Quality

Content

72%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.

The content is a concise, well-structured reference for a single-purpose skill with executable examples and a clear parameter table. Its main weakness is the absence of any validation or safeguard for a destructive page-deletion operation.

Suggestions

Add a verification/safety step before deletion, e.g. confirm page_nums are within the document's page range and warn that deletion is irreversible, to raise workflow_clarity above 3.

Cover common edge cases in the example (out-of-range indices, deleting the last page) to lift actionability toward 5.

De-duplicate the repeated `from skills.pdf import del4pdf` import shown in both '调用方式' and '使用示例' to tighten conciseness.

Dimension	Reasoning	Score
Conciseness	The body is lean and mostly efficient with clear sections, but the '功能描述' section restates the title and both '调用方式' and '使用示例' repeat the same import, adding minor redundancy; not a 5 because of these small duplications and not a 3 because no Claude-known concepts are over-explained.	4 / 5
Actionability	Provides an executable, copy-paste-ready call with a parameters table and a concrete worked example; it is not a 5 because edge cases (page ranges, invalid indices, missing files) are not covered, and not a 3 because the given code is fully executable rather than pseudocode.	4 / 5
Workflow Clarity	Page deletion is a destructive operation yet no validation or verification step (e.g., confirming page_nums are in range, checking the output opened correctly) is present, so workflow_clarity is capped at 3 per the destructive-operations guideline; not a 4 because of the missing checkpoint and not a 2 because the single-step sequence is coherent.	3 / 5
Progressive Disclosure	For a simple single-purpose skill under 50 lines with no need for external references, the well-organized sections (功能描述, 参数说明, 使用示例) provide clear navigation and structure, matching the simple-skill exception for a top score.	5 / 5

Description

78%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.

The description cleanly answers both what the skill does and when to use it, with natural Chinese trigger phrases that a user would realistically say. It is concise and appropriately specific for a single-purpose skill.

Suggestions

Add the .pdf file extension and one or two more natural phrasings (e.g., '删掉 PDF 的某些页') to lift trigger_term_quality toward comprehensive coverage.

Consider noting the destructive nature ('permanently removes pages') to further sharpen distinctiveness from other PDF skills.

Dimension	Reasoning	Score
Specificity	Names the PDF domain and one concrete action ('删除 PDF 文件中指定的页面'), matching the 'names domain and 1-2 concrete actions' anchor; it is not a 4 because only a single action is covered and not a 2 because the action is concrete rather than generic.	3 / 5
Completeness	Explicitly states both what it does ('删除 PDF 文件中指定的页面') and when to use it ('当用户提到 PDF 删除页、PDF 删页、删 PDF 页时使用') with concrete trigger phrases, matching the top anchor.	5 / 5
Trigger Term Quality	Includes several natural user phrases ('PDF 删除页、PDF 删页、删 PDF 页') with synonym variation; it is a 4 rather than 5 because file extensions like .pdf and additional common phrasings are absent, and not a 3 because multiple natural terms are present.	4 / 5
Distinctiveness Conflict Risk	The delete-pages niche is mostly distinct with specific triggers and low conflict risk; it is not a 5 because it could still overlap with broader PDF-manipulation skills, and not a 3 because the scope is narrower than 'works with document files'.	4 / 5
