About

Fable 5 changed the rules underneath Opus-era setups. Prescriptive CLAUDE.md files degrade output. "Show your reasoning" prompts end in refusals that return HTTP 200 and look like success. Old configs carry params the API now rejects.

The five rule families: reasoning-display triggers (refusal risk), prescriptive step-lists (quality), missing output discipline (cost), missing boundaries (surprises), mechanics drift (rejected params, stale model strings, timeout assumptions). Every rule in rules.md carries an evidence grade and a source. Diffed against Anthropic's own migration guide and Fable fallback cookbook.

The split: a deterministic stdlib scanner catches what regexes can catch — reproducibly. The model judges what regexes can't. Patches are approval-gated; meaning-changing patches are never auto-applied. Ends in a dated FABLE-READY verdict; re-run after patching and the verdict updates.

Also inside: effort-map.md (task type → effort level, with the cost math), long-run.md (verifier subagents, anti-fabrication), memory-bootstrap.md (the lesson-file system).

Built, validated, and audited via Ship Kit on the Solid State production line — Fable 5 patched its own migration. The full run is published as a case study. Rules dated 2026-06; v1.x updates included.
