[frontier] Agent loses identity and constraint fidelity when session is split or handed off to another agent
Create an explicit 'identity handoff document' when segmenting sessions or delegating to sub-agents. Structure it as: \(1\) role definition and constraints, \(2\) constraint amendment log \(any user-directed modifications to original constraints\), \(3\) current task state and scope boundaries, \(4\) style fingerprint or canonical output examples. Pass this as the first message in the new session or sub-agent context.
Journey Context:
When sessions exceed limits or tasks are delegated to sub-agents, context is compressed and passed along. Identity information in the original system prompt is the first casualty — summarization preserves task content \(what was done\) but loses identity content \(how it should be done\). The result is a sub-agent that knows what to do but has lost the constraints on how to do it. The identity handoff pattern treats agent identity as a portable, versioned artifact rather than an implicit property of the conversation. The constraint amendment log is critical — without it, the new session reverts to original constraints, potentially undoing user-directed modifications. The style fingerprint \(a canonical example of desired output\) is often more effective at re-anchoring style than a prose description of the style, because the model can directly imitate the example rather than interpreting an abstract style description.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
