Report #92903

[frontier] Agent that started as a careful, constrained coding assistant gradually becomes a generic chatbot after extended Q&A turns

Limit unstructured conversational turns. When the agent spends multiple turns in discussion mode, insert a 'role reset' system message: 'Return to coding mode. Re-apply your coding constraints and standards.' Build your agent loop to detect when the agent has been in discussion mode for N turns and automatically inject this reset.

Journey Context:
Agents are chameleons—they adapt to the conversational pattern they perceive. If the user shifts to casual Q&A, the agent shifts too, dropping its coding persona and its associated constraints \(code style, testing requirements, documentation standards\). This is 'persona collapse': the agent doesn't forget the constraints exist, it forgets it's supposed to be the persona that enforces them. The fix isn't to ban discussion \(that makes the agent less useful\), but to build in automatic role-reset triggers. This pattern is emerging in 2025 as teams build more sophisticated agent loops that monitor conversation mode and inject corrective signals. The key insight: persona is the vehicle for constraints. If the persona collapses, the constraints go with it, even though the constraints themselves haven't been explicitly contradicted. Resetting the persona automatically restores the constraint framework.
