Claude Multi-Agent

Requires the claude CLI installed, authenticated, and on PATH, plus git and jq. Invoke it from a shell-capable agent such as Codex, another Claude Code instance, or CI.

Turn Claude Code into an autonomous engineering team that another agent can delegate to. The calling agent (Codex, another orchestrator, CI) plays product owner / user. Claude Code plays the engineering team: an Opus 4.8 orchestrator that thinks, plans, and delegates concrete subtasks to Sonnet 5 subagents that do the heavy lifting.

Never use Fable in this setup. Fable is a lightweight/fast-path model not suited for either the orchestrator seat (needs Opus's reasoning) or the worker seat (needs Sonnet's coding reliability).

The core mechanism

Four levers control who does what and how reliably, and all four ship pre-wired in this skill:
