Quality

Content

85%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.

A well-structured instructional skill with clear sequencing, validation checkpoints, and clean one-level reference splitting. The main weaknesses are mild overview/section redundancy and the highest-value易错点 section leaning on an external example rather than an inline concrete illustration.

Suggestions

Trim redundancy between the 8-step 工作流程 overview and the later expanded sections — keep the overview as a brief roadmap and let the dedicated sections carry the detail.

Add a short inline worked illustration of the four-step 易错点 format (错法→为什么这么想→为什么错→怎么避免) so the skill's most important guidance is concrete without requiring examples.md.

Note fallback behavior in the MCP image-reading step (what to do if the image cannot be parsed or returns empty) to strengthen the input-validation feedback loop.

Dimension	Reasoning	Score
Conciseness	Assumes Claude's competence (no padding about what fractions or subjects are) and focuses on task-specific methodology, but the 8-step 工作流程 overview is re-expanded in later sections (第一步, 讲解结构, 易错点, 自检清单), creating mild redundancy that could be trimmed.	4 / 5
Actionability	Gives a copy-paste-ready MCP call with concrete prompt/params, explicit file-naming patterns, SVG path conventions, and a four-step 易错点 template — mostly executable, with the minor gap that the highest-value section relies on examples.md rather than an inline worked snippet.	4 / 5
Workflow Clarity	Clear 8-step sequence with explicit validation checkpoints: input confirmation (ask for grade if missing, echo image-derived question), and a交付前自检 checklist serving as a feedback gate before output — matching the checklist-for-complex-processes anchor.	5 / 5
Progressive Disclosure	Body is an overview that delegates detail to two real one-level-deep references (grade_levels.md for grade baselines, examples.md for a full worked example), each clearly signaled with a one-line purpose in the 资源 section; both files exist in ./references/.	5 / 5

Description

95%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.

A strong, well-targeted description that clearly states capability, output format, and concrete trigger conditions using natural user language. The only minor gap is action breadth — two core actions rather than a comprehensive multi-action list.

Dimension	Reasoning	Score
Specificity	Names two core concrete actions ("通俗讲解题目", "生成举一反三练习") plus concrete output artifacts (讲解文件/练习文件 in markdown/), but stops short of the multi-action comprehensive list a 5 would require.	4 / 5
Completeness	Explicitly answers both what (grade-appropriate explanation + 举一反三 practice, output as two markdown files) and when ("当用户给出年级 + 题目...希望得到讲解、辅导...时使用") with concrete trigger phrases.	5 / 5
Trigger Term Quality	Includes natural phrases a parent/teacher would actually say — "讲解", "辅导", "讲到孩子能听懂", "出同类练习题" — covering synonyms for both the explanation and practice-generation triggers.	5 / 5
Distinctiveness Conflict Risk	Clear niche (grade-locked student tutoring with practice generation) with distinct triggers (年级+题目, 讲到孩子能听懂, 举一反三) unlikely to fire for unrelated skills.	5 / 5
