Error message

extensions.add_name_required

What it means

createLibraryItem validates the new library item (skill/command/agent/mcp/plugin) before talking to the Den API. A missing name is the first check; the localized validation message t('extensions.add_name_required') is thrown as the Error message so UI code can match on the i18n key string.

Solutions

  1. Set a non-empty name on the input before calling createLibraryItem.
  2. Validate in the form/UI layer (disable submit until name.trim() is non-empty) so the API-layer error never fires.
  3. If the error appears despite a filled field, check for stray whitespace-only input or a binding bug where input.name is undefined at call time.

Example fix

// before
await createLibraryItem('skill', { name: '', description: '...', instructions: '...' });
// after
const name = form.name.trim();
if (!name) { showFieldError('name', t('extensions.add_name_required')); return; }
await createLibraryItem('skill', { ...form, name });
Defensive patterns

Strategy: validation

Validate before calling

const name = input.name.trim();
if (!name) { showFieldError('name', t('extensions.add_name_required')); return; }

Try / catch

try {
  await createLibraryItem(kind, input);
} catch (e) {
  if (e instanceof Error && e.message === t('extensions.add_name_required')) {
    showFieldError('name', e.message);
  } else throw e;
}

Prevention

When it happens

Trigger: Calling createLibraryItem(kind, input) with input.name empty or whitespace-only ('', ' ') — the trim() leaves an empty string.

Common situations: Submitting the 'Add to library' form without typing a name; programmatically building CreateLibraryItemInput and forgetting the name field; copying an input object where name was nulled by a form reset.
