name: sea-dsl-authoring description: Author SEA-DSL specifications with proper CQRS annotations, validation, and namespace conventions. Use when creating .sea files with entities, flows, and policies that require @cqrs, @tx, @outbox, and @idempotency annotations following the Flow-only CQRS tagging pattern.

SEA-DSL Authoring Skill

Guides users through authoring semantically valid SEA-DSL files.

Prerequisites

Before authoring SEA-DSL, understand:

• SEA-DSL grammar from sea_dsl_language_reference.yml
• CQRS annotation requirements from flow_lint.py
• Namespace conventions and bounded context boundaries

Workflow

1. Draft: Create .sea file with proper namespacing
2. Annotate: Add required annotations to all Flows
3. Validate: Run just sea-validate <file>
4. Parse: Run just sea-parse <file> to generate AST
5. Lint: Run just flow-lint to verify annotations

Required Annotations

Every Flow MUST have:

Copy@cqrs { "kind": "command" | "query" | "event" }

Commands MUST have:

Copy@tx { "transactional": true | false }

Events MUST have:

Copy@outbox { "mode": "required" | "optional" }

Rules

• Use nested JSON only (no dotted keys like @cqrs.kind)
• All JSON must be valid
• Never claim success without validation passing
• Follow namespace conventions: system.<context>.<name>

Example

Copy@namespace "system.orders"
@version "1.0.0"

Entity "Order" in system.orders

Flow "CreateOrder" from "Customer" to "OrderAggregate"
  @cqrs { "kind": "command" }
  @tx { "transactional": true }
  @idempotency { "enabled": true, "key": "orderId" }
