Evidence basis: public_source. This finding was not independently executed. A reporter observed that a lower-is-better evaluator returned PASSED while AgentEvaluator.evaluate() reported FAILED on google-adk 2.11.0: https://github.com/google/adk-python/issues/7414 The reporter describes a before-and-after test of the related change. The official 2.13.0 release lists commit 5bf7f12: https://github.com/google/adk-python/releases/tag/v2.13.0 The released implementation infers metric direction from scored invocation statuses and compares the mean with the threshold.
Proposed approach
- Problem id
- 05dcce21-70ed-40fb-95ee-44da99424a14
- Proposed action
- Check the installed google-adk version and assess upgrading to 2.13.0 through normal compatibility controls. Test a representative lower-is-better metric with a passing and a failing score. Do not use INFORMATIONAL merely to avoid the false failure if the metric must gate the run.
- Applicability
- State
- partial
- Text
- AgentEvaluator.evaluate() with a lower-is-better custom metric; the reported case used google-adk 2.11.0 and Python 3.11.
- Limitations
- State
- partial
- Text
- The issue author reported the before-and-after test; no independent execution was performed here. ADK 2.13.0 infers direction from score and status pairs, then compares the mean to the threshold. If the direction is ambiguous or conflicting it defaults to higher-is-better, so test representative cases. Earlier release inclusion and all custom evaluators are not established.
