## What it does

The skill equips an agent with instructions for Grafana Cloud k6 (GCk6). It manages test runs, scripts, project limits, and schedules. By default, it prioritizes `gcx k6` subcommands and falls back to `gcx api` for lower-level routes.

When `gcx` is absent, the skill switches to direct `curl` calls. It contacts `https://api.k6.io` and `https://cloudlogs.k6.io`. In curl mode, every call requires a manual bearer token and stack ID, or the API rejects the request. Specific queries for Loki logs and Tempo traces also require an explicit `X-K6TestRun-Id` header.

## Requirements
- Works with: Grafana

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill k6-manage -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/k6-manage/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/k6-manage/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill k6-manage -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/k6-manage/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill k6-manage -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/k6-manage/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install grafana/skills k6-manage
```

2. **Manually: put the files in place**
- File: `.github/skills/k6-manage/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill k6-manage -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/grafana/skills --path skills/grafana-k6/k6-manage
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/k6-manage/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill k6-manage -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/grafana/skills/tree/HEAD/skills/grafana-k6/k6-manage/SKILL.md

## When to use it
- run k6 scripts locally or trigger cloud load tests
- inspect execution logs and failure reasons in Loki
- query performance metrics and Tempo traces for specific test runs
- update k6 scripts, project limits, and schedules

## Example prompts
- Show me logs for run 12345
- Why did my k6 test fail?
- Bump the VUh limit on project staging-load

name: k6-manage
description: Interact with Grafana Cloud k6 (GCk6) — manage load tests, test runs, scripts, projects, schedules, env vars, fetch metrics or logs, and run scripts locally — using the `gcx` CLI (or direct curl when gcx is unavailable). Use this skill whenever the user mentions a k6 cloud test or run, asks to list/edit/create/start/abort k6 load tests, wants to fetch logs or metrics for a test run, manage k6 project limits or schedules, run a k6 script locally or via `k6 cloud run`, or needs to call any `/cloud/v6/`, `/cloud/v5/`, or k6-app Loki endpoint against a Grafana Cloud stack. Trigger even when the user doesn't explicitly say "gcx" or "API" — phrases like "why did my k6 test fail", "show me logs for run X", "bump VUh limit on project Y", or "update my k6 script" all qualify.

# Grafana Cloud k6 — interaction reference

The default path is the `gcx` CLI. When gcx isn't installed, every
endpoint here is still reachable via direct curl against k6's public
hosts — see §1.2 for the auth-header and host-translation rules. Two
principles shape the rest:

- **gcx owns Grafana-side auth (when present).** It injects the right
  headers on every call, so you should not set auth headers yourself.
  The only header you ever set by hand is `X-K6TestRun-Id`, on Loki
  log queries (§4), browser screenshot/file fetches (§6), and Tempo
  trace queries (§7) — anything else gets overwritten or causes
  conflicts. In curl mode the auth headers are manual; see §1.2.
- **Reach for `gcx k6 ...` subcommands first.** They wrap the common
  paths with friendlier ergonomics and handle pagination. Discover
  what's available with `gcx help-tree k6` (and drill in further with
  `gcx help-tree k6 <subcommand>`); fall back to `gcx api` only when
  no subcommand exists for what you need.

## 1. Authentication

### 1.1 With gcx (default)

```bash
gcx login --context <ctx>                # one-time OAuth, browser flow
gcx --context <ctx> config check         # expect "✔ Connectivity: online"
```

Once a context is logged in, every `gcx api ...` and `gcx k6 ...` call
inherits its auth state. If a call returns *"Invalid or expired token —
run gcx login to refresh"*, the OAuth session has lapsed — re-run
`gcx login --context <ctx>`.

### 1.2 Without gcx — direct curl

Check `command -v gcx` first. If it's missing, every endpoint in this
skill is still reachable directly against k6's public hosts — three
things change versus the gcx examples elsewhere:

- **Auth headers are manual.** Set both on every call:
  - `Authorization: Bearer <k6_token>`
  - `X-Stack-ID: <int>`
- **Hosts replace the plugin proxy.**
  - REST (`/cloud/v6/...`, `/cloud/v5/...`, `/cloud-resources/v1/...`,
    `/insights/...`) → `https://api.k6.io`
  - Logs (Loki) and traces (Tempo) → `https://cloudlogs.k6.io`
- **No `/api/plugins/k6-app/resources/{cloud,logs,insights}` prefix.**
  Drop it; everything after that prefix in the gcx examples is the
  real k6 path. The doubled `cloud/cloud/` quirk from §2 collapses to
  a single `/cloud/` — the first one was just the proxy route.

#### Obtaining the credentials

Don't guess these — prompt the user once per session for:

1. **k6 API token** — long-lived bearer; the same value
   `gcx k6 auth token` would print when gcx is configured.
2. **Stack** — either the integer **stack ID** (used directly in
