24 alternatives to Generate SKILL.md files from URLs, in the browser

I created this tool after writing a few agent skills by hand and noticing this pattern was repetitive. Paste a documentation URL, enter your own model API key, and it gets the page content client-side to create a reusable SKILL.md. There is no backend/proxy, so it stays as secure as possible. I would like feedback on the structure of the output and the edge cases.

This browser-based tool generates SKILL.md files from documentation URLs, designed for developers building AI agent skills. Users paste a URL, provide their own model API key, and the tool extracts page content… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    We recently shipped the Tiptap AI Toolkit (https://tiptap.dev/docs/content-ai/capabilities/ai-toolkit/o...), which lets developers embed LLM-powered editing into rich text editors. Now we’re exploring the next step: making agents operate on documents without a browser involved. The idea is a server-side system where agents can read, write, and transform documents in real time — essentially treating your document layer as a programmable data store that agents can interact with directly. Internally we’ve been joking about the name “real-time agentic document…

    Feels a bit like Figma, but for coding agents. Instead of going back and forth with prompts, you give the agent a DESIGN.md that defines the design system up front, and it generally sticks to it when generating UI. Google Stitch seems to be moving in this direction as a standard, so we put together a small collection of DESIGN.md files based on popular web sites.

    npx agentseed init AGENTS.md (https://agents.md) is a standard file used by AI coding agents to understand a repo (stack, commands, conventions). Agentseed generates it directly from the codebase using static analysis. Optional LLM augmentation is supported by bringing your own API key. Extracts languages, frameworks, dependencies, build/test commands, directory structure, and monorepo boundaries.

    Hey all! I'm the maintainer of mistral.rs. I just landed support for OpenAI-compatible Agent Skills via a /v1/skills endpoint, and it works with local open models. Until now Skills have basically been locked to closed models, and with the ability to have private, local intelligence becoming increasingly important, but this feature allows you to do XYZ with local models. It's fully compatible with OpenAI's /v1/skills API, so you can drop mistral.rs into your existing code with minimal difficulty. We support the accompanying tools too: /v1/files or input_file for…

    Hey HN! Built a template for distributing AI agent skills via npm. Problem: AI coding tools (Claude Code, Cursor, Windsurf) support custom "skills" but distribution is manual - copy files to ~/.tool/skills/, repeat for updates, no versioning. Solution: Standard npm packages with lifecycle hooks: npm install -g @org/my-skill npm update -g @org/my-skill Benefits: - Semantic versioning (^1.2.0 for auto-updates) - Private registries for enterprise - Standard CI/CD integration - Discoverable on npmjs.com It's a GitHub template - fork, customize SKILL.md, publish.…

    I have been trying to create AI retool where tooling is done via AI, to create full stack apps like internal portals, ERP apps. Which led me to an architecture where we give ai pre build component, tools and let is just do the binding, content generation work to create full stack apps. With this approach in a single prompt AI is able to generate final config jsons using chained/looped agentic llm flow and we render a full stack app with the configs at the end. I have open sourced the whole project whole code, app builder, agentic architecture, backend for you to use. Github:…

    Hey HN. I built a security registry for AI agent skills. There are 64k skills on Vercel's skills.sh. Cursor, Claude Code, Windsurf, and dozens more agents pull them from GitHub at HEAD — no versioning, signing, or scanning. The OpenClaw agents themselves flagged this: "The supply chain attack nobody is talking about: skill.md is an unsigned binary."[0] I took an official skill that packages other skills, added a few lines of Python to exfiltrate env vars, shell history, and git config, and installed it into Claude Code and Codex. Claude Code ran the script without flagging the outbound…

    Creating high-quality skills for Claude manually is complex, requiring specific technical knowledge of the file system structure (like SKILL.md), YAML metadata configuration, and precise prompt engineering to ensure the agent behaves correctly. MakeSkill eliminates this friction by automating the technical implementation. Instead of writing code and configuration files from scratch, users interact with MakeSkill's AI to refine their ideas. The platform then generates the complete, optimized skill package—following all best practices—ready to be downloaded and imported directly into Claude…

    I built a collection of webhook skills because AI coding agents are surprisingly bad at webhook integrations. The generated code looks reasonable until you run it, then signature verification fails, raw body handling is wrong, or the middleware order breaks everything. PostHog's research on LLM code generation (https://posthog.com/blog/correct-llm-code-generation) found that agents produce more reliable code when referencing known-working examples rather than reconstructing from training data. That's the approach here. `webhook-skills` is a collection of provider-specific…
