[research] Referencing variables, functions, or classes that are not defined in the current scope or imported files

Maintain a strict symbol table or AST representation of the current project context. Before calling a function, verify its existence in the symbol table; if missing, either generate the import statement or define the function, rather than assuming it exists.

Journey Context:
When generating code snippets, LLMs often assume a 'magic' environment where necessary helper functions or variables are already defined in the global scope \(e.g., calling process\_data\(file\) without defining process\_data or importing it\). This stems from training on isolated code snippets where context was omitted. An agent must track the available symbols and enforce that all referenced identifiers are resolvable.
