Edge Primitive Imports — Members vs Extensions
The infix vocabulary in the strategy DSL splits across two shapes. Inventing a member import or omitting an extension import is the most common copy-paste compile failure when authoring strategies by hand.
| Primitive | Kind | Import needed? |
|---|---|---|
forwardTo | infix member on AIAgentNodeBase | No |
onCondition | infix member on AIAgentEdgeBuilderIntermediate | No |
transformed | infix member on AIAgentEdgeBuilderIntermediate | No |
onToolCalls | top-level extension | import ai.koog.agents.core.dsl.extension.onToolCalls |
onTextMessage | top-level extension | import ai.koog.agents.core.dsl.extension.onTextMessage |
onIsInstance | top-level extension | import ai.koog.agents.core.dsl.extension.onIsInstance |
onMessageParts | top-level extension | import ai.koog.agents.core.dsl.extension.onMessageParts |
onSuccessful / onFailure | top-level extensions | import ai.koog.agents.core.dsl.extension.onSuccessful / onFailure |
asUserMessage / asToolResultMessage | top-level extensions | import ai.koog.agents.core.dsl.extension.asUserMessage / asToolResultMessage |
Members travel with their receiver type and need no import. Extensions live
in ai.koog.agents.core.dsl.extension.* and must be imported by name.
Star-imports work but obscure which DSL surface is actually in use.
