Quality

Content

92%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 an exemplary lean alias stub: minimal, unambiguous, and correctly pointing one level deep to the real xlsx skill rather than duplicating or nesting content.

DimensionReasoningScore

Conciseness

The body is three lean lines with zero padding and no explanation of concepts Claude already knows, matching the "lean and efficient; every token earns its place" anchor.

5 / 5

Actionability

"Load and follow the `xlsx` skill body for the actual workflow" is a concrete, executable directive, but it lacks specific examples covering common cases, so it sits at the mostly-executable anchor rather than fully copy-paste ready.

4 / 5

Workflow Clarity

This is a single-purpose alias skill whose single action (load and follow xlsx) is unambiguous; the simple-skill exception applies and there are no destructive or batch operations requiring validation checkpoints.

5 / 5

Progressive Disclosure

The skill is under 50 lines with a single well-signaled one-level-deep reference (to the xlsx skill body) and no need for external bundle files, satisfying the simple-skill exception for a well-organized overview.

Description

48%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 is an intentionally minimal alias pointer: it clearly states the skill's role and targets the specific xlsx niche, but it lacks concrete capability actions and any explicit "use when" trigger guidance.

Suggestions

Add a "Use when working with .xlsx files, Excel spreadsheets, or tabular data" clause to supply explicit trigger terms and complete the what/when pair.

Briefly state the concrete actions the aliased xlsx skill performs (e.g., read, write, format spreadsheets) so the description is self-describing rather than only a redirect.

Include synonyms (Excel, spreadsheets, tabular data, .xlsx) to improve trigger-term coverage beyond the single "xlsx" keyword.

DimensionReasoningScore

Specificity

The description names the domain ("xlsx") but states no concrete actions of the skill itself, only that it is a compatibility alias — matching the "names the domain but actions are minimal or generic" anchor rather than the 3-anchor which requires 1-2 concrete actions.

2 / 5

Completeness

It gives a clear "what" ("Compatibility alias for the xlsx skill") but provides no "Use when..." trigger clause, so per the rubric a missing explicit trigger guidance caps completeness at 3.

3 / 5

Trigger Term Quality

"xlsx" is a relevant, specific keyword a user might say, but the description omits common variations and synonyms (spreadsheets, Excel, tabular data), matching the "some relevant keywords but missing common variations or synonyms" anchor.

3 / 5

Distinctiveness Conflict Risk

The "xlsx" niche is specific and unlikely to trigger unrelated skills, with only minor overlap risk against adjacent spreadsheet/tabular skills, matching the "mostly distinct; minor overlap risk" anchor.
