Use when asking about core node types, category conventions, tensor formats, ensuring custom nodes are compatible with ComfyUI's core ecosystem, IMAGE/MASK/LATENT type formats, or how built-in nodes work. Triggers on "what format is IMAGE", "compatible with core nodes", "standard type", "기본 노드 호환", "타입 포맷".

Use when asking about list processing, INPUT_IS_LIST, OUTPUT_IS_LIST, batch processing, rebatching, handling multiple items in custom nodes, processing multiple images at once, or receiving/returning lists from a node. Triggers on "handle multiple inputs", "batch images", "list of tensors", "여러 이미지 처리", "배치 입력".

Use when user encounters errors in ComfyUI custom nodes, asks about debugging, needs to analyze stack traces, troubleshoot execution failures, fix type errors, or diagnose tensor shape mismatches.

Use when asking about hidden inputs (UNIQUE_ID, PROMPT, EXTRA_PNGINFO, DYNPROMPT), flexible inputs, wildcards, dynamic input handling, accessing current prompt data inside a node, passing metadata between nodes, or accepting any input type. Triggers on "get prompt info", "access workflow data", "wildcard input", "any type input", "노드에서 프롬프트 접근", "숨은 입력".

Use when asking about lazy evaluation, conditional execution, ExecutionBlocker, check_lazy_status, skipping unused inputs, preventing unnecessary computation, or "only run if needed". Triggers on "skip input", "conditional node", "don't process unless", "입력 건너뛰기", "조건부 실행".
