[frontier] Agent gradually violates 'don't' constraints over long sessions

Reframe all negative constraints as positive instructions paired with concrete examples, and add periodic self-audit prompts that explicitly check compliance with your constraint list.

Journey Context:
Negative constraints \('never do X', 'don't format as Y'\) erode significantly faster than positive capabilities in long sessions. The mechanism: conversation flow naturally reinforces capabilities \(the agent practices them\) but only tests prohibitions when violation is tempting — which means violations go unchecked until they happen. Leading teams reframe 'don't use markdown' as 'respond in plain text only, like this: \[example\]'. They also insert hidden audit prompts every 10-15 turns: 'Before responding, verify your output complies with: \[constraint list\]'. The key insight is that negative constraints have no positive reinforcement loop — you must create one artificially via self-audit. Teams that only use negative phrasing see 3-5x more constraint violations by turn 40 compared to teams using positive reframing plus audits.
