**/*

**/*: Keep changes small, direct, and limited to the narrowest necessary code path and smallest number of files.
Prefer practical fixes, minimal dependencies, and existing repository patterns; remove obsolete, dead, unreachable, or unused code.
Preserve existing APIs, node names, model-loading behavior, file layout, and workflow compatibility unless replacement is explicitly intended.
Core ComfyUI must not add outbound internet requests, telemetry, tracking, reporting, remote configuration, or background network activity. User-authorized model downloads are limited to the requested artifact and must exclude telemetry and unrelated metadata.

**/*.py

📄 CodeRabbit inference engine (AGENTS.md)

**/*.py: Keep state and capability flags on the object that owns the behavior. Prefer explicit parent-owned attributes over probing child objects with getattr; use child checks only when the child owns the delegated behavior.
Preserve shared method signatures, argument order, return shapes, side effects, and error behavior unless every affected caller and interface is intentionally updated.
Do not add unused compatibility parameters, flags, attributes, constructor options, or model-specific options to shared helpers; keep one-off behavior at the integration boundary.
Normalize third-party return conventions at integration boundaries so core code receives the expected type and shape; avoid undocumented caller-side unwrapping.
Do not add torch.no_grad, torch.inference_mode, or inference-mode wrappers. Do not add model freeze/unfreeze toggles; only disable globally enabled inference mode when a training path requires gradients.
Remove inference-only training behavior such as dropout while preserving checkpoint and state-dict compatibility; use nn.Identity when deleting a module would alter keys or ordering.
Keep imports at module scope except established optional-backend probes or imports required to avoid cycles; avoid unnecessary try/except blocks and use specific exceptions with useful fallbacks.
Do not add workarounds for unsupported library versions, especially PyTorch exception-and-float-cast retries, unless a comment names the exact versions still requiring them.
Let unsupported model formats, invalid quantization metadata, and bad states fail with clear errors instead of silently degrading output.
Match local style, keep comments sparse and useful, and remove comments that merely restate obvious code.
Treat dtype, device placement, VRAM use, and offloading as correctness concerns across CPU, CUDA, ROCm, MPS, DirectML, XPU, NPU, and low-VRAM environments.
Prefer existing ComfyUI and Comfy Kitchen operations, quantization helpers, cast/offload helpe...

Flag PR changes that violate AGENTS.md even when the code is otherwise functional.
In particular, enforce architecture boundaries, dtype/device/memory rules,

📝 Walkthrough

Walkthrough

Meshy nodes now support meshy-7, meshy-6, texture resolutions, and credit-based pricing. Text-to-model and image-to-model nodes add ultra_mode validation and API support. Refine and retexture requests pass texture resolution. The texture node uses MESHY_TASK_ID. A multi-view texture node uploads reference images, submits retexture requests, polls completion, and downloads GLB or FBX outputs. Rigging and animation prices were updated.

Merge Risk: 🟡 Moderate · up to 7c41b

This change may remove a Meshy style value used by existing workflows, potentially causing those workflows to fail or behave differently. Merge readiness remains moderate until compatibility is preserved or the breaking change is explicitly accepted.

In `@comfy_api_nodes/nodes_meshy.py`:
- Line 40: Update the style options in MeshyTextToModelNode to retain the
existing sculpture value alongside realistic, preserving validation and
compatibility for previously saved workflows.
- Around line 121-122: Update the ultra_mode validation error messages in the
model guards to state that both meshy-7 and latest support ultra_mode, matching
the values permitted by the checks.
- Around line 965-967: Update the multiview upload flow in the node method
around upload_images_to_comfyapi to count flattened reference images, reject
totals below one or above four, and pass max_images=4 to the upload helper. Use
the existing local dynamic-input validation pattern for the error handling.
