Multi-model orchestration for Claude Code. Your chosen Claude session model is the control plane and final judge; Claude workers cover native tool, privacy, and read only reasoning needs; peer engine CLIs provide external implementation, research, and review lanes billed to their own subscriptions. Today those peers are Codex and Grok through first party companion plugins hosted in this marketplace; the companion contract is engine agnostic so more lanes can fit the same shape. The Codex plugin invokes the official CLI directly and has no dependency on `codex-plugin-cc`. The orchestrator and Claude worker tiers still bill to your Claude plan; delegation moves eligible execution off it. The plugin audits but never sets the session model.
| Layer | Who | Job |
|---|---|---|
| Orchestrator | the user's chosen main session model; best[1m] is recommended but never set by the plugin |
sole control plane: resolve ambiguity, decompose, integrate, verify, record semantic acceptance, make the final judgment, and communicate with the user; it does not execute work packages; it authors judgment dense cores (naming, API shape, UX copy, policy text) itself under the authorship rule and dispatches their mechanical spread |
| Claude workers | fusion:deep-reasoner (Fable), fusion:claude-worker (Sonnet), fusion:trivial-worker (Haiku) |
native specialists rather than external diversity: read only high stakes advice, resolved work whose load bearing capability is the Claude Code tool surface or privacy boundary, structurally stranded packages carrying claude-fallback: , and exact tiny fallback packages when no eligible peer lane fits |
| Peer engines | Companion plugins implementing the shared contract. Current instances are the hosted Codex and Grok plugins in this marketplace | Codex is the primary implementation lane and default deep external reviewer. Grok is a complementary specialist and burst lane with four protected roles: burst, `inde |
