Significant attention impact (2.12% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟡unulu_create_site(name, bio, links, skin_id)

Create a link-in-bio site with a name, bio, and links. Returns a live URL on unu.lu that expires in 1 hour unless claimed. Do NOT call until you have at least a name and one link from the user — gather real content first, never create with placeholder or empty content. If the user provides a handle (e.g. '_guy.a' for Instagram), construct the full URL yourself — do not ask them to paste it. When feasible, offer to find all public links for the person. Before calling: tell the user they can choose a skin on the preview page for the overall aesthetic; ask permission before adding emoji leading_icons to decorate links (for not-well-known social URLs). The response includes an assistant_message with the site URL and claim details — present these to the user. Persist claim_token and claim_code_short for subsequent updates — never ask the user for them back in the same conversation. Never create a duplicate site; always update the existing one. After creation: tell the user they can pick a custom handle when they claim; share the preview URL in a copy-paste block; offer to refine bio, links, or ordering. Keep iteration fast — apply changes immediately, don't re-confirm minor edits.

🔴unulu_update_site(site_id, claim_token, claim_url, edit_token, name, ...)

Update an existing site. All fields are optional — only provided fields are changed. Links replace the entire array (omit to keep existing). Before updating, always call unulu_get_state first to read the current links and their ids — do not guess link ids. Authorization depends on site lifecycle: X-Claim-Token header for ephemeral (pre-claim) sites, X-Edit-Token header for claimed (post-claim) sites. If neither token is available and the site is claimed, use requestEditAccess to obtain an edit_token. If you created the site in this conversation, you already have the claim_token — use it directly. Returns the full updated site state. Keep iteration fast — apply changes immediately without re-confirming minor edits unless ambiguous. Accepts a site ID, a full URL (e.g. https://abc123.unu.lu), or a bare hostname (e.g. abc123.unu.lu).
