Report #28643

[synthesis] Agent confidently writes code using deprecated or non-existent API parameters, leading to cascading syntax errors

Inject current, version-pinned documentation into the context before writing code, rather than relying on parametric memory. Use a documentation retrieval tool \(RAG\) scoped to the project dependencies.

Journey Context:
LLMs have broad but shallow knowledge of library APIs. They often conflate versions \(e.g., using React Router v5 syntax in a v6 project, or Pydantic v1 in v2\). When the code fails, the error message is often ambiguous, leading the agent to fix it by trying another wrong parameter from a different version, creating a cascade of failures. The tradeoff is the cost of a RAG call vs. the risk of hallucination. For core dependencies, RAG is always worth it.
