bedrock

AWS Bedrock — enterprise path for Claude on Anthropic's hosted-on-AWS surface.

import { bedrock } from '@agentskit/adapters'

const adapter = bedrock({
  model: 'anthropic.claude-3-5-sonnet-20241022-v2:0',
  region: 'us-east-1',
})

@aws-sdk/client-bedrock-runtime is an optional peer dependency — the adapter loads it lazily so installs without AWS infra keep working.

npm install @aws-sdk/client-bedrock-runtime

Auth uses the AWS SDK's default credential chain — env vars, shared config, IAM role, SSO. No credentials are read or stored by the adapter itself.

#Options

Option	Type	Default
`model`	`string`	required (must start with `anthropic.`)
`region`	`string`	SDK default (env / shared config)
`maxTokens`	`number`	`4096`
`client`	`BedrockRuntimeClientLike`	constructed from `region`

#Capabilities

{ streaming: true, tools: true, multiModal: true, usage: true, reasoning: model.includes('sonnet' | 'opus') }.

Streams via InvokeModelWithResponseStreamCommand. Tool calls follow the Anthropic-on-Bedrock event shape (content_block_start / content_block_delta / content_block_stop).

#Caveats

Optional peer dep. If @aws-sdk/client-bedrock-runtime is not installed, the adapter throws a friendly install hint on the first request.
v1 only routes Anthropic models. Titan and other foundation models on Bedrock are tracked as a follow-up.
Guardrails are not wired in v1. Plan to add in Phase 2.
Knowledge Bases belong in @agentskit/rag.

#Env

Var	Purpose
`AWS_REGION`	Default region for the SDK
`AWS_ACCESS_KEY_ID` / `AWS_SECRET_ACCESS_KEY`	Static credentials (or use IAM role / SSO)
