Libretto

Libretto gives your coding agent superpowers for building, debugging, and maintaining browser RPA integrations.

It is designed for engineering teams that automate workflows in web apps and want to move from brittle browser-only scripts to faster, more reliable network-first integrations.

Installation

Install Libretto in your project with your favorite package manager:

npm install libretto playwright zod
yarn add libretto playwright zod
bun add libretto playwright zod
pnpm add libretto playwright zod

Then initialize Libretto:

npx libretto init

Usage

Libretto is usually used through prompts with the Libretto skill.

One-shot script generation

Use the Libretto skill. Go on LinkedIn and scrape the first 10 posts for content, who posted it, the number of reactions, the first 25 comments, and the first 25 reposts.

Interactive script building

Use the Libretto skill. Let's interactively build a script to scrape scheduling info from the eClinicalWorks EHR.

Convert browser automation to network requests

We have a browser script at ./integration.ts that automates going to Hacker News and getting the first 10 posts. Convert it to direct network scripts instead. Use the Libretto skill.

Fix broken integrations

We have a browser script at ./integration.ts that is supposed to go to Availity and perform an eligibility check for a patient. But I'm getting a broken selector error when I run it. Fix it. Use the Libretto skill.

You can also run workflows directly from the CLI:

npx libretto help
npx libretto run ./integration.ts main
