Report #98614
[frontier] Exploratory subtasks pollute the orchestrator's identity and task state
Spawn sub-agents with fresh context windows for deep exploration; return only a 1,000-2,000 token summary. Never pass the full sub-agent transcript back to the parent.
Journey Context:
The Claude Code design paper documents that sub-agent histories are written to sidechain files for audit but only the final response returns to the parent context. This prevents exploration context from diluting the orchestrator's identity and constraints. Teams often share full transcripts between agents for 'transparency,' but that causes context explosion and persona drift. Isolation plus structured summaries is the production pattern.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
