testland/print-stylesheet-tests

Test CSS print-media output via Playwright `page.emulateMedia({ media: 'print' })` + `page.pdf()` - `@page` rule (size, margin, orphans, widows), `@page :first / :left / :right` pseudo-classes, `break-before/after/inside`, `@media print` selector activation, page-break suppression on headings. Use when an app exposes a Print button or a print stylesheet exists but is untested, and users report the printed or PDF copy breaking in the wrong places while the on-screen page looks fine.

Quality

Content

85%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.

Well-structured, actionable content with executable Playwright test patterns, a clearly sequenced workflow with assertion checkpoints and a worked debugging loop, and proper offloading of advanced material to a one-level-deep reference file. Minor issues — redundant doc-citation restatements and undefined PDF-inspection helpers — keep conciseness and actionability just short of top marks.

Suggestions

Remove duplicated doc-citation restatements (e.g., the printBackground default is stated twice in Step 6) and trim commentary asides like 'the canonical print bug' to reduce token overhead.

Name a concrete PDF-inspection library or provide one-line stubs for the helper functions (getPdfPageCount, extractTextPerPage, renderPdfPage, getPdfDimensions) so the test examples are copy-paste runnable without the pdf-snapshot-tester sister skill.

Dimension	Reasoning	Score
Conciseness	Prose is mostly tight and focused on non-obvious API defaults ("preferCSSPageSize: true lets CSS @page { size: A4 } win over the API format option"), but Step 6 states the printBackground default twice ("By default printBackground: false" and "Per the [Playwright page.pdf docs]: printBackground defaults false") and asides like "the canonical print bug" could be trimmed.	4 / 5
Actionability	Six concrete Playwright test blocks with specific options (preferCSSPageSize, printBackground, format: 'A4') and a step-by-step worked example, but the PDF-inspection helpers (getPdfPageCount, extractTextPerPage, renderPdfPage, getPdfDimensions) are never defined — "Use a PDF inspector lib or pair with pdf-snapshot-tester" — so the examples are not copy-paste runnable.	4 / 5
Workflow Clarity	A 7-step 'How to use' overview is expanded into sequenced, assertion-backed steps, and the worked example demonstrates an explicit feedback loop: page-count assertion fails (3 vs baseline 2) → extractTextPerPage pinpoints the split totals table → re-add break-inside: avoid → re-run passes.	5 / 5
Progressive Disclosure	The core workflow stays inline while advanced @page geometry (pseudo-classes, margin precedence) is split into the real references/page-geometry.md, clearly signaled from a dedicated section, How-to step 7, the anti-patterns table, and the References list — one level deep, easy to navigate.	5 / 5

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 highly specific, well-triggered description that names the exact Playwright APIs and enumerates the print-CSS test surface, backed by an explicit 'Use when' clause with concrete scenarios. The only weakness is slightly incomplete natural-synonym coverage for trigger terms.

Dimension	Reasoning	Score
Specificity	Names exact API actions ("page.emulateMedia({ media: 'print' }) + page.pdf()") and enumerates concrete test targets ("@page rule (size, margin, orphans, widows)", "@page :first / :left / :right pseudo-classes", "break-before/after/inside", "@media print selector activation, page-break suppression") with no coverage gaps.	5 / 5
Completeness	Explicitly answers what ("Test CSS print-media output via Playwright...") with an enumerated feature list, and when ("Use when an app exposes a Print button or a print stylesheet exists but is untested, and users report the printed or PDF copy breaking...") with concrete trigger scenarios.	5 / 5
Trigger Term Quality	Natural user phrases are present ("Print button", "print stylesheet", "printed or PDF copy breaking in the wrong places", "on-screen page looks fine"), but common synonyms and extensions like "PDF export", "print preview", or ".pdf" are missing.	4 / 5
Distinctiveness Conflict Risk	Clear niche — automated testing of print-media CSS via Playwright's emulateMedia/pdf APIs — with distinct triggers ("Print button", "print stylesheet", "printed copy breaking") that are unlikely to fire for general PDF-manipulation or generic Playwright skills.	5 / 5
