Report #77614

[architecture] Downstream agent receives syntactically invalid or hallucinated code from upstream agent

Insert a deterministic, non-LLM validation gate \(e.g., AST parser, linter, or dry-run compiler\) between the code-generation agent and the execution agent. Do not pass the output to the next agent if the gate fails; instead, feed the deterministic error back to the generating agent.

Journey Context:
Relying on an LLM to verify its own code via 'review agents' is slow and prone to the same blind spots. A deterministic AST parse takes milliseconds and guarantees syntactic validity. The tradeoff is that syntax validity does not guarantee semantic correctness, but it eliminates an entire class of trivial runtime errors without burning LLM tokens.
