create-plugin

An interactive guide for creating a new Obsidian plugin, including automated and manual setup options. Obsidian is a note-taking app whose features can be extended with plugins.

In plain words
What is it for?
Use it to generate or manually build a plugin starter structure, then adapt it to the plugin's intended behavior.
Why use it?
It helps set up the required project files and apply basic quality, accessibility, and cleanup practices from the beginning.

Command for Claude Code

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.

Made for: Claude Code.

Per session 13 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 391 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

create-plugin 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 2d 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.

What it actually says

You are helping the user create a new Obsidian plugin. Follow these steps:

Setup Options

Present the user with two options:

  1. Automated Setup (Recommended): Use the interactive boilerplate generator script

    • Run: node /path/to/obsidian-plugin-skill/tools/create-plugin.js
    • This creates a minimal, best-practice plugin structure automatically
    • Detects existing projects and only adds missing files
    • All generated code follows the Obsidian Plugin Development Skill guidelines
  2. Manual Setup: Guide the user through creating files step-by-step

    • Walk through each required file
    • Explain what each file does
    • Provide code that follows best practices from the skill

After Setup

Once the boilerplate is created (either way):

  1. Verify all files follow the skill's best practices:

    • No sample code (MyPlugin, SampleModal, etc.)
    • Proper use of registerEvent() for cleanup
    • Sentence case in UI text
    • Obsidian CSS variables in styles
    • Accessibility-ready templates
  2. Help customize the plugin:

    • Ask what the plugin will do
    • Suggest appropriate API usage patterns
    • Reference specific sections of the skill as needed
  3. Guide through initial development:

    • Setting up the dev environment
    • Testing in Obsidian
    • Common next steps

Important Reminders

  • Always apply the Obsidian Plugin Development Skill guidelines
  • Ensure accessibility from the start (keyboard navigation, ARIA labels, focus indicators)
  • Use TypeScript best practices (instanceof, not type casting)
  • Follow memory management rules (proper event registration)
  • Use Obsidian CSS variables for theming

Ask the user which setup option they prefer, then proceed accordingly.

Changes

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.
