Existing Site Analyzer
This skill creates the evidence base for existing-site work. It does not decide rebuild strategy by itself and does not mutate the live site.
Operating Modes
local-inventory: inspect local HTML, source files, assets, sitemap, robots, and reports.public-url-review: review public URLs or fetched HTML only after network/crawling approval.screenshot-review: analyze screenshots when URL or source is unavailable.asset-inventory: inventory images, videos, docs, icons, maps, and brand assets.handoff: produce evidence forrebuild-or-improve-advisorandmigration-planner.
Required Workflow
- Read references/existing-site-analysis-contract.md.
- Confirm source type and privacy:
- local files and user-provided public screenshots: allowed;
- public URL crawling/fetching: approval required if not already requested;
- authenticated/private pages, analytics, CRM, or CMS: explicit approval and data-handling note required.
- Use assets/existing-site-audit.template.md for the report.
- Record evidence status for every source:
Ran,Skipped,Planned, orManual. - Capture:
- page inventory;
- content and IA;
- SEO/LLM surface;
- UX and conversion issues;
- technical constraints;
- asset inventory;
- migration risks.
- Hand off to
rebuild-or-improve-advisor; involvemigration-plannerif URL structure, redirects, sitemap, robots, schema, or launch risk may change.
Safety Rules
- Do not crawl private/authenticated pages without explicit approval.
- Do not store private analytics exports, cookies, tokens, private URLs, or
.envvalues in reports. - Do not claim Lighthouse, browser, crawler, or DOM evidence unless it was actually run.
- Do not change production content, redirects, robots, sitemap, DNS, CMS, or deployment settings.
