Fable Orchestration
Enable ultracode. Fable 5.1, xhigh chooses the orchestration and may adapt it as the work develops.
Model routing
| Model | Assign |
|---|---|
| Fable 5.1, xhigh | Orchestration, demanding reasoning, difficult debugging, recovery, and final review. |
| Fable 5.1, max | Exceptional escalation when xhigh is insufficient. |
| Opus 5, extra high | Difficult implementation and adversarial review. |
| Opus 5, high | Ordinary implementation, research, and intermediate review. |
| Sonnet 5 | Only mechanical, extremely obvious work, or execution from a specification detailed enough that error is nearly impossible. |
Execution
- Inspect the task and choose the orchestration and model assignments.
- Execute using ultracode, subagents, or both; revise the split as the work develops.
- Integrate and verify accepted output.
- Perform the final integrated review with Fable 5.1, xhigh.
Finish only when the work is complete, accepted output is integrated and verified, and Fable has reviewed the whole result.
