## What it does

The skill hands your agent ready patterns for Amazon Bedrock on AWS SDK for Java 2.x. It covers client setup for `BedrockClient` and `BedrockRuntimeClient`, building model-specific JSON payloads for Claude, Titan and Llama, parsing the response, and streaming through `invokeModelWithResponseStream`.

There are examples for RAG embeddings, wiring generative AI into Spring Boot services, and retry logic with exponential backoff when Bedrock throttles you. The skill suggests testing with a simple prompt first to confirm model access and response parsing before you ship anything.

You need model access enabled in the AWS Console and IAM permissions for Bedrock — the skill recommends IAM roles over access keys. The examples pull in the `org.json` library, so add it to your dependencies. Model IDs are passed as strings like `anthropic.claude-sonnet-4-5-20250929-v1:0`, and an unknown prefix throws an exception, so check the identifier before running.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add giuseppe-trisciuoglio/developer-kit --skill aws-sdk-java-v2-bedrock -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/aws-sdk-java-v2-bedrock/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/aws-sdk-java-v2-bedrock/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add giuseppe-trisciuoglio/developer-kit --skill aws-sdk-java-v2-bedrock -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/aws-sdk-java-v2-bedrock/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add giuseppe-trisciuoglio/developer-kit --skill aws-sdk-java-v2-bedrock -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/aws-sdk-java-v2-bedrock/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install giuseppe-trisciuoglio/developer-kit aws-sdk-java-v2-bedrock
```

2. **Manually: put the files in place**
- File: `.github/skills/aws-sdk-java-v2-bedrock/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add giuseppe-trisciuoglio/developer-kit --skill aws-sdk-java-v2-bedrock -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/giuseppe-trisciuoglio/developer-kit --path plugins/developer-kit-java/skills/aws-sdk-java-v2-bedrock
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/aws-sdk-java-v2-bedrock/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add giuseppe-trisciuoglio/developer-kit --skill aws-sdk-java-v2-bedrock -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/giuseppe-trisciuoglio/developer-kit/tree/HEAD/plugins/developer-kit-java/skills/aws-sdk-java-v2-bedrock/SKILL.md

## When to use it
- call Claude or Titan from Java through Bedrock
- build a JSON payload for a specific model format
- stream a response and join the chunks
- create embeddings for document retrieval
- add generative AI to a Spring Boot service

## Example prompts
- show me how to invoke Claude with BedrockRuntimeClient in Java
- build a payload for amazon.titan with temperature 0.7
- add streaming Bedrock responses with retry on failure

# AWS SDK for Java 2.x - Amazon Bedrock

## Overview

Invokes foundation models through AWS SDK for Java 2.x. Configures clients, builds model-specific JSON payloads, handles streaming responses with error recovery, creates embeddings for RAG, integrates generative AI into Spring Boot applications, and implements exponential backoff for resilience.

## When to Use

- Invoke Claude, Llama, Titan, or Stable Diffusion for text/image generation
- Configure BedrockClient and BedrockRuntimeClient instances
- Build and parse model-specific payloads (Claude, Titan, Llama formats)
- Stream real-time AI responses with async handlers and error recovery
- Create embeddings for retrieval-augmented generation
- Integrate generative AI into Spring Boot microservices
- Handle throttling with exponential backoff retry logic

## Quick Start

### Dependencies

```xml
<!-- Bedrock (model management) -->
<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>bedrock</artifactId>
</dependency>

<!-- Bedrock Runtime (model invocation) -->
<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>bedrockruntime</artifactId>
</dependency>

<!-- For JSON processing -->
<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20231013</version>
</dependency>
```

### Client Setup

```java
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.bedrock.BedrockClient;
import software.amazon.awssdk.services.bedrockruntime.BedrockRuntimeClient;

// Model management client
BedrockClient bedrockClient = BedrockClient.builder()
    .region(Region.US_EAST_1)
    .build();

// Model invocation client
BedrockRuntimeClient bedrockRuntimeClient = BedrockRuntimeClient.builder()
    .region(Region.US_EAST_1)
    .build();
```
