Fable Orchestrator

Fable Orchestrator is a local routing skill for developers who want separate planning and implementation roles in Codex. Claude Fable makes planning decisions and reviews results, while Codex retains control of the workspace and tools.

• Planning and review Fable breaks an objective into bounded tasks and adjudicates results without writing code or taking ownership of project files.
• Implementation routing GPT-5.6 Luna handles ordinary coding work, while DeepSeek V4 Flash handles repeated iteration and high-throughput tasks through OpenCode Go agents.
• Parallel workers Codex validates the proposed task graph, starts independent workers in parallel when useful, collects their evidence and verifies the result.
• Restricted model routes Implementation tasks must use one of the two permitted models; the workflow reports a blocker if neither route is callable.

The skill requires an existing Codex Router setup that supplies the OpenCode Go agents. Its planning helper invokes Claude Code's local Fable alias without keeping a persistent session. Planning packets contain decisions and workspace facts and must exclude credentials.

Fable Orchestrator is open source under the MIT license. It runs as a skill in your local Codex environment and depends on the connected clients for model access. It doesn't include a model runtime, proxy or credential store.
