Quality

Content

87%

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

The body is tight, concrete, and well-organized with an executable manifest skeleton and a precise API surface, so it scores at the top on conciseness, actionability, and structure. The only gap is workflow validation, which is mental rather than an explicit validate-and-retry loop.

DimensionReasoningScore

Conciseness

The body is lean throughout: it never explains what Chrome MV3 or a service worker is, and the file list, manifest skeleton, API surface, workflow, and guardrails each carry actionable weight with no padding.

3 / 3

Actionability

It provides a copy-paste-ready manifest.json skeleton and a specific list of supported chrome.* method names, giving fully executable guidance rather than pseudocode.

3 / 3

Workflow Clarity

The four numbered steps are clearly sequenced and include a checkpoint, but the verification ("Test mentally: walk through one user action and confirm every permission used is declared") is a mental check with no feedback loop for error recovery.

2 / 3

Progressive Disclosure

The skill is a single self-contained ~60-line file with clearly labeled sections (Required files, manifest skeleton, Supported APIs, Workflow, Don't) and no nested references, which is appropriate for a focused single-purpose skill.

Description

57%

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 concrete and distinctive but only names a single action and carries no explicit "Use when..." trigger, leaving completeness and trigger coverage at the middle level. The when_to_use field supplies triggers separately, but that guidance is not present in the evaluated description field itself.

Suggestions

Append a "Use when..." clause to the description (e.g., "Use when the user wants content scripts, declarativeNetRequest rules, or a popup UI") so completeness is explicit in the description field itself.

Expand the action list beyond "Build" to the concrete capabilities (e.g., "write content scripts, add declarativeNetRequest rules, build a popup UI") to lift specificity.

Add natural user-facing terms alongside the jargon, such as "browser extension" or "ad-blocking rules", to broaden trigger-term coverage.

DimensionReasoningScore

Specificity

The description names the domain ("Chrome MV3 extension", "WebToApp's MV3 runtime") and a concrete action ("Build"), but it lists only a single action rather than multiple specific concrete actions, so it stops short of the top anchor.

2 / 3

Completeness

It states what the skill does but the description field contains no "Use when..." clause or explicit trigger guidance, which per the judging guidelines caps completeness at 2.

2 / 3

Trigger Term Quality

"Chrome MV3 extension" is a term a user might say, but "WebToApp's MV3 runtime" is internal jargon and common variations ("browser extension", "ad blocker", "content script") are absent, matching the middle anchor.

2 / 3

Distinctiveness Conflict Risk

The narrow tie to WebToApp's MV3 runtime gives the skill a clear niche with distinct triggers, making it unlikely to fire for an unrelated skill.
