Quality

Content

71%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 body is a well-structured, reasonably concise workflow with a concrete, verified script-call contract that matches the bundled generator. Its two real defects are a dangling reference to a nonexistent reference.md and the absence of any post-generation verification step; a fully worked payload example would further strengthen actionability.

Suggestions

Fix or remove the dangling `reference.md` pointer — either add the referenced file (layout/colors/python-pptx details) to the bundle or drop the section that tells the agent to read it.

Add a post-generation validation step, e.g. confirm the output .pptx exists and contains the expected 8-12 slides before reporting success.

Include one fully worked payload example (a complete JSON with title, subtitle, and 2-3 slides) so the contract is copy-paste ready, and deduplicate the 8-12-page / 3-5-bullet rules stated in both the flow and the constraints section.

DimensionReasoningScore

Conciseness

The body is lean and free of concept explanations Claude already knows, but the 8-12 page count and 3-5 bullet rules are each stated twice (in the 规划页序 step and again in the 约束 section), so it sits at 'efficient; minor instances… that could be trimmed' rather than 'every token earns its place'.

4 / 5

Actionability

It gives the exact tool call signature (run_skill_script(name="pptx", script="generate_pptx.py", payload=...)) and a concrete payload JSON schema whose fields match the bundled generator script. It stops short of a fully worked filled-in payload example, leaving it at 'mostly executable guidance with minor gaps' rather than copy-paste ready.

4 / 5

Workflow Clarity

The four-step sequence (通读来源 → 规划页序 → 提炼要点 → 生成文件) is clear and enumerates the required slide structure explicitly. However there is no post-generation validation step (e.g., confirm the output file was created with the expected slide count), which is a minor checkpoint gap; the destructive/batch cap does not apply since this is a single generative, non-destructive script call.

4 / 5

Progressive Disclosure

The layered structure is good in principle (core flow in SKILL.md, details deferred to `reference.md` and `scripts/generate_pptx.py`, one level deep), but the bundle actually contains only scripts/generate_pptx.py — `reference.md` does not exist, so the pointer is a dead reference that would fail when an agent follows it. Per the guideline to score against the actual bundle structure, this lands at 'some structure but could be better organized' with a broken reference.

Description

90%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 description: concrete what, explicit when with rich natural-language trigger terms (Chinese and English synonyms plus the .pptx extension), and a Don't-use clause that sharply delimits scope. The only limitation is that it describes a single action rather than a broader action set, which is partly by design given the exclusions.

DimensionReasoningScore

Specificity

The description states one domain with one concrete action — "从论文、大纲或结构化文本生成 PowerPoint (.pptx) 演示文稿" — naming the input types and output format, but covers only generation with no companion actions, matching the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'. Score 4 would require several distinct specific actions; the single generate action keeps it at 3.

3 / 5

Completeness

It clearly answers both what ("从论文、大纲或结构化文本生成 PowerPoint (.pptx) 演示文稿") and when ("Use when 用户需要把一篇论文/文章/大纲做成幻灯片…") with concrete trigger phrases, and adds an explicit Don't-use boundary. This matches the anchor for a complete what+when description with concrete triggers.

5 / 5

Trigger Term Quality

Trigger coverage is comprehensive with natural synonyms and the file extension: "幻灯片、slides、演示文稿、PPT、deck" plus ".pptx" and "PowerPoint". This matches the anchor 'Comprehensive coverage of natural terms including synonyms and file extensions'; nothing common is missing.

5 / 5

Distinctiveness Conflict Risk

It carves a clear niche (generating .pptx from papers/outlines) and actively reduces conflict with the exclusion "Don't use when 只需纯文本总结、生成 Word/PDF、或修改已有 pptx 的单个像素级样式". Minimal overlap risk, matching the 'clear niche with distinct triggers' anchor.
