Linten: llms.txt Validator & Scaffolder

The complete validator, linter, link checker, and scaffolding tool for llms.txt and llms-full.txt files in Visual Studio Code. Built by Loopstates.

Overview

The /llms.txt specification provides structured, machine-readable reference documentation for LLMs, developer tools, and search crawlers.

Linten delivers complete in-editor validation, real-time diagnostics, broken link detection, token capacity estimation, and project scaffolding directly inside VS Code.

Key Features

Real-Time In-Editor Diagnostics: Instant syntax and structural validation according to the llms.txt standard (single H1 title, blockquote summary, section hierarchy, and link formats).
Link Health Checker: Audits URLs in your documentation to detect broken links (404s), redirect loops, and server errors.
Visual Audit Dashboard: Interactive dashboard displaying overall compliance score, token context breakdown, findings list, and an interactive link health table with jump-to-line navigation.
Dedicated Sidebar: Activity Bar view showing real-time document score, model context usage, link status chips, and quick action shortcuts.
Token Context Estimator: Estimates token usage and measures document footprint against context windows for Gemini 2.0, Claude 3.5, GPT-4o, and DeepSeek.
27 Starter Templates: Ready-to-use presets for SaaS, DevTools, REST APIs, Documentation, E-Commerce, Open Source, and AI platforms.
Website Scaffolder: Generate starter llms.txt documentation from any website domain or URL.
Companion llms-full.txt Compiler: Synthesizes and bundles referenced documentation sections into a full-text companion reference.
1-Click QuickFixes: Code actions to convert bare URLs into spec-compliant markdown anchors (- [Title](https://github.com/loopstates/linten/blob/HEAD/url): Description) and insert missing headers.
README Badges: Generate markdown and SVG compliance badges for your repository README.
Terminal CLI: Integrated terminal support with the linten command-line utility.
