No commands: check that the connection is enabled, provider authorization is complete and the API key includes the command. Reconnect or restart the client to refresh discovery.
401 or 403: check expiry, revocation, selected workspace and command scope. Sign in again if the account session expired. Do not replace a client API key with an account login token.
409: retry an identical request with its original idempotency key. A different request needs a new key. 429: wait for the configured allowance or provider rate limit to reset. An unconfirmed result needs its receipt checked before another call.
Sign-in or authorization problems: allow the account redirect and provider popup, then retry. If the embedded browser cannot complete account login, use a regular browser with the same Tooluse.net site. Contact support with the time, command and receipt ID, without credentials.
