json-canvas skill for Claude Code, Codex and Cursor

Install

Each tab says whether it installs commit c0e3bc4, the one we checked, or the latest version.

No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie, Amp and Antigravity, and Claude Code for Cline. Kiro needs the folder copied by hand.

Pinned to commit c0e3bc4, the one we checked.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/anbeime/skill.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin c0e3bc4827b470fe4dbd93758ae45406c0f35e54 &&
  git -C "$tmp" sparse-checkout set -- skills/obsidian-skills-integrated/json-canvas &&
  git -C "$tmp" checkout -q c0e3bc4827b470fe4dbd93758ae45406c0f35e54 &&
  mkdir -p .claude/skills &&
  mkdir .claude/skills/json-canvas &&
  cp -R "$tmp"/skills/obsidian-skills-integrated/json-canvas/. .claude/skills/json-canvas/ &&
  rm -rf "$tmp"

If Claude Code was already running and this created the skills folder, run /reload-skills.

Skills in the Claude apps belong to your account rather than to a project.

Make json-canvas.zip, with the skill folder at the top level:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/anbeime/skill.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin c0e3bc4827b470fe4dbd93758ae45406c0f35e54 &&
  git -C "$tmp" sparse-checkout set -- skills/obsidian-skills-integrated/json-canvas &&
  git -C "$tmp" checkout -q c0e3bc4827b470fe4dbd93758ae45406c0f35e54 &&
  out="$(mktemp -d)" &&
  cp -R "$tmp"/skills/obsidian-skills-integrated/json-canvas "$out"/json-canvas &&
  (cd "$out" && zip -qr - json-canvas) > json-canvas.zip &&
  rm -rf "$tmp" "$out"

In Claude, open Customize > Skills, select +, then + Create skill > Upload a skill, and choose json-canvas.zip.

On Free, Pro and Max plans, turn on Code execution and file creation (Create and edit files in newer settings) under Settings > Capabilities.

In a running Copilot CLI session, run /skills reload.

Or install it with gh skill, which also installs the commit we checked. Needs GitHub CLI 2.90 or later.

gh skill install anbeime/skill skills/obsidian-skills-integrated/json-canvas/SKILL.md@c0e3bc4827b470fe4dbd93758ae45406c0f35e54 --agent github-copilot --scope project

Copilot & VS Code docs

Pinned to commit c0e3bc4, the one we checked.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/anbeime/skill.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin c0e3bc4827b470fe4dbd93758ae45406c0f35e54 &&

  cp -R "$tmp"/skills/obsidian-skills-integrated/json-canvas/. .gemini/skills/json-canvas/ &&
  rm -rf "$tmp"

In a running session, run /skills reload.

Or use Gemini CLI’s own installer. Installs the latest version, not the one we checked.

gemini skills install https://github.com/anbeime/skill.git --path skills/obsidian-skills-integrated/json-canvas --scope workspace

Gemini CLI docs

Pinned to commit c0e3bc4, the one we checked.

Codex, Cursor, Copilot, VS Code, Gemini CLI, OpenCode, Goose, Amp and Zed all read .agents/skills; Claude Code and Kiro list only their own folders.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/anbeime/skill.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin c0e3bc4827b470fe4dbd93758ae45406c0f35e54 &&
  git -C "$tmp" sparse-checkout set -- skills/obsidian-skills-integrated/json-canvas &&
  git -C "$tmp" checkout -q c0e3bc4827b470fe4dbd93758ae45406c0f35e54 &&
  mkdir -p .agents/skills &&
  mkdir .agents/skills/json-canvas &&
  cp -R "$tmp"/skills/obsidian-skills-integrated/json-canvas/. .agents/skills/json-canvas/ &&
  rm -rf "$tmp"

Or use the skills CLI from skills.sh. Installs the latest version, not the one we checked. The skills CLI reports installs to skills.sh unless you set DISABLE_TELEMETRY=1.

npx skills@1.7.4 add anbeime/skill --skill json-canvas

Agent Skills docs

What it can touch

From the files and frontmatter at commit c0e3bc4. This is how much a skill can do, not whether it is risky.

What it can touch: Scripts or outside hosts

Names web addresses
It mentions outside web addresses the agent may visit. We list them but don't follow them.

Pattern check

Pattern check: nothing flagged · commit c0e3bc4 · 27 Oct 2026

We checked every text file in this skill, at commit c0e3bc4 on 27 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

Agent Skills specPasses with warnings
The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.
- Warning
  The body is 651 lines; the spec suggests under 500. B1
  Fix: Move detailed sections into reference files and link to them from SKILL.md.
- Note
  The description doesn't say when to use the skill. D6
  Fix: Add a sentence such as "Use when …" naming the requests or files that should trigger it.
- Note
  There is no license field, so readers can't tell whether they may reuse the skill. O2
  Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Note
  The body is 651 lines; the spec suggests under 500. Claude Code's docs say the same. B1
  Fix: Move detailed sections into reference files and link to them from SKILL.md.
Claude apps & API uploadPasses
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Note
  The body is 651 lines; the spec suggests under 500. Anthropic's guidance says the same. B1
  Fix: Move detailed sections into reference files and link to them from SKILL.md.
OpenAI (Codex & API)Passes
VS Code & CopilotPasses
