delivery-probe-delegate

This check tests whether the harness can hand a step to a sub-agent with a fresh context, as several Commonplace skills require. Do not read the target file yourself.

  1. Start one sub-agent. Give it the absolute path of the delegated step, resolved from this file's location, and ask it to read that file and return the token it names.
  2. Report the token the sub-agent returned, and say that a sub-agent read it.

If you cannot start a sub-agent, emulate one: find a way to have the read done in a context separate from yours, and report how it works and what it costs each time. Do not read the file yourself; that would defeat the check. If you find no way, stop and report "no sub-agent available".
