cortex-canvas
为某主题生成 .canvas 可视化文件。
触发场景
- 用户说"做一个 canvas / 把这些 concept 可视化"
- 用户给定一组 wikilink 或主题页 想看图
/cortex:canvas <topic>入口 (本插件无 commands, 由 skill 自决)
行为
- 解析 vault 路径 (
~/.claude/plugins/marketplaces/ccplugin-market/plugins/tools/cortex/scripts/hooks/_lib/resolve_vault.sh) - 探测
obsidianCLI:- 可用 → 调
obsidian canvas:create让 Obsidian 直接渲染 (TODO: 接口未稳定时退到静态 JSON) - 不可用 → 写静态 JSON Canvas 1.0 文件
- 可用 → 调
- 节点抽取规则 (按 topic):
- 若 topic 是文件 → 读其 frontmatter
up/related/sibling(Breadcrumbs 字段) 与[[wikilink]]出链 - 若 topic 是关键字 → 走
mcp__obsidian__obsidian_simple_search取 top 20
- 若 topic 是文件 → 读其 frontmatter
- 排版算法: force-directed grid, 5 列, 每节点 400×300, 间距 40
- 输出到
<vault>/_assets/canvases/<topic-slug>.canvas - 不覆盖已存在的 canvas
JSON Canvas 1.0 格式
{
"nodes": [
{
"id": "n1",
"type": "file",
"file": "知识库/领域/foo.md",
"x": 0,
"y": 0,
"width": 400,
"height": 300
}
],
"edges": [
{
"id": "e1",
"fromNode": "n1",
"toNode": "n2",
"fromSide": "right",
"toSide": "left"
}
]
}
降级路径
- 无 obsidian CLI → 写静态 JSON 文件; 用户在 Obsidian 中点开即生效
- vault 无 canvases/ 目录 → 自动创建
- topic 无匹配节点 → 报告并 abort, 不写空 canvas
安全
- 永不覆盖现有 .canvas (重名 → 加
-N后缀) - 不修改任何已存在的 .md 文件
- canvas 仅是 vault 派生物, 用户可随时删除
参考
- JSON Canvas 1.0 spec: https://jsoncanvas.org/spec/1.0/
- Breadcrumbs frontmatter 字段约定 (research/03 §B.5)
