@codluv/llmtxt

@codluv/llmtxt

Portable llmtxt primitives for TypeScript and Node.js.

@codluv/llmtxt wraps the Rust llmtxt-core crate through WASM so TypeScript consumers use the same single-source-of-truth logic as native Rust consumers.

Install

npm install @codluv/llmtxt

Optional LAFS envelope validation:

npm install @cleocode/lafs

Core Primitives

import {
  compress,
  decompress,
  generateId,
  hashContent,
  generateSignedUrl,
  createPatch,
  applyPatch,
} from '@codluv/llmtxt';

const compressed = await compress('Hello world');
const text = await decompress(compressed);
const slug = generateId();
const hash = hashContent(text);

const patch = createPatch('hello\n', 'hello world\n');
const rebuilt = applyPatch('hello\n', patch);

Attachment Client Helpers

import { createClient } from '@codluv/llmtxt';

const client = createClient({
  apiBase: 'https://api.signaldock.io',
  apiKey: 'sk_live_...',
  agentId: 'my-agent',
});

const upload = await client.upload('conv_123', '# Shared note');
const owned = await client.fetchOwned(upload.slug);
const shared = await client.fetchFromConversation(upload.slug, 'conv_123');

const reshare = await client.reshare(upload.slug, {
  mode: 'signed_url',
  expiresIn: 3600,
});

const version = await client.addVersionFromContent(
  upload.slug,
  owned.content,
  owned.content + '\n\nAppendix',
  { changelog: 'Add appendix' },
);

What Ships

• compression, hashing, base62, token estimation
• signed URL generation and verification
• unified diff patch creation and application
• attachment access helpers for signed URL, owner, and conversation reads
• attachment re-share and version submission helpers
• optional LAFS response parsing when @cleocode/lafs is installed

Release Model

The npm package includes prebuilt WASM artifacts generated from the Rust crate in crates/llmtxt-core, so TypeScript and Rust consumers stay aligned on behavior.
