# SKILL: Claude FABLE 5 spanking Claude OPUS 4.8

A Claude Code skill that makes the expensive orchestrator model read and judge while cheaper subagents do all the writing.

The name is the whole idea. Fable 5 is the main loop, the frontier model billed per token to metered credits. It never drafts a line. It decomposes the work, writes the spec, spawns Claude Opus 4.8 subagents to do the labor, then grades what comes back. The orchestrator cracks the whip; Opus does the digging, drafting, and sweeping. Hence the title.

## The problem

There is a billing asymmetry between the two models in play. The main-loop frontier model bills its output tokens to metered usage credits. Subagent models bill to a flat subscription plan allowance. Drafting is output-heavy: writing code, docs, and tests burns exactly the tokens that cost the most. Verification is read-heavy: it consumes input, not expensive output. So the expensive model should read and judge, and never write.

## The model policy

| model | role | billing |
|---|---|---|
| main loop (e.g. Fable 5) | decompose, spec, review, validate, decide, talk to the user | metered credits, minimize output |
| opus-4.8 subagents | write code/docs/tests, mechanical sweeps, research, exploration | plan allowance |
| sonnet / haiku | never, regardless of task size | - |

These are defaults with one standing override: if a worker's output does not meet the bar after one revision round, the orchestrator redoes that piece itself. Judge the output, not the price tag. Escalating costs less than shipping mediocre work.
