75-76: Header content added correctly.

The new top-level heading and descriptive paragraph align perfectly with the PR’s objectives and mirror the manual changes in doc/metrics_catalog.md. No concerns with the content or logic here.

The new heading and the link to the OpenMetrics spec satisfy the PR’s goal and are consistent with the generator update. Everything looks good here.

⚠️ Potential issue

Fix formatting to satisfy golines.

The string literal in the WriteString call is too long and triggers the golines lint error. You can collapse both calls into a single raw string literal, for example:

-sb.WriteString("# xmptd OpenMetrics catalog\n\n")
-sb.WriteString("This document catalogs the [OpenMetrics](https://prometheus.io/docs/specs/om/open_metrics_spec/) instrumentation for xmptd.\n\n")
+sb.WriteString(`# xmptd OpenMetrics catalog
+
+This document catalogs the [OpenMetrics](https://prometheus.io/docs/specs/om/open_metrics_spec/) instrumentation for xmptd.
+
+`)

Then run:

golines -w pkg/metrics/docs/generator.go
go fmt ./pkg/metrics/docs/generator.go

to resolve the formatting error.

🤖 Prompt for AI Agents
In pkg/metrics/docs/generator.go around lines 75 to 76, the two consecutive
WriteString calls use string literals that are too long and cause golines lint
errors. Combine these two strings into a single raw string literal to reduce
line length and improve readability. After updating the code, run 'golines -w
pkg/metrics/docs/generator.go' and 'go fmt ./pkg/metrics/docs/generator.go' to
automatically format the file and fix the linting issues.
