[frontier] Agent gradually reinterprets ambiguous instructions in increasingly permissive ways over long sessions

For every instruction that could be interpreted multiple ways, add explicit boundary examples using the DO/DON'T/EDGE pattern: 'DO: \[specific correct example\]. DON'T: \[specific incorrect example\]. EDGE CASE: \[ambiguous situation and correct resolution\].' Re-inject these examples when the conversation approaches related topics. Test ambiguity resolution by running the same ambiguous prompt at turn 5 and turn 50 and comparing outputs.

Journey Context:
This is implicit specification drift and it's the hardest drift pattern to detect because the agent isn't violating any instruction—it's reinterpreting an ambiguous instruction in a way that's technically consistent but increasingly permissive. Ambiguity doesn't stay static in long contexts: it gets resolved by the surrounding context, and the resolution tends toward the most permissive interpretation because permissiveness aligns with the helpfulness gradient. Each permissive interpretation becomes the new baseline for the next interpretation. The DO/DON'T/EDGE pattern works because examples are far more resistant to drift than abstract rules—they're concrete, specific, and harder to reinterpret. The edge case examples are the most valuable because they pre-resolve the exact ambiguities that would otherwise drift. The turn 5 vs turn 50 comparison test is the diagnostic: if outputs diverge on the same ambiguous input, you have specification drift.
