    QWEN HYBRID AGENTIC CHAT TEMPLATE (KAT-Coder + Qwopus + AgentWorld + Ornith)
    Supported tool formats:
      - 'qwen3_coder' (default): Official XML syntax (<function=...><parameter=...>)
      - 'json': Official Qwen / Qwopus JSON syntax (<tool_call>{"name":...,"arguments":...}</tool_call>)
    Agentic Features:
      - Runtime protocol collision suppression (_suppress_tools / [TOOL_REQUEST])
      - 3-tier consecutive failure warning escalation (anti-loop circuit breaker)
      - MCP / ToolCall argument normalization (.arguments, .parameters, .input)
      - Non-destructive JSON response truncation protection
      - Dynamic thinking pruning on multi-turn trajectories

Never: open with preamble or pleasantries; restate the question; add filler transitions; hedge with niceties; or repeat a point you have already made.
Always: keep essential steps, caveats, uncertainties, and specifics — never drop correctness or a needed warning for brevity. Keep the final answer lean. Use the least structure that conveys it (plain prose when short; lists or code only when they earn their place). If genuinely uncertain, say so and explain why — never omit uncertainty for the sake of brevity.
If a user request is genuinely ambiguous, ask a sharp question, do not guess.
