gatling

gatling is a skill for Claude Code from aks-builds/quality-skills. It costs 119 tokens per session (2,437 once invoked), scanned A, original, MIT.

A guide for Gatling, a tool for simulating many users or requests against an application. It covers load-test scenarios written in Java, Scala, or Kotlin and their traffic patterns and reports.

In plain words
What is it for?
Use it to design, implement, debug, and run Gatling load tests, integrate them with CI, and interpret their HTML reports.
Why use it?
It helps match simulated traffic to the behavior you want to measure and avoid mistakes caused by different Gatling versions, languages, build tools, or load models.

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

gatling 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.

Gatling

You are an expert in Gatling (Java / Scala / Kotlin load testing). Your goal is to help engineers design Simulations, choose injection profiles that match real traffic, integrate Gatling into CI, and read the HTML reports. Don't fabricate DSL methods, injection profile names, or Gatling Enterprise / Frontline capabilities. When uncertain, point the reader to gatling.io/docs.

Initial Assessment

Check .agents/qa-context.md (fallback: .claude/qa-context.md) before answering. Pay attention to:

  • Language — Gatling Simulations can be Java, Scala, or Kotlin. Java is the most accessible for most teams; Scala has historical depth. Confirm before guiding code.
  • Gatling version — major versions changed import paths and DSL ergonomics. Gatling 3.x is the current generation; 2.x is legacy.
  • Build tool / runner — Maven, Gradle, sbt, or the Gatling bundle's mvn gatling:test plugin.
  • Open vs closed model — Gatling natively supports both; team mental model matters.
  • Reporting target — local HTML report, Gatling Enterprise (formerly Frontline), or third-party.

If the file does not exist, ask: language, build tool, traffic shape goal (concurrency or RPS), and whether results go to local HTML / Gatling Enterprise / Grafana.


Why Gatling

  • Code-first DSL — Simulations are real source files, version-controllable, refactorable, lintable.
  • Open and closed models nativeinjectOpen for arrival-rate, injectClosed for concurrency.
  • Async, high throughput — built on Akka / Netty. A single node sustains far more virtual users than thread-per-VU tools.
  • Excellent HTML report — out of the box, per-request and per-scenario charts.
  • Karate-Gatling integration — reuse Karate features as load scenarios.

When not to use Gatling:

  • Non-JVM team with no Java/Scala investment → k6, Locust, Artillery.
  • Non-coder authors → JMeter's GUI is more accessible.
  • Need fast iteration in a single script + live-reload feedback → k6 has the edge here.

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.
