📝 WalkthroughWalkthroughThe AIML solver plugin transitions from a question-answering solver to a retrieval-based chatbot agent. Its base class changed from QuestionSolver to RetrievalEngine, and the single-answer method was replaced with a query method returning ranked (content, score) tuples. Dependencies and package metadata were updated to reflect the new architecture and OpenVoiceOS integration. Changes

the brain if supported). Specifically: call self.brain.ask(query), check for

ignored lang parameter if you don’t implement language switching.

query can return (None, 0.5) when the brain has no answer.
AimlBot.ask() returns None when the AIML kernel produces an empty response (Line 89-90). This propagates a None content value into the result list, which callers will not expect from a List[Tuple[str, float]] return type.
Additionally, the lang and k parameters are accepted but ignored — lang cannot switch the brain's language at query time, and k has no effect since at most one result is returned. Consider documenting this or handling them.
Proposed fix: filter out empty responses
def query(self, query: str, lang: Optional[str] = None, k: int = 3) -> List[Tuple[str, float]]:

ovos-plugin-manager PyPI latest version
💡 Result:
- Latest stable (non–pre-release) on PyPI:
2.2.0(released Jan 28, 2026) [1] - Latest pre-release on PyPI:
2.2.3a1(released Jan 30, 2026) [1]
Source: PyPI project page for ovos-plugin-manager [1]
Minimum version pinned to an alpha pre-release.
Requiring >=2.2.3a1 means downstream consumers must install a pre-release of ovos-plugin-manager. The latest stable release is only 2.2.0, so by default, pip install will fail to resolve this constraint (pre-releases are ignored unless --pre is passed or an explicit pre-release is already installed). This will cause dependency resolution failures for users.
Consider waiting for ovos-plugin-manager 2.2.3 stable to be released and then update the constraint to >=2.2.3,<3.0.0, or document that --pre is required until then.
