# SDK

Drive OpenCode from your own scripts, CI jobs and tools. The SDK runs OpenCode inside your process, with your config and models, and its typed client creates sessions, sends prompts and streams every event.

## Fix CI from code

A short script asks OpenCode to fix failing tests, then runs them again.

## Follow every step

Stream events to see each tool the agent calls, as it happens.

## Build your own tools

Wire OpenCode into bots, dashboards and workflows with a few lines.

## Features

- **TypeScript client:** Typed requests and events, the same values as @opencode/client.
- **Sessions from code:** Create sessions and send prompts from any script.
- **Any model:** Uses whichever models your OpenCode setup has.
- **npm or bun:** Install it with npm i @opencode/sdk or bun add @opencode/sdk.
- **In-process host:** Runs OpenCode in memory, with no network hop.
- **Your plugins:** Pass your own plugins in when you create the in-process host.
- **Promise or Effect:** A Promise API and an Effect API with the same values.
- **Cloudflare Workers:** Run OpenCode inside a Cloudflare Durable Object on Workers.

## Download

```bash
# npm
npm i @opencode/sdk

# bun

#### Zmiany niekompatybilne

**SDK: fewer endpoints wait for plugins to load**

On a Location that is still loading plugins, `agent.list` returns the agents loaded so far, and `integration.list`, `usage.limits`, `vcs.init`, `rpc.call` and `artifact.*` no longer wait up to 5 seconds. Entries and actions that a plugin provides appear when it finishes loading, so refresh on the matching `*.updated` event. Model, provider, `generate.*`, `voice.*` and `websearch.query` endpoints still wait.

#### Ulepszenia

- **SDK:** `credential.updated` includes the `integrationID` and `credentialID` of the login that changed. ([#62762](https://github.com/anomalyco/opencode/pull/62762))
- **SDK:** Predicate questions in `client.experimental.generate.decisions` accept optional `criteria: { true?, false? }`. ([#62819](https://github.com/anomalyco/opencode/pull/62819))
