The body is a lean, numbered workflow of actionable bullets with only brief justifying rationale (e.g., "so baseline update scripts do not attempt to verify unsupported versions"); it assumes Claude's competence and avoids explaining concepts Claude already knows.

It gives concrete, executable commands and exact targets — `./gradlew testClasses`, `git rm -r tool/baseline/<version>`, `sinceBuild=252`, `grep` over `src/` — making the guidance copy-paste ready rather than abstract.

The 8-step sequence is clearly ordered with explicit validation checkpoints — a baseline `testClasses` run in step 1 and a full verify step (testClasses, test, verifyPlugin) in step 8 — matching the anchor for clear sequencing with validation.

The body is well under 50 lines, single-purpose, and cleanly organized into numbered sections with no need for external references; per the rubric's simple-skills note this earns a 3 on organization alone, and no bundle files exist to verify.

The description lists multiple concrete actions — "Remove support for an older IntelliJ Platform / Android Studio version" and "clean up obsolete code, baselines, and CI configurations" — matching the anchor for enumerating several specific actions rather than a single vague one.

It clearly answers "what" the skill does but provides no "Use when..." or equivalent explicit trigger guidance for "when", which the rubric guidelines cap at 2.

It surfaces domain-relevant terms ("IntelliJ Platform / Android Studio version", "baselines", "CI configurations") but lacks common natural variations a user might say (e.g., "drop support", "deprecate platform version") and has no explicit trigger phrasing, so it is not a full 3.

The niche is narrow and explicit — removing an IntelliJ Platform / Android Studio version — making it unlikely to fire for unrelated skills, matching the clear-niche anchor.
