Quality

Content

100%

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

The content is concise, actionable, and well-sequenced with explicit validation checkpoints and a clear feedback loop. It is an exemplary instruction-only skill body with no significant weaknesses.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence, with no padding or explanations of concepts Claude already knows; every section earns its place.

3 / 3

Actionability

Gives concrete, specific guidance — named APIs (showSaveFilePicker, createWritable, URL.createObjectURL), exact commands (pnpm --filter @open-design/web typecheck), and specific file extensions — rather than vague direction.

3 / 3

Workflow Clarity

The 'Fix order' is a clear numbered sequence with an explicit checkpoint (prove payload is non-zero before debugging destination) and a Validation section with a feedback loop (run tests → typecheck → pnpm guard → inspect diff).

3 / 3

Progressive Disclosure

A focused single-purpose skill under 50 lines with no need for external references; its well-organized sections (Core rule, Evidence, Fix order, Validation) meet the simple-skill bar for a top score.

Description

82%

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, distinct, and rich in natural trigger terms, but it omits an explicit 'Use when...' clause, which limits completeness. Adding a one-line usage trigger would lift the completeness dimension.

Suggestions

Append an explicit 'Use when...' clause, e.g. 'Use when an export or download runs but yields an empty, missing, or 0 KB file, or when showSaveFilePicker/createWritable fails.'

Add common user phrasings like 'download failed' or 'exported image is blank' to broaden natural trigger coverage.

DimensionReasoningScore

Specificity

Names concrete actions ('Diagnose and fix') plus multiple specific failure modes (Save As, Blob/Data URLs, File System Access API, createWritable failures, 0 KB files), matching the 'multiple specific concrete actions' anchor.

3 / 3

Completeness

It clearly states what the skill does but lacks an explicit 'Use when...' clause or equivalent trigger guidance, which caps completeness at 2 per the guidelines.

2 / 3

Trigger Term Quality

Includes natural terms users would say such as 'export/download failures', 'image export issues', 'Save As', 'createWritable', 'blob URL', and '0 KB files', giving good coverage.

3 / 3

Distinctiveness Conflict Risk

It carves a clear niche (export/download debugging in browser previews, iframe capture, and Electron) with distinct triggers unlikely to conflict with other skills.
