comfyui-workflow-validator

comfyui-workflow-validator is a skill for Claude Code, Codex from IvanYangYangXi/artclaw_bridge. It costs 67 tokens per session (597 once invoked), scanned A, original, MIT.

A checker for ComfyUI workflows, which are sets of connected image-generation steps. It checks whether every node type used by a workflow is available in the current ComfyUI setup.

In plain words
What is it for?
Use it to validate a workflow file or workflow data, list available and missing nodes, and debug workflows that cannot be submitted.
Why use it?
It catches missing nodes before submission, making it easier to tell whether a workflow needs an additional node package or a replacement node.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

comfyui-workflow-validator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

ComfyUI Workflow 验证器

在提交 workflow 前验证所有节点是否可用。


快速使用

from comfyui_workflow_validator import validate_workflow

# 验证 workflow 文件
result = validate_workflow("/path/to/workflow.json")
if result["valid"]:
    print("✓ 所有节点都可用")
else:
    print(f"✗ 有 {len(result['missing_nodes'])} 个节点不可用")
    for node in result["missing_nodes"]:
        print(f"  - {node}")

完整示例

# 1. 加载 workflow
import json
with open("my_workflow.json", "r") as f:
    workflow = json.load(f)

# 2. 验证
from comfyui_workflow_validator import validate_workflow_dict
result = validate_workflow_dict(workflow)

# 3. 处理结果
if result["valid"]:
    print("✓ Workflow 验证通过,可以提交")
    # 提交 workflow
    client.submit_and_wait(workflow)
else:
    print("✗ Workflow 验证失败")
    print("\n缺失的节点:")
    for node in result["missing_nodes"]:
        print(f"  - {node}")
    print("\n建议:")
    print("  1. 安装缺失的节点包")
    print("  2. 或替换为等效的可用节点")

API 参考

validate_workflow(file_path: str) -> dict

    "nodes": list,           # 所有节点类型
    "available_nodes": list, # 可用节点
    "missing_nodes": list    # 缺失节点
}

validate_workflow_dict(workflow: dict) -> dict

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
