What SkillVault is

SkillVault is a personal cloud vault for portable AI agent skills. You store a skill once: a name, a description, and your instructions (Markdown playbooks, reference docs, or executable scripts). SkillVault serves that capability across every tool you use: Claude Code, Cursor, Windsurf, ChatGPT, or your phone.

One library. Four delivery surfaces. The same playbooks everywhere.

Your skills stay in your private vault, protected by tokens you control and can rotate anytime. The link you share stays consistent, while rotatable tokens give you control over who can read or update your library.

The problem we are solving

AI assistants do not talk to each other. A skill you dialed in for Claude Code in your terminal is completely invisible to Cursor on your laptop. Neither tool can see the prompt or playbook you used on your phone this morning.

Every time you switch apps, accounts, or models, you start from scratch. You copy and paste instructions, re-explain your workflow, and waste time. SkillVault gives your AI skills a single home that every agent can reach.

How the vault works

SkillVault provides four clean ways to connect your skill library:

1. Private Vault URLs. Your vault lives at https://app.skillvault.dev/v/<username>. Web and mobile AI tools fetch clean Markdown formatted for LLM context windows (/v/<username>/t/<token>). Authorized agents can also update skills via dedicated write tokens (/v/<username>/p/<token>).

2. Local Agent Harnesses. The skillvault CLI drops lightweight wrapper files into detected local tools. Claude Code gets a SKILL.md file, Cursor gets .cursor/rules/skillvault.mdc, and tools like Windsurf, Aider, OpenCode, Codex, Cline, Hermes, Antigravity, and DeepSeek Harness get their native configurations.

3. Model Context Protocol (MCP). The native MCP endpoint (/mcp) lets platforms like Cursor, Windsurf, Claude Desktop, and ChatGPT Custom Connectors discover and call your skills as first-class tools during a conversation.

4. JSON REST API. Applications and CI/CD pipelines can query GET /api/v1/skills or inspect individual skills via standard Bearer-authenticated endpoints.

When you update a skill in your vault, it updates everywhere. The next time any tool calls your vault, it gets the latest version.

What lives in a skill

Each skill in your vault includes:

  • Name: A lowercase, hyphen-separated identifier unique to your vault.
  • Description: A quick summary that helps your AI know when to use this skill.
  • Body: Markdown instructions, step-by-step playbooks, or checklists for your agent.
  • Optional Files and Scripts: Attached templates, helper code, or API proxy rules.

There is no rigid structure. Write your instructions in simple Markdown, link references, and let your agents follow the steps.

How skills reach agents

Modern AI agents can fetch links, call MCP tools, or run terminal commands. SkillVault supports all of them:

  • Web and Mobile Chat: Paste your private vault URL into ChatGPT, Claude.ai, or mobile assistants that support web browsing. The model pulls your skill directly into the conversation.
  • MCP-Enabled Chatbots: Add your vault as an MCP connector to discover and run skills automatically.
  • Desktop Coding Agents: Tools like Claude Code, Cursor, and Windsurf read your local wrapper pointers, pulling instructions on demand.
  • Scripts and Workflows: Standard HTTP requests pull skill content with simple API keys.

What we do not do

We do not run model inference. SkillVault stores and delivers your capabilities. It does not decide how your AI thinks or process your prompts. The model you choose handles execution.

We do not track your prompts or train models on your data. Your vault belongs entirely to you.

Security and privacy

Your account password proves ownership. Separate vault tokens handle URL and API access. That separation lets you:

  • Rotate access tokens instantly from your dashboard without changing your password.
  • Issue read-only tokens or short-lived write tokens for specific sessions.
  • Revoke a token immediately if a device is lost or compromised.

Your data is stored in encrypted EU storage. All network traffic is encrypted via TLS.

How to start

  1. Create your account at /auth/signup to get your vault address (https://app.skillvault.dev/v/<username>).
  2. For desktop coding agents (Claude Code, Cursor, Windsurf), paste your link into your agent and say: Set up my skillvault https://app.skillvault.dev/v/<username>
  3. For web chats and mobile apps (ChatGPT, Claude.ai), paste your private read URL directly into your conversation.
