Summary of changes

Summary of changes

• Updated the thv_reg_srv_servers_total and thv_reg_srv_skills_total rows in
  the metrics reference table in
  docs/toolhive/guides-registry/telemetry-metrics.mdx to reflect the
  registry -> source attribute rename and the new "distinct in each source"
  semantics (verified against
  internal/telemetry/metrics.go at the v1.4.3 tag).
• Added a :::note admonition in the same file calling out the breaking label
  rename for operators with existing Grafana queries, Prometheus alerts, or
  dashboards, and clarifying that thv_reg_srv_sync_duration_seconds still
  uses the registry label.

How this PR was built

Two Claude Opus sessions run per release: a generation pass
(upstream-release-docs skill, 6 phases) followed by a fresh-
context editorial pass (docs-review). Prettier/ESLint
auto-fixes are applied after.

Auto-synced paths — do not hand-edit these in review:

• docs/toolhive/reference/cli/
• docs/toolhive/reference/crds/
• static/api-specs/

If a "Gaps needing human context" section is present above,
each entry includes a paste-ready Helper prompt for local
Claude a reviewer can use to resolve the gap.

Upstream release docs: toolhive-registry-server v1.4.2 → v1.4.3

• Phase 1: Discovery — fetched release notes, identified stacklok/toolhive-registry-server#784 (metrics fix) and #785 (release PR)
• Phase 2: Deep-dive — verified label/description changes in internal/telemetry/metrics.go at the v1.4.3 tag
• Phase 3: Docs audit — only docs/toolhive/guides-registry/telemetry-metrics.mdx affected
• Phase 4: Implementation — updated table rows + added a note about the rename
• Phase 5: Validation — Prettier and ESLint clean; local build fails on the unrelated mcp-metadata-plugin network fetch (sandbox-only — CI handles this)
• Phase 6: Wrote SUMMARY.md and committed

Summary of changes

• Updated the thv_reg_srv_servers_total and thv_reg_srv_skills_total rows in the metrics reference table at docs/toolhive/guides-registry/telemetry-metrics.mdx:87-88 to use the renamed source attribute and the new "distinct in each source" semantics (verified at internal/telemetry/metrics.go lines 48-80 in stacklok/toolhive-registry-server@v1.4.3).
• Added a :::note admonition flagging the breaking label rename for operators with existing Grafana queries, Prometheus alerts, or dashboards, and clarifying that thv_reg_srv_sync_duration_seconds still uses the registry label (verified at internal/telemetry/metrics.go:143).

Editorial review: telemetry-metrics.mdx (v1.4.3 changes)

• Read the modified file and review the diff
• Verified upstream PR Update toolhive to v0.23.1 (manual dispatch) #784 — registry → source rename, observable gauge for staleness fix, counts registry_entry (not entry_version)
• Ran /docs-review over the change
• Applied actionable fixes
• Ran Prettier and ESLint (clean)
• Committed and pushed

Findings

Primary issues: none blocking.

Secondary issues (applied in 38fb46e):

1. Description phrasing (lines 87-88) — "Number of distinct servers in each source" was awkward. The word "distinct" did real work upstream (counts registry_entry, not entry_version), but the docs don't establish a versions concept, so it landed as filler. Switched to "Number of servers per source" / "Number of skills per source" to match the existing row patterns.
2. Admonition severity (line 91) — operators with existing Prometheus alerts or Grafana dashboards will see them break on upgrade. Promoted :::note to :::warning to flag the breaking change appropriately.
3. Terminology drift (lines 93-94) — the note used "attribute" once, then "label" twice. The table header is "Labels" and that's what readers see in PromQL/dashboards. Aligned on "label" throughout the note.
