What problem does it solve? Coordinating multi-agent coding work creates a trust gap: a worker agent's report is only a claim, and accepting it blindly risks shipping unverified or unreviewed code. This Skill gives the coordinator a disciplined delivery process that independently verifies worker output, arranges fresh-context review, and publishes a reviewable PR while leaving the merge decision to the user. ## Core Features & Use Cases - Independent Verification: Re-run the project's declared verification contract against the exact candidate SHA in a detached checkout via sumctl verify --execute, keeping worker claims, reviewer findings, and coordinator runs as separate evidence records. - Nine-Gate Delivery Pipeline: Drive Intent, Rebase, Review, Test, Document, Lint, Push, PR, and CI gates with sumctl pipeline run, where every row is derived from saved task records rather than set by hand. - Safe PR Publication: Push fast-forward only, adopt existing PRs instead of duplicating them, publish before/after evidence and pipeline tables into marked PR blocks, and reconcile PR identity through gh after every push. - Use Case: A worker agent reports a bug fix complete. You run the delivery flow to re-verify the candidate yourself, launch a separate reviewer, open the PR with evidence attached, and present the URL to the user, who alone decides whether to merge. ## Quick Start Ask the coordinator to verify the worker's latest candidate for a task, arrange an independent review, and open a pull request without merging it.
