You can write the following script: ```js $`Write a 'hello world' poem.` ``` The `$` function is a template tag that creates a prompt. The prompt is then sent to the LLM (you configured), which generates the poem. Let's make it more interesting by adding files, data and structured output. Say you want to include a file in the prompt, and then save the output in a file. You can write the following script: ```js // read files const file = await workspace.readText("data.txt") // include the file content in the prompt in a context-friendly way def("DATA", file) // the task $`Analyze DATA and extract data in JSON in data.json.` ``` The `def` function includes the content of the file, and optimizes it if necessary for the target LLM. GenAIScript script also parses the LLM output and will extract the `data.json` file automatically. --- ## 🚀 Quickstart Guide Get started quickly by installing the [Visual Studio Code Extension](https://microsoft.github.io/genaiscript/getting-started/installation/) or using the [command line](https://microsoft.github.io/genaiscript/getting-started/installation). --- ## ✨ Features ### 🎨 Stylized JavaScript & TypeScript Build prompts programmatically using [JavaScript](https://microsoft.github.io/genaiscript/reference/scripts/) or [TypeScript](https://microsoft.github.io/genaiscript/reference/scripts/typescript). ```js def("FILE", env.files, { endsWith: ".pdf" }) $`Summarize FILE. Today is ${new Date()}.` ``` --- ### 🚀 Fast Development Loop Edit, [Debug](https://microsoft.github.io/genaiscript/getting-started/debugging-scripts/), [Run](https://microsoft.github.io/genaiscript/getting-started/running-scripts/), and [Test](https://microsoft.github.io/genaiscript/getting-started/testing-scripts/) your scripts in [Visual Studio Code](https://microsoft.github.io/genaiscript/getting-started/installation) or with the [command line](https://microsoft.github.io/genaiscript/getting-started/installation). --- ### 🔗 Reuse and Share Scripts Scripts are [files](https://microsoft.github.io/genaiscript/reference/scripts/)! They can be versioned, shared, and forked. ```js // 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](https://microsoft.github.io/genaiscript/reference/scripts/schemas). Zod support builtin. ```js const data = defSchema("MY_DATA", { type: "array", items: { ... } }) $`Extract data from files using ${data} schema.` ``` --- ### 📄 Ingest Text from PDFs, DOCX, ... Manipulate [PDFs](https://microsoft.github.io/genaiscript/reference/scripts/pdf), [DOCX](https://microsoft.github.io/genaiscript/reference/scripts/docx), ... ```js def("PDF", env.files, { endsWith: ".pdf" }) const { pages } = await parsers.PDF(env.files[0]) ``` --- ### 📊 Ingest Tables from CSV, XLSX, ... Manipulate tabular data from [CSV](https://microsoft.github.io/genaiscript/reference/scripts/csv), [XLSX](https://microsoft.github.io/genaiscript/reference/scripts/xlsx), ... ```js 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. ```js $`Save the result in poem.txt.` ``` ```txt FILE ./poem.txt The quick brown fox jumps over the lazy dog. ``` --- ### 🔍 File Search Grep or fuzz search [files](https://microsoft.github.io/genaiscript/reference/scripts/files). ```js const { files } = await workspace.grep(/[a-z][a-z0-9]+/, { globs: "*.md" }) ``` --- ## Classify Classify text, images or a mix of all. ```js const joke = await classify( "Why did the chicken cross the road? To fry in the sun.", { yes: "funny", no: "not funny", } ) ``` ### LLM Tools Register JavaScript functions as [tools](https://microsoft.github.io/genaiscript/reference/scripts/tools) (with fallback for models that don't support tools). [Model Context Protocol (MCP) tools](https://microsoft.github.io/genaiscript/reference/scripts/mcp-tools) are also supported. ```js defTool( "weather", "query a weather web api", { location: "string" }, async (args) => await fetch(`https://weather.api.api/?location=${args.location}`) ) ``` --- ### LLM Agents Register JavaScript functions as **tools** and combine tools + prompt into agents. ```js 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 ```js script({ tools: "agent_git" }) $`Do a statistical analysis of the last commits` ``` See the [git agent source](https://github.com/microsoft/genaiscript/blob/main/packages/cli/genaisrc/system.agent_git.genai.mts). --- ### 🔍 RAG Built-in [Vector search](https://microsoft.github.io/genaiscript/reference/scripts/vector-search/). ```js const { files } = await retrieval.vectorSearch("cats", "**/*.md") ``` --- ### 🐙 GitHub Models and GitHub Copilot Run models through [GitHub Models](https://microsoft.github.io/genaiscript/configuration/github) or [GitHub Copilot](https://microsoft.github.io/genaiscript/configuration/github-copilot-chat). ```js script({ ..., model: "github:gpt-4o" }) ``` --- ### 💻 Local Models Run your scripts with [Open Source models](https://microsoft.github.io/genaiscript/getting-started/configuration/), like [Phi-3](https://azure.microsoft.com/en-us/blog/introducing-phi-3-redefining-whats-possible-with-slms/), using [Ollama](https://ollama.com/), [LocalAI](https://localai.io/). ```js script({ ..., model: "ollama:phi3" }) ``` --- ### 🐍 Code Interpreter Let the LLM run code in a sand-boxed execution environment. ```js script({ tools: ["python_code_interpreter"] }) ``` --- ### 🐳 Containers Run code in Docker [containers](https://microsoft.github.io/genaiscript/reference/scripts/container). ```js const c = await host.container({ image: "python:alpine" }) const res = await c.exec("python --version") ``` --- ### Video processing Transcribe and screenshot your videos so that you can feed them efficiently in your LLMs requests. ```js // transcribe const transcript = await transcript("path/to/audio.mp3") // screenshots at segments const frames = await ffmpeg.extractFrames("path_url_to_video", { transcript }) def("TRANSCRIPT", transcript) def("FRAMES", frames) ``` ### 🧩 LLM Composition [Run LLMs](https://microsoft.github.io/genaiscript/reference/scripts/inline-prompts/) to build your LLM prompts. ```js 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](https://prompty.ai) files as well! ```markdown --- name: poem --- Write me a poem ``` --- ### Pluggable Secret Scanning Scan your chats for secrets using [secret scanning](/genaiscript/reference/scripts/secret-scanning). ```json { "secretPatterns": { ..., "OpenAI API Key": "sk-[A-Za-z0-9]{32,48}" } } ``` ### ⚙ Automate with CLI or API Automate using the [CLI](https://microsoft.github.io/genaiscript/reference/cli) or [API](https://microsoft.github.io/genaiscript/reference/api). ```bash npx genaiscript run tlaplus-linter "*.tla" ``` ```js import { run } from "genaiscript/api" const res = await run("tlaplus-linter", "*.tla") ``` --- ### Safety First!
