Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.02502 |
| Opus 5.5 | $0.00014 | $0.01001 |
| Sonnet 5.5 | $0.00007 | $0.00500 |
| Haiku 4.5 | $0.00003 | $0.00250 |
Grade A, and why
devlab-web-xyflow-usage 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 1mo 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.

库信息
| 项 | 值 |
|---|---|
| 名称 | @xyflow/react (React Flow) |
| GitHub | https://github.com/xyflow/xyflow |
| 官方文档 | https://reactflow.dev |
| npm | https://www.npmjs.com/package/@xyflow/react |
| 当前版本 | ^12.11.1 |
| 核心能力 | 节点-边画布、自定义节点/边类型、zoom/pan、拖拽、连线、子流程 |
| 体积 | ~150KB (react + xyflow) |
适用场景
- 需要可交互的节点-边画布（流程图、拓扑图、生命周期地图等）
- 节点需要完全自定义 DOM 结构
- 需要 zoom/pan/fitView 画布控制
- 需要节点展开/折叠、点击交互
- 已有 React 19 环境
不适用场景
- 简单的时间线/甘特图 → 用 vis-timeline 或纯 CSS
- 纯静态的流程图展示 → 用 SVG/Canvas 直接画
- 需要亚像素级精度的图表 → 用 ECharts/D3
核心概念
节点 (Node)
interface Node {
id: string; // 唯一标识
type: string; // 对应 nodeTypes 中的组件名
position: { x: number; y: number }; // 画布坐标
data: Record<string, unknown>; // 传递给自定义节点的数据
}
边 (Edge)
interface Edge {
id: string;
source: string; // 源节点 id
target: string; // 目标节点 id
type?: string; // 对应 edgeTypes 中的组件名
animated?: boolean;
style?: CSSProperties;
}
自定义节点
import { Handle, Position, type NodeProps } from "@xyflow/react";
function MyNode({ data }: NodeProps) {
return (
<div className="my-node">
<Handle type="target" position={Position.Left} />
{/* 自定义内容 */}
<Handle type="source" position={Position.Right} />
</div>
);
}
const nodeTypes = { my: MyNode };
画布配置
<ReactFlow
nodes={nodes}
edges={edges}
nodeTypes={nodeTypes}
colorMode="dark" // 暗色主题
fitView // 自动适配视口
nodesDraggable={false} // 禁止拖拽节点
nodesConnectable={false} // 禁止连线
elementsSelectable={false}
panOnDrag={false} // 禁止画布平移
preventScrolling={false} // 允许页面滚动
/>

What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 1mo ago First seen · 192 lines · 35 tokens per session scan A 004be02bd5ad
devlab-web-xyflow-usage is a skill published in the GitHub repository seed-forge/harness-ai-kit (25 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 35 tokens to every session and 2,502 once invoked, about $0.0001 per session on Opus 5.5. 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.
