testland/browser-matrix-runner

Configures a CI matrix that runs the smoke / regression suite across multiple browsers per Playwright's three-engine support (Chromium, Firefox, WebKit / Safari) plus branded variants (chrome, msedge channels). Wires GitHub Actions / GitLab CI matrix syntax, captures per-browser screenshots, and aggregates per-browser pass/fail. Use when the product targets multiple browsers and the team wants automated cross-browser testing or browser-compatibility regression - e.g. a 'works in Chrome, broken in Safari' bug that needs Chrome / Firefox / Safari coverage.

Quality

Content

85%

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 and workflow-clear with strong section organization and validation steps. Its only weakness is mild verbosity from quoting Playwright documentation verbatim rather than summarizing it.

Suggestions

Replace the verbatim block-quoted Playwright engine/channel documentation with a concise one-line summary per engine, keeping only the information Claude cannot infer.

Trim or fold the branded-channel list into the existing Step 1 install block so it is not duplicated between the Overview and Step 1.

DimensionReasoningScore

Conciseness

The body is largely lean and avoids explaining concepts Claude knows, but the verbatim block-quoted Playwright documentation (engine descriptions and the branded-channels list) is padding that could be tightened, matching the score-2 anchor.

2 / 3

Actionability

Provides fully executable, copy-paste-ready install commands, a complete playwright.config.ts projects block, a CI matrix YAML workflow, and run commands, matching the score-3 anchor.

3 / 3

Workflow Clarity

A clearly sequenced six-step process with an explicit validation checkpoint ('assert npx playwright install --with-deps exited 0 and a playwright-report/ artifact was produced') and an error-recovery feedback loop, matching the score-3 anchor.

3 / 3

Progressive Disclosure

Well-organized into clearly headed sections with easy navigation and signaled one-level-deep references (the [pwb] external link and sibling-skill references); for a self-contained skill with no bundle files, well-organized sections meet the score-3 bar.

Description

100%

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, well-triggered, complete, and distinctive. It clearly states concrete capabilities and provides an explicit, natural-language use trigger anchored by a relatable example bug.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('Configures a CI matrix', 'runs the smoke / regression suite', 'Wires GitHub Actions / GitLab CI matrix syntax', 'captures per-browser screenshots', 'aggregates per-browser pass/fail'), matching the score-3 anchor of multiple specific concrete actions.

3 / 3

Completeness

Explicitly answers both what it does and when to use it via a clear 'Use when...' clause with a concrete example bug, matching the score-3 anchor.

3 / 3

Trigger Term Quality

Includes natural phrases a user would say ('works in Chrome, broken in Safari', 'cross-browser testing', 'browser-compatibility regression', 'Chrome / Firefox / Safari'), giving good coverage of natural trigger terms.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche (Playwright cross-browser CI matrix with named engines/channels and a concrete Safari bug example), making it unlikely to conflict with generic testing skills.
