Quality

Content

80%

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

A concise, actionable skill body with executable curl examples and a clear service-comparison table. It is weakened by implicit fallback checkpoints between services and a reference to a nonexistent fetch.sh script.

Suggestions

Add explicit fallback checkpoints: define what counts as a failure (empty body, error/HTTP status, Cloudflare challenge page) and instruct trying markdown.new then defuddle.md in sequence only when the prior service fails.

Either provide the referenced fetch.sh script in a scripts/ directory or remove the "工具脚本" section; as written it points Claude to a file that does not exist.

Reconcile the conflicting command interfaces — the "API 格式" block shows `fetch_webpage <url> --method jina|markdown|defuddle` (flags) while fetch.sh is invoked with positional args (`./fetch.sh https://example.com jina`); pick one and document it consistently.

Dimension	Reasoning	Score
Conciseness	The body is lean: a service-comparison table, copy-paste curl commands, a short API-format block, and a minimal example, with no explanation of concepts Claude already knows (what curl or markdown is).	3 / 3
Actionability	It provides fully executable, copy-paste-ready commands (e.g. `curl -s "https://r.jina.ai/https://example.com"") with specific service URLs, matching the score-3 anchor for executable guidance.	3 / 3
Workflow Clarity	A two-step sequence is present ("1. 首先用 web_fetch 尝试获取 2. 如果失败或被过滤，调用本工具"), but the criteria for moving between the three fallback services are only implied by the priority table, with no explicit failure checks or checkpoints.	2 / 3
Progressive Disclosure	Sections are well organized for a short skill, but the body references a `fetch.sh` script ("本目录包含 `fetch.sh` 脚本") that does not exist in any bundle directory, making the sole external reference broken.	2 / 3

Description

82%

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 strong description that clearly states purpose, lists three concrete services with their roles, and provides explicit trigger words in both languages. Its main weakness is a single narrow capability and somewhat generic fetch triggers that could overlap with general web-fetch skills.

Dimension	Reasoning	Score
Specificity	Names the domain and three concrete services ("r.jina.ai - 最稳定", "markdown.new - Cloudflare 专用", "defuddle.md - 备用方案"), but the capability is a single action (fetching web content) with three methods rather than multiple distinct actions like the score-3 anchor's extract/fill/merge.	2 / 3
Completeness	It states what the skill does ("使用替代服务获取网页内容" with the three services) and when to use it ("当常规爬虫被过滤时" plus the trigger-word clause), clearly answering both what and when with explicit triggers.	3 / 3
Trigger Term Quality	An explicit 触发词 list provides five natural bilingual terms ("获取网页内容、网页转markdown、内容抓取、fetch webpage、bypass cloudflare") that a user would plausibly say, matching the score-3 anchor's good coverage.	3 / 3
Distinctiveness Conflict Risk	The bypass/filtering niche is reasonably specific, but the trigger terms "fetch webpage" and "获取网页内容" are generic enough to overlap with a general web-fetch skill, so it could still trigger the wrong skill.	2 / 3
	Total	10 / 12 Passed
