Report #85858

[frontier] Agent remembers how to do things but forgets what NOT to do over long sessions

Reframe all constraints as positive capabilities using 'instead of X, do Y' patterns. Replace 'never use raw SQL queries' with 'all database access goes through the ORM layer in src/db/orm.py.' Constraints stated as negations decay 2-3x faster than those stated as positive actions.

Journey Context:
This asymmetry exists because capabilities are reinforced by the model's training data — it has seen millions of examples of raw SQL. Constraints stated as negations \('don't do X'\) compete directly against this training prior, and in long sessions the prior wins as attention to the negation fades. Positive-action constraints \('do Y'\) leverage the same mechanism: the model is equally good at following positive instructions as exercising capabilities. The 'instead of' pattern is critical because it gives the model an alternative action path; without it, the model may avoid the negated behavior but produce degraded output because it has no clear replacement. This pattern emerged from production agent deployments in 2024-2025 where teams observed negation-based constraints failing first and most catastrophically in long sessions.
