82%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 lean, actionable reference for the diffs tool with a clear mode-based workflow and no wasted tokens; its only gaps are the absence of a complete copy-paste example and explicit section headers.
Suggestions
Add one short concrete example showing a full diffs tool invocation (e.g. before/after with mode=file) and the subsequent message-tool delivery call to reach fully copy-paste-ready actionability.
Use lightweight section headers (e.g. '## Modes', '## Delivering the artifact') to make the already-organized structure explicit and improve navigability.
Optionally note how to verify the artifact was delivered (e.g. confirm the message tool returned a path) to add a light validation checkpoint for the delivery workflow.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence: each line delivers a concrete mode, parameter, or integration step with no padding or explanation of basic diff concepts, matching the 'every token earns its place' anchor. | 5 / 5 |
Actionability | Guidance is concrete and executable with specific tool names, modes (view/file/both), and parameters (fileFormat=png|pdf, fileQuality standard|hq|print), but lacks a fully copy-paste-ready example call, leaving minor gaps versus a 5. | 4 / 5 |
Workflow Clarity | A clear sequence exists (choose mode -> call diffs -> use details.viewerUrl with canvas or details.filePath with the message tool), and producing diffs is non-destructive so the validation cap does not apply; only minor implicit-checkpoint gaps keep it below 5. | 4 / 5 |
Progressive Disclosure | The skill is under 50 lines with no bundle files and no need for external references, and content is topically organized by mode, but it lacks explicit section headers that would make the structure fully navigable, fitting the 4 anchor. | 4 / 5 |
