meta-llm

Error message

meta-llm: ${data.error?.message ?? res.status}

What it means

askSeraphina calls the configured meta-LLM HTTP endpoint (/v1/messages, Anthropic-style) and throws this error when the HTTP response is not ok or the JSON body contains an error field. The message carries the upstream provider's error message, or the HTTP status code when the body has no error.message. It is a wrapper that surfaces upstream meta-LLM API failures to the swarm-coordination caller.

Solutions

1. Verify the meta-LLM API key (x-api-key source) is set and valid for the endpoint
2. Check opts.metaLlmUrl / META_LLM() resolves to a correct, reachable Anthropic-compatible /v1/messages endpoint
3. Confirm the requested model name is supported by the endpoint
4. Retry on transient statuses (429/5xx) with backoff; inspect the upstream message in the error text for specifics

Example fix

// before
const res = await fetch(`${META_LLM(opts.metaLlmUrl)}/v1/messages`, { headers: { 'x-api-key': key, ... } });
// after — validate config before the call and retry transient failures
if (!key) throw new Error('meta-llm: missing API key (set the key env var)');
const res = await fetch(`${META_LLM(opts.metaLlmUrl)}/v1/messages`, { headers: { 'x-api-key': key, ... } });
if (res.status === 429 || res.status >= 500) { await sleep(backoff); return askSeraphina(opts, goal); }

const url = META_LLM(opts.metaLlmUrl);
if (!key) throw new Error('meta-llm API key missing');
try { new URL(`${url}/v1/messages`); } catch { throw new Error(`invalid metaLlmUrl: ${url}`); }

function hasUpstreamError(d: unknown): d is { error: { message?: string } } {
  return !!d && typeof d === 'object' && 'error' in d;
}

try {
  const answer = await askSeraphina(opts, goal);
} catch (e) {
  if (String(e.message).startsWith('meta-llm:')) {
    // inspect upstream message/status; retry transient (429/5xx) with backoff, else degrade
    return degradedSeraphina();
  }
  throw e;
}

When it happens

Trigger: fetch to META_LLM(opts.metaLlmUrl)/v1/messages returns a non-2xx status (401 bad x-api-key, 429 rate limit, 5xx provider outage), or returns 200 with a JSON body containing error.message (e.g. model not found, invalid request, overloaded).

Common situations: Missing or invalid META_LLM API key in the environment; wrong metaLlmUrl pointing at a non-Anthropic-compatible endpoint; unsupported model name sent in the request; provider-side rate limiting or overload during a 90s-timeout POST; proxy/firewall returning an HTML error page that fails JSON parsing upstream.

      'Ask Seraphina — the swarm queen / primary coordinator — for coordination guidance on a goal. She reads the live open-federation roster, claims board and recent messages from x.ruv.io, reasons through the cognitum meta-llm gateway (cost-governed; cognitum-auto by default, override with tier), and returns guidance plus structured proposals (Task/Claim/Handoff/Status) and risks. Use when you need to decide what the swarm should do next, who should take a resource, or how to resolve a claim conflict. Hand-assigning work from raw sync output is wrong because it ignores current claims and node liveness, which Seraphina checks first. Proposals are advisory; publish them explicitly with x_federation_publish (admin) if you agree.',
