frugal-fable

Use when running on Claude Fable (or any premium model) and the work is token-heavy — building features, multi-file changes, research, testing, debugging, migrations, or anything spanning many files/sources. Keeps Fable on the judgment (decompose, architect, synthesize, review) and delegates bounded, verifiable heavy-lifting to cheaper models (Haiku/Sonnet/Opus) — with a quality floor so construction work is never owned by a weak agent. Triggers on requests to "be efficient with Fable", "don't burn tokens", orchestrate subagents, or delegate work. Also fires on cross-CLI delegation: "delegate to Codex", "use Codex/GPT for this", "second opinion from Codex", or offloading work to a separate Codex/ChatGPT quota.
