TESTING AND RELIABILITY / Grafana Labs
k6
Writes a k6 script from a matching example, then validates it by running it rather than by reading it.
“Generate, validate, and review k6 test scripts — load, stress, spike, soak, smoke, breakpoint, functional, and protocol. Covers HTTP, WebSocket, gRPC, browser, all executors, thresholds, checks, custom metrics, the k6-testing library, k6 Cloud execution, and the xk6 extension ecosystem; uses the xk6-docs CLI (with grafana.com web fallback) for docs lookup and validates every script by running it. Use when writing, generating, validating, or debugging any k6 or load-test script (including plain-language asks like "load test this API" or "stress test my service"), choosing executors/scenarios, or setting thresholds. For end-to-end website performance suites use k6-perf-test-website; for documenting k6 itself use k6-docs.”
01 / THE REASONING
Why this made the selection.
- The workflow is read example, adapt, save, validate, review, and it says to skip a todo list that would only mirror those steps.
- It separates protocol load tests from the website performance suite, which is a different skill.
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/SKILL.md
- README.md
- LICENSE
Our findings
- Frontmatter licence is Apache-2.0 and the description lists HTTP, WebSocket, gRPC and browser.
- README recommends `npx skills add grafana/skills` for tools that follow the Agent Skills standard.
- The definition routes functional/browser requests to different examples and requires named exec functions for multiple scenarios.
- A bare async check predicate is called out as always truthy, so the check would pass silently.
- The ordered validation table prevents a full ramping or arrival-rate load profile for non-browser scripts by choosing k6 inspect; browser imports match the preceding run row.
Not established by this review
- The skill was not executed inside a host agent.
- No bundled script, if present, was run against a real project.
- 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.
03 / PUT IT TO WORK
Add a skill to your workflow.
DOCUMENTED COMMAND
npx skills add grafana/skills/skills/grafana-k6/k6 --skill k6Run in your terminal to choose your AI tools, project or global scope, and installation method. This short command follows the current upstream version; the review covers the revision shown above.
Optional: install the reviewed revision
Keeps the original source and installer version where recorded, while leaving your AI tools and installation scope for you to choose.
npx skills@1.7.1 add https://github.com/grafana/skills/tree/1ccacf29049fde66637fe01ab93a83a772da323b/skills/grafana-k6/k6 --skill k6- Choose your AI tools and project or global installation scope in Skills CLI. The review applies to the source revision shown on this page.
- Retain all supporting files; separately configure companion skills, runtimes and service credentials named in the definition.
- Review the resulting diff and use an isolated target before any migration, deployment, load test or warehouse operation.
Before you start
- The complete k6 skill directory, k6 and any required browser/extensions; permission to test the exact target and a Cloud account only for Cloud runs.
