From 8876349deccaba1d4ba4f2ccf45bd40bafca1fbb Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Fri, 24 Apr 2026 01:02:10 +0000 Subject: [PATCH] fix(action): add default value type validation to ActionArgumentSchema Added @model_validator(mode="after") to ActionArgumentSchema that validates default value type against declared type field. Supports all argument types: string, integer, float, boolean, list. Handles edge cases: None defaults (always valid), bool vs int disambiguation (bool checked before int since bool is a subclass of int), float widening from int. Added @a2a @domain @action tags to the BDD feature file. Reordered step definitions so specific patterns match before generic ones. Added CHANGELOG and CONTRIBUTORS entries. Moved model_config before validators per Pydantic convention.
