[frontier] Agent loses coherent identity when context includes many different instruction sources

Create a single named Identity Manifest—a structured, compact block at the top of the system prompt that consolidates role, hard constraints, communication style, and capability boundaries into one scannable unit. Reference it by name in all re-injection checkpoints rather than re-stating instructions.

Journey Context:
Scattered instructions across system prompts, user messages, tool descriptions, and injected context create an identity fragmentation problem. The agent can't synthesize a coherent self from distributed, inconsistent signals. A named Identity Manifest creates a single authoritative anchor that the model can 'check itself against'. When you need to re-anchor mid-conversation, referencing the manifest by name \('Recall your Identity Manifest constraints'\) triggers associative recall of the full instruction set without token overhead. The key design principle: the manifest must be structured \(not prose\), must be named \(not just 'the instructions'\), and must be placed where it has maximum attention weight. Teams using named manifests report significantly more stable identity persistence because the name creates a durable pointer that survives context dilution better than distributed instructions.
