76%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a strong, code-first skill: executable skeleton, concrete output contract, and a genuinely distinctive convention (every deck number bound programmatically to a named range in the source workbook). Its main weaknesses are the absence of any validation/verification step for the produced file and a monolithic single-file layout where the slide-structure checklist and binding details could live in references.
Suggestions
Add an explicit verification step after saving, e.g. re-open the .pptx with Presentation('./out/<name>.pptx') and assert slide count / placeholder content before reporting the path.
Move the 13-item pitch-deck slide checklist and/or the openpyxl named-range binding into a references/ file (e.g. references/slide-structure.md) and link to it from SKILL.md to slim the main file.
Trim the provenance/adaptation paragraphs and attribution section to a single line — they consume context without changing how the task is executed.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient: imperative conventions ("Never transcribe numbers from memory... open the workbook, read the named range"), compact code, and no explanation of concepts Claude already knows, matching anchor 4 'Efficient; minor instances of over-explanation that could be trimmed'. It falls short of anchor 5 because the provenance/adaptation paragraphs ("Adapted from Anthropic's...", the attribution section) and the 13-item slide checklist are context that does not earn its place for executing the task. | 4 / 5 |
Actionability | The content is fully executable: a pip install command, a complete copy-paste-ready skeleton covering title slide, table, and image embedding, a working openpyxl named-range resolver with docstring, and a concrete output contract ("Write to ./out/<name>.pptx... Return the relative path"). This matches anchor 5 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases'; it stays at 5 rather than 4 because the only unstated step (rendering the chart PNG) is explicitly delegated to rendering from the source workbook. | 5 / 5 |
Workflow Clarity | A rough sequence is implicit (install → load template → build slides → bind numbers → save to ./out), but steps are never enumerated and there is no validation checkpoint (e.g. re-opening or verifying the saved .pptx, or confirming the file exists before reporting the path), matching anchor 3 'Steps listed but validation gaps; sequence present but checkpoints missing or implicit'. It does not reach anchor 4 because the checkpoints are absent rather than merely minor, and the skill is ~160 lines so the simple-skill exception does not apply. | 3 / 5 |
Progressive Disclosure | No bundle files exist, and the body is well organized into clearly headed sections (Output contract, Setup, Core conventions, Skeleton, Binding, Checklist, When NOT to use), matching anchor 4 'Good structure; most content is appropriately placed; references mostly clear; minor organization gaps'. It is not anchor 5 because at ~160 lines the pitch-deck slide checklist and the workbook-binding detail are natural candidates for separate reference files, keeping SKILL.md as a leaner overview. | 4 / 5 |
