description	Request a capability-safe executor handoff from a durable Prewalk Stop checkpoint.

$prewalk:pw-go - hand off to the executor

Inspect the live spawn_agent schema first. Pass the field names it actually exposes to the state transition helper, then follow its output exactly:

python3 hooks/_pw.py go "${CODEX_THREAD_ID:-${CODEX_SESSION_ID:-}}" \
  --schema-fields=task_name,message,fork_turns,model,reasoning_effort

Omit any field name that is absent from the live schema. Do not claim support from a preset or documentation; only the current tool schema is proof.

If no active checkpoint exists, report that in one line and stop.

Native spawn path

1. If the helper reports an unsupported route, do not spawn. The durable checkpoint remains ready for diagnosis or recovery.
2. When routing is supported, call spawn_agent exactly once with the helper's generated task_name, the exact text between PREWALK_MESSAGE_BEGIN and PREWALK_MESSAGE_END as message, fork_turns: "none", and the configured executor model. Include reasoning_effort only when the helper prints it. Do not use a named plugin agent and do not alter the message.
3. Wait for the bound executor. Codex hooks bind the agent ID returned by this exact tool call and consume only that agent's SubagentStop marker.

Do not run manual confirm/complete commands. Spawn denial, failure, interruption, missing markers, and incomplete markers remain durable for pw-retry recovery.
