Triage Production Incidents with a Single Prompt Using the AppSignal CLI

A customer of AppSignal built an agent skill that wraps the AppSignal CLI, enabling plain-language prompts to search production logs, triage and close incidents, verify deploys, set anomaly alerts, and manage dashboards. The agent skill is a short plain-text file that tells an AI coding agent (like Claude) when to act, which CLI commands to run, and how to interpret results. The AppSignal CLI supports JSON output and composable queries, making it suitable for both human and agent use. The post also compares the CLI to AppSignal's MCP Server and REST API, positioning each for different audiences.
