Claude Code Auto Mode with DeepSeek, GLM or Kimi: What Each "temporarily unavailable" Reason Means and When Retrying Is Pointless (Fault-Injection Test)
On a third-party model, Claude Code auto mode sends one extra classifier request per side-effecting action, from your session model to the same backend: a 132,470-character system prompt, about 29.7K input tokens per check. When it fails, you see "xxx is temporarily unavailable, so auto mode cannot determine the safety of Bash". We injected faults and recorded each message: 500 (server error), 429 (rate-limited), 529 (overloaded) and connection resets (connection failed) are retried 5 times; no reply in 60 s gives (timed out). **No parentheses means a 4xx rejection: tried once, and retrying never helps.** A reply with no verdict gives "could not evaluate"; three in a row bring back manual approval. CLAUDE_CODE_AUTO_MODE_MODEL has no effect. Claude Code 2.1.285, real DeepSeek v4-pro and MiMo v2.5 backends.

Claude Code "bash denied by auto mode": Why It Blocks, "could not evaluate" and "unavailable for this model" Tested
In auto mode, a blocked Bash call usually shows one of three messages: denied by auto mode, Auto mode could not evaluate this action, or auto mode unavailable for this model. I ran 40-odd real sessions on Claude Code 2.1.280. denied means the classifier judged the action out of scope, most often [Code from External]: it would run external code you never named. Retrying won't help. Name the source in your prompt, or declare it trusted in autoMode.environment in user-level settings. could not evaluate means the classifier returned no usable verdict. unavailable for this model means the model is older than claude-opus-4-6; under claude -p it is silently downgraded, with only a WARN line in the debug log. In 2.1.280 the verdict is computed server-side and returned with the main response. Behind a relay gateway that only admits Claude Code clients, the local fallback classifier request gets a 503, which is a reliable cause of "temporarily unavailable (server error)".
