Prepare Then Commit, So Side Effects Stay Together

An agent that calls several tools which each change something can leave the effect half applied when one call fails after another succeeded, and the run ends with a state no part of the plan intended. This skill covers a prepare then commit pattern: a first phase that checks preconditions and takes a claim without changing anything, a durable record of the decision to commit, a second phase that applies every change or none, and a recovery path that reads the record after a crash to decide whether to finish or reverse.

Commands

$ openclaw command add --name "pending commits" --trigger "/twophase" --source "AWS Production" --message "List runs with a decision recorded but no commit recorded, showing which tool calls had already been prepared for each one."

$ openclaw alert-rule add --name "Prepared But Not Committed" --group-by "run" --window "15m" --action "Alert when a run stays prepared without a commit past the expected window, because a crash between the two phases leaves side effects neither applied nor reversed"

$ openclaw auto-fix add --name "Resolve or Reverse" --condition "prepared_age > commit_window" --action "Read the durable decision record and either finish the commit for every prepared call or reverse the prepared ones, choosing one direction only" --approval "manual" --notify "#ops-alerts" --max-runs "10 per day" --cooldown "20m"

$ openclaw runbook add --name "Recover a Half Applied Effect" --trigger "/runbook two-phase" --tags "advanced,recovery" --steps "Read the decision record. List which calls were prepared. Check which were applied. Finish the remaining calls or reverse the applied ones, and record which direction was taken."

Prepare Then Commit, So Side Effects Stay Together

# Prepare the calls, then commit them together An agent that calls several tools which each change something has no natural grouping. One call fails after two succeeded and the run stops with a state that no part of the plan asked for: half the change is live, half is not, and nothing on the platfo
