Automated Code Review Agent

Agent Purpose

This agent automatically performs comprehensive code reviews across the entire project codebase, generating review documents and task lists according to the guidelines in .cursor/rules/review.md.

Agent Configuration

Detection & Scope

• Project Type Detection: Automatically identify project type from file structure and configuration files
• File Type Mapping: Map project types to relevant source file extensions
• Scope: Full project crawl (not just changed files)
• Frequency: On-demand execution (not continuous monitoring)

Project Type Detection Logic

NextJS Projects

• Indicators: next.config.js/ts, package.json with Next.js dependency, app/ or src/app/ directory
• File Extensions: .tsx, .ts, .jsx, .js, .css, .scss, .mdx
• Key Directories: src/, app/, components/, lib/, types/

Python Projects

• Indicators: requirements.txt, pyproject.toml, setup.py, __init__.py files
• File Extensions: .py, .pyx, .pyi
• Key Directories: src/, app/, tests/, migrations/

C++ Projects

• Indicators: CMakeLists.txt, Makefile, *.vcxproj, *.sln
• File Extensions: .cpp, .cc, .cxx, .h, .hpp, .hxx
• Key Directories: src/, include/, lib/, tests/

Rust Projects

• Indicators: Cargo.toml, Cargo.lock
• File Extensions: .rs
• Key Directories: src/, tests/, examples/

Generic/Unknown Projects

• Fallback: Review all common source files
• File Extensions: .js, .ts, .jsx, .tsx, .py, .cpp, .h, .rs, .go, .java

Review Process

Step 1: Project Analysis

1. Detect Project Type: Analyze project structure and configuration files
2. Identify Source Files: Map relevant file extensions and directories
3. Generate File List: Create comprehensive list of files to review
4. Load Review Guidelines: Read and parse .cursor/rules/review.md

Step 2: File-by-File Review

For each source file:

1. Read File Content: Load and parse file content
2. Apply Review Questionnaire: Systematically evaluate against all 12 review criteria
3. Generate Findings: Document issues, improvements, and observations
4. Categorize Issues: Group by Critical Issues, Code Quality, Best Practices, etc.

Step 3: Document Generation

1. Create Review Documents: Generate review.{filename}.MMDD.md files
2. Create Task Lists: Generate tasks.code-review.{filename}.MMDD.md files
3. Organize by Priority: P0 (Critical) → P1 (Quality) → P2 (Best Practices) → P3 (Enhancements)
4. Add YAML Headers: Include proper metadata for all generated files

Step 4: Summary Report

1. Generate Overview: Create summary of all findings across the project
2. Prioritize Actions: Identify highest-impact improvements
3. Create Index: Generate master index of all review documents

Review Criteria Application

Platform-Specific Reviews

• NextJS: Focus on Sections 8, 11, 12 (Performance, Accessibility, React/TypeScript/NextJS)
• Python: Focus on Sections 1-7, 9-10 (Bugs, Code Quality, Security, Testing)
• C++: Focus on Sections 1-7, 9-10 (Bugs, Code Quality, Security, Testing)
• Rust: Focus on Sections 1-7, 9-10 (Bugs, Code Quality, Security, Testing)

File Type Specifics

• Component Files: Emphasize Sections 5, 11, 12 (Component Structure, Accessibility, React patterns)
• Utility Files: Emphasize Sections 4, 6, 7 (Code Duplication, Patterns, Documentation)
• Configuration Files: Emphasize Sections 2, 6 (Hard-coded Elements, Best Practices)
• Test Files: Emphasize Sections 10, 7 (Testing Coverage, Documentation)

Automation Triggers

Manual Execution

• Command: npm run code-review or pnpm code-review
