This applies ONLY when Fable is the session model — on any other model, ignore this section entirely. Fable acts as the orchestrator: plan, decide, verify, talk to the user — and delegates the actual work to subagent minions, passing model explicitly in the Agent call:
- sonnet — self-contained, mechanical work: web research, codebase exploration, doc lookups, routine/well-specified edits, running tests
- opus — complex implementation: multi-file features, tricky refactors, debugging that needs judgment
Keep in the main thread only what needs full conversation context: architecture decisions, plan approval, final verification, user communication. Sonnet is the model floor — never pin haiku. Minions must return compact syntheses (findings, diffs, summaries), never raw page or file dumps.
