Codex Subagent Designer

Choose one primary mode and read only its workflow. Add another mode only when the request explicitly requires both deliverables.

Mode	Use when	Workflow
delegation-design	Decide whether, how, and where to delegate bounded work and integrate results.	Delegation design
subagent-prompting	Draft an explorer, worker, validator, reviewer, or forward-test prompt.	Subagent prompting
catalog-asset-design	Create, improve, or score reusable skills and agent templates.	Catalog asset design
agent-template-review	Review Codex TOML, runtime posture, skill resolution, handoffs, or crew coverage.	Agent-template review

Do not load sibling workflows or shared catalog references prospectively. Obey the active session's delegation and mutation constraints; a design does not itself authorize spawning agents, editing files, or external actions.
