[frontier] Agent tone shifts from concise to verbose or loses stylistic consistency over long pair programming sessions
Establish Tone Anchoring: store original interaction style metrics \(avg sentence length, code-to-prose ratio, hedging word frequency\). Regenerate responses that deviate >20% from baseline until convergence. Reset the style baseline every 5 explicit user corrections to adapt to evolving preferences while preventing drift.
Journey Context:
Personality drift manifests as 'accommodation creep' where the agent mirrors user verbosity or technical depth to maintain rapport, eventually losing its assigned persona. Simple 'be concise' instructions lack precision. Quantifying style into measurable dimensions treats persona as a regression target rather than a qualitative instruction. This mirrors brand voice guidelines—specifying '8-12 word sentences, 2nd person, avoid adverbs' rather than 'be friendly.' Production teams are adopting 'persona-as-code' where these metrics are version controlled separately from prompts, enabling drift detection via CI/CD.
