Write a skill once.
Compose it, maintain it, use it everywhere.

Skilnu is where AI agent skills get built, not just stored — connect once, use them from Claude, ChatGPT, or any MCP client.

What's a skill?

Plain-language instructions your agent actually follows

A short Markdown file that teaches an agent how to do something specific — review a pull request, write Terraform, run an incident runbook.

# TypeScript testing

Use vitest for all unit tests. Co-locate
test files next to the module under test.

- One `describe` block per exported function.
- Mock at the module boundary, never the
  network layer.

Skills anyone can write

Not just for developers

Non-technical teammates write these in minutes — no syntax to learn.

How I like writing

Tone, phrasing, words to avoid.

Code review checklist

What to flag, what to ignore.

Meeting notes format

Sections, owners, decisions.

How Skilnu is different

Compose

Build new skills from ones already in the catalog.

Maintain

Update once — every dependent skill follows.

Use anywhere

One connection, every MCP-compatible client.

Connect once

One URL, every agent

Paste this into Claude, ChatGPT, Codex, or any MCP client once you have an account. Full steps →
