What is it?

Fable Advisor is a Claude Code plugin built around an architect pattern. The session model owns requirements, task decomposition, specs and verification. Implementation tasks are routed to one of two lanes: GPT-6 Luna for well-specified routine work, or GPT-6 Sol for harder tasks such as subtle concurrency, debugging and security-sensitive changes. Both lanes run through the OpenAI Codex CLI.

A read-only reviewer agent pinned to Fable 5.1 checks the accumulated changes in a clean context before the architect reports a deliverable as done. It is also consulted at architecture decisions, migrations and API design points. The reviewer never writes code.

The plugin includes a routing skill, a six-part spec format, and a setup command that saves per-lane model and effort choices. A lighter option is a single agent file that adds advisor consults to any Claude Code session.

Key features

  • 01Routes implementation tasks to GPT-6 Luna or GPT-6 Sol via the Codex CLI.
  • 02Uses a Fable 5.1 read-only reviewer for architecture consults and a final review.
  • 03Sets a default reasoning effort per lane, overridable in each spec.
  • 04Labels each delegation with the model and effort running it.
  • 05Provides a /fable-advisor:setup command to choose lane models.

Use cases

  • Delegating routine feature work to a cheaper cross-vendor implementer while keeping architecture in a stronger session model.
  • Getting an independent review of a finished change before merging.
  • Adding a Claude-based second opinion to an existing Claude Code workflow without the full orchestration layer.

Quick start

  1. 1

    Add the plugin marketplace

    claude plugin marketplace add DannyMac180/fable-advisor
  2. 2

    Install the plugin

    claude plugin install fable-advisor@fable-advisor
  3. 3

    Install the Codex CLI for the implementer lanes (requires authentication afterwards)

    npm i -g @openai/codex
  4. 4

    Run setup once to choose lane models

    /fable-advisor:setup

Things to know

  • Requires Claude Code 2.1.170 or later and a subscription that includes Fable 5.1 for the default reviewer.
  • Both implementation lanes need the OpenAI Codex CLI installed and authenticated, plus access to GPT-6 models.
  • The architect and reviewer rely on Claude models, so the full pattern is tied to Claude Code and does not run on claude.ai.
  • If a pinned Claude model is unavailable on your account, Claude Code silently falls back to the session model.
