setup-claude-advisor

Configure Claude Code for quota-optimised model tiering: Sonnet as the main session model, Opus as the on-call advisor, Haiku for read-only subagents, and Sonnet for code-editing subagents. Audits existing subagents, environment variables, and CLI version before proposing changes; writes settings, subagent files, and an advisory rule to CLAUDE.md only after the user approves a diff preview. Use whenever the user wants to set up the Opus advisor pattern, configure Claude Code model tiers, optimise their $20 plan quota by splitting models across roles, or match a subagent tree that assigns different models to different jobs, even if they never say "advisor" or "tiering". Not for diagnosing why usage already drained (use diagnose-usage), choosing an effort level before a task (use choose-effort), plan limits and prices (use product-self-knowledge), or upgrading Claude Code itself.
