## What it does
The plugin adds five specialists to Claude: a planner, a builder, a debugger, a prompt writer and a quality reviewer. Alongside them come more than forty slash commands covering project scaffolding, debugging, evaluation and credential management. A SessionStart hook pulls in the Output SDK conventions automatically, so the agent knows the framework before you type anything.
The framework itself is a TypeScript library for AI workflows. A workflow holds the deterministic coordination logic, steps do the I/O, prompts live in `.prompt` files with YAML frontmatter and Liquid templating, and evaluators use LLM-as-judge with confidence scores. Temporal runs underneath: retries with exponential backoff, workflow history, replay on failure. Credentials are encrypted with AES-256-GCM and scoped per environment and workflow.
Two things have to be in place first. Node.js 20+ and Docker Desktop — the local dev environment with Temporal will not come up without Docker. You also need an LLM API key, Anthropic for instance. Then `npx @outputai/cli init` scaffolds the project, and `npx output dev` starts Temporal, the API server, a worker with hot reload and the Temporal UI on port 8080.
## Install

## When to use it
- scaffold a new Output SDK project from scratch
- learn the framework conventions before writing a prompt
- debug a failed workflow run by its id
- write an LLM-as-judge evaluator with a confidence score
- keep API keys out of the codebase and away from the agent
## Example prompts
- scaffold a new Output project and lay out the workflow structure
- debug this workflow by id and show me which step failed
- write a quality evaluator for this workflow with a confidence score

The open-source TypeScript framework for building AI workflows and agents. Designed for Claude Code — describe what you want, Claude builds it, with all the best practices already in place.
One framework. Prompts, evals, tracing, cost tracking, orchestration, credentials. No SaaS fragmentation. No vendor lock-in. Everything in your codebase, everything your AI coding agent can reach.

## Why Output
Every piece of the AI stack is becoming a separate subscription. Prompts in one tool. Traces in another. Evals in a third. Cost tracking across five dashboards. None of them talk to each other. Half of them will get acquired or shut down before your product ships.
Output brings everything together. One TypeScript framework, extracted from thousands of production AI workflows. Best practices baked in so beginners ship professional code from day one, and experienced AI engineers stop rebuilding the same infrastructure.
### Build AI using AI
Output is the first framework designed for AI coding agents. The entire codebase is structured so Claude Code can scaffold, plan, generate, test, and iterate on your workflows. Every workflow is a folder — code, prompts, tests, evals, traces, all together. Your agent reads one folder and has full context.
### Own your prompts
`.prompt` files with YAML frontmatter and Liquid templating. Version-controlled, reviewable in PRs, deployed with your code. Switch providers by changing one line. No subscription needed to manage your own prompts.
### See everything that happens
Every LLM call, HTTP request, and step traced automatically. Token counts, costs, latency, full prompt/response pairs. JSON in `logs/runs/`. Zero config. Claude Code analyzes your traces and fixes issues — because the data is in your file system.
### Test AI like software
LLM-as-judge evaluators with confidence scores. Inline evaluators for production retry loops. Offline evaluators for dataset testing. Deterministic assertions and subjective quality judges.
### Use any model
Anthropic, OpenAI, Azure, Vertex AI, Bedrock. One API. Structured outputs, streaming, tool calling — all work the same regardless of provider.
### Scale without worrying
Temporal under the hood. Automatic retries with exponential backoff. Workflow history. Replay on failure. Child workflows. Parallel execution with concurrency control. You don't think about Temporal until you need it — then it's already there.
### Keep secrets secret
AI apps need a lot of API keys. Sharing `.env` files is risky, and coding agents shouldn't see your secrets. Output encrypts credentials with AES-256-GCM, scoped per environment and workflow, managed through the CLI. No external vault subscription needed.
## Quick Start
Requirements:
- [Node.js](https://nodejs.org/) 20+
- [Docker Desktop](https://www.docker.com/products/docker-desktop/)
- An LLM API key (e.g. [Anthropic](https://console.anthropic.com/))
Scaffold a project and add your API key to `.env` (`ANTHROPIC_API_KEY=sk-ant-...`):
```bash
npx @outputai/cli init
cd
```
