Failed to send prompt

Error message

Failed to send prompt

What it means

Thrown when `terminal.send` (the prompt text, enter:true) returns a failure during PR AI triage launch - step two after the terminal was created. The host's error.message is preferred; the literal is the fallback.

Solutions

1. Retry the whole launch (create + send) after reconnecting.
2. Check the terminal still exists.
3. Inspect host PTY logs.
4. Ensure no host-side input lock is active.

Example fix

// before
if (!sent.ok) {
  throw new Error(sent.error?.message || 'Failed to send prompt')
}
// after
if (!sent.ok) {
  throw new RpcMethodError('terminal.send', sent.error)
}

function isRpcFailure(r: RpcResponse): r is RpcFailure {
  return r.ok === false
}

try {
  await createTerminalAndSendPrompt(client, worktreeId, prompt)
} catch (err) {
  setTriageError(err instanceof Error ? err.message : 'Could not deliver the AI prompt')
}

When it happens

Trigger: Terminal handle became invalid between create and send (closed/disposed), host PTY error, or a transport failure on the one-shot. The prompt is plain text so content-based rejection is unlikely.

Common situations: Terminal closed on the host between the two RPCs; relay hiccup; host PTY spawn failure; a host-side permission prompt blocking the send.
