DeepSeek Harness Plugin: dsh-grafana-query (Read-Only Grafana Query Tool)

`dsh-grafana-query` is an open-source plugin for DeepSeek Harness that provides agents with read-only access to Grafana. It executes PromQL queries and reads alert statuses through Grafana data source proxies, without requiring complex authentication logic. The plugin offers six tools—including health checks, listing, querying, and reading alert statuses—supports both instant and range queries, and enforces limits on data points, series, and response size to prevent performance issues. Installation requires Node.js 22+ and Grafana 9.0+, and requires configuring the Grafana URL and token, as well as granting the service account appropriate read-only permissions.
