One of 8 test cases the skill fixed. Same model, same prompt, with and without the skill.
During our technical crawl, we detected 301 redirect chains with 4+ hops and hundreds of internal broken 404 links draining crawl budget. Which specific domain sub-skill should be assigned to investigate and remediate these crawlability blockers?
| Checked | Without skill | With skill |
|---|---|---|
| Maps 301 redirect chain and broken link remediation to the site-crawlability skill. | Passed | Passed |
| Assigns crawlability blockers to Phase 1 Technical audit. | Missed | Passed |
The instructions your model reads when the skill loads.
Guides end-to-end SEO audit: technical foundation, on-page, content, and off-page. Execute in order—technical blockers prevent indexing; on-page limits rankings; content and off-page build authority. Use when auditing an existing site or planning fixes.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
