mcp-server AGENTS.md

mcp-server AGENTS.md is an instructions file for Codex, OpenCode from senseiBas/mcp-server. It costs 2,238 tokens per session, scanned A, a copy of obsidian-sidekick AGENTS.md, 0BSD.

Project instructions for developing an Obsidian community plugin, an extension that adds features to the Obsidian note-taking app. They describe the TypeScript entry point, required release files, and the tools used to build and check it.

In plain words
What is it for?
Use them when working on this Obsidian plugin's development, watch mode, production build, or linting. They cover npm, esbuild, TypeScript, and the required output files.
Why use it?
They give an agent the project-specific rules needed to install dependencies, develop safely, and create a usable plugin release. This avoids guessing how the project is structured or built.

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

mcp-server AGENTS.md 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 3d 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.

Origin

This is a copy

94% identical to obsidian-sidekick AGENTS.md — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Obsidian community plugin

Project overview

  • Target: Obsidian Community Plugin (TypeScript → bundled JavaScript).
  • Entry point: main.ts compiled to main.js and loaded by Obsidian.
  • Required release artifacts: main.js, manifest.json, and optional styles.css.

Environment & tooling

  • Node.js: use current LTS (Node 18+ recommended).
  • Package manager: npm (required for this sample - package.json defines npm scripts and dependencies).
  • Bundler: esbuild (required for this sample - esbuild.config.mjs and build scripts depend on it). Alternative bundlers like Rollup or webpack are acceptable for other projects if they bundle all external dependencies into main.js.
  • Types: obsidian type definitions.

Note: This sample project has specific technical dependencies on npm and esbuild. If you're creating a plugin from scratch, you can choose different tools, but you'll need to replace the build configuration accordingly.

Install

npm install

Dev (watch)

npm run dev

Production build

npm run build

Linting

  • To use eslint install eslint from terminal: npm install -g eslint
  • To use eslint to analyze this project use this command: eslint main.ts
  • eslint will then create a report with suggestions for code improvement by file and line number.
  • If your source code is in a folder, such as src, you can use eslint with this command to analyze all files in that folder: eslint ./src/

File & folder conventions

  • Organize code into multiple files: Split functionality across separate modules rather than putting everything in main.ts.
  • Source lives in src/. Keep main.ts small and focused on plugin lifecycle (loading, unloading, registering commands).
  • Example file structure:
    src/
      main.ts           # Plugin entry point, lifecycle management
      settings.ts       # Settings interface and defaults
      commands/         # Command implementations
        command1.ts
        command2.ts
      ui/              # UI components, modals, views
        modal.ts
        view.ts
      utils/           # Utility functions, helpers
        helpers.ts
        constants.ts
      types.ts         # TypeScript interfaces and types
    
  • Do not commit build artifacts: Never commit node_modules/, main.js, or other generated files to version control.
  • Keep the plugin small. Avoid large dependencies. Prefer browser-compatible packages.
  • Generated output should be placed at the plugin root or dist/ depending on your build setup. Release artifacts must end up at the top level of the plugin folder in the vault (main.js, manifest.json, styles.css).

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.
