spreadsheets

Create, edit, inspect, transform, render, and verify standalone XLSX, XLS, CSV, and TSV files. Use for spreadsheet generation, formatting, formulas, charts, data consolidation, source-based calculations, numeric reconciliation, legacy conversion, and visual QA. Do not use for live control of Microsoft Excel or macro-enabled workbook editing.

Quality

Content

100%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, executable workflow that assumes competence, provides concrete commands at every stage, enforces review/verification checkpoints, and pushes detail into verified one-level-deep references. It is concise, actionable, and well-organized throughout.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence: it never explains what a spreadsheet or formula is, uses terse imperative guidance, and every section earns its tokens, matching the 'lean and efficient; assumes Claude's competence; every token earns its place' anchor.

5 / 5

Actionability

It provides fully executable, copy-paste-ready bash commands with real flags and paths (inspect, scaffold, build, review, evaluate, deliver) plus concrete API names ('createWorkbook()', 'loadWorkbook(inputPath)'), matching the 'fully executable; copy-paste ready' top anchor.

5 / 5

Workflow Clarity

A clear three-stage sequence (Understand → Execute → Review → Deliver) carries explicit validation checkpoints ('Review the workbook itself, not a hand-written pass status'), an evaluate step, and a feedback loop ('If evidence reveals a problem, revise the builder and review the new candidate'), matching the top anchor with validation and error-recovery loops.

5 / 5

Progressive Disclosure

SKILL.md is a concise overview with seven clearly signaled one-level-deep references (all verified to exist under references/) in a dedicated 'Load references only when needed' section, with detailed API/formatting/chart content appropriately split out, matching the 'clear overview with well-signaled one-level-deep references' top anchor.

Description

100%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 specific, trigger-rich, complete, and well-bounded: it states concrete capabilities, natural use-when triggers with file extensions, and an explicit do-not-use boundary. It is a strong, low-conflict skill description.

DimensionReasoningScore

Specificity

The description lists six concrete verbs ('Create, edit, inspect, transform, render, and verify') plus a comprehensive task list including 'formatting, formulas, charts, data consolidation, source-based calculations, numeric reconciliation, legacy conversion, and visual QA', matching the 'multiple specific concrete actions; comprehensive coverage' anchor.

5 / 5

Completeness

It explicitly answers 'what' (six verbs and a concrete task list) and 'when' ('Use for spreadsheet generation, formatting, formulas, charts...'), and adds an explicit negative-boundary clause ('Do not use for live control of Microsoft Excel or macro-enabled workbook editing'), matching the anchor that requires concrete trigger phrases for both.

5 / 5

Trigger Term Quality

It covers natural terms users would say — 'spreadsheets', 'formatting', 'formulas', 'charts' — together with the file extensions XLSX, XLS, CSV, and TSV, giving comprehensive coverage including synonyms and extensions as the top anchor requires.

5 / 5

Distinctiveness Conflict Risk

It carves a clear niche ('standalone XLSX, XLS, CSV, and TSV files') and explicitly excludes the most likely conflict ('Do not use for live control of Microsoft Excel or macro-enabled workbook editing'), yielding minimal conflict risk as the top anchor describes.
