Open-Source fable-advisor: Fable 5.1 Architect Orchestrating GPT-6 and Opus
daniel_mac8 · x · 2026-09-23
fable-advisor is a free, open-source Claude Code plugin (1.1k stars) that exploits Claude Code's ability to run each subagent on a different model. It implements the architect pattern: your session — on whichever model you prefer — acts as a full-time architect owning requirements, decomposition, specs, and verification. Implementation tasks are routed to lanes: routine work goes to GPT-6 Luna (effort max by default) via the Codex CLI, one-off high-complexity tasks go to GPT-6 Sol, and a clean-context Fable 5.1 reviews the finished work before anything ships.
