Quality

Content

88%Weight 40%Scale 1-5

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

The body is highly actionable and well-sequenced with strong validation and recovery loops, making it an effective executable workflow. The only meaningful gaps are minor redundancy and a large single-file footprint that could be split.

DimensionReasoningScore

Conciseness

The body is lean—commands with brief 'Assert:' lines—and assumes Claude's competence (no XR/grab concept explanations), but the trigger-vs-squeeze distinction is restated three times (Component Reference, Critical Distinction note, and Known Issues), which could be trimmed.

4 / 5

Actionability

Every step is a copy-paste-ready 'npx iwsdk' command with concrete JSON payloads, and the examples cover all five suites including the common cases, matching the fully-executable anchor.

5 / 5

Workflow Clarity

Steps 1–5 are explicitly sequenced with per-command 'Assert:' validation checkpoints, plus a Recovery section with restart-and-retry feedback loops and a final summary checklist, matching the clear-sequence-with-explicit-validation anchor.

5 / 5

Progressive Disclosure

The content is self-contained with no nested references and is organized into clear sections (suites, Component Reference, Known Issues), but at ~430 lines with no external split it is above the simple-skill threshold, so it sits just below the well-signaled-reference anchor.

Description

62%Weight 40%Scale 1-5

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

The description is specific and clearly distinct but lacks an explicit trigger/use-when clause, which caps its completeness and trigger-term quality. Adding a 'Use when...' sentence would lift the two capped dimensions.

Suggestions

Append a 'Use when...' clause, e.g. 'Use when testing grab interactions or validating the grab example with the iwsdk CLI.'

Add a few natural trigger synonyms ('grab interactions', 'XR grab testing', 'distance/near-field grab') to broaden keyword coverage.

Consider naming the additional suites the body covers (system/component registration, stability) so the 'what' is fully comprehensive.

DimensionReasoningScore

Specificity

The description names the domain and enumerates three concrete subsystems ('distance grab, one-hand grab, two-hand grab') plus the tool ('iwsdk CLI'), but uses a single action verb ('Test') rather than multiple distinct actions, so it falls just below the comprehensive-coverage anchor.

4 / 5

Completeness

It clearly states what the skill does ('Test grab system... against the grab example using the iwsdk CLI') but provides no 'when to use it' guidance; per the judging guidelines, a missing 'Use when...' clause caps completeness at 3.

3 / 5

Trigger Term Quality

Terms like 'grab system', 'distance/one-hand/two-hand grab', and 'iwsdk CLI' are natural for this niche, but there is no trigger phrasing and no synonyms or common variations, leaving keyword coverage incomplete.

3 / 5

Distinctiveness Conflict Risk

The narrow XR grab-testing niche with iwsdk-specific terminology gives it a clear, distinct trigger set with minimal overlap risk against other skills.
