Runbook Skill · ariestar bundle Use before coding, debugging, build, test, deployment, infrastructure, database, repository maintenance, or agent handoff tasks to run `runbook scan`, understand the current project and machine tool environment, choose the right CLI tools, avoid package-manager/build-tool confusion, and respect risk guardrails before mutating files or remote systems. Also use when the user asks what tools are available, which tool should be used, or how an agent should prepare before starting work.
