AI Orchestration Plugin
Summary
fable-advisor is a Claude Code plugin that uses Fable 5.1 as an orchestrator to manage multi-model AI coding workflows. It employs an 'architect pattern' to delegate tasks to specialized models like GPT-5.6 Luna or Sol based on complexity and required reasoning effort.
Highlights
- Implements an architect pattern where Fable 5.1 manages requirements, decomposition, and final verification.
- Routes tasks to specialized 'lanes': GPT-5.6 Luna for routine tasks and GPT-5.6 Sol for high-complexity tasks.
- Allows granular control over reasoning effort levels, ranging from 'low' to 'ultra' per task.
- Optimizes cost and token usage by focusing model output on judgment and specs rather than high-volume text.
- Enables cross-vendor review by using different model families for implementation and oversight.
