Report #86791

[research] Agent uses deprecated methods or syntax from its training data cutoff, ignoring the current version specified by the user

Check the \`pyproject.toml\`, \`package.json\`, or \`requirements.txt\` to identify the exact version of dependencies before writing code, and rely on retrieved up-to-date documentation rather than parametric memory.

Journey Context:
A model trained up to 2022 might use \`sklearn.cross\_validation\` instead of \`sklearn.model\_selection\`. Parametric memory is stale. Grounding the agent in the project's explicit dependency files and using web search/retrieval for current docs bridges the temporal gap.
