[agent\_craft] Single agent accumulates all context for a multi-step task, causing attention dilution and context overflow

Decompose complex tasks into scoped subagents using an orchestrator-worker pattern. Each worker receives only the context it needs for its subtask. Workers return results and summaries to the orchestrator, not full context. The orchestrator maintains the plan and high-level state only.

Journey Context:
A single agent working on 'refactor the auth module and update all tests' accumulates context from every subtask: auth module code, test files, database schema, error logs. By the time it's writing tests, its context is full of auth internals irrelevant to test authoring. This causes attention dilution — the model spreads attention across all prior context rather than focusing on what matters now. The orchestrator-worker pattern solves this: a lightweight orchestrator maintains the plan and spawns scoped workers. Each worker gets focused context \(the file to modify, the specific error, the instruction\). Workers return summaries, not full context. The tradeoff is orchestration overhead and potential loss of cross-subtask insights \(a worker won't know what another worker discovered\). Mitigate by having the orchestrator pass relevant discoveries between workers via structured handoff messages. For complex multi-file tasks, the focused-attention benefit far outweighs the orchestration cost.
