cast-subagents

Use when suggesting exactly one Codex subagent lineup before work begins for multi-lane tasks: branch/PR review across bugs, security, tests, maintainability, docs, or regression risk; codepath tracing plus docs/API verification; option research with tradeoff synthesis; auth/codebase mapping before risk assessment or planning. Advisory only; no auto-spawn; approval required. Do not use for delegated subagent handoffs, trivial single-file fixes, wording-only edits, one fact lookup, unclear requests, or explicit opt-out.
