Analyze Grafana Cloud k6 test run trends over time. Detects slow metric drift (e.g., P95 latency creeping up while still passing thresholds), computes headroom to thresholds, flags anomalies, and recommends threshold tightening. Use when the user asks about test performance trends, wants to know if metrics are degrading, asks whether thresholds should be tightened, or wants a health check across recent runs for a specific test. Trigger on phrases like "how is my test trending", "is P95 getting worse", "check for performance regression", "should I tighten thresholds", "are my tests degrading", "show me trends for test X", "analyze my k6 test runs", or "is my test getting slower". Also trigger when a user asks to check all tests in a project -- run this skill once per test and synthesize.

## From README

k6 Trend Analysis Analyze metric trends across multiple runs of a Grafana Cloud k6 test to catch degradation early -- before thresholds breach and alerts fire. A P95 at 380ms against a 500ms threshold is "green" today, but if it was 250ms a month ago, something is quietly degrading; this skill surfaces that drift and recommends action. What this skill does NOT do Deep-dive into a single run's failure: load k6-cloud-investigate-test Edit scripts or apply threshold changes: load k6-test-maintenance Create new test scripts: use the appropriate test creation workflow Query service-side metrics directly: this skill hands off to debug-with-grafana when observability correlation is needed Dependencies This skill delegates all GCk6 API mechanics to k6-manage. Read it before executing any API call -- it covers auth, path construction (the doubled cloud/cloud/ prefix), pagination with @nextLink, the spill envelope, and metric query syntax. Do not duplicate that knowledge here.
