Want to keep using Fable 5? Teach Opus and Sonnet to "behave" like it.
Short summary
After Fable 5 shuts down, maintain code quality with Opus and Sonnet by documenting explicit playbooks that map common failure patterns—symptom → wrong instinct → correct move. The author shows how to package these as reusable skills in subagent teams, shifting from implicit model judgment to explicit procedural discipline.
- •Document Fable 5's implicit behavior as explicit playbooks: symptom → wrong instinct → correct move
- •Ship pre-built subagent teams with coded skills using tools like ccteams
- •Cheaper models (Opus/Sonnet) produce quality output when given rigorous procedures instead of vague guidance
