Quality

Content

68%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 provides concrete, mostly-executable code organized into a clear four-step pipeline with lean, practical comments. Its main weakness is the absence of validation/verification checkpoints in a data-modifying workflow, which caps workflow clarity. Structure and progressive disclosure are solid for a focused single-file sub-skill.

Suggestions

Insert validation checkpoints between steps — e.g., after cleaning, assert row-count sanity / print df_clean.shape and non-null counts before analyzing; after regression, verify r_value and p_value are finite.

Add a minimal data-loading/setup snippet (read_excel + column selection) so the code blocks are fully copy-paste runnable rather than assuming a pre-existing df.

Optionally move the longer visualization code into a referenced scripts/ file and keep SKILL.md as a tighter overview to approach the top progressive-disclosure anchor.

DimensionReasoningScore

Conciseness

The body is efficient: concise Chinese step descriptions plus focused code, with comments that are practical tips (font config, utf-8-sig, jitter) rather than explanations of basic concepts; a few comments like '# 假设 target_col_x...' are minor padding, keeping it just below the lean 'every token earns its place' anchor.

4 / 5

Actionability

Each step ships concrete, executable pandas/matplotlib/scipy code with real calls (groupby/agg, pivot_table, linregress, savefig), but it assumes df and named columns already exist with no data-loading setup, so it is 'mostly executable with minor gaps' rather than fully copy-paste ready.

4 / 5

Workflow Clarity

Four steps are clearly sequenced (clean → analyze → visualize → export), but there are no validation checkpoints (e.g., verifying the cleaned dataset or sanity-checking stats), and the dropna/ffill cleaning is a data-modifying batch operation — per the rubric this caps workflow_clarity at 3.

3 / 5

Progressive Disclosure

Content is well organized into four labeled steps with a clearly signaled, one-level-deep reference to the parent workflow SKILL.md and no nested references; with no bundle files present and a focused single-file scope this is good structure, though it lacks the explicit overview/references split of the top anchor.

Description

53%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 clearly states what the skill does but omits any explicit 'Use when' trigger guidance, capping completeness at 3. Trigger-term coverage is decent but lacks file extensions and common synonyms. It is a fairly distinct Excel sub-skill.

Suggestions

Add an explicit trigger clause, e.g. 'Use when the user asks to analyze, summarize, or visualize Excel/.xlsx data, compute statistics, or generate charts from a spreadsheet.'

List concrete actions (pivot tables, crosstabs, regression/R², scatter/box plots) instead of the abstract phrase '多维度统计分析' to lift specificity.

Include natural synonyms and the .xlsx file extension among trigger terms for better keyword coverage.

DimensionReasoningScore

Specificity

The phrase "多维度统计分析与可视化" names the domain (Excel data) and two actions (statistical analysis, visualization), but they remain somewhat abstract rather than enumerating concrete operations like pivot tables, charts, or correlation — matching the 'names domain and 1-2 concrete actions' anchor; not 4 because it does not list several specific actions.

3 / 5

Completeness

It gives a clear 'what' (multi-dimensional statistical analysis and visualization of Excel data) but has no 'Use when...' or equivalent trigger clause, which per the rubric caps completeness at 3; not 2 because the 'what' is clear rather than vague.

3 / 5

Trigger Term Quality

It includes relevant natural terms such as "Excel 数据", "统计分析", and "可视化", but misses common variations users would say — .xlsx, 图表/charts, 透视表/pivot — so it fits 'some relevant keywords but missing common variations'; not 4 due to the synonym/extension gaps.

3 / 5

Distinctiveness Conflict Risk

Anchoring to Excel plus statistical analysis and visualization carves a fairly distinct niche with only minor overlap risk against the broader parent Excel workflow (reading/counting/Parquet); not 5 because the generic '统计分析' phrasing leaves some overlap with general data-analysis skills.
