📅 Detailed Roadmap

Version 0.6.0 - Configuration & Presets ⚙️

Target: Q1 2026 (January-February) Priority: 🔥 CRITICAL

Why Critical: All competitors (SonarQube, ESLint, dependency-cruiser) have configuration. Without this, Guardian cannot be customized for different teams/projects.

Features

1. Configuration File Support

// guardian.config.js (primary)
export default {
    // Zero-config presets
    preset: 'clean-architecture',  // or 'ddd', 'hexagonal', 'onion'

    // Rule configuration
    rules: {
        'hardcode/magic-numbers': 'error',
        'hardcode/magic-strings': 'warn',
        'architecture/layer-violation': 'error',
        'architecture/framework-leak': 'error',
        'architecture/entity-exposure': 'error',
        'circular-dependency': 'error',
        'naming-convention': 'warn',
        'dependency-direction': 'error',
        'repository-pattern': 'error',
    },

    // Custom layer paths
    layers: {
        domain: 'src/core/domain',
        application: 'src/core/application',
        infrastructure: 'src/adapters',
        shared: 'src/shared',
    },

    // Exclusions
    exclude: [
        '**/*.test.ts',
        '**/*.spec.ts',
        'scripts/',
        'migrations/',
        'node_modules/',
    ],

    // Per-rule ignores
    ignore: {
        'hardcode/magic-numbers': {
            'src/config/constants.ts': [3000, 8080],
        },
    },
}

2. Built-in Presets

// Preset: clean-architecture (default)
preset: 'clean-architecture'
// Enables: layer-violation, dependency-direction, naming-convention

// Preset: ddd
preset: 'ddd'
// Enables all DDD patterns: aggregates, value-objects, domain-events

// Preset: hexagonal (Ports & Adapters)
preset: 'hexagonal'
// Validates port/adapter separation

// Preset: minimal (for prototyping)
preset: 'minimal'
// Only critical rules: hardcode, circular-deps

3. Framework-Specific Presets

// NestJS
preset: 'nestjs-clean-architecture'

// Express
preset: 'express-clean-architecture'

// Next.js
preset: 'nextjs-clean-architecture'

4. Configuration Discovery

Support multiple config file formats:

• guardian.config.js (ES modules)
• guardian.config.cjs (CommonJS)
• .guardianrc (JSON)
• .guardianrc.json
• package.json (guardian field)

5. CLI Override

# Override config from CLI
guardian check ./src --rule hardcode/magic-numbers=off

# Use specific config file
guardian check ./src --config custom-config.js

# Generate config
guardian init --preset clean-architecture

Implementation Tasks

• Create config parser and validator
• Implement preset system
• Add config discovery logic
• Update AnalyzeProject use case to accept config
• CLI integration for config override
• Add guardian init command
• Documentation and examples
• Tests (config parsing, presets, overrides)

    I --> S

    style D fill:#4CAF50
    style A fill:#2196F3

Version 0.9.0 - Auto-Fix & Code Generation 🤖

Target: Q2 2026 (May) Priority: 🚀 GAME-CHANGER (UNIQUE!)

Why Game-Changer: No competitor has intelligent auto-fix for architecture. This makes Guardian unique!

Features

1. Auto-Fix Hardcode

# Fix all hardcode violations automatically
guardian fix ./src --auto

# Preview changes
guardian fix ./src --dry-run

# Fix specific types
guardian fix ./src --type hardcode
guardian fix ./src --type naming

Example:

// Before
const timeout = 5000
app.listen(3000)

// After (auto-generated constants.ts)
export const DEFAULT_TIMEOUT_MS = 5000
export const DEFAULT_PORT = 3000

// After (fixed code)
import { DEFAULT_TIMEOUT_MS, DEFAULT_PORT } from './constants'
const timeout = DEFAULT_TIMEOUT_MS
app.listen(DEFAULT_PORT)

2. Generate Constants File

# Extract all hardcodes to constants
guardian generate constants ./src --output src/config/constants.ts

# Generated file:
// src/config/constants.ts
export const DEFAULT_TIMEOUT_MS = 5000
export const DEFAULT_PORT = 3000
export const MAX_RETRIES = 3
export const API_BASE_URL = 'http://localhost:8080'

3. Fix Naming Violations

# Rename files to match conventions
guardian fix naming ./src --auto

# Before: src/application/use-cases/user.ts
# After:  src/application/use-cases/CreateUser.ts

4. AI-Friendly Fix Prompts

# Generate prompt for AI assistant
guardian check ./src --format ai-prompt > fix-prompt.txt

# Output (optimized for Claude/GPT):
"""
Fix the following Guardian violations:

1. HARDCODE (src/api/server.ts:15)
   - Replace: app.listen(3000)
   - With: Extract 3000 to DEFAULT_PORT constant
   - Location: Create src/config/constants.ts

2. FRAMEWORK_LEAK (src/domain/User.ts:5)
   - Remove: import { Request } from 'express'
   - Reason: Domain layer cannot import frameworks
   - Suggestion: Use dependency injection via interfaces

[Complete fix suggestions...]
"""

# Then feed to Claude:
# cat fix-prompt.txt | pbcopy
# Paste into Claude: "Fix these Guardian violations"

5. Interactive Fix Mode

# Interactive fix selection
guardian fix ./src --interactive

# Prompts:
# ? Fix hardcode in server.ts:15 (3000)? (Y/n)
# ? Suggested constant name: DEFAULT_PORT
#   [Edit name] [Skip] [Fix All]

6. Refactoring Commands

# Break circular dependency
guardian refactor circular ./src/services/UserService.ts
# Suggests: Extract shared interface

# Fix layer violation
guardian refactor layer ./src/domain/entities/User.ts
# Suggests: Move framework imports to infrastructure

Implementation Tasks

• Implement auto-fix engine (AST transformation)
• Constants extractor and generator
• File renaming system
• AI prompt generator
• Interactive fix mode
• Refactoring suggestions
• Safe rollback mechanism
• Documentation and examples
• Tests (fix scenarios, edge cases)
