APIMesh CLAUDE.md

APIMesh CLAUDE.md is an instructions file for coding agents from mbeato/APIMesh. It costs 723 tokens per session, scanned A, a copy of claude-peers-mcp CLAUDE.md, MIT.

Repository instructions for APIMesh, a software project, that standardise how developers run Bun, build the frontend, use databases and write tests.

In plain words
What is it for?
Use them when changing APIMesh's APIs, frontend, database code or tests, especially when deciding between Bun and equivalent Node.js tools.
Why use it?
They reduce inconsistent tooling choices and help coding agents follow the project's expected commands and libraries.

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.

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

APIMesh CLAUDE.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 5d 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

88% identical to claude-peers-mcp CLAUDE.md — 35 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.

How it starts

The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Default to using Bun instead of Node.js.

  • Use bun <file> instead of node <file> or ts-node <file>
  • Use bun test instead of jest or vitest
  • Use bun build <file.html|file.ts|file.css> instead of webpack or esbuild
  • Use bun install instead of npm install or yarn install or pnpm install
  • Use bun run <script> instead of npm run <script> or yarn run <script> or pnpm run <script>
  • Use bunx <package> <command> instead of npx <package> <command>
  • Bun automatically loads .env, so don't use dotenv.

APIs

  • Bun.serve() supports WebSockets, HTTPS, and routes. Don't use express.
  • bun:sqlite for SQLite. Don't use better-sqlite3.
  • Bun.redis for Redis. Don't use ioredis.
  • Bun.sql for Postgres. Don't use pg or postgres.js.
  • WebSocket is built-in. Don't use ws.
  • Prefer Bun.file over node:fs's readFile/writeFile
  • Bun.$ls instead of execa.

Testing

Use bun test to run tests.

import { test, expect } from "bun:test";

test("hello world", () => {
  expect(1).toBe(1);
});

Frontend

Use HTML imports with Bun.serve(). Don't use vite. HTML imports fully support React, CSS, Tailwind.

Server:

import index from "./index.html"

Bun.serve({
  routes: {
    "/": index,
    "/api/users/:id": {
      GET: (req) => {
        return new Response(JSON.stringify({ id: req.params.id }));
      },
    },
  },
  // optional websocket support
  websocket: {
    open: (ws) => {
      ws.send("Hello, world!");
    },
    message: (ws, message) => {
      ws.send(message);
    },
    close: (ws) => {
      // handle close
    }
  },
  development: {
    hmr: true,
    console: true,
  }
})

HTML files can import .tsx, .jsx or .js files directly and Bun's bundler will transpile & bundle automatically. <link> tags can point to stylesheets and Bun's CSS bundler will bundle.

<html>
  <body>
    <h1>Hello, world!</h1>
    <script type="module" src="./frontend.tsx"></script>
  </body>
</html>

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.
