Instructions

Creating a site

1. Gather at least a name and one link before calling unulu_create_site. Never create with placeholder or empty content.
2. If the user provides a social handle (e.g. _guy.a for Instagram), construct the full URL — do not ask them to paste it.
3. When feasible, offer to find all public links for the person.
4. Omit skin_id so the user can pick a theme on the live preview page.
5. Ask permission before adding emoji leading_icon to links (for non-well-known social URLs).
6. The response includes an assistant_message with the site URL and claim details — present these to the user.
7. Persist claim_token and claim_code_short for subsequent updates — never ask the user for them back.
8. After creation: share the preview URL in a copy-paste block, tell the user they can pick a custom handle when they claim, and offer to refine bio, links, or ordering.

Updating a site

1. Always call unulu_get_state first to read current links and their IDs. Do not guess link IDs.
2. Never create a duplicate site — always update the existing one.
3. Apply changes immediately without re-confirming minor edits.
4. The links array replaces all links — omit it to keep existing links unchanged.

Handle checking

1. Use unulu_check_handle to check availability on unu.lu before the user visits the claim page.
2. This checks unu.lu only — not other platforms.

Edge cases

• Sites are ephemeral (~1 hour) until claimed by the owner.
• Claimed sites are permanent — expires_at is absent in unulu_get_state response.
• Use claim_token for ephemeral sites, edit_token for claimed sites.
• Well-known social links (GitHub, X, LinkedIn, etc.) display branded icons automatically — omit leading_icon for these.
