151-java-performance-jmeter

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 service.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

Well-structured, actionable body with a clear validated workflow and appropriate one-level-deep reference usage. The main weakness is internal duplication of the JMeter-verification and script-option points.

Suggestions

State the 'verify JMeter is installed' prerequisite once in the workflow instead of repeating it across the overview, constraints, and workflow steps.

Consolidate the script options (-l, -t, -r, -g, -h) and environment variables into a single location rather than listing them in both 'What is covered in this Skill?' and Workflow step 4.

DimensionReasoningScore

Conciseness

Mostly efficient and free of concept explanations Claude already knows, but the body duplicates key points internally — 'verify JMeter is installed' appears in the overview, constraints, and workflow, and the script options/env vars are listed in both 'What is covered' and Workflow step 4.

2 / 3

Actionability

Provides concrete executable commands ('jmeter --version', 'chmod +x run-jmeter.sh'), specific CLI options (-l, -t, -r, -g, -h) and env vars (JMETER_LOOPS, JMETER_THREADS, JMETER_RAMP_UP), plus a precise pointer to the script template in the reference.

3 / 3

Workflow Clarity

A four-step sequence with an explicit prerequisite validation ('Check jmeter --version and stop with guidance if JMeter is not installed') and edge-case feedback loops (ask a clarifying question if scope is ambiguous; report missing inputs).

3 / 3

Progressive Disclosure

A lean overview that defers the script template to a single real reference file (references/151-java-performance-jmeter.md), clearly signaled in the constraints, workflow, and a final Reference section — one level deep with easy navigation.

Description

90%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description with explicit triggers and a clear niche. The only weakness is second-person voice ('you need to'), which the rubric penalizes on specificity.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('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'), which would merit 3, but opens with second-person voice 'Use when you need to...', which the rubric penalizes by reducing specificity by one.

2 / 3

Completeness

Explicitly answers both what (set up JMeter testing, create the script, configure load tests, run tests) and when ('Use when you need to set up JMeter performance testing...', 'This should trigger for requests such as...').

3 / 3

Trigger Term Quality

Provides five natural trigger phrases a user would say ('Add JMeter support', 'Create a JMeter test plan for a Java service', 'Apply JMeter performance testing') with good coverage of common variations.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche (JMeter performance testing for Java projects) with distinct, specific triggers unlikely to conflict with other skills.
