What causes "Execution failed after all attempts" in ruvnet/ruflo?

Find the actual cause first: the last attempt's error was captured before the final throw — enable logging on the per-attempt error path or attach a debugger instead of trusting this generic message

Execution failed after all attempts

Error message

Execution failed after all attempts

What it means

Thrown at the end of ProviderAdapter's retry loop: every attempt (governed by options.retry — backoffMs, backoffMultiplier, attempt count) failed and the loop exhausted. The real per-attempt error is captured inside the loop, but the final throw discards it, so this generic message alone never reveals the root cause.

Solutions

Find the actual cause first: the last attempt's error was captured before the final throw — enable logging on the per-attempt error path or attach a debugger instead of trusting this generic message
If the failure is deterministic (auth, validation, 4xx), fix the root cause rather than adding retries
For genuinely transient faults (timeouts, 503), raise retry attempts and lengthen backoff so the window outlasts the outage
Verify provider credentials and endpoint reachability with one minimal direct call

Example fix

// before
const result = await adapter.execute(task, {
  retry: { attempts: 2, backoffMs: 100, backoffMultiplier: 2 }, // gives up inside a short 503 blip
});

// after
const result = await adapter.execute(task, {
  retry: { attempts: 5, backoffMs: 500, backoffMultiplier: 2 }, // window outlasts transient provider errors
});

Defensive patterns

Strategy: retry

Validate before calling

// Smoke-test the provider with a cheap probe before submitting real work
const healthy = await adapter.execute(minimalProbeTask, { retry: { attempts: 1 } })
  .then(() => true, () => false);
if (!healthy) {
  // route elsewhere or alert instead of burning a full retry budget
}

Try / catch

try {
  const result = await adapter.execute(task, retryOptions);
} catch (e) {
  if (e instanceof Error && e.message === 'Execution failed after all attempts') {
    // all retries exhausted: back off hard, circuit-break the provider, never tight-loop
  }
  throw e;
}

Prevention

Classify errors before retrying — retry only transient classes (timeout, 5xx, 429)
Wrap execution so the last underlying error is preserved in your own logs
Add a circuit breaker so a downed provider doesn't repeatedly consume retry budgets

When it happens

Trigger: Executing a task against a provider where the underlying call fails on attempt 1 through the last attempt, including the final post-backoff retry — e.g. persistent HTTP 401/403, an unreachable endpoint, or a payload the provider rejects every time.

Common situations: Invalid or expired provider credentials (deterministic failures that retries cannot fix), a network/DNS outage lasting longer than the total backoff window, a wrong base URL, or a malformed request that always yields a 4xx.
