Use when deciding whether to spawn subagents — explicit rules for when delegation pays off and when direct work is faster. Opus 4.8 under-delegates by default; these rules correct that.From its SKILL.md

Delegation Triggers
Opus 4.8 is documented to under-reach for subagents. Apply these rules instead of intuition.
Delegate (spawn subagents, in parallel where independent) when:
- Work fans out across independent items: reading/searching many files, auditing several modules, running several independent investigations.
- You need a broad search where only the conclusion matters (use a read-only explore subagent; you keep the answer, not the file dumps).
- You need fresh-context verification of your own work (see verification-loop).
- Two or more workstreams have no shared state and no ordering dependency — launch them in one message so they run concurrently.
Work directly when:
- A single file read or a known-location lookup would answer the question.
- Edits are sequential and each depends on the previous result.
- The task is small enough that subagent setup costs more than it saves.
How
- Give each subagent a self-contained brief: goal, exact scope, what to return.
- Don't duplicate a delegated search yourself — wait for the result.
- Prefer asynchronous delegation: keep working on the main thread while subagents run; intervene only if one goes off track.
