579In an interactive session, a dim `Not run · auto mode's check had no usable answer` row appears under the tool call instead of this message. Press `Ctrl+O` to read the message in the [transcript viewer](/docs/en/interactive-mode#transcript-viewer). The denials under [The server returned no safety verdict](#the-server-returned-no-safety-verdict) show the same row. Before v2.1.296, the message appeared under the call as a red error.

578581When Claude Code can determine the failure category, it names the category in parentheses after `temporarily unavailable`, for example `<model> is temporarily unavailable (rate-limited), so auto mode cannot determine the safety of <tool> right now`. The categories are `(rate-limited)`, `(overloaded)`, `(server error)`, `(timed out)`, and `(connection failed)`. If `(timed out)` or `(connection failed)` repeats, check your connection; see [Unable to connect to API](#unable-to-connect-to-api). Before v2.1.229, the message never named a category and read `Wait briefly and then try this action again`.
579582
580583When no category fits, the message appears with no category in parentheses; more than one failure produces that form. On [Amazon Bedrock](/docs/en/amazon-bedrock), including the [Mantle endpoint](/docs/en/amazon-bedrock#use-the-mantle-endpoint), it also appears when your AWS account can't invoke the model named in the message, and that failure repeats on every retry until your account is granted access to the model.

27722775You passed [`--append-subagent-system-prompt`](/docs/en/cli-reference#cli-flags) together with `--append-subagent-system-prompt-file` in one `claude` invocation, so `claude` exits with code 1 instead of starting the session:
27732776
27742777```text theme={null}
2775Error: Cannot use both --append-subagent-system-prompt and --append-subagent-system-prompt-file. Please use only one.

2777
2778Before v2.1.283, `claude` exited the same way when you passed `--system-prompt` with `--system-prompt-file`, or `--append-system-prompt` with `--append-system-prompt-file`, because those pairs conflicted instead of [combining](/docs/en/cli-reference#system-prompt-flags). On those versions the message names the pair you combined.
2779
2780**What to do:**
2781
2782* Keep one form of the flag and drop the other. To combine a fixed prompt file with per-run text, merge the text into the file before launching instead of passing both flags
