Quality

Content

57%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.

Actionable and concrete with a sensible numbered workflow, but it is undermined by inlining code that already exists as bundle scripts (never linked), and by the absence of a download-validation checkpoint for a batch operation.

Suggestions

Add a validation step after bulk download — verify expected vs. actual file count and non-zero sizes, then retry failures — so the batch workflow earns a higher workflow_clarity score.

Replace the inlined bash/JS snippets with signaled one-level-deep references to the existing scripts/download_gallery.sh and scripts/extract_patterns.js (e.g., '## Bulk download — run scripts/download_gallery.sh'), keeping only minimal inline examples in the overview.

Tighten the iframe batch section and remove duplicated selector-detection logic that already lives in scripts/extract_patterns.js to reduce token redundancy.

DimensionReasoningScore

Conciseness

Mostly efficient and code-forward, but several long JS snippets (and the iframe batch script) are inlined while a duplicate copy lives in the unreferenced scripts/ bundle, adding redundancy that could be tightened.

3 / 5

Actionability

Provides concrete, executable JS/bash/python snippets with real selectors and commands covering the common cases, with only minor placeholder gaps (SITE_DOMAIN/CDN_URL to substitute).

4 / 5

Workflow Clarity

Steps are clearly numbered (attach → discover → extract → paginate → download) but this batch download operation has no validation checkpoint verifying files landed intact or counts match; the reactive Troubleshooting section is not a verify-and-retry loop, capping the score per the rubric.

3 / 5

Progressive Disclosure

The body inlines most code despite scripts/download_gallery.sh and scripts/extract_patterns.js existing in the bundle, and neither script is referenced or signaled from the body, so content that belongs in separate files is inlined and references are buried/absent.

Description

92%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.

A well-crafted description that concisely names the capability and gives explicit, natural trigger guidance for an authenticated-gallery scraping niche. Only minor room to expand trigger synonyms.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Bulk download images', 'extract full-size images from thumbnails', 'batch download from multi-page galleries' — with comprehensive coverage of the gallery-download domain.

5 / 5

Completeness

Clearly states the what ('Bulk download images from login-protected gallery websites using an attached browser session') and an explicit 'Use when...' clause with concrete trigger scenarios.

5 / 5

Trigger Term Quality

Strong natural triggers ('scrape, download, or save images', 'authenticated gallery pages', 'batch download') with synonyms, but file-extension-style triggers are not applicable here and a couple of natural phrasings could be added.

4 / 5

Distinctiveness Conflict Risk

Targets a clear niche ('login-protected gallery websites', 'attached browser session') with triggers unlikely to collide with other skills.
