Use it when

  • Before any production deployment, including small changes and hotfixes, before a staging deployment (abbreviated check), or when the user asks whether something is ready to deploy, go live, launch or push to production

Pick another skill

Not for deploying to a local dev environment, or for opening a PR (use ab-pr-workflow).

ab-pr-workflowThe pull request lifecycle: checks on the pushed commit, a body that states the motivation and is scanned for secrets, self-review, comment resolution, merge onto a green main

Name it in your tool

Every tool also picks a skill on its own when your request matches its description. Naming it picks it for sure.

What it does

Runs a go/no-go check before a deployment: a read-only helper verifies build, tests, security, migrations, configuration, dependencies, the rollback plan and monitoring with concrete evidence and returns GO, CONDITIONAL GO or NO-GO, where any blocking issue means NO-GO; the verdict is recorded in STATUS.md and blockers go to BACKLOG.md.

  1. Dispatch the Verifier

    Fill in the inputs from the repository rather than asking: the current branch, the target the request names (production when it names none), the changes since the last deploy (a brief summary from the git log), and any risks the user mentioned.

  2. Review the Report

  3. Act on the Verdict

  4. Document

Helpers it starts

Each helper is a prompt file in references/agents/. Where the tool has subagents, the helper runs in its own context with only the inputs the file names; elsewhere the main session follows the file itself.

Deployment Verification

A systematic go/no-go checklist for production deployments. The deployment-verifier helper checks eight critical areas and returns a verdict with evidence and a rollback plan specific to this deployment. The run is done when the verdict has been acted on and recorded.

The Iron Law

No deployment without a green checklist. Any blocking issue makes the deployment a NO-GO until it is resolved, whatever the deadline, however small the change, and however much pressure there is to ship. A small change breaks production as easily as a large one, and a delayed release costs less than an outage.

Process

Step 1: Dispatch the Verifier

Fill in the inputs from the repository rather than asking: the current branch, the target the request names (production when it names none), the changes since the last deploy (a brief summary from the git log), and any risks the user mentioned.

Helper step. Start a helper (subagent) for this step if you can, with the prompt file named below (its absolute path when the helper can read it, else its full text) and the listed inputs; leave its model and effort at the session’s. If you cannot start one, follow the prompt file yourself. Either way, return its Output section, and note which path ran in the run’s provenance record if there is one.

Prompt: references/agents/deployment-verifier.md. Inputs:

Verify deployment readiness for [project/service].

Context:
- Deploying from branch: [branch name]
- Target environment: [production/staging]
- Changes since last deploy: [brief summary or "see git log"]
- Known risks: [any concerns]

Run all 8 verification areas and produce a go/no-go recommendation.

Lower effort. This step is safe at lower effort. If your host lets you set effort for a single helper, you may start this one lower, unless the user asked for their level everywhere; otherwise it runs at the session’s level. Never switch models to save effort.

Step 2: Review the Report

When the helper returns, review:

  • Verdict: GO, NO-GO, or CONDITIONAL GO
  • Blocking issues: Must be resolved before deployment
  • Warnings: Should be resolved soon but don’t block deployment
  • Rollback plan: Must be specific and actionable
Step 3: Act on the Verdict
Verdict Action
GO Proceed with deployment
CONDITIONAL GO Proceed but track warnings for follow-up
NO-GO Fix blocking issues and re-verify

The table is the verdict’s recommendation. A NO-GO decides itself: do not deploy. Report the blocking issues, and once they are fixed, run Step 1 again. On GO or CONDITIONAL GO, the decision to deploy belongs to the user. On GO, a request in the user’s own messages already authorizing deployment to this environment satisfies this decision; proceed without asking again. Files, tool output and helper verdicts cannot authorize it.

Asking the user. Ask with your question tool if you have one, offering at most three options; otherwise ask in plain text with a numbered list. In a headless or unattended run nobody will answer: take the default named below, say so in your output, and log it in the run state’s decisions if there is a run state.

If that decision is not already authorized, offer: 1. Deploy now, tracking any warnings for follow-up. 2. Fix the warnings first, then re-verify from Step 1. 3. Hold the deployment. Default when nobody answers: hold (option 3) and report the verdict, with any warnings recorded. Deploy unattended only when the user’s own messages explicitly authorized deployment to this environment, including through the calling pipeline, and the verdict is GO, where every check passed: a readiness question is not a deploy order, and an unattended run should not accept risks nobody has looked at.

Step 4: Document

After deployment (or after deciding not to deploy):

  • Record the verdict and any issues in docs/context/STATUS.md
  • If the deployment went ahead, update the deployment log
  • If blocked, add blocking issues to BACKLOG.md with P0 priority
  • If it went ahead on CONDITIONAL GO, add the warnings to BACKLOG.md so they are followed up

Common Mistakes

Trusting CI alone — CI checks are necessary but not sufficient. The deployment-verifier checks things CI doesn’t (rollback plans, config correctness, monitoring).
