Agentic Subagent Routing

Resolve subagent dispatch contracts. Business skills decide what work needs a subagent; this skill decides which agent role, model, and reasoning effort to use.

Before dispatching a subagent, collect:

backend: codex
caller_skill: <stable-skill-name>
slot: <semantic-slot-name>
category: <review|implementation|research|testing|optional>
hard_fail: false
readonly: <true|false|optional>

Use routes.yaml as the centralized route registry. Lookup order is exact caller_skill + slot, then global_slots, then categories, then defaults.<backend>.

For Codex, map the resolved contract to spawn_agent:

• agent_role -> agent_type
• concrete model -> model
• concrete reasoning_effort -> reasoning_effort
• null model or reasoning means omit that field and inherit the parent value

Do not require third-party skills to provide subagents.yaml or parse CLI output. The CLI/library exists for implementation, wrapper injection, tests, doctor, and manual diagnostics.
