🌟 Introduction

GenAIScript is a powerful scripting environment tailored for building and managing Large Language Model (LLM) prompts with ease. Whether you are a developer, data scientist, or researcher, GenAIScript provides the tools you need to create, debug, and share scripts efficiently.

🤖 This readme is maintained by the readme-updater script.

🚀 Quickstart Guide

Get started quickly by installing the Visual Studio Code Extension or using the command line.

✨ Features

🎨 Stylized JavaScript & TypeScript

Build prompts programmatically using JavaScript or TypeScript.

def("FILE", env.files, { endsWith: ".pdf" })
$`Summarize FILE. Today is ${new Date()}.`

🚀 Fast Development Loop

Edit, Debug, Run, and Test your scripts in Visual Studio Code or with the command line.

🔗 Reuse and Share Scripts

Scripts are files! They can be versioned, shared, and forked.

// define the context
def("FILE", env.files, { endsWith: ".pdf" })
// structure the data
const schema = defSchema("DATA", { type: "array", items: { type: "string" } })
// assign the task
$`Analyze FILE and extract data to JSON using the ${schema} schema.`

📋 Data Schemas

Define, validate, and repair data using schemas.

const data = defSchema("MY_DATA", { type: "array", items: { ... } })
$`Extract data from files using ${data} schema.`

📄 Ingest Text from PDFs, DOCX, ...

Manipulate PDFs, DOCX, ...

def("PDF", env.files, { endsWith: ".pdf" })
const { pages } = await parsers.PDF(env.files[0])

📊 Ingest Tables from CSV, XLSX, ...

Manipulate tabular data from CSV, XLSX, ...

def("DATA", env.files, { endsWith: ".csv", sliceHead: 100 })
const rows = await parsers.CSV(env.files[0])
defData("ROWS", rows, { sliceHead: 100 })

📝 Generate Files

Extract files and diff from the LLM output. Preview changes in Refactoring UI.

$`Save the result in poem.txt.`

FILE ./poem.txt
The quick brown fox jumps over the lazy dog.

🔍 File Search

Grep or fuzz search files.

const { files } = await workspace.grep(/[a-z][a-z0-9]+/, { globs: "*.md" })

LLM Tools

Register JavaScript functions as tools.

defTool(
    "weather",
    "query a weather web api",
    { location: "string" },
    async (args) =>
        await fetch(`https://weather.api.api/?location=${args.location}`)
)

LLM Agents

Register JavaScript functions as tools and combine tools + prompt into agents.

defAgent(
    "git",
    "Query a repository using Git to accomplish tasks.",
    `Your are a helpful LLM agent that can use the git tools to query the current repository.
    Answer the question in QUERY.
    - The current repository is the same as github repository.`,
    { model, system: ["system.github_info"], tools: ["git"] }
)

then use it as a tool

script({ tools: "agent" })

$`Do a statistical analysis of the last commits`

🔍 RAG Built-in

Vector search.

const { files } = await retrieval.vectorSearch("cats", "**/*.md")

🐙 GitHub Models and GitHub Copilot

Run models through GitHub Models or GitHub Copilot.

script({ ..., model: "github:gpt-4o" })

💻 Local Models

Run your scripts with Open Source models, like Phi-3, using Ollama, LocalAI.

script({ ..., model: "ollama:phi3" })

🐍 Code Interpreter

Let the LLM run code in a sandboxed execution environment.

script({ tools: ["python_code_interpreter"] })

🐳 Containers

Run code in Docker containers.

const c = await host.container({ image: "python:alpine" })
const res = await c.exec("python --version")

🧩 LLM Composition

Run LLMs to build your LLM prompts.

for (const file of env.files) {
    const { text } = await runPrompt((_) => {
        _.def("FILE", file)
        _.$`Summarize the FILE.`
    })
    def("SUMMARY", text)
}
$`Summarize all the summaries.`

🅿️ Prompty support

Run your Prompty files as well!

⚙ Automate with CLI

Automate using the CLI, integrate reports in your CI/CD pipeline.

npx genaiscript run tlaplus-linter "*.tla"

💬 Pull Request Reviews

Integrate into your Pull Requests checks through comments, reviews, or description updates. Supports GitHub Actions and Azure DevOps pipelines.

npx genaiscript ... --pull-request-reviews

⭐ Tests and Evals

Build reliable prompts using tests and evals powered by promptfoo.

script({ ..., tests: {
  files: "penguins.csv",
  rubric: "is a data analysis report",
  facts: "The data refers about penguin population in Antarctica.",
}})

LLM friendly docs

If you are an LLM crawler, fetch https://microsoft.github.io/genaiscript/.well-known/llms.txt for an documentation map or add the .md suffix to any documentation URLs to get a raw markdown content.

For example, https://microsoft.github.io/genaiscript/guides/prompt-as-code.md (note the .md extension)
