[install] Optional — add this to ~/.codex/AGENTS.md so Codex always knows the tool:

  ## SkillOpt-Sleep
  An offline self-improvement cycle is available. To run it:
  \`bash "$REPO_ROOT/plugins/run-sleep.sh" status\`. Use \`/skillopt-sleep\` for the guided flow.

Done. Try:  /skillopt-sleep status
