Fable orchestrator

Claude Fable 5.1 supplies orchestration decisions only. Codex remains the runtime that spawns workers, owns files, runs tools, verifies the result, and reports to the user.

Invocation

Treat everything after $fable as the objective. Fable 5.1 always owns orchestration. Implementation workers are restricted to GPT-5.6 Luna and DeepSeek V4 Flash:

• $fable build the feature
• $fable debug this; implementer: gpt-5.6-luna
