analyze current branch against main
python scripts/pr_analyzer.py /path/to/repo

# Compare specific branches
python scripts/pr_analyzer.py . --base main --head feature-branch

# JSON output for integration
python scripts/pr_analyzer.py /path/to/repo --json

What it detects:

Hardcoded secrets (passwords, API keys, tokens)
SQL injection patterns (string concatenation in queries)
Debug statements (debugger, console.log)
ESLint rule disabling
TypeScript any types
TODO/FIXME comments

Output includes:

Complexity score (1-10)
Risk categorization (critical, high, medium, low)
File prioritization for review order
Commit message validation

Code Quality Checker

Analyzes source code for structural issues, code smells, and SOLID violations.

# Analyze a directory
python scripts/code_quality_checker.py /path/to/code

# Analyze specific language
python scripts/code_quality_checker.py . --language python

# JSON output
python scripts/code_quality_checker.py /path/to/code --json

What it detects:

Long functions (>50 lines)
Large files (>500 lines)
God classes (>20 methods)
Deep nesting (>4 levels)
Too many parameters (>5)
High cyclomatic complexity
Missing error handling
Unused imports
Magic numbers

Thresholds:

Issue	Threshold
Long function	>50 lines
Large file	>500 lines
God class	>20 methods
Too many params	>5
Deep nesting	>4 levels
High complexity	>10 branches

Review Report Generator

Combines PR analysis and code quality findings into structured review reports.

# Generate report for current repo
python scripts/review_report_generator.py /path/to/repo

# Markdown output
python scripts/review_report_generator.py . --format markdown --output review.md

# Use pre-computed analyses
python scripts/review_report_generator.py . \
  --pr-analysis pr_results.json \
  --quality-analysis quality_results.json

Report includes:

Review verdict (approve, request changes, block)
Score (0-100)
Prioritized action items
Issue summary by severity
Suggested review order

Verdicts:

Score	Verdict
90+ with no high issues	Approve
75+ with ≤2 high issues	Approve with suggestions
50-74	Request changes
<50 or critical issues	Block

Reference Guides

Code Review Checklist

references/code_review_checklist.md

Systematic checklists covering:

Pre-review checks (build, tests, PR hygiene)
Correctness (logic, data handling, error handling)
Security (input validation, injection prevention)
Performance (efficiency, caching, scalability)
Maintainability (code quality, naming, structure)
Testing (coverage, quality, mocking)
Language-specific checks

Coding Standards

references/coding_standards.md

Language-specific standards for:

TypeScript (type annotations, null safety, async/await)
JavaScript (declarations, patterns, modules)
Python (type hints, exceptions, class design)
Go (error handling, structs, concurrency)
Swift (optionals, protocols, errors)
Kotlin (null safety, data classes, coroutines)

Common Antipatterns

references/common_antipatterns.md

Antipattern catalog with examples and fixes:

Structural (god class, long method, deep nesting)
Logic (boolean blindness, stringly typed code)
Security (SQL injection, hardcoded credentials)
Performance (N+1 queries, unbounded collections)
Testing (duplication, testing implementation)
Async (floating promises, callback hell)

Languages Supported

Language	Extensions
Python	`.py`
TypeScript	`.ts`, `.tsx`
JavaScript	`.js`, `.jsx`, `.mjs`
