testland/cloudflare-workers-miniflare

Wraps Miniflare 3 (the official Cloudflare Workers simulator) and Wrangler dev for testing Workers locally. Covers Miniflare's getMiniflare() programmatic API (workerd-backed simulation matching prod), the wrangler dev local-mode (live-reload during dev), KV / Durable Objects / R2 / D1 bindings emulation, and Vitest + @cloudflare/vitest-pool-workers for in-process tests. Use when testing Cloudflare Workers code locally.

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, fully actionable with executable code across all three testing patterns, and well-structured with clear sections and a one-level reference list. It assumes Claude's competence and avoids concept over-explanation.

DimensionReasoningScore

Conciseness

The body is lean: tight prose, copy-paste code blocks, and a dense anti-patterns table, without explaining basic concepts Claude already knows; every section earns its tokens. Borderline prose in the Overview adds specific fidelity context rather than generic padding, so it stays at 3 rather than dropping to 2.

3 / 3

Actionability

Provides fully executable, copy-paste-ready guidance: an npm install command, wrangler dev invocations, complete TypeScript Miniflare/vitest-pool-workers/DO/D1 examples, and a CI YAML workflow — matching the score-3 anchor.

3 / 3

Workflow Clarity

Three integration patterns are clearly sequenced (Overview → When to use → Authoring → Running → CI), with the tests themselves serving as the verification loop; no destructive batch operation lacks validation, so it is not capped at 2.

3 / 3

Progressive Disclosure

No bundle files exist, so scoring is on organization and signaling; sections are well-organized with a clear References block linking one-level-deep to external docs and companion skills, with no nested-reference chains.

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, third-person, and covers both capabilities and an explicit 'Use when' trigger with natural keywords. It clearly distinguishes the skill within the Cloudflare Workers testing niche.

DimensionReasoningScore

Specificity

Lists multiple concrete actions: 'Wraps Miniflare 3', 'Wrangler dev', 'getMiniflare() programmatic API', 'KV / Durable Objects / R2 / D1 bindings emulation', and 'Vitest + @cloudflare/vitest-pool-workers for in-process tests' — matching the score-3 anchor of multiple specific concrete actions.

3 / 3

Completeness

Explicitly answers both what (wraps Miniflare 3 and Wrangler dev for local Workers testing, covering named APIs/bindings) and when ('Use when testing Cloudflare Workers code locally'), satisfying the explicit-trigger requirement.

3 / 3

Trigger Term Quality

Includes natural terms a user would say — 'testing Cloudflare Workers code locally', 'Cloudflare Workers', 'Miniflare', 'Wrangler dev' — with good coverage rather than jargon-only phrasing.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche — Cloudflare Workers local testing — with distinct triggers unlikely to fire for unrelated skills; no overlap with generic code/document skills.
