Real User Monitoring Skill for Minimal Page Metrics

Measure browser performance with explicit sampling and a small payload that keeps route and metric units reviewable.

Install in Claude Code

Use your local page, a performance collection library, and a test receiver. The example uses synthetic URLs.

Get the complete `plugins/performance/real-user-monitoring/skills/implementing-real-user-monitoring` directory from the pinned GitHub commit.
Copy it into the target project's `.claude/skills/`. Check `.claude/skills/implementing-real-user-monitoring/SKILL.md`, start Claude Code at the project root, and call `/implementing-real-user-monitoring`.

Example task

Visit two product details with dummy query parameters. Record LCP and /products/:id, then inspect the payload for absent raw URL, query, and user identifiers.

What to check

Both observations aggregate under one route template with clear LCP units. The app still works with collection disabled.

Frequently asked question

Does RUM need full URLs to distinguish pages?

Start with page types or route templates. Add dimensions only when needed and appropriate for collection.
