gcx: Skill for Claude Code

.claude/skills/integrate-with-gcx/SKILL.md

integrate-with-gcx is a skill for Claude Code from grafana/gcx. It costs 219 tokens per session (3,544 once invoked), scanned A, original, Apache-2.0.

A contributor workflow for adding or extending commands in gcx, a command-line tool for managing Grafana resources. It helps decide whether the capability belongs to a provider, datasource, resource adapter, cloud command, or reusable skill.

In plain words
What is it for?
Use it to plan and implement gcx capabilities, choose command locations and names, define their agent-facing help, and verify the result against the repository.
Why use it?
It prevents new commands from being placed in the wrong part of the codebase or given an unclear interface for other coding agents. It also treats command names and help metadata as long-term compatibility decisions.

About the project

gcx is a command-line tool that lets people and AI coding agents manage and inspect Grafana Cloud, Enterprise, and open-source instances. It provides access to dashboards, alerts, SLOs, metrics, logs, and traces, with workflows for alert investigation, dashboard management, GitOps, and observability setup. Its catalogue entries provide agent instructions and extensions for using gcx.

SkillSpector: 3 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high System Prompt Leakage · line 187
    Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.
    Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
  • medium Excessive Agency · line 22
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
  • medium Agent Snooping · line 232
    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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.

Security

Grade A, and why

integrate-with-gcx scanned grade A with 0 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 280 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Integrate a Capability with gcx

Work autonomously. Inspect the repo, decide, show the decision, keep going. This skill has no approval gates. Ask only when repository evidence genuinely cannot settle something (Asking).

The premise everything follows from: the commands you add are tools other agents route on. Use/Short/Long/Example, flag help, token cost and hints are surfaced verbatim through gcx commands and gcx help-tree — that metadata is an operational contract, not decoration. Names are frozen within a major version, so the path you pick is the path forever.

Mode You are here when
Place where this belongs is undecided
Build placement is known — you decided it, the user stated it, or a sibling skill sent you
Review there is already a branch or PR to get review-ready

Start with mise run build, then bin/gcx commands >/dev/null && echo ok. Read AGENTS.md — the entry point for the governing docs; paths cited below are cited directly, including docs/plans/ and docs/research/, which its map does not list. Use bin/gcx for your own shell checks (exercise the binary you just built, not a stale installed one); everything user-facing you author — Example: fields, help text, docs — says gcx.

Mode: Place

Detail: references/placement-and-readiness.md

Inventory the tree first — a new leaf competes for every agent's attention:

bin/gcx help-tree
bin/gcx commands --flat -o json
bin/gcx resources list-types
bin/gcx providers list

Settle four things and show them as a short placement section (bullets, not a document):

  • Necessity — reuse / extend / consolidate with a sibling / new leaf / not gcx. For a new leaf, name the nearest existing sibling and the one sentence an agent would use to choose between them. If a person who knows the tree can't say which command applies, an agent can't either.
  • Path — from docs/design/command-naming.md plus precedent in the real tree and docs/plans/list-subject-verdicts.md.
  • Backend + wiring — what serves the data, verified by a probe rather than assumed, and which wiring carries it. A probe that is unavailable, inconclusive or outside the target you were placed in scope for is reported UNVERIFIED — never run, and never read as a negative result. gcx api is a diagnostic fallback, never the integration target.
  • Readiness — ready / backend prerequisite (named owner) / bounded bootstrap / not gcx. Unknowns block by material risk, not by category: an unknown bearing on API ownership or stability, auth/RBAC, security, mutation safety, correctness (including an unseen route or payload) or bounded completeness means backend prerequisite, and for those there is no "ready, pending verification". Any other unknown is recorded UNVERIFIED with its probe and the work continues. Full list in references/placement-and-readiness.md. Product teams own their API shape, auth, limits and domain data reduction; gcx wraps APIs, it does not fix them.

What this file has done since we first saw it

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.
