Quality

Content

87%

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

The content is concise and highly actionable with executable create/edit examples and clear format-selection guidance, organized as a tidy self-contained skill. The main gap is the absence of explicit validation or error-recovery checkpoints in the create/edit workflow.

Suggestions

Add an explicit validation step after edit operations (e.g., how to confirm cells were written correctly or how to detect/handle a failed tool call) so create/edit has a validate→fix→retry loop.

Include a short error-recovery note for common failures (unknown file_id, invalid sheet/cell reference) to give the workflow a checkpoint rather than only a happy path.

Dimension	Reasoning	Score
Conciseness	The body is lean and efficient — direct "Use ODS when..." / "Use XLSX only when..." guidance with no padding and no explanation of concepts Claude already knows; every line is actionable.	3 / 3
Actionability	Provides fully executable JSON tool-call examples for create and edit with real tool_args (action, kind, format, content, sheet-scoped cells) plus concrete rules (rows vs append_rows vs set_cells, create_chart), matching copy-paste-ready guidance.	3 / 3
Workflow Clarity	Create and edit steps are sequenced and accompanied by decision rules, but there is no explicit validation checkpoint or feedback loop (e.g., verify cells written, handle errors/retry) for edit operations, which caps clarity at 2.	2 / 3
Progressive Disclosure	The skill is self-contained and under ~50 lines with no bundle files, organized into clear sections (# Calc Spreadsheets, ## Workflow, practical rules), which meets the simple-skill bar for full marks.	3 / 3

Description

100%

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, well-triggered, and distinctive, explicitly stating both what it does and when to use it with a sharp conditional that reduces conflict risk. It is concise with no fluff or over-claims.

Dimension	Reasoning	Score
Specificity	Names concrete actions ("creating, opening, or editing") and concrete formats ("LibreOffice Calc ODS spreadsheets", "XLSX workbooks"), matching the multiple-specific-actions anchor; not merely a domain mention.	3 / 3
Completeness	Opens with an explicit "Use when..." clause and states what the skill does, clearly answering both what and when rather than leaving the trigger implied.	3 / 3
Trigger Term Quality	Covers natural user terms — Calc, ODS spreadsheets, XLSX, Excel, spreadsheets — giving good coverage of what a user would actually say, beyond a single keyword.	3 / 3
Distinctiveness Conflict Risk	The LibreOffice Calc/ODS niche plus the conditional "XLSX only when Excel compatibility is explicitly required" makes it clearly distinct and unlikely to trigger for the wrong skill.	3 / 3
