Codifies the existing (but silently skippable) humanize step as a
checked skill after a real content batch published without it —
codex hand-rolled its own generation call instead of going through
content-agent/agent.py, which unconditionally runs both draft_rewrite()
and humanize(). This skill makes the requirement explicit, gives the
safe invocation path, and states how to verify the pass actually ran
rather than trusting a delegate's self-report.
