AustinMroz 86b1e1a965 Fix descriptions on core blueprints (#12220)
Core blueprints were storing the description under a different key than
expected, which resulted in them displaying a placeholder description.
When initializing the description for a subgraph, this alternative field
is also checked.

ComfyUI DevTools

This directory contains development tools and test utilities for ComfyUI, previously maintained as a separate repository at https://github.com/Comfy-Org/ComfyUI_devtools.

Contents

  • __init__.py - Server endpoints for development tools (/api/devtools/*)
  • dev_nodes.py - Development and testing nodes for ComfyUI
  • fake_model.safetensors - Test fixture for model loading tests

Purpose

These tools provide:

  • Test endpoints for browser automation
  • Development nodes for testing various UI features
  • Mock data for consistent testing environments

Usage

During CI/CD, these files are automatically copied to the ComfyUI custom_nodes directory. For local development, copy these files to your ComfyUI installation:

cp -r tools/devtools/* /path/to/your/ComfyUI/custom_nodes/ComfyUI_devtools/

Migration

This directory was created as part of issue #4683 to merge the ComfyUI_devtools repository into the main frontend repository, eliminating the need for separate versioning and simplifying the development workflow.
