fable-advisor now runs on Opus 5 as its orchestrator, aiming at long-horizon agentic work.
- The setup uses Claude Code’s ability to run the session and subagents on different models.
- The plugin follows an architect pattern: the session runs on Opus, handling requirements, decomposition, specs, and verification.
- Implementation tasks are routed to the right lane, and a Fable 5 review happens at the end before anything is marked done.
- The author recommends setting the model to Opus 5 in Claude Code and using Medium reasoning effort.
