[frontier] Agent acknowledges constraints verbally but violates them in output over long sessions

Require the agent to paraphrase its top 3 active constraints in its own words at natural checkpoints—task start, before implementation, before commit. This 'constraint echo' forces active processing and creates a self-generated commitment in context that is more resistant to decay than externally-stated instructions.

Journey Context:
Stating a constraint in the system prompt creates weak anchoring because the agent processes it passively. Having the agent paraphrase the constraint creates strong anchoring because: \(1\) it forces active processing rather than passive recognition, \(2\) the paraphrased version enters context as the agent's own output, which receives higher self-attention weight, and \(3\) it makes violations detectable as self-contradictions rather than just instruction violations. This is analogous to the generation effect in human memory: people remember information better when they generate it themselves. The tradeoff is token cost and slight verbosity, but the improvement in constraint adherence is significant. Leading teams report 2-3x improvement in constraint adherence with constraint echoing vs. system-prompt-only constraint declaration.
