Conciseness

The body is lean with no over-explanation of concepts Claude already knows (it never explains what JMeter is) and every section carries information. It falls short of anchor 5 because of redundancy: the trigger-phrase list repeats the frontmatter verbatim in 'When to use this skill', and 'Copy the script template verbatim' appears in both the Scope line and the Constraints section.

Actionability

Concrete, executable guidance dominates: specific commands ('jmeter --version', 'chmod +x run-jmeter.sh'), exact paths (src/test/resources/jmeter/load-test.jmx, target/), CLI flags (-l, -t, -r, -g, -h), and named env vars (JMETER_LOOPS, JMETER_THREADS, JMETER_RAMP_UP). It stays at 4 rather than 5 because the actual script content is deferred to the reference rather than being copy-paste ready in place, and the bundle's scripts/run-jmeter.sh is never mentioned as a source.

Workflow Clarity

The 4-step workflow is clearly sequenced with an explicit validation checkpoint up front ('Check jmeter --version and stop with guidance if JMeter is not installed') and edge-case handling for ambiguous scope and missing tooling. It misses anchor 5 because validation exists only as a prerequisite — there is no post-creation verification step (e.g., running './run-jmeter.sh -h' to confirm the script works), which is a minor validation gap.

Progressive Disclosure

Good structure: the ~55-line body stays an overview and points to a real, clearly-signaled, one-level-deep reference (references/151-java-performance-jmeter.md, verified present, linked twice). Scored against the actual bundle, it loses a point because scripts/run-jmeter.sh (250 lines) exists in the bundle but is never referenced or navigated from SKILL.md, leaving it orphaned.

Specificity

Concrete actions are listed comprehensively — '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' — matching the anchor-5 example's breadth. However, the second-person phrasing 'Use when you need to set up...' triggers the rubric's voice penalty, reducing this by 1 to 4.

Completeness

Both 'what' (set up JMeter performance testing, create run-jmeter.sh from the exact template, configure loops/threads/ramp-up, run tests) and 'when' ('Use when you need to set up JMeter performance testing for a Java project' plus a concrete trigger-phrase list) are clearly and explicitly answered, matching the anchor-5 example structure.

Trigger Term Quality

Explicit trigger phrases ('Improve the code with JMeter performance testing; Apply JMeter performance testing; Add JMeter support; Create a JMeter test plan for a Java service') give good natural-term coverage with variations. A few natural terms are missing (e.g., 'load testing', 'stress test', '.jmx') and the first three triggers are near-duplicates of one phrasing pattern, so it falls just below the comprehensive anchor 5.

Distinctiveness Conflict Risk

The JMeter/Java niche is explicit with distinct triggers (run-jmeter.sh, JMeter test plan, load-test tooling), giving minimal overlap risk with other skills; anchor 5 is the closest fit and no neighboring anchor describes it better.
