Cloud Monitoring Chart Generation Skill (cloud-monitoring-chart-generation)

Transforms PromQL or ListTimeSeries JSON request payloads and metric metadata into valid Server-Driven UI (SDUI) google.monitoring.dashboard.v1.Widget Protocol Buffer textprotos. These generated textprotos are designed to be ingested by the Cloud Monitoring Dashboards API, gcloud CLI, or declarative dashboard provisioning pipelines.

[!IMPORTANT] Preferred API & Mutually Exclusive Queries:

• API Preference: Always prefer generating ListTimeSeries (time_series_filter) configurations for widgets over PromQL, unless the user explicitly requested PromQL or the metric math strictly requires it.
• Mutually Exclusive: A widget dataset time_series_query must contain EITHER a time_series_filter OR a prometheus_query. You must never populate both fields in the same dataset simultaneously.
• Strict Passthrough: You MUST copy the provided PromQL query or ListTimeSeries JSON exact filter string character-for-character. DO NOT invent, rewrite, or modify the queries under any circumstances.
