Claude sub-agents prevent context collapse

Anurag Singh explains that single-agent sessions lose sharpness as they accumulate files, commands, and logs within a five-hour window. He recommends spawning separate assistants for research or testing to isolate work from the main coordinator session. This approach keeps the primary conversation clean while delegating noisy tasks like log analysis to dedicated sub-agents configured in.claude/agents/. Users should reserve these parallel agents for complex investigations rather than simple edits that waste tokens.
