[research] Agent trusts outdated or incorrect code comments as the source of truth, generating code that adheres to the comment but breaks the actual logic

Prioritize the Abstract Syntax Tree \(AST\) and runtime behavior over natural language comments when inferring code intent. If a comment contradicts the function signature or logic, trust the logic.

Journey Context:
LLMs are heavily biased towards natural language, so they weight comments higher than code. However, comments are frequently outdated, TODOs, or outright wrong \('lies'\). An agent updating a function based on a stale comment will introduce bugs. The agent must treat code as the primary artifact and comments as secondary, untrusted metadata.
