## [0.1.0] - 2025-11-24

### Added

**🎉 Initial Release of @samiyev/guardian**

Code quality guardian for vibe coders and enterprise teams - your AI coding companion that keeps code clean while you move fast.

#### Core Features

- ✨ **Hardcode Detection**
  - Detects magic numbers (timeouts, ports, limits, retries, delays)
  - Detects magic strings (URLs, connection strings, API endpoints, error messages)
  - Smart context analysis to reduce false positives
  - Automatic constant name suggestions based on context
  - Location suggestions for extracted constants (domain/shared/infrastructure)
  - Ignores allowed numbers: -1, 0, 1, 2, 10, 100, 1000
  - Ignores console.log, imports, tests, and exported constants

- 🔄 **Circular Dependency Detection**
  - Detects import cycles in codebase (A → B → A, A → B → C → A, etc.)
  - Shows complete dependency chain for each cycle
  - CLI output with detailed cycle path and severity
  - Supports detection of multiple independent cycles
  - Handles complex graphs with both cyclic and acyclic parts

- 📝 **Naming Convention Enforcement**
  - Layer-based naming rules for Clean Architecture
  - **Domain Layer:**
    - Entities: PascalCase nouns (User.ts, Order.ts)
    - Services: *Service suffix (UserService.ts)
    - Repository interfaces: I*Repository prefix (IUserRepository.ts)
    - Forbidden patterns: Dto, Controller, Request, Response
  - **Application Layer:**
    - Use cases: Verb + Noun in PascalCase (CreateUser.ts, UpdateProfile.ts)
    - DTOs: *Dto, *Request, *Response suffixes
    - Mappers: *Mapper suffix
  - **Infrastructure Layer:**
    - Controllers: *Controller suffix
    - Repository implementations: *Repository suffix
    - Services: *Service or *Adapter suffixes
  - Smart exclusion system for base classes
  - Support for 26 standard use case verbs

- 🏗️ **Architecture Violations**
  - Clean Architecture layer validation
  - Dependency rules enforcement:
    - Domain → can only import Shared
    - Application → can import Domain, Shared
    - Infrastructure → can import Domain, Application, Shared
    - Shared → cannot import anything
  - Layer detection from file paths
  - Import statement analysis

- 🔌 **Framework Leak Detection**
  - Detects framework-specific imports in domain layer
  - Identifies coupling between domain and infrastructure concerns
  - Checks for HTTP framework leaks (Express, Fastify, Koa, Hapi, NestJS)
  - Checks for ORM/Database leaks (Prisma, TypeORM, Sequelize, Mongoose, Drizzle)
  - Checks for external service leaks (AWS SDK, Firebase, Stripe, Twilio)
  - Reports violations with framework type and suggested fixes
  - Helps maintain clean domain boundaries

#### CLI Interface

- 🛠️ **Command-line tool** (`guardian` command)
  - `guardian check <path>` - analyze project
  - `--exclude <dirs>` - exclude directories
  - `--verbose` - detailed output
  - `--no-hardcode` - skip hardcode detection
  - `--no-architecture` - skip architecture checks
  - `--version` - show version
  - `--help` - show help

#### Reporting & Metrics

- 📊 **Comprehensive metrics**
  - Total files analyzed
  - Total functions count
  - Total imports count
  - Layer distribution statistics (domain/application/infrastructure/shared)
  - Detailed violation reports with file:line:column
  - Context snippets for each violation
  - Smart suggestions for fixing issues

#### Developer Experience

- 🤖 **Built for AI-Assisted Development**
  - Perfect companion for Claude, GPT, Copilot, Cursor
  - Catches common AI code smells (hardcoded values, architecture violations)
  - Educational error messages with fix suggestions
  - Designed for vibe coding workflow: AI writes → Guardian reviews → AI fixes → Ship

- 🏢 **Enterprise-Ready**
  - Enforce architectural standards at scale
  - CI/CD integration ready
  - JSON/Markdown output for automation
  - Security: catch hardcoded secrets before production
  - Metrics export for dashboards

#### Examples & Documentation

  - **Good Architecture** (29 files): Complete DDD/Clean Architecture patterns
    - Domain: Aggregates, Entities, Value Objects, Events, Services, Factories, Specifications
    - Application: Use Cases, DTOs, Mappers
    - Infrastructure: Repositories, Controllers
  - **Bad Architecture** (9 files): Anti-patterns to avoid
    - Hardcoded values, Circular dependencies, Framework leaks, Entity exposure, Naming violations
