Conciseness

The body is dense and operational — every step is a concrete command with expected assertions, and it assumes Claude's competence (no explanation of what a dev server or ECS is). It misses anchor 5 due to duplicated content: the trigger-vs-squeeze distinction is stated nearly verbatim twice (the 'Critical Distinction' note under Component Reference and the 'Trigger vs Squeeze confusion' entry under Known Issues), and the GrabSystem priority -3 assertion also appears twice.

Actionability

Every instruction is a copy-paste-ready command with exact JSON payloads, timeouts, sleep intervals, and explicit assertions (e.g., 'Assert: Both Hovered and Pressed present', 'GrabSystem present at priority -3'). Placeholders (<distance>, <onehand-pos>, etc.) are defined through a concrete discovery procedure, so the commands are fully executable end to end.

Workflow Clarity

A clear five-step sequence with validation checkpoints throughout: connectivity verification before testing, per-test assertions, explicit failure handling ('If the server fails to start within 60 seconds, report FAIL for all suites and skip to Step 5'), a retry/feedback loop in the Recovery section, and a final summary-table reporting format. This matches the anchor with explicit validation, error-recovery loops, and a checklist-style structure.

Progressive Disclosure

The skill is self-contained (no references/, scripts/, or assets/ bundle exists) with well-organized sections, clear headers, a component reference table, and a distinct Known Issues section — good structure with content appropriately placed for a single-purpose test procedure. It falls short of anchor 5 because a few blocks (the Known Issues & Workarounds and the Component Reference table) are the kind of lookup material that could live in a separate reference file, and the ~437-line body exceeds the size where a single file is unambiguously the right choice; it is not 3 because nothing is buried and the organization is clean.

Specificity

The description names concrete, specific capabilities — 'Test grab system (distance grab, one-hand grab, two-hand grab) against the grab example using the iwsdk CLI' — listing three test targets, the test subject, and the tool. It falls just short of anchor 5 because it omits two of the five suites the body actually covers (system/component registration and stability).

Completeness

The 'what' is clear (test the grab system's three grab modes against the grab example via the iwsdk CLI), but there is no 'Use when...' clause or equivalent trigger guidance — the when to use it is entirely missing. Per the rubric guideline, a missing 'Use when' clause caps completeness at 3; it is not 2 because the 'what' half is specific and concrete.

Trigger Term Quality

It contains the natural terms a user would say ('test grab system', 'distance grab', 'one-hand grab', 'two-hand grab', 'iwsdk CLI'), giving good keyword coverage. A few natural variations are missing (e.g., 'grabbing', 'XR interaction', 'hand interaction'), keeping it below the comprehensive anchor 5.

Distinctiveness Conflict Risk

'Grab system', 'grab example', and 'iwsdk CLI' carve out a distinct niche with minimal conflict risk against generic skills. It is not 5 because other iwsdk test skills (e.g., other example test suites) could share overlapping trigger phrasing around 'test ... using the iwsdk CLI'.
