What does this agent skill do?

codebase-design

What it does

codebase-design turns the DDD shape into an implementation contract for the codebase. It decides which packages, seams, adapters, tests, and files change, without reopening the DDD decisions themselves.

Inputs

  • Architecture Spec
  • ddd-design output
  • code-research summary
  • effective-java-notes.md when writing Java

Package layout

The default Java package shape is:

ui
app
domain
infra
  • ui holds outward-facing entry points and presentation adapters.
  • app holds orchestration application services only.
  • app is the transaction boundary.
  • domain holds entities, value objects, domain methods, domain services, aggregates, and domain policies.
  • infra holds adapters that implement ports.

Process

  1. Translate the event-storming policy output into unit-testable behavior.
  2. Keep domain behavior in domain methods or domain services.
  3. Model aggregate relationships through entity IDs, not through broad object graphs.
  4. Put orchestration-only application services in app.
  5. Put port implementations and external-system adapters in infra.
  6. Map the minimum set of files, modules, interfaces, seams, and tests needed to realize the design.
  7. Consult effective-java-notes.md before writing Java code.

Completion

  • The code structure is concrete enough to implement.
  • Domain decisions are not re-litigated here.
  • The package shape stays ui / app / domain / infra.
  • The transaction boundary stays in app.
  • Policy behavior is covered by unit tests.
