Names the domain (Google Sheets, Google Docs) and describes two actions (read data, create report), but lacks detail on what 'formatted' means or what kinds of reports are generated.

Describes what the skill does but has no 'Use when...' clause or equivalent explicit trigger guidance, which per the rubric caps completeness at 2, and the 'what' itself is also thin—so this lands at 1.

Includes 'Google Sheet' and 'Google Docs report' which are natural terms, but misses common variations like 'spreadsheet', 'Sheets', 'Docs', 'generate report from data', or file-type references.

The combination of Google Sheets input and Google Docs output is somewhat distinctive, but 'read data' and 'create report' are generic enough to overlap with other reporting or data-processing skills.

The skill is lean and efficient. It assumes Claude knows what Google Sheets and Docs are, provides no unnecessary explanation, and every line serves a purpose.

The commands are concrete and copy-paste ready, but the example uses hardcoded placeholder data (DOC_ID, SHEET_ID) without showing how to capture and pass the document ID from step 2 into step 3. The report content is also hardcoded rather than showing how to transform the sheet data into the report text.

The steps are clearly sequenced, but there are no validation checkpoints—no verification that the sheet read returned data, no check that the document was created successfully before writing, and no confirmation that sharing succeeded. For a multi-step workflow involving external API calls, this is a gap.

For a short recipe-style skill, the structure is appropriate: a prerequisite note pointing to dependent skills, a clear steps section, and no unnecessary nesting. The references to prerequisite skills are one level deep and clearly signaled.
