Smithy CLI v1.73.0

1.73.0 (2026-08-10)

Features

• Added a versioned smithy-agent-skills artifact that packages reviewable Agent
  Skills, starting with smithy-docs-navigator for navigating Smithy
  documentation. (#3209)
• Extended the @idempotent trait with optional exists and notFound
  properties to declare the errors returned when encountering unexpected
  resource states. (#3218)
• Updated CLI to use JDK 25 and AOT cache instead of AppCDS.
  (#3186)
• The RemovedOperationBinding diff event is now a NOTE instead of an ERROR
  when a service operation is moved to a resource within the same service
  closure (#3244)

Bug Fixes

• Added a cap to selector recursion depth to prevent malformed selectors
  (#3239)
• Fix duplicate search box in smithy doc page
  (#3245)
• Fixed trait code generation for shapes with an @idRef-annotated member or
  member's target, which produced uncompilable code. The generated default value
  for a member didn't respect @idRef trait on member or member's target and
  generated vanilla string literal, while generated member type is ShapeId.
  (#3214)
• Clean orphaned endpoint ruleset params after shape removal
  (#3219)
• Fix changelog action for external contributor PRs
  (#3220)

Documentation
