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.
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for brand voice, key pages, and Section 12 (Visual Identity).
Identify:
| Element | Purpose |
|---|---|
| Site navigation | Header/footer so users know they're still on your site |
| Search | Help users find what they need |
| Popular pages | Links to homepage, features, pricing, blog |
| Similar URLs | Suggest corrections for common typos |
| Avoid auto-redirect | Unless confident of user intent |
