[frontier] Agent acknowledges constraints verbally but violates them in actual output

Require the agent to echo the top 2-3 most critical constraints in its response before producing output. Structure the response format as: 'Constraints active: \{c1\}, \{c2\}. Now proceeding: \{actual response\}'. This forces the constraint into the generation context at the position of maximum attention influence.

Journey Context:
There's a subtle but critical difference between a constraint being in the context and a constraint being in the generation context. A constraint at position 0 of a 50K-token context has very different influence than a constraint at position 49,990. The 'echo' pattern works by forcing the model to generate the constraint text right before generating the output, which means the constraint is at the position of maximum attention influence during output generation. This is different from re-injection \(which places text in the context but doesn't require the model to engage with it\) and self-verification \(which requires reasoning about constraints\). The echo is simpler and more reliable but costs tokens on every response. It's most valuable for the top 2-3 most critical constraints—echoing all constraints would be wasteful and could trigger repetition penalties. The key insight is that generated tokens have stronger influence on subsequent generation than context tokens, because the model has already 'committed' to them.
