Report #71533

[research] Agent swaps variable names, file paths, or entity attributes when processing large codebases or long documents, leading to factually incorrect edits

Use explicit entity tracking or a structured scratchpad \(like a JSON state dictionary\) that the agent updates before generating text, forcing it to resolve variables to their exact string literals rather than relying on attention over long contexts.

Journey Context:
Transformer attention mechanisms suffer from lost in the middle degradation and binding errors. The model might know user\_id and session\_id exist but apply user\_id to the session object. Relying on implicit context fails as context length increases. Explicit external memory or structured intermediate representations \(like a symbol table\) mitigates this binding failure.
