Report #101847
[frontier] Agent context gets polluted with exploration noise from deep tool calls and never recovers focus
Use sub-agent architectures: delegate focused exploration to specialized workers with clean context windows, and have the lead agent keep only a high-level plan plus 1-2k token summaries. This isolates search context from decision context and prevents a single window from accumulating irrelevant tool outputs.
Journey Context:
One agent cannot simultaneously maintain a project-wide plan and execute deep technical exploration. Anthropic's multi-agent research system showed substantial gains by keeping detailed search context inside sub-agents while the lead agent synthesizes summaries. The pattern is now native in Claude Code subagents and is the scaling answer to context pollution.
