Report #58730
[synthesis] Agent confidently uses deprecated library APIs that pass syntax checks but fail at runtime later
Implement a vector DB staleness metric for the agent's RAG knowledge base; force the agent to append version numbers to tool calls and validate them against live package registry APIs \(e.g., PyPI/NPM\) before writing the code.
Journey Context:
Agents relying on RAG for documentation often pull from outdated indices. They write syntactically perfect code using deprecated methods. Linting and static analysis might pass if the linter isn't configured for the exact version. The degradation is silent until deployment. The insight is that RAG retrieval confidence scores do not correlate with temporal validity. You must externalize version validation: the agent must prove the API exists in the target version, not just that it exists in the training data.
