Report #80567

[frontier] Agent remembers how to use tools but forgets permission constraints after 50 turns

Decouple constraints from the prompt. Move constraint enforcement to deterministic, pre-execution guardrails \(e.g., a validation layer\) rather than relying on the LLM to remember them from the system prompt.

Journey Context:
LLMs encode capabilities \(API syntax\) robustly in their weights but treat textual constraints as soft preferences that decay over context length. Putting constraints in the prompt is merely a suggestion; putting them in a runtime hook is a law. This prevents the 'reckless tool use' drift where capability remains but governance evaporates.
