i've been running claude code with Fable as the orchestrator and Codex + Grok as second opinions for a while, and ended up packaging the whole setup as two plugins. sharing in case it's useful to anyone: claude-code-fusion. Fable plans and delegates, Opus/Sonnet/Haiku do the actual work, and the Codex and Grok CLIs handle reviews and second opinions on their own subscriptions instead of your claude quota. day to day you mostly don't touch it, the routing rules make the session delegate on its own. the commands i actually use: /grok:review for a second pair of eyes on a diff, /fusion:panel when i can't decide between two approaches (Codex and Grok answer the same question blind, then get compared), and /grok:task to hand grok something big. setup: claude plugin marketplace add okisdev/claude-code-fusion claude plugin install grok@claude-code-fusion claude plugin install fusion@claude-code-fusion then /fusion:setup once, and you're done.
