70%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured skill that clearly defines a workflow for reorganizing PR diffs into reviewer-optimized canvases. Its strengths are in workflow clarity and progressive disclosure, with appropriate references to the canvas SDK and policy files. Its main weakness is the lack of concrete, executable examples — a sample canvas output or a before/after example would significantly improve actionability.
Suggestions
Add a concrete example showing a small PR diff input and the expected canvas output structure (even abbreviated) to improve actionability.
Tighten the 'Be creative' section — the long enumeration of possible representations could be condensed to 1-2 sentences plus a short bullet list.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient and avoids explaining concepts Claude already knows, but some sections are slightly verbose — e.g., the 'Be creative' section and the 'Tone and content' section could be tightened. The enumeration of example representations in 'Be creative' is borderline padding. | 2 / 3 |
Actionability | The skill provides clear structural guidance (grouping strategy, callout tags, pseudocode approach) and a concrete command (`gh pr diff <pr>`), but lacks executable code examples, sample canvas output, or a concrete example of what a finished review canvas looks like. The guidance is specific but not copy-paste ready. | 2 / 3 |
Workflow Clarity | The workflow is clearly sequenced: check for PR link → gather diff → group changes → distill complex logic → trace tricky logic → add callouts → write commentary. The explicit gate ('If the user didn't provide a PR link, stop and ask') serves as a validation checkpoint. The ordering of sections maps directly to the execution order. | 3 / 3 |
Progressive Disclosure | The skill appropriately references external files (`SKILL.md` for canvas policy, `index.d.ts` for SDK surface) as one-level-deep references with clear paths. The content itself is well-organized into logical sections without being monolithic, and the skill stays at the right level of abstraction for an overview. | 3 / 3 |
