[frontier] Multi-agent swarms converge to 'session average' personality, losing specialized agent identity \(swarm homogenization\)

Use 'Cryptographic Identity Anchors' with MCP server metadata: assign each agent a UUID-bound system prompt stored as an MCP resource with a hash verification step. Before each response, the agent must quote the first 8 characters of its identity hash, forcing explicit retrieval of distinct identity from external state rather than implicit context absorption.

Journey Context:
In long multi-agent sessions, implicit training on shared conversation history causes 'personality diffusion' where agents mimic the dominant voice. Simple system prompts fail because the shared context window acts as a homogenizing force. Drawing from Constitutional AI's use of explicit principle statements and MCP's resource isolation, the fix creates an 'identity externalization' pattern. By requiring a cryptographic proof-of-identity \(the hash quote\) before generation, you force the model to actively retrieve its distinct persona from MCP state, creating a hard boundary that resists the ambient drift of the conversation.
