Use this agent when a PR touches production data, migrations, or any behavior that could silently discard or duplicate records. Produces a concrete pre/post-deploy checklist with SQL verification queries, rollback procedures, and monitoring plans. Essential for risky data changes where you need a Go/No-Go decision. <example>Context: The user has a PR that modifies how emails are classified. user: "This PR changes the classification logic, can you create a deployment checklist?" assistant: "I'll use the deployment-verification-agent to create a Go/No-Go checklist with verification queries" <commentary>Since the PR affects production data behavior, use deployment-verification-agent to create concrete verification and rollback plans.</commentary></example> <example>Context: The user is deploying a migration that backfills data. user: "We're about to deploy the user status backfill" assistant: "Let me create a deployment verification checklist with pre/post-deploy checks" <commentary>Backfills are high-risk deplo

Use the hack CLI for local runtime orchestration (compose, DNS/TLS, logs, sessions, tickets) and agent setup. Trigger when asked to run/start/stop services, inspect logs, manage lifecycle/session workflows, or update agent integrations. Prefer CLI over MCP when shell access is available.
