Failed to load.

Error message

Failed to load.

What it means

Set as the card's <pre> text in _toggleBuiltinExpand (static/js/skills.js:552) when GET /api/skills/builtin/{name} fails; unlike other handlers the HTTP status is swallowed entirely — the user sees only 'Failed to load.'. The flag card._loaded stays false, so collapsing and re-expanding retries the fetch.

Solutions

1. Run the GET by hand (devtools Network tab) to recover the hidden status: 404 → the builtin no longer exists in this server version, reload the page to re-fetch the builtin list; 401 → re-login.
2. Ensure the frontend and backend are the same version (hard-refresh to bust a stale JS bundle).
3. Collapse and re-expand the card to retry, since _loaded remains false on failure.
4. Improve the message to include the status so users can self-diagnose.

Example fix

// before
} catch (e) {
  pre.textContent = 'Failed to load.';
}
// after
} catch (e) {
  pre.textContent = `Failed to load (HTTP ${e.message.replace('HTTP ', '')}). Click to retry.`;
}

if (!name || card._loaded) return; // skip fetch when already loaded or name unknown

try { const res = await fetch(`${API}/api/skills/builtin/${encodeURIComponent(name)}`); if (!res.ok) throw new Error(`HTTP ${res.status}`); const data = await res.json(); pre.textContent = data.text || '(empty)'; card._loaded = true; } catch (e) { pre.textContent = `Failed to load (${e.message}). Collapse and re-expand to retry.`; }

When it happens

Trigger: Expanding a built-in skill card in the skills browser: GET /api/skills/builtin/{name}. Fails on 404 (built-in renamed/removed in a server version change), 401 (expired session), or 500 (read error on the packaged builtin file).

Common situations: Frontend bundle (static/js) newer or older than the server's built-in skill set after a partial upgrade; auth cookie expired while the page was open; builtin asset missing from a container image.
