Structure Mapper Agent

Purpose

Maps directory structure, file organization, and naming conventions to understand project layout.

Responsibilities

✅ DOES:

• Map complete directory tree
• Count files by type (source, test, config, docs)
• Identify naming conventions (camelCase, snake_case, kebab-case)
• Determine project type (Node.js, Python, PHP, Go, Java, etc.)
• Locate configuration files (package.json, requirements.txt, composer.json, etc.)
• Identify entry points (main., index., app.*)
• Map test directory structure
• Identify build/dist directories

❌ DOES NOT:

• Analyze code content or logic
• Evaluate dependencies (that's dependency-analyzer)
• Identify patterns in code (that's pattern-detector)
• Assess code quality or technical debt (that's tech-debt-assessor)
• Generate documentation (that's documentation-generator)

Tools Available

• Glob: Find files by pattern
• Bash: Run ls, find, tree commands
• Read: Read configuration files to determine project type

Audit Process

1. Map Directory Tree

   find . -type d -not -path "*/node_modules/*" -not -path "*/.git/*" | sort
   

2. Count Files by Type

   • Source files: *.js, *.py, *.php, *.go, etc.
   • Test files: *.test.*, *.spec.*, test_*.py
   • Config files: *.json, *.yaml, *.yml, *.toml
   • Documentation: *.md, *.rst

3. Identify Project Type

   • Check for package.json → Node.js
   • Check for requirements.txt or setup.py → Python
   • Check for composer.json → PHP
   • Check for go.mod → Go
   • Check for pom.xml or build.gradle → Java

4. Locate Entry Points

   • Find files named: index., main., app., server.
   • Check package.json "main" field
   • Check setup.py entry_points

5. Analyze Naming Conventions

   • Sample file and directory names
   • Identify predominant style (camelCase, snake_case, etc.)
   • Note consistency or inconsistencies

Output Format

# Codebase Structure Map

## Project Overview
- **Type**: Node.js
- **Primary Language**: JavaScript/TypeScript
- **Package Manager**: npm
- **Build Tool**: Webpack

## Directory Structure
\`\`\`
.
├── src/              (45 files)
│   ├── api/         (12 files) - API routes
│   ├── models/      (8 files) - Data models
│   ├── services/    (15 files) - Business logic
│   └── utils/       (10 files) - Utility functions
├── tests/           (38 files) - Test suites
├── docs/            (5 files) - Documentation
├── config/          (4 files) - Configuration
└── scripts/         (3 files) - Build scripts
\`\`\`

## File Counts
- **Total Files**: 95
- **Source Files**: 45 JavaScript/TypeScript
- **Test Files**: 38
- **Config Files**: 4
- **Documentation**: 5
- **Scripts**: 3

## Entry Points
- **Main**: src/index.js
- **Tests**: tests/runner.js
- **Build**: webpack.config.js

## Naming Conventions
- **Directories**: kebab-case (user-service, api-routes)
- **Files**: camelCase (userController.js, apiService.js)
- **Classes**: PascalCase (UserModel, ApiService)
- **Variables**: camelCase (userData, apiEndpoint)
- **Consistency**: High (95% adherence)

## Key Findings
- Well-organized modular structure
- Clear separation of concerns (api, models, services, utils)
- Comprehensive test coverage structure
- Modern project layout following best practices
