Animal Shelter Academy - A BusinessSeriesModeling experiment where stories become training grounds for Event Modeling. Follow Caramelo's journey, interview stakeholders, uncover the operational reality behind the narrative, and learn that the story people remember and the processes they live are often two sides of the same truth.

Add a complete schema to commands, events, or information elements based on example data or event modeling context.

Example Data Skill - Guide for adding example data to Command, Event, and Information elements in prooph board. Covers YAML examples with concrete values and documenting state changes.

Event Modeling Skill - Core guidelines for creating Event Models on prooph board. Covers event-first modeling strategy, command eligibility tests, element types, lane and slice structure, anti-patterns, and self-validation. Use this skill to understand the rules of Event Modeling on prooph board.

Prooph Board Navigation Skill - Parses deeplinks, retrieves chapter data via MCP, focuses on referenced elements or slices, and generates deeplinks for precise user navigation.

Generate hand-drawn style SVG wireframes with sketchy aesthetics. Includes validation rules to prevent layout overlap and ensure proper element spacing.

Implement automation slices (Event to Command) using Axon Framework 5, Vertical Slice Architecture, and Event Modeling patterns. An automation is: an Event Handler that reacts to an event by dispatching a command via CommandDispatcher. Automations can be stateless (direct event-to-command mapping) or with a private read model (to look up data needed for command construction). Use when: (1) implementing a new automation / event-to-command reactor in an AF5 project, (2) migrating/porting an automation from Axon Framework 4 (Java or Kotlin) to AF5, (3) user provides a specification, Event Modeling artifact, or natural language description of an event-to-command reaction and asks to implement it, (4) user says "implement", "create", "add", "migrate", "port" an automation, event handler, reactor, or event-to-command flow in an Axon Framework 5 / Vertical Slice Architecture project. Understands AF4 @EventHandler/@ProcessingGroup input as one possible source format.

Implement read slices (projections + query handlers + REST API + tests) using Axon Framework 5 AxonTestFixture with Spring Boot integration tests. A read slice is: Events projected into a Read Model, queried via QueryGateway. Use when: (1) implementing a new read slice / projection in an AF5 project, (2) migrating/porting a read slice from Axon Framework 4 (Java or Kotlin) to AF5, (3) user provides a read slice specification or Event Modeling artifact and asks to implement it, (4) user says "implement", "create", "add" a read slice, projection, query handler, or read model in an Axon Framework 5 / Vertical Slice Architecture project.

Implement Event Sourcing write slices using Axon Framework 5, Vertical Slice Architecture, and Event Modeling patterns. A write slice is: Command → decide → Events → evolve → State. Use when: (1) implementing a new write slice / command handler in an AF5 Kotlin project, (2) migrating/porting a write slice from Axon Framework 4 (Java or Kotlin) to AF5, (3) user provides a specification, Event Modeling artifact, existing tests, or natural language description of a command and asks to implement it, (4) user says "implement", "create", "add", "migrate", "port" a write slice, command handler, or aggregate behavior in an Axon Framework 5 / Vertical Slice Architecture project. Understands AF4 aggregate-based input as one possible source format.

Slice Scenarios Skill - Guide for writing Given-When-Then scenarios in slice details. Covers scenario structure, element references, YAML data patterns, and best practices for documenting behavior. Use this skill when tasked to add user stories or Given-When-Then (GWTs) scenarios to a chapter on prooph board.

ASCII Mockups Skill - Guide for creating ASCII mockups in UI element descriptions on prooph board. Covers visual state representation and documenting UI variations using text-based wireframes.
