One of 3 test cases the skill fixed. Same model, same prompt, with and without the skill.

Prompt

We have an existing React project using standard `react-helmet` for metadata management on our user profile page at https://example.com/user/profile. Fix a missing canonical tag on this page. Should we also rewrite the page to replace `react-helmet` with a different metadata framework?

What was checked, without and with the skill

Workflow

Identify pages with missing or incorrect metadata (titles, descriptions, canonical, OG tags)
Audit against the priority rules below — fix critical issues (duplicates, indexing) first
Ensure title, description, canonical, and og:url all agree with each other
Verify social cards render correctly on a real URL, not localhost
Keep diffs minimal and scoped to metadata only — do not refactor unrelated code

When to Use

Reference these guidelines when:

adding or changing page titles, descriptions, canonical, robots
implementing Open Graph or Twitter card metadata
setting favicons, app icons, manifest, theme-color
building shared SEO components or layout metadata defaults
adding structured data (JSON-LD)
changing locale, alternate languages, or canonical routing
shipping new pages, marketing pages, or shareable links

rule categories by priority

priority	category	impact
1	correctness and duplication	critical
2	title and description	high
3	canonical and indexing	high
4	social cards	high
5	icons and manifest	medium
6	structured data	medium
7	locale and alternates	low-medium
8	tool boundaries	critical

quick reference

1. correctness and duplication (critical)

define metadata in one place per page, avoid competing systems
do not emit duplicate title, description, canonical, or robots tags
metadata must be deterministic, no random or unstable values
escape and sanitize any user-generated or dynamic strings
every page must have safe defaults for title and description
