100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, executable skill body: tight code, an explicit validation checkpoint and error-recovery feedback loop, and a real one-level-deep reference that keeps the overview lean. It meets the score-3 anchor on all four dimensions.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body assumes Claude's competence — it does not teach what a PDF is or how libraries work — and every section earns its place; the opening two-sentence rationale ('PDFs are binary documents ... Direct binary diff is useless') is skill-specific framing rather than generic padding. Minor duplication between the 'How to use' summary and the expanded Step 1–6 sections is the only tightening opportunity, but it serves navigation rather than verbosity. | 3 / 3 |
Actionability | Every step ships fully executable code or commands — real `pdf2image`/`Pillow` imports, concrete `pdftocairo -png -r 150` invocations, exact thresholds (~0.005), and a copy-paste-ready `test_invoice_pdf_matches_baseline` test — with no pseudocode gaps. | 3 / 3 |
Workflow Clarity | The six-step sequence is clearly ordered with an explicit validation checkpoint (assert diff ratio < threshold), a real feedback loop in the worked example (diff fails → `pdfinfo -list-embedded-fonts` distinguishes real layout shift from font substitution → fix → re-run → refresh baseline), and an anti-patterns table that functions as a checklist for the batch/destructive baseline-update operation. | 3 / 3 |
Progressive Disclosure | SKILL.md is an overview that pushes metadata-stripping and font-substitution detail into a single one-level-deep, well-signaled reference (linked in both Step 6 and the 'Deterministic rendering' section); the referenced file references/deterministic-rendering.md exists, so navigation resolves cleanly. | 3 / 3 |
