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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01447 | $0.01447 |
| Opus 5.5 | $0.00579 | $0.00579 |
| Sonnet 5.5 | $0.00289 | $0.00289 |
| Haiku 4.5 | $0.00145 | $0.00145 |
Grade A, and why
docsGround CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Default to using Bun instead of Node.js.
- Use
bun <file>instead ofnode <file>orts-node <file> - Use
bun testinstead ofjestorvitest - Use
bun build <file.html|file.ts|file.css>instead ofwebpackoresbuild - Use
bun installinstead ofnpm installoryarn installorpnpm install - Use
bun run <script>instead ofnpm run <script>oryarn run <script>orpnpm run <script> - Use
bunx <package> <command>instead ofnpx <package> <command> - Bun automatically loads .env, so don't use dotenv.
APIs
Bun.serve()supports WebSockets, HTTPS, and routes. Don't useexpress.bun:sqlitefor SQLite. Don't usebetter-sqlite3.Bun.redisfor Redis. Don't useioredis.Bun.sqlfor Postgres. Don't usepgorpostgres.js.WebSocketis built-in. Don't usews.- Prefer
Bun.fileovernode:fs's readFile/writeFile - Bun.$
lsinstead 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.

<h1>Hello, world!</h1>

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.
