No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends
Thinking disable settings ignored for Haiku 5.5. Haiku 5.5 still returns thinking blocks with --thinking disabled, the SDK thinking option, or CLAUDE_CODE_DISABLE_THINKING=1; the request has no thinking field.
