Kiro's upstream system prompt overrides all user-provided system
prompts and returns "I can't discuss that" for identity questions.
This pre-flight interceptor detects identity questions (Chinese and
English patterns) in the last user message and returns a Claude-style
response directly, bypassing Kiro entirely.
Response language matches the question language; model name reflects
the requested model (Claude Opus 4.7, Claude Sonnet 4.5, etc.).
Applied to both /v1/messages (Claude) and /v1/chat/completions (OpenAI).
