What it does

151 Java Performance Jmeter is an agent skill from jabrena/plinth. Use when you need to set up JMeter performance testing for a Java project — including creating the run-jmeter.sh script from the exact template, configuring load tests with loops, threads, and ramp-up, or running performance tests from the project root with custom or default settings. This should trigger for requests such as Improve the code with JMeter performance testing; Apply JMeter performance testing; Refactor the code with JMeter performance testing; Add JMeter support; Create a JMeter test plan for a Java…

Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/151-java-performance-jmeter.md` and `scripts/run-jmeter.sh`).

It sits in Testing & QA, covering Load testing. It works with Java. The repository describes itself as: Plinth is an AI-native engineering toolkit for modern Java enterprise SDLC, built around reusable Commands, Agents, Skills, and MCP Servers. The licence is Apache-2.0.

When your agent uses it

  • You need to set up JMeter performance testing for a Java project — including creating the run-jmeter.sh script from the exact template
  • Configuring load tests with loops
  • Running performance tests from the project root with custom
  • Default settings

Example prompts

  • “/151-java-performance-jmeter”

Requirements

  • A Bash shell

What it can do on your machine

Read from SKILL.md and the folder at commit dca88dc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Shell), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

151 Java Performance Jmeter loads about 842 tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 145 tokens; SKILL.md has 342 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~145
When it runs · the whole SKILL.md, loaded when a task matches
~842
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Run performance tests based on JMeter

Provide a complete JMeter performance testing solution by creating the run-jmeter.sh script from the exact template, making it executable, and configuring the project structure for load testing. Supports custom loops, threads, ramp-up, and environment variable overrides.

What is covered in this Skill?

  • Create run-jmeter.sh in project root from the exact template (no modifications)
  • Project structure: src/test/resources/jmeter/load-test.jmx, target/ for results
  • Script options: -l (loops), -t (threads), -r (ramp-up), -g (GUI), -h (help)
  • Environment variables: JMETER_LOOPS, JMETER_THREADS, JMETER_RAMP_UP
  • Verify JMeter is installed and available before proceeding

Scope: Copy the script template verbatim. Do not modify, interpret, or enhance the template content.

Constraints

JMeter must be installed and available in PATH. If not available, show a message and exit. Use only the exact template for the run-jmeter.sh script.

  • PREREQUISITE: Verify JMeter is installed and accessible via jmeter --version before creating the script
  • CRITICAL: Copy the run-jmeter.sh template exactly — do not modify, interpret, or enhance
  • PERMISSION: Make the script executable with chmod +x run-jmeter.sh
  • BEFORE APPLYING: Read the reference for the exact script template and usage instructions
  • EDGE CASE: If request scope is ambiguous, stop and ask a clarifying question before applying changes
  • EDGE CASE: If required inputs, files, or tooling are missing, report what is missing and ask whether to proceed with setup guidance

When to use this skill

  • Improve the code with JMeter performance testing
  • Apply JMeter performance testing
  • Refactor the code with JMeter performance testing
  • Add JMeter support
  • Create a JMeter test plan for a Java service

Workflow

  1. Verify JMeter prerequisite

Check jmeter --version and stop with guidance if JMeter is not installed or not available in PATH.

  1. Read JMeter reference template

Read references/151-java-performance-jmeter.md and use the run-jmeter.sh template exactly as provided.

  1. Create script and project structure

Create run-jmeter.sh in project root, ensure required JMeter directories/files exist, and apply executable permission with chmod +x.

  1. Explain usage and environment overrides

Document CLI options (-l, -t, -r, -g, -h) and environment variable overrides (JMETER_LOOPS, JMETER_THREADS, JMETER_RAMP_UP).
