sd-node-capture

sd-node-capture is a skill for Claude Code, Codex from IvanYangYangXi/artclaw_bridge. It costs 106 tokens per session (1,476 once invoked), scanned A, original, MIT.

A Substance Designer tool that captures images of node outputs or texture channels for visual inspection.

In plain words
What is it for?
Use it to preview a selected node, capture multiple physically based rendering outputs, inspect intermediate stages, and review material quality.
Why use it?
It lets an AI see intermediate results and check whether a material graph is producing the intended textures.

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

sd-node-capture 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 9d 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.

SD 节点输出捕获与视觉分析

核心机制

save_preview — 预注入的截图函数

save_preview 是预注入到 exec 命名空间的辅助函数,自动完成:缩放 1/4 → jpg 压缩 → [IMAGE:] 标记输出。 AI 在 tool result 中可直接看到图片。

# 最简用法:传入节点,自动截图
node = graph.getNodeFromId("node_id")
save_preview(node, "height")

# 传入纹理对象也行
tex = node.getPropertyValue(out_props[0]).get()
save_preview(tex, "height")

# 自定义缩放比(默认 4 即 1/4)
save_preview(node, "height_hires", scale=2)  # 1/2 大小
save_preview(node, "height_full", scale=1)   # 原始大小

参数:

参数 类型 默认 说明
texture_or_node SDTexture / SDNode 必填 传 node 时自动取第一个输出端口
label str "preview" 显示标签,也用于文件名
scale int 4 缩小倍数(1=原始, 2=半, 4=四分之一)
quality int 80 JPEG 质量

[IMAGE:path] 标记(底层机制)

save_preview 内部调用 print(f"[IMAGE:{path}]"),MCP Server 自动将图片 base64 嵌入返回。 也可以手动使用这个标记:

tex.save("path/to/file.jpg")
print(f"[IMAGE:path/to/file.jpg]")  # AI 看到图片

操作示例

1. 截图单个节点

node = graph.getNodeFromId("1567699435")
save_preview(node, "weave_pattern")

2. 截取所有 PBR 输出

output_nodes = graph.getOutputNodes()
for i in range(output_nodes.getSize()):
    on = output_nodes.getItem(i)
    usage = "unknown"
    try:
        val = on.getAnnotationPropertyValueFromId("identifier")
        if val:
            usage = str(val.get()) if hasattr(val, 'get') else str(val)
    except Exception:
        pass
    save_preview(on, f"output_{usage}")

3. 截取关键中间节点

check_nodes = {
    "1567699435": "weave_pattern",
    "1567699547": "height_levels",
    "1567699553": "final_blend",
}
for nid, label in check_nodes.items():
    node = graph.getNodeFromId(nid)
    if node:
        save_preview(node, label)
    else:
        print(f"节点 {nid} ({label}) 未找到")

4. 多输出端口的库节点

node = graph.getNodeFromId("target_node_id")
if node:
    out_props = node.getProperties(SDPropertyCategory.Output)
    for p in out_props:
        port_id = p.getId()
        val = node.getPropertyValue(p)
        if val:
            tex = val.get()
            if tex:
                save_preview(tex, f"port_{port_id}")

sd-node-capture is a skill published in the GitHub repository IvanYangYangXi/artclaw_bridge (35 stars, last pushed 4mo ago), licensed MIT. It adds 106 tokens to every session and 1,476 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
