testland/vercel-edge-runtime-testing

Wraps Vercel Edge Runtime testing patterns: the @edge-runtime/jest-environment + edge-runtime CLI for executing Web-Standard APIs (Request / Response / fetch) in jest tests, the `vercel dev` local emulator for full route testing, and the Edge vs Node Function divergence (no fs, no Buffer; Request / Response only). Covers the 30s Edge function timeout per vercel.com/docs. Use when testing Vercel Edge Functions or middleware.

Quality

Content

100%

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

A tight, highly actionable skill body built from executable code examples and a useful anti-patterns table, with a clear authoring-to-CI workflow and well-organized one-level references. It respects token budget while remaining concrete.

DimensionReasoningScore

Conciseness

The body is lean: mostly executable code, a compact anti-patterns table, and brief prose that ties constraints to testing rather than padding. It assumes Claude's competence and does not belabor basic concepts, fitting the lean-and-efficient anchor; not a 2 because there is no extraneous explanation to tighten.

3 / 3

Actionability

Provides copy-paste-ready, executable guidance throughout: install commands, jest config, a full Edge handler + its test, middleware + tests, vercel dev and edge-runtime CLI usage, and a CI workflow, matching the fully-executable anchor.

3 / 3

Workflow Clarity

The process is clearly sequenced (Install → Jest config → write handler → test → middleware → vercel dev → Running → CI), and running 'npx jest' supplies an inherent pass/fail validation checkpoint. This is not a destructive/batch operation requiring an explicit validate-fix-retry loop, so the clear-sequence anchor holds.

3 / 3

Progressive Disclosure

Content is organized into well-signaled sections with one-level-deep external URL references in a References section and no nested/deep reference chains; no bundle files exist to verify, so the well-organized-sections criterion for single-file skills applies.

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.

A specific, well-scoped description that states concrete capabilities, includes an explicit 'Use when' trigger, uses third-person voice, and occupies a distinct niche. It avoids vague fluff while staying concise.

DimensionReasoningScore

Specificity

Names multiple concrete actions: '@edge-runtime/jest-environment + edge-runtime CLI for executing Web-Standard APIs ... in jest tests', 'vercel dev local emulator for full route testing', and the Edge vs Node divergence (no fs, no Buffer), plus the 30s timeout. This matches the anchor that lists multiple specific concrete actions.

3 / 3

Completeness

Explicitly answers both what (wraps the testing patterns/tools) and when via the clause 'Use when testing Vercel Edge Functions or middleware', satisfying the anchor requiring explicit triggers for both.

3 / 3

Trigger Term Quality

Includes natural terms a user would say — 'testing Vercel Edge Functions or middleware', 'jest tests' — alongside the technical package names, giving good coverage of common phrasings rather than only jargon.

3 / 3

Distinctiveness Conflict Risk

Targets a clear niche (Vercel Edge Runtime testing) with distinct triggers unlikely to overlap with generic testing or Node skills, matching the clear-niche anchor.
