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.

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 | $0.00082 | $0.01159 |
| Opus 5.5 | $0.00033 | $0.00464 |
| Sonnet 5.5 | $0.00016 | $0.00232 |
| Haiku 4.5 | $0.00008 | $0.00116 |
Grade A, and why
intlayer-backend 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 22d 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.
This is a copy
100% identical to intlayer-backend — 0 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Intlayer Backend Usage
Core Philosophy
Every backend integration works the same way:
- A middleware / plugin (
intlayer()) resolves the locale of each request (cookie, header,Accept-Language) and scopes it to that request. - Helpers (
t,getIntlayer,getDictionary) read that request locale, so they are safe to call from services without threading a locale argument through every function.
| Framework | Package | Registration |
|---|---|---|
| Express | express-intlayer |
app.use(intlayer()) |
| NestJS | express-intlayer |
consumer.apply(intlayer()).forRoutes("*") |
| Fastify | fastify-intlayer |
await fastify.register(intlayer) |
| Hono | hono-intlayer |
app.use("*", intlayer()) |
| Elysia | elysia-intlayer |
.use(intlayer()), helpers read from route intlayer |
| AdonisJS | adonis-intlayer |
Registered middleware (see the AdonisJS guide) |
Declare Content
File: src/index.content.ts
import { t, type Dictionary } from "intlayer";
const content = {
key: "index",
content: {
exampleOfContent: t({
en: "Example of returned content in English",
fr: "Exemple de contenu renvoyé en français",
}),
},
} satisfies Dictionary;
export default content;
Usage
Register the middleware / plugin from the table above before the routes that read content (see the Express guide), then call the helpers in any handler:
import { t, getIntlayer, getDictionary } from "express-intlayer";
import dictionaryExample from "./index.content";
app.get("/", (_req, res) => {
res.send(t({ en: "Hello", fr: "Bonjour" })); // Inline translation
});
app.get("/by-key", (_req, res) => {
res.send(getIntlayer("index").exampleOfContent); // Dictionary by key
});
app.get("/by-import", (_req, res) => {
res.send(getDictionary(dictionaryExample).exampleOfContent); // Imported dictionary
});
What ships with it
24 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

intlayer-backend is a skill published in the GitHub repository aymericzip/intlayer-skills (5 stars, last pushed 16d ago), licensed Apache-2.0. It adds 82 tokens to every session and 1,159 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to intlayer-backend, differing in 0 lines, and is treated as a copy.
