Pair a Sonnet main model with a Fable 5 advisor
guidance
The advisor tool lets Claude consult a second, typically stronger model at key moments during a task — before committing to an approach, when stuck on a recurring error, or before declaring a task complete. "Sonnet main + Fable advisor: Fable 5 guidance at decision points without running Fable 5 throughout. Requires v2.1.170 or later and Fable 5 access." This is the pairing this repo dogfoods: this session runs on Claude Sonnet 5 as the main model, and the actual subagentcode.com and subagentprompts.com builds each used a real Agent-tool dispatch to Fable 5 — once as the primary builder, once as an advisor reviewing the draft — rather than running Fable 5 for the entire session.
