[frontier] Agent loses track of its operational mode during long multi-phase sessions

Require the agent to begin each response with a mode tag: \[MODE: security-review\]. Define 3-5 valid modes in the system prompt with distinct behavioral expectations. The act of generating the mode tag forces the agent to re-assert its identity before generating content. Mode tags must have behavioral consequences — e.g., \[MODE: security-review\] requires a security checklist in the response.

Journey Context:
This pattern exploits a quirk of autoregressive generation: the first tokens of a response strongly influence all subsequent tokens via causal attention. By forcing the agent to generate a mode tag first, you make it prime itself with the correct operational context on every turn. This is more reliable than passive mode indicators in the system prompt because the agent must actively produce the tag, creating a self-reinforcing identity loop. The tradeoff is slight output verbosity and the risk of the tag becoming decorative rather than functional. Tags become decorative when they have no behavioral consequence — the agent learns to generate the tag then ignore it. The fix: each mode tag must require mode-specific behavior in the response body, making the tag a commitment device not just a label.
