Content

77%

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 with a clearly sequenced, validated workflow and strong recovery guidance. Its main weaknesses are repetition that inflates token count and a monolithic structure that could split per-suite detail into reference files.

Suggestions

Reduce repetition by stating shared conventions once (e.g. 'all commands run from $EXAMPLE_DIR and use `2>/dev/null`') instead of repeating the cd path and redirect on every block.

Move the per-suite assertion details or the Known Issues section into a references/ file (e.g. KNOWN_ISSUES.md) and link to it, enabling progressive disclosure and a leaner SKILL.md.

Trim explanatory notes that restate command behavior (e.g. 'Wait for this to complete before proceeding.') where the next numbered step already implies sequencing.

DimensionReasoningScore

Conciseness

Mostly efficient with concrete commands and minimal concept explanation, but it is repetitive (every command carries `2>/dev/null` and full `cd $IWSDK_REPO_ROOT/examples/physics` paths) and some notes could be tightened without losing clarity.

2 / 3

Actionability

Fully executable `npx iwsdk ...` commands with exact `--input-json` payloads, specific assertions on named fields and values, and copy-paste-ready blocks per test.

3 / 3

Workflow Clarity

Clear Step 1–5 sequence with explicit validation checkpoints (parse JSON, verify assertions before proceeding), early-exit branches (server failure → report FAIL and skip to Step 5), and a retry feedback loop in the Recovery section.

3 / 3

Progressive Disclosure

Well-sectioned but monolithic: the entire ~300-line procedure (5 suites, recovery, known issues) lives inline in SKILL.md with no references to separate files, and no bundle files are present to offload detail.

Description

67%

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 occupies a clear, low-conflict niche, but it omits explicit "Use when..." trigger guidance and leans on technical jargon over natural user phrasing. Adding a trigger clause would lift both completeness and trigger-term quality.

Suggestions

Append a 'Use when...' clause, e.g. 'Use when verifying the physics example, testing gravity or body dynamics, or debugging Havok physics behavior.'

Soften jargon with natural phrasing users would say, such as adding 'physics engine', 'collision', or 'falling objects' alongside 'Havok' and 'rigid bodies'.

Mirror common user phrasings like 'physics isn't working' or 'bodies not falling' to improve trigger-term coverage.

DimensionReasoningScore

Specificity

Names concrete test targets — "gravity, rigid bodies, static vs dynamic" — plus the specific tool ("iwsdk CLI") and fixture ("physics example"), listing multiple specific concrete actions rather than vague language.

3 / 3

Completeness

Clearly states what the skill does (test the Havok physics system) but lacks any "Use when..." clause or equivalent trigger guidance, capping completeness at 2 per the rubric guidelines.

2 / 3

Trigger Term Quality

Contains some natural terms a user would say ("physics", "gravity", "static vs dynamic") but is mixed with engine-specific jargon ("Havok", "iwsdk CLI", "rigid bodies") and is missing common variations a user might phrase casually.

2 / 3

Distinctiveness Conflict Risk

The niche is narrow and specific (Havok physics testing within the iwsdk CLI against a physics example), making it unlikely to trigger for unrelated skills.
