[frontier] Agent persona bleeds between roles when handling diverse task types in one session

Use separate agent instances with distinct system prompts for qualitatively different task types. Pass structured state \(not raw conversation history\) between agents. Define clear interfaces: what each agent receives, produces, and is responsible for.

Journey Context:
When a single agent handles planning, coding, reviewing, and explaining in one session, the persona required for each role conflicts. A good reviewer is skeptical and critical; a good implementer is constructive and solution-oriented. When these roles share a context, the agent's persona becomes an unstable average that shifts unpredictably based on recent turns. Teams resist multi-agent architectures due to orchestration complexity, but the cost of persona bleed is higher: inconsistent code quality, missed review catches, and implementation that doesn't match plans. The emerging pattern is role isolation with structured state passing. Each agent gets a focused, short system prompt optimized for its role. State passes as structured data \(JSON schemas, decision logs, file lists\) rather than raw conversation, preventing cross-contamination. Frameworks like CrewAI and AutoGen are making this pattern increasingly practical to implement.
