What it does

JSON Canvas is an agent skill from anbeime/skill. 产品经理与内容创作者在构建Obsidian知识库或梳理复杂逻辑时,当需要创建思维导图、流程图等可视化画布,使用此技能可自动生成标准.canvas文件,精准配置节点、连线与层级,一键生成完美排版,彻底告别手写JSON的繁琐与报错。

Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Obsidian. The repository describes itself as: 收录最全、更新最快的技能Skills商店:精选原创技能包(涵盖文档处理、内容创作、编程开发、机器学习、自动化工作流),全部打包好可直接安装使用!同时自动抓取GitHub上万个Skills项目,按分类、更新时间、Star数量整理。The most comprehensive and frequently updated AI Agent skill…

Example prompts

  • “/json-canvas”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. All id values must be unique across nodes and edges
  2. fromNode and toNode must reference existing node IDs
  3. Required fields must be present for each node type
  4. type must be one of: text, file, link, group
  5. backgroundStyle must be one of: cover, ratio, repeat
  6. fromSide, toSide must be one of: top, right, bottom, left
  7. fromEnd, toEnd must be one of: none, arrow
  8. Color presets must be "1" through "6" or valid hex color

What it can do on your machine

Read from SKILL.md and the folder at commit b8dadc0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • obsidian.md

    Also links to:

    • jsoncanvas.org
    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

JSON Canvas loads about 3.6k tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 741 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~3.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 741 words (~3,572 tokens).

“This skill enables skills-compatible agents to create and edit valid JSON Canvas files (.canvas) used in Obsidian and other applications.”

How do I install JSON Canvas in Claude Code?

Run `npx skills add anbeime/skill --skill json-canvas -a claude-code`. Or copy the skill folder (skills/obsidian-skills-integrated/json-canvas in anbeime/skill) into .claude/skills/json-canvas in your project. Claude Code loads it when a task matches its description.

How do I install JSON Canvas in Codex?

Run `npx skills add anbeime/skill --skill json-canvas -a codex`. Or copy the skill folder (skills/obsidian-skills-integrated/json-canvas in anbeime/skill) into .agents/skills/json-canvas in your project. Codex loads it when a task matches its description.

Can I use JSON Canvas in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add anbeime/skill --skill json-canvas -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/json-canvas, .gemini/skills/json-canvas, .github/skills/json-canvas and .opencode/skills/json-canvas in your project.

What does JSON Canvas need to run?

SKILL.md names no scripts, command-line tools or credentials: JSON Canvas is instructions for the agent only.

Does JSON Canvas access the network?

SKILL.md names 3 domains. In commands or code: obsidian.md; the agent is likely to contact it when it follows the instructions. As links in the text: jsoncanvas.org and github.com. This is read from the text; nothing was executed.

Is JSON Canvas safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does JSON Canvas use?

No licence was found for JSON Canvas or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does JSON Canvas use?

About 3.6k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to JSON Canvas?
