Report #98449

[research] Model produces outdated or hallucinated package names, API signatures, or version details

For code-related facts, do not trust parametric memory. Use live tool calls: package registry APIs, documentation search, or deterministic execution. Prefer ReAct-style reasoning-acting loops that retrieve up-to-date evidence.

Journey Context:
Code ecosystems evolve rapidly, making parametric knowledge stale. Toolformer \(Schick et al., 2023\) and ReAct \(Yao et al., 2023\) showed that models can use external tools to ground claims in live data. For coding agents, this translates to looking up docs, running tests, and querying package indexes rather than guessing API details.
