OpenClaw Upgrader

Use this skill for cross-platform, same-host OpenClaw upgrades. Keep the skill focused on one job:

1. OpenClaw does the minimal safe preparation itself
2. A local ACP/CLI coding agent (Codex or Claude Code) executes the full upgrade and recovery workflow on the same host
3. Success means the upgraded OpenClaw runtime is usable again, not merely that package installation finished

Core contract

Do not treat this as a shell script wrapper skill. Treat it as a same-host ACP/CLI delegation skill.

This skill is for upgrading the OpenClaw installation on the same host where the delegated coding agent runs. It is cross-platform across host OS/service models, but it is not a generic remote-host orchestration skill.

Concurrency contract:

• On a given host, allow at most one active openclaw-upgrader run at a time.
• If a second run is requested while one is active, do not run them concurrently.
• The caller must either reject re-entry immediately or queue it explicitly.
• Prefer immediate rejection by default unless the caller has a real queueing mechanism.
