Report #55932

[research] Agent writes code using features or syntax from a newer version of a language/framework than the target environment supports

Explicitly inject the target environment's exact version numbers into the system prompt and retrieve version-specific documentation via RAG rather than relying on generalized parametric memory.

Journey Context:
Training data contains code from multiple versions of languages \(e.g., Python 3.8 vs 3.12\). LLMs will happily mix syntax, like using \`match\` statements in Python 3.9. Parametric memory cannot reliably segregate features by version. Grounding the agent in version-specific documentation forces it to only use features available in the actual execution environment.
