Overview

This skill provides a concise guide to building model-agnostic AI agents using the Strands Agents SDK. It explains installation, core APIs, ReAct patterns, multi-agent orchestration, streaming, and memory features. Use it to prototype or productionize agents on AWS, Bedrock, or any LLM endpoint.

How this skill works

Strands exposes an Agent abstraction plus tool definitions that let you register callable tools (decorator or class style) and wire them into an LLM-driven agent. You configure models by name or custom endpoint, choose a reasoning strategy like ReAct, and optionally plug in memory and streaming. For multi-agent workflows, a MultiAgentOrchestrator routes tasks between specialist agents and aggregates results.

When to use it

• Developing model-agnostic agents that must run with OpenAI, Anthropic, Bedrock, or custom LLMs.
• Implementing ReAct-style agents that interleave reasoning and tool calls for multi-step tasks.
• Building multi-agent systems with role-based specialists and orchestration strategies.
• Creating production agents that integrate with AWS services (AgentCore, CloudWatch, Bedrock).
• Streaming long responses or maintaining conversational and semantic memory across calls.

Best practices

• Define tools with clear parameter schemas and descriptions (decorator or Tool class) so the agent can call them reliably.
• Limit ReAct iterations and enable verbose mode during development to inspect reasoning steps.
• Use ConversationMemory for short-term context and SemanticMemory with embeddings for long-term facts.
• Isolate specialist agents with focused system prompts and tools, then orchestrate them with a routing strategy.
• Prefer streaming for UX-sensitive flows and test with the target LLM to tune latency and chunk sizes.

Example use cases

• Customer support agent that queries product DB, fetches tickets, and drafts replies using a writer agent.
• Incident response system where monitoring, research, and remediation agents collaborate via an orchestrator.
• Analytics pipeline: researcher pulls data, analyst computes metrics and visualizations, writer generates reports.
• Cloud operations tool that invokes AgentCore tools to query CloudWatch metrics and recommend actions.
• Interactive demos that stream model outputs while retaining user context across sessions.
