xlsx

Create, edit, analyze, or convert Excel spreadsheets (.xlsx, .xlsm, .xltx) where the workbook file is the primary deliverable. Use for formulas, formatting, financial models, multi-sheet workbooks, and tabular cleanup exported to Excel. Also applies to .csv/.tsv when the user wants spreadsheet output. Do NOT use for Word documents, HTML reports, standalone Python scripts, database pipelines, or Google Sheets API work.

Quality

Content

100%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A lean, highly actionable skill body: every line is a concrete gotcha or command, the recalc step provides an explicit validate-fix-retry feedback loop, and the bundle is referenced one level deep with clear sectioning. It assumes Claude's competence and surfaces only what is non-obvious.

DimensionReasoningScore

Conciseness

The body is dense with non-obvious, task-critical gotchas (openpyxl two-load behavior, _xlfn prefixes, external-link stripping) and never pads with concepts Claude already knows, so every token earns its place; it is not the 'mostly efficient but could be tightened' of a 2.

3 / 3

Actionability

Guidance is copy-paste ready — `python scripts/recalc.py output.xlsx [timeout_seconds]`, `sheet['B10'] = '=SUM(B2:B9)'`, and exact format strings like `$#,##0;($#,##0);-` — giving fully executable commands and examples rather than pseudocode.

3 / 3

Workflow Clarity

The recalc loop is an explicit validation checkpoint with a feedback loop: run recalc, inspect `status`/`error_summary`, fix named cells, re-run, and never ship while `errors_found` — with the exit-code trap called out — which matches the 'clear sequence with explicit validation steps' anchor.

3 / 3

Progressive Disclosure

The body is a well-sectioned overview (Requirements, Recalculate, Formula choice, Gotchas, Financial models, Dependencies) that references the real script bundle (`scripts/recalc.py`, `scripts/office/soffice.py`, verified present) one level deep with a clear 'script paths relative to this skill's directory' signal, keeping guidance inline and executable code in scripts.

Description

100%Weight 40%Scale 1-3

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 tight, trigger-rich description that answers both what and when, names concrete actions, and uses an explicit exclusion list to avoid overlap with sibling skills. No vague fluff or over-claims.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions — 'Create, edit, analyze, or convert Excel spreadsheets' — plus specific deliverable types (.xlsx, .xlsm, .xltx), matching the 'lists multiple specific concrete actions' anchor rather than the partial coverage of a 2.

3 / 3

Completeness

It states what ('Create, edit, analyze, or convert...') and when via an explicit 'Use for...' clause plus 'Also applies to .csv/.tsv when the user wants spreadsheet output', so both halves are explicit rather than just implied (which would cap it at 2).

3 / 3

Trigger Term Quality

It covers natural terms users actually say — 'Excel spreadsheets', 'formulas', 'formatting', 'financial models', 'multi-sheet workbooks', '.xlsx', '.xlsm', '.xltx', '.csv/.tsv' — giving broad coverage of common variations rather than only jargon.

3 / 3

Distinctiveness Conflict Risk

The explicit 'Do NOT use for Word documents, HTML reports, standalone Python scripts, database pipelines, or Google Sheets API work' carves a clear niche with negative triggers, making conflict with adjacent skills unlikely.
