TESTING AND RELIABILITY / Grafana Labs
k6 test maintenance
Treats a k6 edit as behaviour-aware change control, with a validation loop on every edit.
“Maintain and improve existing k6 test scripts. Covers threshold tightening based on trend data, version migration between k6 releases, auto-fixing tests when the underlying service changes, refactoring for cleanliness, and auditing scripts against current best practices from docs. Use when the user asks to fix a failing k6 test, tighten thresholds, migrate a script to a new k6 version, refactor a test, update a script after a service change, or improve a script with best practices. Trigger on phrases like "fix my k6 test", "tighten my thresholds", "migrate to k6 v2", "update my test script", "refactor this k6 test", "my test is failing after a deploy", "apply best practices to my script", "modernize my k6 test", or "the service changed and my test broke". Also trigger when another skill (k6-trend-analysis or k6-cloud-investigate-test) hands off with a recommendation to edit a script.”
01 / THE REASONING
Why this made the selection.
- The core-principle heading is behaviour-aware change control.
- A validation loop is required on every edit, not only at the end.
02 / THE REVIEW RECORD
What we actually inspected.
Source review has boundaries.
A clear record is more useful than a “safe” badge.
Material inspected
- skills/grafana-k6/k6-test-maintenance/SKILL.md
- README.md
- LICENSE
- skills/grafana-k6/k6-test-maintenance/references/verification.md
Our findings
- Headings include Validation loop (every edit).
- The description covers version migration and threshold tightening.
- The definition separates configuration-only historical prediction from runtime-logic verification and documents GET-backup-edit-validate-PUT-hash checks.
- The definition permits k6 inspect for parse-only validation without a browser, or mcp-k6 validate_script; browser runtime behavior still needs a browser-backed smoke or cloud run.
- The migration guidance warns that k6 x docs reflects the installed runtime and may lag the API of the migration target.
Not established by this review
- The skill was not executed inside a host agent.
- Not executed: it was not installed or run.
The review applies to the material and revision named here. A newer upstream release can change its behavior.
