llmtxt

Primitives and SDK for LLM agent content workflows.

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 llmtxt

Primitives

import {
  compress, decompress, generateId, hashContent,
  createPatch, applyPatch, generateSignedUrl,
} from '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);

SDK (Collaborative Documents)

import {
  isValidTransition, evaluateApprovals, planRetrieval,
  reconstructVersion, attributeVersion, buildContributorSummary,
} from 'llmtxt/sdk';

Subpath Exports

import { generateOverview, getSection } from 'llmtxt/disclosure';
import { textSimilarity, rankBySimilarity } from 'llmtxt/similarity';
import { buildGraph } from 'llmtxt/graph';

What Ships

• Compression, hashing, base62, token estimation (Rust WASM)
• Signed URL generation and verification
• Unified diff patch creation, application, version reconstruction
• Progressive disclosure: overview, section extraction, content search
• Collaborative document lifecycle (DRAFT, REVIEW, LOCKED, ARCHIVED)
• Version stack management with attribution tracking
• Consensus/approval evaluation with stale review handling
• Token-budget-aware retrieval planning
• Storage content reference abstractions (inline vs object-store)
• Attachment client helpers for upload, fetch, reshare, versioning

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.
