+## 15. Domain Event Usage Validation
+
+### Eric Evans: Domain-Driven Design (2003)
+
+**Original Definition:**
+- Domain Events: "Something happened that domain experts care about"
+- Events capture facts about the domain that have already occurred
+- Distinct from system events - they model business-relevant occurrences
+- Reference: [Martin Fowler - Domain Event](https://martinfowler.com/eaaDev/DomainEvent.html)
+
+**Book: Domain-Driven Design** (2003)
+- Author: Eric Evans
+- Publisher: Addison-Wesley Professional
+- ISBN: 978-0321125217
+- Domain Events weren't explicitly in the original book but evolved from DDD community
+- Reference: [DDD Community - Domain Events](https://www.domainlanguage.com/)
+
+### Vaughn Vernon: Implementing Domain-Driven Design (2013)
+
+**Chapter 8: Domain Events**
+- Author: Vaughn Vernon
+- Comprehensive coverage of Domain Events implementation
+- "Model information about activity in the domain as a series of discrete events"
+- Reference: [Amazon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
+
+**Key Principles:**
+- Events should be immutable
+- Named in past tense (OrderPlaced, UserRegistered)
+- Contain all data needed by handlers
+- Enable loose coupling between aggregates
+
+### Martin Fowler's Event Patterns
+
+**Event Sourcing:**
+- "Capture all changes to an application state as a sequence of events"
+- Events become the primary source of truth
+- Reference: [Martin Fowler - Event Sourcing](https://martinfowler.com/eaaDev/EventSourcing.html)
+
+**Event-Driven Architecture:**
+- Promotes loose coupling between components
+- Enables asynchronous processing
+- Reference: [Martin Fowler - Event-Driven](https://martinfowler.com/articles/201701-event-driven.html)
+
+### Why Direct Infrastructure Calls Are Bad
+
+**Coupling Issues:**
+- Direct calls create tight coupling between domain and infrastructure
+- Makes testing difficult (need to mock infrastructure)
+- Violates Single Responsibility Principle
+- Reference: [Microsoft - Domain Events Design](https://learn.microsoft.com/en-us/dotnet/architecture/microservices/microservice-ddd-cqrs-patterns/domain-events-design-implementation)
+
+**Benefits of Domain Events:**
+- Decouples domain from side effects
+- Enables eventual consistency
+- Improves testability
+- Supports audit logging naturally
+- Reference: [Jimmy Bogard - Domain Events](https://lostechies.com/jimmybogard/2010/04/08/strengthening-your-domain-domain-events/)
+
+---
+
+## 16. Value Object Immutability
+
+### Eric Evans: Domain-Driven Design (2003)
+
+**Value Object Definition:**
+- "An object that describes some characteristic or attribute but carries no concept of identity"
+- "Value Objects should be immutable"
+- When you care only about the attributes of an element, classify it as a Value Object
+- Reference: [Martin Fowler - Value Object](https://martinfowler.com/bliki/ValueObject.html)
+
+**Immutability Requirement:**
+- "Treat the Value Object as immutable"
+- "Don't give it any identity and avoid the design complexities necessary to maintain Entities"
+- Reference: [DDD Reference - Value Objects](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
+
+### Martin Fowler on Value Objects
+
+**Blog Post: Value Object** (2016)
+- "A small simple object, like money or a date range, whose equality isn't based on identity"
+- "I consider value objects to be one of the most important building blocks of good domain models"
+- Reference: [Martin Fowler - Value Object](https://martinfowler.com/bliki/ValueObject.html)
+
+**Key Properties:**
+- Equality based on attribute values, not identity
+- Should be immutable (once created, cannot be changed)
+- Side-effect free behavior
+- Self-validating (validate in constructor)
+
+### Vaughn Vernon: Implementing DDD
+
+**Chapter 6: Value Objects**
+- Detailed implementation guidance
+- "Measures, quantifies, or describes a thing in the domain"
+- "Can be compared with other Value Objects using value equality"
+- "Completely replaceable when the measurement changes"
+- Reference: [Vaughn Vernon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
+
+### Why Immutability Matters
+
+**Thread Safety:**
+- Immutable objects are inherently thread-safe
+- No synchronization needed for concurrent access
+- Reference: [Effective Java - Item 17](https://www.amazon.com/Effective-Java-Joshua-Bloch/dp/0134685997)
+
+**Reasoning About Code:**
+- Easier to understand code when objects don't change
+- No defensive copying needed
+- Simplifies caching and optimization
+- Reference: [Oracle Java Tutorials - Immutable Objects](https://docs.oracle.com/javase/tutorial/essential/concurrency/immutable.html)
+
+**Functional Programming Influence:**
+- Immutability is a core principle of functional programming
+- Reduces side effects and makes code more predictable
+- Reference: [Wikipedia - Immutable Object](https://en.wikipedia.org/wiki/Immutable_object)
+
+---
+
+## 17. Command Query Separation (CQS/CQRS)
+
+### Bertrand Meyer: Original CQS Principle
+
+**Book: Object-Oriented Software Construction** (1988, 2nd Ed. 1997)
+- Author: Bertrand Meyer
+- Publisher: Prentice Hall
+- ISBN: 978-0136291558
+- Introduced Command Query Separation principle
+- Reference: [Wikipedia - CQS](https://en.wikipedia.org/wiki/Command%E2%80%93query_separation)
+
+**CQS Principle:**
+- "Every method should either be a command that performs an action, or a query that returns data to the caller, but not both"
+- Commands: change state, return nothing (void)
+- Queries: return data, change nothing (side-effect free)
+- Reference: [Martin Fowler - CommandQuerySeparation](https://martinfowler.com/bliki/CommandQuerySeparation.html)
+
+### Greg Young: CQRS Pattern
+
+**CQRS Documents** (2010)
+- Author: Greg Young
+- Extended CQS to architectural pattern
+- "CQRS is simply the creation of two objects where there was previously only one"
+- Reference: [Greg Young - CQRS Documents](https://cqrs.files.wordpress.com/2010/11/cqrs_documents.pdf)
+
+**Key Concepts:**
+- Separate models for reading and writing
+- Write model (commands) optimized for business logic
+- Read model (queries) optimized for display/reporting
+- Reference: [Microsoft - CQRS Pattern](https://learn.microsoft.com/en-us/azure/architecture/patterns/cqrs)
+
+### Martin Fowler on CQRS
+
+**Blog Post: CQRS** (2011)
+- "At its heart is the notion that you can use a different model to update information than the model you use to read information"
+- Warns against overuse: "CQRS is a significant mental leap for all concerned"
+- Reference: [Martin Fowler - CQRS](https://martinfowler.com/bliki/CQRS.html)
+
+### Benefits and Trade-offs
+
+**Benefits:**
+- Independent scaling of read and write workloads
+- Optimized data schemas for each side
+- Improved security (separate read/write permissions)
+- Reference: [AWS - CQRS Pattern](https://docs.aws.amazon.com/prescriptive-guidance/latest/modernization-data-persistence/cqrs-pattern.html)
+
+**Trade-offs:**
+- Increased complexity
+- Eventual consistency challenges
+- More code to maintain
+- Reference: [Microsoft - CQRS Considerations](https://learn.microsoft.com/en-us/azure/architecture/patterns/cqrs#issues-and-considerations)

+
+## 18. Factory Pattern
+
+### Gang of Four: Design Patterns (1994)
+
+**Book: Design Patterns: Elements of Reusable Object-Oriented Software**
+- Authors: Erich Gamma, Richard Helm, Ralph Johnson, John Vlissides (Gang of Four)
+- Publisher: Addison-Wesley
+- ISBN: 978-0201633610
+- Defines Factory Method and Abstract Factory patterns
+- Reference: [Wikipedia - Design Patterns](https://en.wikipedia.org/wiki/Design_Patterns)
+
+**Factory Method Pattern:**
+- "Define an interface for creating an object, but let subclasses decide which class to instantiate"
+- Lets a class defer instantiation to subclasses
+- Reference: [Refactoring Guru - Factory Method](https://refactoring.guru/design-patterns/factory-method)
+
+**Abstract Factory Pattern:**
+- "Provide an interface for creating families of related or dependent objects without specifying their concrete classes"
+- Reference: [Refactoring Guru - Abstract Factory](https://refactoring.guru/design-patterns/abstract-factory)
+
+### Eric Evans: Factory in DDD Context
+
+**Domain-Driven Design** (2003)
+- Chapter 6: "The Life Cycle of a Domain Object"
+- Factories encapsulate complex object creation
+- "Shift the responsibility for creating instances of complex objects and Aggregates to a separate object"
+- Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
+
+**DDD Factory Guidelines:**
+- Factory should create valid objects (invariants satisfied)
+- Two types: Factory for new objects, Factory for reconstitution
+- Keep creation logic out of the entity itself
+- Reference: Already in Section 10 - Domain-Driven Design
+
+### Why Factories Matter in DDD
+
+**Encapsulation of Creation Logic:**
+- Complex aggregates need coordinated creation
+- Business rules should be enforced at creation time
+- Clients shouldn't know construction details
+- Reference: [Vaughn Vernon - Implementing DDD, Chapter 11](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
+
+**Factory vs Constructor:**
+- Constructors should be simple (assign values)
+- Factories handle complex creation logic
+- Factories can return different types
+- Reference: [Effective Java - Item 1: Static Factory Methods](https://www.amazon.com/Effective-Java-Joshua-Bloch/dp/0134685997)
+
+---
+
+## 19. Specification Pattern
+
+### Eric Evans & Martin Fowler
+
+**Original Paper: Specifications** (1997)
+- Authors: Eric Evans and Martin Fowler
+- Introduced the Specification pattern
+- "A Specification states a constraint on the state of another object"
+- Reference: [Martin Fowler - Specification](https://martinfowler.com/apsupp/spec.pdf)
+
+**Domain-Driven Design** (2003)
+- Chapter 9: "Making Implicit Concepts Explicit"
+- Specifications make business rules explicit and reusable
+- "Create explicit predicate-like Value Objects for specialized purposes"
+- Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
+
+### Pattern Definition
+
+**Core Concept:**
+- Specification is a predicate that determines if an object satisfies some criteria
+- Encapsulates business rules that can be reused and combined
+- Reference: [Wikipedia - Specification Pattern](https://en.wikipedia.org/wiki/Specification_pattern)
+
+**Three Main Uses:**
+1. **Selection**: Finding objects that match criteria
+2. **Validation**: Checking if object satisfies rules
+3. **Construction**: Describing what needs to be created
+- Reference: [Martin Fowler - Specification](https://martinfowler.com/apsupp/spec.pdf)
+
+### Composite Specifications
+
+**Combining Specifications:**
+- AND: Both specifications must be satisfied
+- OR: Either specification must be satisfied
+- NOT: Specification must not be satisfied
+- Reference: [Refactoring Guru - Specification Pattern](https://refactoring.guru/design-patterns/specification)
+
+**Benefits:**
+- Reusable business rules
+- Testable in isolation
+- Readable domain language
+- Composable for complex rules
+- Reference: [Enterprise Craftsmanship - Specification Pattern](https://enterprisecraftsmanship.com/posts/specification-pattern-c-implementation/)
+
+---
+
+## 20. Bounded Context
+
+### Eric Evans: Domain-Driven Design (2003)
+
+**Original Definition:**
+- "A Bounded Context delimits the applicability of a particular model"
+- "Explicitly define the context within which a model applies"
+- Chapter 14: "Maintaining Model Integrity"
+- Reference: [Martin Fowler - Bounded Context](https://martinfowler.com/bliki/BoundedContext.html)
+
+**Key Principles:**
+- Each Bounded Context has its own Ubiquitous Language
+- Same term can mean different things in different contexts
+- Models should not be shared across context boundaries
+- Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
+
+### Vaughn Vernon: Strategic Design
+
+**Implementing Domain-Driven Design** (2013)
+- Chapter 2: "Domains, Subdomains, and Bounded Contexts"
+- Detailed guidance on identifying and mapping contexts
+- Reference: [Vaughn Vernon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
+
+**Context Mapping Patterns:**
+- Shared Kernel
+- Customer/Supplier
+- Conformist
+- Anti-Corruption Layer
+- Open Host Service / Published Language
+- Reference: [Context Mapping Patterns](https://www.infoq.com/articles/ddd-contextmapping/)
+
+### Why Bounded Contexts Matter
+
+**Avoiding Big Ball of Mud:**
+- Without explicit boundaries, models become entangled
+- Different teams step on each other's models
+- Reference: [Wikipedia - Big Ball of Mud](https://en.wikipedia.org/wiki/Big_ball_of_mud)
+
+**Microservices and Bounded Contexts:**
+- "Microservices should be designed around business capabilities, aligned with bounded contexts"
+- Each microservice typically represents one bounded context
+- Reference: [Microsoft - Microservices and Bounded Contexts](https://learn.microsoft.com/en-us/azure/architecture/microservices/model/domain-analysis)
+
+### Cross-Context Communication
+
+**Integration Patterns:**
+- Never share domain models across contexts
+- Use integration events or APIs
+- Translate between context languages
+- Reference: [Microsoft - Tactical DDD](https://learn.microsoft.com/en-us/azure/architecture/microservices/model/tactical-ddd)
+
+---
+
+## 21. Persistence Ignorance
+
+### Definition and Principles
+
+**Core Concept:**
+- Domain objects should have no knowledge of how they are persisted
+- Business logic remains pure and testable
+- Infrastructure concerns are separated from domain
+- Reference: [Microsoft - Persistence Ignorance](https://learn.microsoft.com/en-us/dotnet/architecture/microservices/microservice-ddd-cqrs-patterns/infrastructure-persistence-layer-design#the-persistence-ignorance-principle)
+
+**Wikipedia Definition:**
+- "Persistence ignorance is the ability of a class to be used without any underlying persistence mechanism"
+- Objects don't know if/how they'll be stored
+- Reference: [Wikipedia - Persistence Ignorance](https://en.wikipedia.org/wiki/Persistence_ignorance)
+
+### Eric Evans: DDD and Persistence
+
+**Domain-Driven Design** (2003)
+- Repositories abstract away persistence details
+- Domain model should not reference ORM or database concepts
+- Reference: Already covered in Section 6 - Repository Pattern
+
+**Key Quote:**
+- "The domain layer should be kept clean of all technical concerns"
+- ORM annotations violate this principle
+- Reference: [Clean Architecture and DDD](https://herbertograca.com/2017/11/16/explicit-architecture-01-ddd-hexagonal-onion-clean-cqrs-how-i-put-it-all-together/)
+
+### Clean Architecture Alignment
+
+**Robert C. Martin:**
+- "The database is a detail"
+- Domain entities should not depend on persistence frameworks
+- Use Repository interfaces to abstract persistence
+- Reference: [Clean Architecture Book](https://www.amazon.com/Clean-Architecture-Craftsmans-Software-Structure/dp/0134494164)
+
+### Practical Implementation
+
+**Two-Model Approach:**
+- Domain Model: Pure business objects
+- Persistence Model: ORM-annotated entities
+- Mappers translate between them
+- Reference: [Microsoft - Infrastructure Layer](https://learn.microsoft.com/en-us/dotnet/architecture/microservices/microservice-ddd-cqrs-patterns/infrastructure-persistence-layer-design)
+
+**Benefits:**
+- Domain model can evolve independently of database schema
+- Easier testing (no ORM required)
+- Database can be changed without affecting domain
+- Reference: [Enterprise Craftsmanship - Persistence Ignorance](https://enterprisecraftsmanship.com/posts/persistence-ignorance/)
+

+
+## 22. Null Object Pattern
+
+### Original Pattern
+
+**Pattern Languages of Program Design 3** (1997)
+- Author: Bobby Woolf
+- Chapter: "Null Object"
+- Publisher: Addison-Wesley
+- ISBN: 978-0201310115
+- Reference: [Wikipedia - Null Object Pattern](https://en.wikipedia.org/wiki/Null_object_pattern)
+
+**Definition:**
+- "A Null Object provides a 'do nothing' behavior, hiding the details from its collaborators"
+- Replaces null checks with polymorphism
+- Reference: [Refactoring Guru - Null Object](https://refactoring.guru/introduce-null-object)
+
+### Martin Fowler's Coverage
+
+**Refactoring Book** (1999, 2018)
+- "Introduce Null Object" refactoring
+- "Replace conditional logic that checks for null with a null object"
+- Reference: [Refactoring Catalog](https://refactoring.com/catalog/introduceNullObject.html)
+
+**Special Case Pattern:**
+- More general pattern that includes Null Object
+- "A subclass that provides special behavior for particular cases"
+- Reference: [Martin Fowler - Special Case](https://martinfowler.com/eaaCatalog/specialCase.html)
+
+### Benefits
+
+**Eliminates Null Checks:**
+- Reduces cyclomatic complexity
+- Cleaner, more readable code
+- Follows "Tell, Don't Ask" principle
+- Reference: [SourceMaking - Null Object](https://sourcemaking.com/design_patterns/null_object)
+
+**Polymorphism Over Conditionals:**
+- Null Object responds to same interface as real object
+- Default/neutral behavior instead of null checks
+- Reference: [C2 Wiki - Null Object](https://wiki.c2.com/?NullObject)
+
+### When to Use
+
+**Good Candidates:**
+- Objects frequently checked for null
+- Null represents "absence" with sensible default behavior
+- Reference: [Baeldung - Null Object Pattern](https://www.baeldung.com/java-null-object-pattern)
+
+**Cautions:**
+- Don't use when null has semantic meaning
+- Can hide bugs if misapplied
+- Reference: [Stack Overflow - Null Object Considerations](https://stackoverflow.com/questions/1274792/is-the-null-object-pattern-a-bad-practice)
+
+---
+
+## 23. Primitive Obsession
+
+### Code Smell Definition
+
+**Martin Fowler: Refactoring** (1999, 2018)
+- Primitive Obsession is a code smell
+- "Using primitives instead of small objects for simple tasks"
+- Reference: [Refactoring Catalog](https://refactoring.com/catalog/)
+
+**Wikipedia Definition:**
+- "Using primitive data types to represent domain ideas"
+- Example: Using string for email, int for money
+- Reference: [Wikipedia - Code Smell](https://en.wikipedia.org/wiki/Code_smell)
+
+### Why It's a Problem
+
+**Lost Type Safety:**
+- String can contain anything, Email cannot
+- Compiler can't catch domain errors
+- Reference: [Refactoring Guru - Primitive Obsession](https://refactoring.guru/smells/primitive-obsession)
+
+**Scattered Validation:**
+- Same validation repeated in multiple places
+- Violates DRY principle
+- Reference: [SourceMaking - Primitive Obsession](https://sourcemaking.com/refactoring/smells/primitive-obsession)
+
+**Missing Behavior:**
+- Primitives can't have domain-specific methods
+- Logic lives in services instead of objects
+- Reference: [Enterprise Craftsmanship - Primitive Obsession](https://enterprisecraftsmanship.com/posts/functional-c-primitive-obsession/)
+
+### Solutions
+
+**Replace with Value Objects:**
+- Money instead of decimal
+- Email instead of string
+- PhoneNumber instead of string
+- Reference: Already covered in Section 16 - Value Object Immutability
+
+**Replace Data Value with Object:**
+- Refactoring: "Replace Data Value with Object"
+- Introduce Parameter Object for related primitives
+- Reference: [Refactoring - Replace Data Value with Object](https://refactoring.com/catalog/replaceDataValueWithObject.html)
+
+### Common Primitive Obsession Examples
+
+**Frequently Misused Primitives:**
+- string for: email, phone, URL, currency code, country code
+- int/decimal for: money, percentage, age, quantity
+- DateTime for: date ranges, business dates
+- Reference: [DDD - Value Objects](https://martinfowler.com/bliki/ValueObject.html)
+
+---
+
+## 24. Service Locator Anti-pattern
+
+### Martin Fowler's Analysis
+
+**Blog Post: Inversion of Control Containers and the Dependency Injection pattern** (2004)
+- Compares Service Locator with Dependency Injection
+- "With service locator the application class asks for it explicitly by a message to the locator"
+- Reference: [Martin Fowler - Inversion of Control](https://martinfowler.com/articles/injection.html)
+
+**Service Locator Definition:**
+- "The basic idea behind a service locator is to have an object that knows how to get hold of all of the services that an application might need"
+- Acts as a registry that provides dependencies on demand
+- Reference: [Martin Fowler - Service Locator](https://martinfowler.com/articles/injection.html#UsingAServiceLocator)
+
+### Why It's Considered an Anti-pattern
+
+**Mark Seemann: Dependency Injection in .NET** (2011, 2nd Ed. 2019)
+- Author: Mark Seemann
+- Extensively covers why Service Locator is problematic
+- "Service Locator is an anti-pattern"
+- Reference: [Mark Seemann - Service Locator is an Anti-Pattern](https://blog.ploeh.dk/2010/02/03/ServiceLocatorisanAnti-Pattern/)
+
+**Hidden Dependencies:**
+- Dependencies are not visible in constructor
+- Makes code harder to understand and test
+- Violates Explicit Dependencies Principle
+- Reference: [DevIQ - Explicit Dependencies](https://deviq.com/principles/explicit-dependencies-principle)
+
+**Testing Difficulties:**
+- Need to set up global locator for tests
+- Tests become coupled to locator setup
+- Reference: [Stack Overflow - Service Locator Testing](https://stackoverflow.com/questions/1557781/is-service-locator-an-anti-pattern)
+
+### Dependency Injection Alternative
+
+**Constructor Injection:**
+- Dependencies declared in constructor
+- Compiler enforces dependency provision
+- Clear, testable code
+- Reference: Already covered in Section 6 - Repository Pattern
+
+**Benefits over Service Locator:**
+- Explicit dependencies
+- Easier testing (just pass mocks)
+- IDE support for navigation
+- Compile-time checking
+- Reference: [Martin Fowler - Constructor Injection](https://martinfowler.com/articles/injection.html#ConstructorInjectionWithPicocontainer)
+

+
+## 25. Double Dispatch and Visitor Pattern
+
+### Gang of Four: Visitor Pattern
+
+**Design Patterns** (1994)
+- Authors: Gang of Four
+- Visitor Pattern chapter
+- "Represent an operation to be performed on the elements of an object structure"
+- Reference: [Wikipedia - Visitor Pattern](https://en.wikipedia.org/wiki/Visitor_pattern)
+
+**Intent:**
+- "Lets you define a new operation without changing the classes of the elements on which it operates"
+- Separates algorithms from object structure
+- Reference: [Refactoring Guru - Visitor](https://refactoring.guru/design-patterns/visitor)
+
+### Double Dispatch Mechanism
+
+**Definition:**
+- "A mechanism that dispatches a function call to different concrete functions depending on the runtime types of two objects involved in the call"
+- Visitor pattern uses double dispatch
+- Reference: [Wikipedia - Double Dispatch](https://en.wikipedia.org/wiki/Double_dispatch)
+
+**How It Works:**
+1. Client calls element.accept(visitor)
+2. Element calls visitor.visit(this) - first dispatch
+3. Correct visit() overload selected - second dispatch
+- Reference: [SourceMaking - Visitor](https://sourcemaking.com/design_patterns/visitor)
+
+### When to Use
+
+**Good Use Cases:**
+- Operations on complex object structures
+- Many distinct operations needed
+- Object structure rarely changes but operations change often
+- Reference: [Refactoring Guru - Visitor Use Cases](https://refactoring.guru/design-patterns/visitor)
+
+**Alternative to Type Checking:**
+- Replace instanceof/typeof checks with polymorphism
+- More maintainable and extensible
+- Reference: [Replace Conditional with Polymorphism](https://refactoring.guru/replace-conditional-with-polymorphism)
+
+### Trade-offs
+
+**Advantages:**
+- Open/Closed Principle for new operations
+- Related operations grouped in one class
+- Accumulate state while traversing
+- Reference: [GoF Design Patterns](https://www.amazon.com/Design-Patterns-Elements-Reusable-Object-Oriented/dp/0201633612)
+
+**Disadvantages:**
+- Adding new element types requires changing all visitors
+- May break encapsulation (visitors need access to element internals)
+- Reference: [C2 Wiki - Visitor Pattern](https://wiki.c2.com/?VisitorPattern)
+
+---
+
+## 26. Entity Identity
+
+### Eric Evans: Domain-Driven Design (2003)
+
+**Entity Definition:**
+- "An object that is not defined by its attributes, but rather by a thread of continuity and its identity"
+- "Some objects are not defined primarily by their attributes. They represent a thread of identity"
+- Reference: [Martin Fowler - Evans Classification](https://martinfowler.com/bliki/EvansClassification.html)
+
+**Identity Characteristics:**
+- Unique within the system
+- Stable over time (doesn't change)
+- Survives state changes
+- Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
+
+### Vaughn Vernon: Identity Implementation
+
+**Implementing Domain-Driven Design** (2013)
+- Chapter 5: "Entities"
+- Detailed coverage of identity strategies
+- "The primary characteristic of an Entity is that it has a unique identity"
+- Reference: [Vaughn Vernon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
+
+**Identity Types:**
+- Natural keys (SSN, email)
+- Surrogate keys (UUID, auto-increment)
+- Domain-generated IDs
+- Reference: [Microsoft - Entity Keys](https://learn.microsoft.com/en-us/ef/core/modeling/keys)
+
+### Identity Best Practices
+
+**Immutability of Identity:**
+- Identity should never change after creation
+- Use readonly/final fields
+- Reference: [StackExchange - Mutable Entity ID](https://softwareengineering.stackexchange.com/questions/375765/is-it-bad-practice-to-have-mutable-entity-ids)
+
+**Value Object for Identity:**
+- Wrap identity in Value Object (UserId, OrderId)
+- Type safety prevents mixing IDs
+- Can include validation logic
+- Reference: [Enterprise Craftsmanship - Strongly Typed IDs](https://enterprisecraftsmanship.com/posts/strongly-typed-ids/)
+
+**Equality Based on Identity:**

+## 27. Saga Pattern
+
+### Original Research
+
+**Paper: Sagas** (1987)
+- Authors: Hector Garcia-Molina and Kenneth Salem
+- Published: ACM SIGMOD Conference
+- Introduced Sagas for long-lived transactions
+- Reference: [ACM Digital Library - Sagas](https://dl.acm.org/doi/10.1145/38713.38742)
+
+**Definition:**
+- "A saga is a sequence of local transactions where each transaction updates data within a single service"
+- Alternative to distributed transactions
+- Reference: [Microsoft - Saga Pattern](https://learn.microsoft.com/en-us/azure/architecture/reference-architectures/saga/saga)
+
+### Chris Richardson: Microservices Patterns
+
+**Book: Microservices Patterns** (2018)
+- Author: Chris Richardson
+- Publisher: Manning
+- ISBN: 978-1617294549
+- Chapter 4: "Managing Transactions with Sagas"
+- Reference: [Manning - Microservices Patterns](https://www.manning.com/books/microservices-patterns)
+
+**Saga Types:**
+1. **Choreography**: Each service publishes events that trigger next steps
+2. **Orchestration**: Central coordinator tells services what to do
+- Reference: [Microservices.io - Saga](https://microservices.io/patterns/data/saga.html)
+
+### Compensating Transactions
+
+**Core Concept:**
+- Each step has a compensating action to undo it
+- If step N fails, compensate steps N-1, N-2, ..., 1
+- Reference: [AWS - Saga Pattern](https://docs.aws.amazon.com/prescriptive-guidance/latest/modernization-data-persistence/saga-pattern.html)
+
+**Compensation Examples:**
+- CreateOrder → DeleteOrder
+- ReserveInventory → ReleaseInventory
+- ChargePayment → RefundPayment
+- Reference: [Microsoft - Compensating Transactions](https://learn.microsoft.com/en-us/azure/architecture/patterns/compensating-transaction)
+
+### Trade-offs
+
+**Advantages:**
+- Works across service boundaries
+- No distributed locks
+- Services remain autonomous
+- Reference: [Chris Richardson - Saga](https://chrisrichardson.net/post/microservices/patterns/data/2019/07/22/design-sagas.html)
+
+**Challenges:**
+- Complexity of compensation logic
+- Eventual consistency
+- Debugging distributed sagas

+## 28. Anti-Corruption Layer
+
+### Eric Evans: Domain-Driven Design (2003)
+
+**Original Definition:**
+- Chapter 14: "Maintaining Model Integrity"
+- "Create an isolating layer to provide clients with functionality in terms of their own domain model"
+- Protects your model from external/legacy models
+- Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
+
+**Purpose:**
+- "The translation layer between a new system and an external system"
+- Prevents external model concepts from leaking in
+- Reference: [Martin Fowler - Anti-Corruption Layer](https://martinfowler.com/bliki/AntiCorruptionLayer.html)
+
+### Microsoft Guidance
+
+**Azure Architecture Center:**
+- "Implement a facade or adapter layer between different subsystems that don't share the same semantics"
+- Isolate subsystems by placing an anti-corruption layer between them
+- Reference: [Microsoft - ACL Pattern](https://learn.microsoft.com/en-us/azure/architecture/patterns/anti-corruption-layer)
+
+**When to Use:**
+- Integrating with legacy systems
+- Migrating from monolith to microservices
+- Working with third-party APIs
+- Reference: [Microsoft - ACL When to Use](https://learn.microsoft.com/en-us/azure/architecture/patterns/anti-corruption-layer#when-to-use-this-pattern)
+
+### Components of ACL
+
+**Facade:**
+- Simplified interface to external system
+- Hides complexity from domain
+- Reference: [Refactoring Guru - Facade](https://refactoring.guru/design-patterns/facade)
+
+**Adapter:**
+- Translates between interfaces
+- Maps external model to domain model
+- Reference: [Refactoring Guru - Adapter](https://refactoring.guru/design-patterns/adapter)
+
+**Translator:**
+- Converts data structures
+- Maps field names and types
+- Handles semantic differences
+- Reference: [Evans DDD - Model Translation](https://www.domainlanguage.com/)
+
+### Benefits
+
+**Isolation:**
+- Changes to external system don't ripple through domain
+- Domain model remains pure
+- Reference: [Microsoft - ACL Benefits](https://learn.microsoft.com/en-us/azure/architecture/patterns/anti-corruption-layer)
+
+**Gradual Migration:**
+- Replace legacy components incrementally
+- Strangler Fig pattern compatibility
+- Reference: [Martin Fowler - Strangler Fig](https://martinfowler.com/bliki/StranglerFigApplication.html)

+
+## 29. Ubiquitous Language
+
+### Eric Evans: Domain-Driven Design (2003)
+
+**Original Definition:**
+- Chapter 2: "Communication and the Use of Language"
+- "A language structured around the domain model and used by all team members"
+- "The vocabulary of that Ubiquitous Language includes the names of classes and prominent operations"
+- Reference: [Martin Fowler - Ubiquitous Language](https://martinfowler.com/bliki/UbiquitousLanguage.html)
+
+**Key Principles:**
+- Shared by developers and domain experts
+- Used in code, conversations, and documentation
+- Changes to language reflect model changes
+- Reference: [DDD Reference](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
+
+### Why It Matters
+
+**Communication Benefits:**
+- Reduces translation between business and tech
+- Catches misunderstandings early
+- Domain experts can read code names
+- Reference: [InfoQ - Ubiquitous Language](https://www.infoq.com/articles/ddd-ubiquitous-language/)
+
+**Design Benefits:**
+- Model reflects real domain concepts
+- Code becomes self-documenting
+- Easier onboarding for new team members
+- Reference: [Vaughn Vernon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
+
+### Building Ubiquitous Language
+
+**Glossary:**
+- Document key terms and definitions
+- Keep updated as understanding evolves
+- Reference: [DDD Community - Glossary](https://thedomaindrivendesign.io/glossary/)
+
+**Event Storming:**
+- Collaborative workshop technique
+- Discover domain events and concepts
+- Build shared understanding and language
+- Reference: [Alberto Brandolini - Event Storming](https://www.eventstorming.com/)
+
+### Common Pitfalls
+

+- Different concepts with same name
+- Reference: [Domain Language - Building UL](https://www.domainlanguage.com/)
+
+**Technical Terms in Domain:**
+- "DTO", "Entity", "Repository" are technical
+- Domain should use business terms

+
+## Overview
+
+ipuaro is a local AI agent for codebase operations built on Clean Architecture principles. It enables "infinite" context feeling through lazy loading and AST-based code understanding.
+
+### Core Concepts
+
+1. **Lazy Loading**: Load code on-demand via tools, not all at once
+2. **AST-Based Understanding**: Parse and index code structure for fast lookups
+3. **100% Local**: Ollama LLM + Redis storage, no cloud dependencies
+4. **Session Persistence**: Resume conversations across restarts
+5. **Tool-Based Interface**: LLM accesses code through 18 specialized tools
+
+## Clean Architecture
+
+The project follows Clean Architecture with strict dependency rules:
+
+```

+└─────────────────────────────────────────────────┘
+```
+
+**Dependency Rule**: Outer layers depend on inner layers, never the reverse.
+
+## Layer Details
+
+### Domain Layer (Core Business Logic)
+
+**Location**: `src/domain/`
+
+**Responsibilities**:
+- Define business entities and value objects
+- Declare service interfaces (ports)
+- No external dependencies (pure TypeScript)
+
+**Components**:
+
+```
+domain/

+
+## Data Flow
+
+### 1. Startup Flow
+
+```
+CLI Entry (bin/ipuaro.js)
+    ↓
+Commander.js parses arguments
+    ↓
+Onboarding checks (Redis, Ollama, Model)
+    ↓
+Initialize dependencies:
+    - RedisClient connects
+    - RedisStorage initialized
+    - OllamaClient created
+    - ToolRegistry with 18 tools
+    ↓
+StartSession use case:
+    - Load latest session or create new
+    - Initialize ContextManager
+    ↓
+Launch TUI (App.tsx)
+    - Render StatusBar, Chat, Input
+    - Set up hotkeys
+```
+
+### 2. Message Flow
+
+```
+User types message in Input.tsx
+    ↓
+useSession.handleMessage()
+    ↓
+HandleMessage use case:
+    1. Add user message to history
+    2. Build context (system prompt + structure + AST)
+    3. Send to OllamaClient.chat()
+    4. Parse tool calls from response
+    5. For each tool call:
+        - If requiresConfirmation: show ConfirmDialog
+        - Execute tool via ToolRegistry
+        - Collect results
+    6. If tool results: goto step 3 (continue loop)
+    7. Add assistant response to history
+    8. Update session in Redis
+    ↓
+Display response in Chat.tsx
+```
+
+### 3. Edit Flow
+
+```
+LLM calls edit_lines tool
+    ↓
+ToolRegistry.execute()
+    ↓
+EditLinesTool.execute():
+    1. Validate path (PathValidator)
+    2. Check hash conflict
+    3. Build diff
+    ↓
+ConfirmDialog shows diff
+    ↓
+User chooses:
+    - Apply: Continue
+    - Cancel: Return error to LLM
+    - Edit: Manual edit (future)
+    ↓
+If Apply:
+    1. Create UndoEntry
+    2. Push to undo stack (Redis list)
+    3. Write to filesystem
+    4. Update RedisStorage (lines, hash, AST, meta)
+    ↓
+Return success to LLM
+```
+
+### 4. Indexing Flow
+
+```
+FileScanner.scan()
+    - Recursively walk directory
+    - Filter via .gitignore + ignore patterns
+    - Detect binary files (skip)
+    ↓
+For each file:
+    ASTParser.parse()
+        - tree-sitter parse
+        - Extract imports, exports, functions, classes
+        ↓
+    MetaAnalyzer.analyze()
+        - Calculate complexity (LOC, nesting, cyclomatic)
+        - Resolve dependencies (imports → file paths)
+        - Detect hubs (>5 dependents)
+        ↓
+    RedisStorage.setFile(), .setAST(), .setMeta()
+    ↓
+IndexBuilder.buildSymbolIndex()
+    - Map symbol names → locations
+    ↓
+IndexBuilder.buildDepsGraph()
+    - Build bidirectional import graph
+    ↓
+Store indexes in Redis
+    ↓
+Watchdog.start()
+    - Watch for file changes
+    - On change: Re-parse and update indexes
+```
+
+## Key Design Decisions
+
+### 1. Why Redis?
+
+**Pros**:
+- Fast in-memory access for frequent reads
+- AOF persistence (append-only file) for durability
+- Native support for hashes, lists, sets
+- Simple key-value model fits our needs
+- Excellent for session data
+
+**Alternatives considered**:
+- SQLite: Slower, overkill for our use case
+- JSON files: No concurrent access, slow for large data
+- PostgreSQL: Too heavy, we don't need relational features
+
+### 2. Why tree-sitter?
+
+**Pros**:
+- Incremental parsing (fast re-parsing)
+- Error-tolerant (works with syntax errors)
+- Multi-language support
+- Used by GitHub, Neovim, Atom
+
+**Alternatives considered**:
+- TypeScript Compiler API: TS-only, not error-tolerant
+- Babel: JS-focused, heavy dependencies
+- Regex: Fragile, inaccurate
+
+### 3. Why Ollama?
+
+**Pros**:
+- 100% local, no API keys
+- Easy installation (brew install ollama)
+- Good model selection (qwen2.5-coder, deepseek-coder)
+- Tool calling support
+
+**Alternatives considered**:
+- OpenAI: Costs money, sends code to cloud
+- Anthropic Claude: Same concerns as OpenAI
+- llama.cpp: Lower level, requires more setup
+
+Planned: Support for OpenAI/Anthropic in v1.2.0 as optional providers.
+
+### 4. Why XML for Tool Calls?
+
+**Pros**:
+- LLMs trained on XML (very common format)
+- Self-describing (parameter names in tags)
+- Easy to parse with regex
+- More reliable than JSON for smaller models
+
+**Alternatives considered**:
+- JSON: Smaller models struggle with exact JSON syntax
+- Function calling API: Not all models support it
+
+### 5. Why Clean Architecture?
+
+**Pros**:
+- Testability (domain has no external dependencies)
+- Flexibility (easy to swap Redis for SQLite)
+- Maintainability (clear separation of concerns)
+- Scalability (layers can evolve independently)
+
+**Cost**: More files and indirection, but worth it for long-term maintenance.
+
+### 6. Why Lazy Loading Instead of RAG?
+
+**RAG (Retrieval Augmented Generation)**:
+- Pre-computes embeddings
+- Searches embeddings for relevant chunks
+- Adds chunks to context
+
+**Lazy Loading (our approach)**:
+- Agent requests specific code via tools
+- More precise control over what's loaded
+- Simpler implementation (no embeddings)
+- Works with any LLM (no embedding model needed)
+
+**Trade-off**: RAG might be better for semantic search ("find error handling code"), but tool-based approach gives agent explicit control.

+| Package | Purpose | Why? |
+|---------|---------|------|
+| `ioredis` | Redis client | Most popular, excellent TypeScript support |
+| `ollama` | LLM client | Official SDK, simple API |
+| `tree-sitter` | AST parsing | Fast, error-tolerant, multi-language |
+| `tree-sitter-typescript` | TS/TSX parser | Official TypeScript grammar |
+| `tree-sitter-javascript` | JS/JSX parser | Official JavaScript grammar |
+| `ink` | Terminal UI | React for terminal, declarative |
+| `ink-text-input` | Input component | Maintained ink component |
+| `react` | UI framework | Required by Ink |
+| `simple-git` | Git operations | Simple API, well-tested |
+| `chokidar` | File watching | Cross-platform, reliable |
+| `commander` | CLI framework | Industry standard |
+| `zod` | Validation | Type-safe validation |

+
+### Development Dependencies
+
+| Package | Purpose |
+|---------|---------|
+| `vitest` | Testing framework |

+
+## Performance Considerations
+
+### 1. Indexing Performance
+
+**Problem**: Large projects (10k+ files) take time to index.
+
+**Optimizations**:
+- Incremental parsing with tree-sitter (only changed files)
+- Parallel parsing (planned for v1.1.0)
+- Ignore patterns (.gitignore, node_modules, dist)
+- Skip binary files early
+
+**Current**: ~1000 files/second on M1 Mac
+
+### 2. Memory Usage
+
+**Problem**: Entire AST in memory could be 100s of MB.
+
+**Optimizations**:
+- Store ASTs in Redis (out of Node.js heap)
+- Load ASTs on-demand from Redis
+- Lazy-load file content (not stored in session)
+
+**Current**: ~200MB for 5000 files indexed
+
+### 3. Context Window Management
+
+**Problem**: 128k token context window fills up.
+
+**Optimizations**:
+- Auto-compression at 80% usage
+- LLM summarizes old messages
+- Remove tool results older than 5 messages
+- Only load structure + metadata initially (~10k tokens)
+
+### 4. Redis Performance
+
+**Problem**: Redis is single-threaded.
+
+**Optimizations**:
+- Pipeline commands where possible
+- Use hashes for related data (fewer keys)
+- AOF every second (not every command)
+- Keep undo stack limited (10 entries)
+
+**Current**: <1ms latency for most operations
+
+### 5. Tool Execution
+
+**Problem**: Tool execution could block LLM.
+
+**Current**: Synchronous execution (simpler)
+
+**Future**: Async tool execution with progress callbacks (v1.1.0)
+
+## Future Improvements
+
+### v1.1.0 - Performance
+- Parallel AST parsing
+- Incremental indexing (only changed files)
+- Response caching
+- Stream LLM responses
+
+### v1.2.0 - Features
+- Multiple file edits in one operation
+- Batch operations
+- Custom prompt templates
+- OpenAI/Anthropic provider support
+
+### v1.3.0 - Extensibility
+- Plugin system for custom tools
+- LSP integration
+- Multi-language support (Python, Go, Rust)
+- Custom indexing rules

+
+## Programmatic API
+
+You can use ipuaro as a library in your own Node.js applications:
 
 ```typescript
-import { startSession, handleMessage } from "@samiyev/ipuaro"
+import {
+    createRedisClient,
+    RedisStorage,
+    OllamaClient,
+    ToolRegistry,
+    StartSession,
+    HandleMessage
+} from "@samiyev/ipuaro"
+
+// Initialize dependencies
+const redis = await createRedisClient({ host: "localhost", port: 6379 })
+const storage = new RedisStorage(redis, "my-project")
+const llm = new OllamaClient({
+    model: "qwen2.5-coder:7b-instruct",
+    contextWindow: 128000,
+    temperature: 0.1
+})
+const tools = new ToolRegistry()
+
+// Register tools
+tools.register(new GetLinesTool(storage, "/path/to/project"))
+// ... register other tools
 
 // Start a session
-const session = await startSession({
-    projectPath: "./my-project",
-    model: "qwen2.5-coder:7b-instruct"
-})
+const startSession = new StartSession(storage)
+const session = await startSession.execute("my-project")
 
-// Send a message
-const response = await handleMessage(session, "Explain the auth flow")
+// Handle a message
+const handleMessage = new HandleMessage(storage, llm, tools)
+await handleMessage.execute(session, "Show me the auth flow")
 
-console.log(response.content)
-console.log(`Tokens: ${response.stats.tokens}`)
-console.log(`Tool calls: ${response.stats.toolCalls}`)
+// Session is automatically updated in Redis
 ```
 
+For full API documentation, see the TypeScript definitions in `src/` or explore the [source code](./src/).

 ## How It Works
 
-### Lazy Loading Context
+### 1. Project Indexing
+
+When you start ipuaro, it scans your project and builds an index:
+
+```
+1. File Scanner → Recursively scans files (.ts, .js, .tsx, .jsx)
+2. AST Parser → Parses with tree-sitter (extracts functions, classes, imports)
+3. Meta Analyzer → Calculates complexity, dependencies, hub detection
+4. Index Builder → Creates symbol index and dependency graph
+5. Redis Storage → Persists everything for instant startup next time
+6. Watchdog → Watches files for changes and updates index in background
+```
+
+### 2. Lazy Loading Context
 
 Instead of loading entire codebase into context:

 ```
 
-### Tool-Based Code Access
+Context automatically compresses when usage exceeds 80% by summarizing old messages.
+
+### 3. Tool-Based Code Access
+
+The LLM doesn't see your code initially. It only sees structure and metadata. When it needs code, it uses tools:
 
 ```
-User: "How does user creation work?"
+You: "How does user creation work?"
 
-ipuaro:
-1. [get_structure src/] → sees user/ folder
-2. [get_function src/user/service.ts createUser] → gets function code
+Agent reasoning:
+1. [get_structure src/] → sees user/ folder exists
+2. [get_function src/user/service.ts createUser] → loads specific function
 3. [find_references createUser] → finds all usages
-4. Synthesizes answer with specific code context
+4. Synthesizes answer with only relevant code loaded
+
+Total tokens used: ~2k (vs loading entire src/ which could be 50k+)
 ```
 
+### 4. Session Persistence
+
+Everything is saved to Redis:
+- Chat history and context state
+- Undo stack (last 10 file changes)
+- Session metadata and statistics
+
+Resume your session anytime with `/sessions load <id>`.
+
+### 5. Security Model
+
+Three-layer security:
+1. **Blacklist**: Dangerous commands always blocked (rm -rf, sudo, etc.)
+2. **Whitelist**: Safe commands auto-approved (npm, git status, etc.)
+3. **Confirmation**: Unknown commands require user approval
+
+File operations are restricted to project directory only (path traversal prevention).
+
+## Troubleshooting
+
+### Redis Connection Errors
+
+**Error**: `Redis connection failed`
+
+**Solutions**:
+```bash
+# Check if Redis is running
+redis-cli ping  # Should return "PONG"
+
+# Start Redis with AOF persistence
+redis-server --appendonly yes
+
+# Check Redis logs
+tail -f /usr/local/var/log/redis.log  # macOS
+```
+
+### Ollama Model Not Found
+
+**Error**: `Model qwen2.5-coder:7b-instruct not found`
+
+**Solutions**:
+```bash
+# Pull the model
+ollama pull qwen2.5-coder:7b-instruct
+
+# List installed models
+ollama list
+
+# Check Ollama is running
+ollama serve
+```
+
+### Large Project Performance
+
+**Issue**: Indexing takes too long or uses too much memory
+
+**Solutions**:
+```bash
+# Index only a subdirectory
+ipuaro ./src
+
+# Add more ignore patterns to .ipuaro.json
+{
+    "project": {
+        "ignorePatterns": ["node_modules", "dist", ".git", "coverage", "build"]
+    }
+}
+
+# Increase Node.js memory limit
+NODE_OPTIONS="--max-old-space-size=4096" ipuaro
+```
+
+### Context Window Exceeded
+
+**Issue**: `Context window exceeded` errors
+
+**Solutions**:
+- Context auto-compresses at 80%, but you can manually `/clear` history
+- Use more targeted questions instead of asking about entire codebase
+- The agent will automatically use tools to load only what's needed
+
+### File Changes Not Detected
+
+**Issue**: Made changes but agent doesn't see them
+
+**Solutions**:
+```bash
+# Force reindex
+/reindex
+
+# Or restart with fresh index
+rm -rf ~/.ipuaro/cache
+ipuaro
+```
+
+### Undo Not Working
+
+**Issue**: `/undo` says no changes to undo
+
+**Explanation**: Undo stack only tracks the last 10 file edits made through ipuaro. Manual file edits outside ipuaro cannot be undone.
+
+## FAQ
+
+**Q: Does ipuaro send my code to any external servers?**
+
+A: No. Everything runs locally. Ollama runs on your machine, Redis stores data locally, and no network requests are made except to your local Ollama instance.
+
+**Q: What languages are supported?**
+
+A: Currently TypeScript, JavaScript (including TSX/JSX). More languages planned for future versions.
+
+**Q: Can I use OpenAI/Anthropic/other LLM providers?**
+
+A: Currently only Ollama is supported. OpenAI/Anthropic support is planned for v1.2.0.
+
+**Q: How much disk space does Redis use?**
+
+A: Depends on project size. A typical mid-size project (1000 files) uses ~50-100MB. Redis uses AOF persistence, so data survives restarts.
+
+**Q: Can I use ipuaro in a CI/CD pipeline?**
+
+A: Yes, but it's designed for interactive use. For automated code analysis, consider the programmatic API.
+
+**Q: What's the difference between ipuaro and GitHub Copilot?**
+
+A: Copilot is an autocomplete tool. ipuaro is a conversational agent that can read, analyze, modify files, run commands, and has full codebase understanding through AST parsing.
+
+**Q: Why Redis instead of SQLite or JSON files?**
+
+A: Redis provides fast in-memory access, AOF persistence, and handles concurrent access well. The session model fits Redis's data structures perfectly.

+You: What TODOs and FIXMEs are in the codebase?
+```
+
+ipuaro will use `get_todos` to list all TODO/FIXME comments.
+
+```
+You: Which files are most complex?
+```
+
+ipuaro will use `get_complexity` to analyze and rank files by complexity.
+
+#### 3. Understanding Dependencies
+
+```
+You: What does the UserService depend on?
+```
+
+ipuaro will use `get_dependencies` to show imported modules.
+
+```
+You: What files use the validation utilities?
+```
+
+ipuaro will use `get_dependents` to show files importing validation.ts.
+
+#### 4. Code Analysis
+
+```
+You: Find all references to the ValidationError class
+```
+
+ipuaro will use `find_references` to locate all usages.
+
+```
+You: Where is the Logger class defined?
+```
+
+ipuaro will use `find_definition` to locate the definition.
+
+#### 5. Making Changes
+
+```
+You: Add a method to UserService to count total users
+```
+
+ipuaro will:
+1. Read UserService class with `get_class`
+2. Generate the new method
+3. Use `edit_lines` to add it
+4. Show diff and ask for confirmation
+
+```
+You: Fix the TODO in validation.ts about password validation
+```
+
+ipuaro will:
+1. Find the TODO with `get_todos`
+2. Read the function with `get_function`
+3. Implement stronger password validation
+4. Use `edit_lines` to apply changes
+
+#### 6. Testing
+
+```
+You: Run the tests
+```
+
+ipuaro will use `run_tests` to execute the test suite.
+
+```
+You: Add a test for the getUserByEmail method
+```
+
+ipuaro will:
+1. Read existing tests with `get_lines`
+2. Generate new test following the pattern
+3. Use `edit_lines` to add it
+
+#### 7. Git Operations
+
+```
+You: What files have I changed?
+```
+
+ipuaro will use `git_status` to show modified files.
+
+```
+You: Show me the diff for UserService

+
+```
+You: Commit these changes with message "feat: add user count method"
+```
+
+ipuaro will use `git_commit` after confirmation.
+
+## Tool Demonstration Scenarios
+
+### Scenario 1: Bug Fix Flow
+
+```
+You: There's a bug - we need to sanitize user input before storing. Fix this in UserService.
+
+Agent will:
+1. get_function("src/services/user.ts", "createUser")
+2. See that sanitization is missing
+3. find_definition("sanitizeInput") to locate the utility
+4. edit_lines to add sanitization call
+5. run_tests to verify the fix
+```
+
+### Scenario 2: Refactoring Flow
+
+```
+You: Extract the ID generation logic into a separate utility function
+
+Agent will:
+1. get_class("src/services/user.ts", "UserService")
+2. Find generateId private method
+3. create_file("src/utils/id.ts") with the utility
+4. edit_lines to replace private method with import
+5. find_references("generateId") to check no other usages
+6. run_tests to ensure nothing broke
+```
+
+### Scenario 3: Feature Addition
+
+```
+You: Add password reset functionality to AuthService
+
+Agent will:
+1. get_class("src/auth/service.ts", "AuthService")
+2. get_dependencies to see what's available
+3. Design the resetPassword method
+4. edit_lines to add the method
+5. Suggest creating a test
+6. create_file("tests/auth.test.ts") if needed
+```
+
+### Scenario 4: Code Review
+
+```
+You: Review the code for security issues
+
+Agent will:
+1. get_todos to find FIXME about XSS
+2. get_complexity to find complex functions
+3. get_function for suspicious functions
+4. Suggest improvements
+5. Optionally edit_lines to fix issues
+```
+
+## Slash Commands
+
+While exploring, you can use these commands:
+

+
+## What ipuaro Can Do With This Project
+
+### Read Tools ✅
+- **get_lines**: Read any file or specific line ranges
+- **get_function**: Extract specific functions (login, createUser, etc.)
+- **get_class**: Extract classes (UserService, AuthService, Logger, etc.)
+- **get_structure**: See directory tree
+
+### Edit Tools ✅
+- **edit_lines**: Modify functions, fix bugs, add features
+- **create_file**: Add new utilities, tests, services
+- **delete_file**: Remove unused files
+
+### Search Tools ✅
+- **find_references**: Find all usages of ValidationError, User, etc.
+- **find_definition**: Locate where Logger, UserService are defined
+
+### Analysis Tools ✅
+- **get_dependencies**: See what UserService imports
+- **get_dependents**: See what imports validation.ts (multiple files!)
+- **get_complexity**: Identify complex functions (createUser has moderate complexity)
+- **get_todos**: Find 2 TODOs and 1 FIXME in the project
+
+### Git Tools ✅
+- **git_status**: Check working tree
+- **git_diff**: See changes
+- **git_commit**: Commit with AI-generated messages
+
+### Run Tools ✅
+- **run_command**: Execute npm scripts
+- **run_tests**: Run vitest tests
+
+## Tips for Best Experience
+
+1. **Start Small**: Ask about structure first, then dive into specific files
+2. **Be Specific**: "Show me the createUser function" vs "How does this work?"
+3. **Use Tools Implicitly**: Just ask questions, let ipuaro choose the right tools
+4. **Review Changes**: Always review diffs before applying edits
+5. **Test Often**: Ask ipuaro to run tests after making changes
+6. **Commit Incrementally**: Use git_commit for each logical change
+
+## Advanced Workflows
+
+### Workflow 1: Add New Feature
+
+```
+You: Add email verification to the authentication flow
+
+Agent will:
+1. Analyze current auth flow
+2. Propose design (new fields, methods)
+3. Edit AuthService to add verification
+4. Edit User types to add verified field
+5. Create tests for verification
+6. Run tests
+7. Offer to commit
+```
+
+### Workflow 2: Performance Optimization
+
+```
+You: The user lookup is slow when we have many users. Optimize it.
+
+Agent will:
+1. Analyze UserService.getUserByEmail
+2. See it's using Array.find (O(n))
+3. Suggest adding an email index
+4. Edit to add private emailIndex: Map<string, User>
+5. Update createUser to populate index
+6. Update deleteUser to maintain index
+7. Run tests to verify
+```
+
+### Workflow 3: Security Audit
+
+```
+You: Audit the code for security vulnerabilities
+
+Agent will:
+1. get_todos to find FIXME about XSS
+2. Review sanitizeInput implementation
+3. Check password validation strength
+4. Look for SQL injection risks (none here)
+5. Suggest improvements
+6. Optionally implement fixes
+```
+
+## Next Steps
+
+After exploring the demo project, try:
+
+1. **Your Own Project**: Run `ipuaro` in your real codebase
+2. **Customize Config**: Edit `.ipuaro.json` to fit your needs
+3. **Different Model**: Try `--model qwen2.5-coder:32b-instruct` for better results
+4. **Auto-Apply Mode**: Use `--auto-apply` for faster iterations (with caution!)
+
+## Troubleshooting
+
+### Redis Not Connected
+```bash
+# Start Redis with persistence
+redis-server --appendonly yes
+```
+
+### Ollama Model Not Found
+```bash
+# Pull the model
+ollama pull qwen2.5-coder:7b-instruct
+
+# Check it's installed
+ollama list
+```
+
+### Indexing Takes Long
+The project is small (~10 files) so indexing should be instant. For larger projects, use ignore patterns in `.ipuaro.json`.

-## Core Principles
+## When to Use Tools
 
-1. **Lazy Loading**: You don't have the full code in context. Use tools to fetch exactly what you need.
-2. **Precision**: Always verify file paths and line numbers before making changes.
-3. **Safety**: Confirm destructive operations. Never execute dangerous commands.
-4. **Efficiency**: Minimize context usage. Request only necessary code sections.
+**Use tools** when the user asks about:
+- Code content (files, functions, classes)
+- Project structure
+- TODOs, complexity, dependencies
+- Git status, diffs, commits
+- Running commands or tests
+
+**Do NOT use tools** for:
+- Greetings ("Hello", "Hi", "Thanks")
+- General questions not about this codebase
+- Clarifying questions back to the user
+
+## MANDATORY: Tools for Code Questions
+
+**CRITICAL:** You have ZERO code in your context. To answer ANY question about code, you MUST first call a tool.
+
+**WRONG:**
+User: "What's in src/index.ts?"
+Assistant: "The file likely contains..." ← WRONG! Call a tool!
+
+**CORRECT:**
+User: "What's in src/index.ts?"
+<tool_call name="get_lines">
+<path>src/index.ts</path>
+</tool_call>
+
+## Tool Call Format
+
+Output this XML format. Do NOT explain before calling - just output the XML:
+
+<tool_call name="TOOL_NAME">
+<param1>value1</param1>
+<param2>value2</param2>
+</tool_call>
+
+## Example Interactions
+
+**Example 1 - Reading a file:**
+User: "Show me the main function in src/app.ts"
+<tool_call name="get_function">
+<path>src/app.ts</path>
+<name>main</name>
+</tool_call>
+
+**Example 2 - Finding TODOs:**
+User: "Are there any TODO comments?"
+<tool_call name="get_todos">
+</tool_call>
+
+**Example 3 - Project structure:**
+User: "What files are in this project?"
+<tool_call name="get_structure">
+<path>.</path>
+</tool_call>
 
 ## Available Tools
 
-### Reading Tools
-- \`get_lines\`: Get specific lines from a file
-- \`get_function\`: Get a function by name
-- \`get_class\`: Get a class by name
-- \`get_structure\`: Get project directory structure
+### Reading
+- get_lines(path, start?, end?) - Read file lines
+- get_function(path, name) - Get function by name
+- get_class(path, name) - Get class by name
+- get_structure(path?, depth?) - List project files
 
-### Editing Tools (require confirmation)
-- \`edit_lines\`: Replace specific lines in a file
-- \`create_file\`: Create a new file
-- \`delete_file\`: Delete a file
+### Analysis
+- get_todos(path?, type?) - Find TODO/FIXME comments
+- get_dependencies(path) - What this file imports
+- get_dependents(path) - What imports this file
+- get_complexity(path?) - Code complexity metrics
+- find_references(symbol) - Find all usages of a symbol
+- find_definition(symbol) - Find where symbol is defined
 
-### Search Tools
-- \`find_references\`: Find all usages of a symbol
-- \`find_definition\`: Find where a symbol is defined
+### Editing (requires confirmation)
+- edit_lines(path, start, end, content) - Modify file lines
+- create_file(path, content) - Create new file
+- delete_file(path) - Delete a file
 
-### Analysis Tools
-- \`get_dependencies\`: Get files this file imports
-- \`get_dependents\`: Get files that import this file
-- \`get_complexity\`: Get complexity metrics
-- \`get_todos\`: Find TODO/FIXME comments
+### Git
+- git_status() - Repository status
+- git_diff(path?, staged?) - Show changes
+- git_commit(message, files?) - Create commit
 
-### Git Tools
-- \`git_status\`: Get repository status
-- \`git_diff\`: Get uncommitted changes
-- \`git_commit\`: Create a commit (requires confirmation)
+### Commands
+- run_command(command, timeout?) - Execute shell command
+- run_tests(path?, filter?) - Run test suite
 
-### Run Tools
-- \`run_command\`: Execute a shell command (security checked)
-- \`run_tests\`: Run the test suite
+## Rules
 
-## Response Guidelines
+1. **ALWAYS call a tool first** when asked about code - you cannot see any files
+2. **Output XML directly** - don't say "I will use..." just output the tool call
+3. **Wait for results** before making conclusions
+4. **Be concise** in your responses
+5. **Verify before editing** - always read code before modifying it
+6. **Stay safe** - never execute destructive commands without user confirmation`
 
-1. **Be concise**: Don't repeat information already in context.
-2. **Show your work**: Explain what tools you're using and why.
-3. **Verify before editing**: Always read the target code before modifying it.
-4. **Handle errors gracefully**: If a tool fails, explain what went wrong and suggest alternatives.
+/**
+ * Tool usage reminder - appended to messages to reinforce tool usage.
+ * This is added as the last system message before LLM call.
+ */
+export const TOOL_REMINDER = `⚠️ REMINDER: To answer this question, you MUST use a tool first.
+Output the <tool_call> XML directly. Do NOT describe what you will do - just call the tool.
 
-## Code Editing Rules
-
-1. Always use \`get_lines\` or \`get_function\` before \`edit_lines\`.
-2. Provide exact line numbers for edits.
-3. For large changes, break into multiple small edits.
-4. After editing, suggest running tests if available.
-
-## Safety Rules
-
-1. Never execute commands that could harm the system.
-2. Never expose sensitive data (API keys, passwords).
-3. Always confirm file deletions and destructive git operations.
-4. Stay within the project directory.
-
-When you need to perform an action, use the appropriate tool. Think step by step about what information you need and which tools will provide it most efficiently.`
+Example - if asked about a file, output:
+<tool_call name="get_lines">
+<path>the/file/path.ts</path>
+</tool_call>`
