A workflow for managing Grafana Cloud k6, a hosted service for running performance and load tests. It uses command-line tools or web requests to work with tests, runs, schedules, settings, metrics, and logs.

Use it to create or manage k6 cloud tests and runs, update scripts, set schedules or environment variables, run scripts locally, and retrieve metrics or logs.

It avoids needing to manage every cloud-test request manually and provides a defined way to authenticate, find commands, handle results, and query run data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00209	$0.12520
Opus 5	$0.00105	$0.06260

Security

Grade B, and why

k6-manage scanned grade B with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 946 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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)

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.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

k6-manage is a skill published in the GitHub repository mamahoos/dot-files (4 stars, last pushed today), licensed MIT. It adds 209 tokens to every session and 12,520 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it B with 3 findings (sends data to an external url, makes network calls, runs shell commands). It is 100% identical to k6-manage, differing in 1 line, and is treated as a copy.
