What it does

Inlang I18n is an agent skill from aidenlx/zotlit. Define ZotLit UI messages in the Inlang Message Format and consume them through the generated JSON Language Pack facade. Use when editing messages/.json, adding interpolation or variants, changing locale resolution, or working with m. calls.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Internationalization. It works with Obsidian. The repository describes itself as: Bring your Zotero library into Obsidian. Create literature notes, insert citations, and annotate PDFs without leaving your vault. The licence is AGPL-3.0.

When your agent uses it

Editing messages/.json
Adding interpolation
Changing locale resolution

Example prompts

“/inlang-i18n”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

Add or edit the key in messages/en.json. Use snake_case; keys prefixed
Regenerate the facade when running package tools directly.
Import the facade and keep named-input call shapes

What it can do on your machine

Read from SKILL.md and the folder at commit 27f5752. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- pnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Inlang I18n loads about 1k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 315 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~64
When it runs · the whole SKILL.md, loaded when a task matches: ~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Inlang messages + JSON Language Packs

Use messages/{locale}.json as the source of truth. The Obsidian build compiles those sources into a typed message facade and bundled English Language Pack; the runtime interprets pack data synchronously.

Pair this skill with /i18n-ui-text when writing English UI copy.

Project layout

project.inlang/settings.json — Inlang project configuration, base locale, and locale list.
messages/{locale}.json — shared message sources.
apps/obsidian/scripts/generate-language-packs.ts — compiler entry point.
apps/obsidian/src/lib/i18n/generated/messages.ts — generated typed facade.
apps/obsidian/src/lib/i18n/generated/en.json — bundled English pack.
apps/obsidian/src/lib/i18n/runtime.ts — eval-free interpreter.
apps/obsidian/src/lib/i18n.ts — Obsidian Locale Alias resolution and startup.

Generated files are gitignored. Run:

pnpm --filter @zotlit/obsidian generate:language-packs

Turbo runs generation before typecheck and tests. Vite regenerates at build start and watches the message sources, project settings, and generator.

Adding or changing a message

Add or edit the key in messages/en.json. Use snake_case; keys prefixed docs_ belong only to the docs site and are excluded from plugin artifacts.
Regenerate the facade when running package tools directly.
Import the facade and keep named-input call shapes:

import * as m from "@/lib/i18n/generated/messages";

m.welcome_view_name();
m.annot_view_filter_count({ shown: 3, total: 8 });

Input-free messages are functions with no arguments. Input-bearing messages take one object whose required properties come from input declarations.

Inlang Message Format

Simple messages

json

{
  "hello_world": "Hello world",
  "greeting": "Good morning {name}!"
}

Variables use {curlyBraces}. Escape literal braces with \\{ and \\} in JSON.

Variants

Wrap structured messages in an array:

json

{
  "item_count": [
    {
      "declarations": ["input count", "local category = count: plural"],
      "selectors": ["category"],
      "match": {
        "category=one": "There is one item.",
        "category=*": "There are {count} items."
      }
    }
  ]
}

Declarations run in source order:

input name declares a facade input.
local result = source: formatter derives a local value.
Formatter options are key=value; $inputName references another input.

Matching is evaluated in source order. Use literal matches where needed and * as the catch-all.

Supported formatters

Formatter	Runtime
`plural`	`Intl.PluralRules`
`number`	`Intl.NumberFormat`
`datetime`	`Intl.DateTimeFormat`

Examples:

json

{
  "price": [
    {
      "declarations": [
        "input amount",
        "input currency",
        "local formatted = amount: number style=currency currency=$currency"
      ],
      "match": { "formatted=*": "Price: {formatted}" }
    }
  ],
  "event_date": [
    {
      "declarations": [
        "input date",
        "local formatted = date: datetime dateStyle=long timeZone=UTC"
      ],
      "match": { "formatted=*": "Date: {formatted}" }
    }
  ]
}

Use an explicit timeZone when output must be stable across environments.

Markup, unknown declarations, unknown expressions, and unknown formatters are rejected by the compiler.

Locale behavior

apps/obsidian/src/lib/i18n.ts resolves Obsidian language codes through the Locale Alias table. Canonical locale names follow Inlang (zh-CN); unmatched codes resolve to English. Startup always installs bundled English first. Downloaded Language Packs are pure JSON data and use the same generated facade.
