+  - New `IAnemicModelDetector` domain interface
+  - Integrated into CLI with detailed violation reports
+  - 12 comprehensive tests for anemic model detection
+
+- 📦 **New shared constants** - Centralized constants for better code maintainability:
+  - `CLASS_KEYWORDS` - TypeScript class and method keywords (constructor, public, private, protected)
+  - `EXAMPLE_CODE_CONSTANTS` - Documentation example code strings (ORDER_STATUS_PENDING, ORDER_STATUS_APPROVED, CANNOT_APPROVE_ERROR)
+  - `ANEMIC_MODEL_MESSAGES` - 8 suggestion messages for fixing anemic models
+
+- 📚 **Example files** - Added DDD examples demonstrating anemic vs rich domain models:
+  - `examples/bad/domain/entities/anemic-model-only-getters-setters.ts`
+  - `examples/bad/domain/entities/anemic-model-public-setters.ts`

+## 11. Anemic Domain Model Detection
+
+### Martin Fowler's Original Blog Post (2003)
+
+**Blog Post: "Anemic Domain Model"** (November 25, 2003)
+- Author: Martin Fowler
+- Published: November 25, 2003
+- Described as an anti-pattern related to domain driven design and application architecture
+- Basic symptom: domain objects have hardly any behavior, making them little more than bags of getters and setters
+- Reference: [Martin Fowler - Anemic Domain Model](https://martinfowler.com/bliki/AnemicDomainModel.html)
+
+**Key Problems Identified:**
+- "The basic symptom of an Anemic Domain Model is that at first blush it looks like the real thing"
+- "There are objects, many named after the nouns in the domain space, and these objects are connected with the rich relationships and structure that true domain models have"
+- "The catch comes when you look at the behavior, and you realize that there is hardly any behavior on these objects"
+- "This is contrary to the basic idea of object-oriented design; which is to combine data and process together"
+
+**Why It's an Anti-pattern:**
+- Fowler argues that anemic domain models incur all of the costs of a domain model, without yielding any of the benefits
+- The logic that should be in a domain object is domain logic - validations, calculations, business rules
+- Separating data from behavior violates core OOP principles
+- Reference: [Wikipedia - Anemic Domain Model](https://en.wikipedia.org/wiki/Anemic_domain_model)
+
+### Rich Domain Model vs Transaction Script
+
+**Martin Fowler: Transaction Script Pattern**
+- Transaction Script organizes business logic by procedures where each procedure handles a single request
+- Good for simple logic with not-null checks and basic calculations
+- Reference: [Martin Fowler - Transaction Script](https://martinfowler.com/eaaCatalog/transactionScript.html)
+
+**When to Use Rich Domain Model:**
+- If you have complicated and everchanging business rules involving validation, calculations, and derivations
+- Object model handles complex domain logic better than procedural scripts
+- Reference: [InformIT - Domain Logic Patterns](https://www.informit.com/articles/article.aspx?p=1398617&seqNum=2)
+
+**Comparison:**
+- Transaction Script is better for simple logic
+- Domain Model is better when things get complicated with complex business rules
+- You can refactor from Transaction Script to Domain Model, but it's a harder change
+- Reference: [Medium - Transaction Script vs Domain Model](https://medium.com/@vibstudio_7040/transaction-script-active-record-and-domain-model-the-good-the-bad-and-the-ugly-c5b80a733305)
+
+### Domain-Driven Design Context
+
+**Eric Evans: Domain-Driven Design** (2003)
+- Entities should have both identity and behavior
+- Rich domain models place business logic within domain entities
+- Anemic models violate DDD principles by separating data from behavior
+- Reference: Already covered in Section 10 - [Domain-Driven Design Book](#domain-driven-design)
+
+**Community Discussion:**
+- Some argue anemic models can follow SOLID design principles
+- However, consensus among DDD practitioners aligns with Fowler's anti-pattern view
+- Reference: [Stack Overflow - Anemic Domain Model Anti-Pattern](https://stackoverflow.com/questions/6293981/concrete-examples-on-why-the-anemic-domain-model-is-considered-an-anti-pattern)

+
+## 12. Aggregate Boundary Validation (DDD Tactical Patterns)
+
+### Eric Evans: Domain-Driven Design (2003)
+
+**Original Book Definition:**
+- Aggregate: "A cluster of associated objects that we treat as a unit for the purpose of data changes"
+- An aggregate defines a consistency boundary around one or more entities
+- Exactly one entity in an aggregate is the root
+- Reference: [Microsoft Learn - Tactical DDD](https://learn.microsoft.com/en-us/azure/architecture/microservices/model/tactical-ddd)
+
+**DDD Reference Document** (2015)
+- Official Domain-Driven Design Reference by Eric Evans
+- Contains comprehensive definitions of Aggregates and boundaries
+- Reference: [Domain Language - DDD Reference PDF](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)

+- Practical examples of aggregate boundary enforcement
+- Reference: [SOCADK - Tactical DDD](https://socadk.github.io/design-practice-repository/activities/DPR-TacticDDD.html)
+
+### Why Aggregate Boundaries Matter
+
+**Transactional Boundary:**
+- What makes it an aggregate is the transactional boundary
+- Changes to aggregate must be atomic
+- Ensures consistency within the boundary
+- Reference: [Medium - Mastering Aggregate Design](https://medium.com/ssense-tech/ddd-beyond-the-basics-mastering-aggregate-design-26591e218c8c)
+
+**Cross-Aggregate References:**
+- Aggregates should only reference other aggregates by ID, not direct entity references
+- Prevents tight coupling between aggregates
+- Maintains clear boundaries

+## Anemic Domain Model Detection
+
+### Why it matters
+
+Anemic domain models violate core OOP principles:
+- ❌ **No behavior** - Entities become data bags with only getters/setters
+- ❌ **Logic in services** - Business logic scattered across service layers
+- ❌ **Violates OOP** - Separates data from behavior
+- ❌ **Higher complexity** - Loses benefits of domain modeling
+
+### Who says so?
+
+**Martin Fowler's Original Anti-Pattern:**
+- **Blog Post: "Anemic Domain Model"** (November 25, 2003)
+  > "The basic symptom of an Anemic Domain Model is that at first blush it looks like the real thing. There are objects, many named after the nouns in the domain space... The catch comes when you look at the behavior, and you realize that there is hardly any behavior on these objects."

+## Aggregate Boundary Validation
+
+### Why it matters
+
+Proper aggregate boundaries ensure:
+- ✅ **Consistency** - Atomic changes within boundaries
+- ✅ **Low coupling** - Aggregates are loosely connected
+- ✅ **Clear transactions** - One aggregate = one transaction
+- ✅ **Maintainability** - Boundaries prevent complexity spread
+
+### The Rules
+
+**Vaughn Vernon's Four Rules (2013):**
+1. **Model True Invariants in Consistency Boundaries**
+2. **Design Small Aggregates**
+3. **Reference Other Aggregates by Identity**
+4. **Use Eventual Consistency Outside the Boundary**
+
+### Who says so?
+
+**Eric Evans: Domain-Driven Design (2003)**
+- **Original Definition**:
+  > "A cluster of associated objects that we treat as a unit for the purpose of data changes"
+- An aggregate defines a consistency boundary

+## Secret Detection
+
+### Why it matters
+
+Hardcoded secrets create critical security risks:
+- 🔴 **Data breaches** - Exposed credentials lead to unauthorized access
+- 🔴 **Production incidents** - Leaked tokens cause service disruptions
+- 🔴 **Compliance violations** - GDPR, PCI-DSS, SOC 2 requirements
+- 🔴 **Impossible to rotate** - Secrets in code are difficult to change
