wigolo-diff

Compare two versions of a page and see exactly what changed — a live URL against its cached copy, two URLs, or two markdown blobs. Section-level hunks, word- or line-level granularity, or a summary of counts. Use when the user says "what changed", "diff these", "compare this page to last time", "show me the changes", "did this doc update", or wants a changelog between two versions of the same content.

Quality

Content

100%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

An exemplary compact skill body: executable examples for every common case, a precise parameter table, explicit anti-patterns and routing guidance to sibling skills, and no padding. Nothing material is missing or misplaced.

DimensionReasoningScore

Conciseness

The ~59-line body is lean with zero concept explanations: Quick Reference payloads, a tight parameter table, output shapes, routing, and See Also each earn their place, assuming Claude's competence throughout.

5 / 5

Actionability

Five copy-paste-ready JSON payloads cover the common invocation modes (live-vs-cache, two URLs, two blobs, hunks+word, summary), and the parameter table specifies types, defaults, and when-to-use; the only uncovered key (`content_hash`) is a rare path.

5 / 5

Workflow Clarity

This is a simple single-purpose skill whose one action — invoking the diff with the right parameters — is unambiguous via the Quick Reference and Parameters table; it is a read-only comparison with no destructive or batch operations requiring validation checkpoints.

5 / 5

Progressive Disclosure

There are no bundle files and nothing that belongs in a separate file is inlined; the short body is well-organized into clearly headed sections, and the See Also links to sibling SKILL.md files are one level deep and clearly signaled.

Description

96%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: concrete, third-person capability statements paired with an explicit trigger clause full of natural user phrases. The only weakness is that a couple of bare trigger terms are not scoped to page/content diffs, leaving slight ambiguity against code-diff requests.

Suggestions

Scope the ambiguous trigger phrases toward page/content diffs (e.g., "diff these pages", "what changed on this page") to reduce overlap with code-diff or generic text-diff tooling.

DimensionReasoningScore

Specificity

"Compare two versions of a page", "a live URL against its cached copy, two URLs, or two markdown blobs", and "Section-level hunks, word- or line-level granularity, or a summary of counts" name multiple concrete actions covering inputs, output modes, and granularity in third-person voice, matching the comprehensive-coverage anchor rather than the minor-gaps anchor.

5 / 5

Completeness

It clearly answers what ("Compare two versions of a page... Section-level hunks, word- or line-level granularity, or a summary of counts") and explicitly when via a "Use when the user says..." clause with concrete trigger phrases — the exact top-anchor pattern.

5 / 5

Trigger Term Quality

Six quoted natural phrases ("what changed", "diff these", "compare this page to last time", "show me the changes", "did this doc update") plus "changelog" give comprehensive coverage of the words users would actually say for this need, including synonyms.

5 / 5

Distinctiveness Conflict Risk

The page-version drift-detection niche is mostly distinct, but generic trigger phrases like "diff these" and "what changed" could also fire on code-diff or generic text-diff requests, giving minor overlap risk with closely related diff tooling.
