I have just completed week three of the #BeSA program - Become a solutions architect - Designing with Strands agents
What did I learn
🧩 Strands Agents is AWS's open-source SDK for building production-ready AI agents in a few lines of code. The formula is simple: Model + Prompt + Tools. No complex workflow scaffolding. The LLM reasons, selects tools, and drives execution autonomously — already powering Amazon Q Developer and AWS Glue in production.
🔧 Turn any Python function into an agent tool with a single decorator. The @tool decorator is all it takes. The function's docstring becomes the model's instruction — it tells the LLM what the tool does and when to use it. Clean, minimal, and immediately practical.
🔁 The agentic loop is the core engine. Strands runs a continuous Think → Act → Observe → Reflect cycle until the task resolves. No manual orchestration. The model drives each iteration, deciding what to do next based on tool results — including replanning mid-execution when something unexpected comes back.
🤝 Multi-agent patterns are first-class primitives in Strands 1.0. Agents-as-Tools enables hierarchical delegation — an orchestrator agent calls specialist agents the same way it calls any other tool. Swarm and Graph patterns support parallel coordination and complex pipelines without bespoke glue code.
🌐 Model-agnostic by design. Swap between Amazon Bedrock, Anthropic, #OpenAI, #Meta Llama, #Ollama, or #LiteLLM in a single line. No rewriting agents. No framework lock-in. The architecture stays the same regardless of which model sits underneath.
🔭 Observability is built in, not bolted on. #OpenTelemetry support gives you full visibility into each reasoning step, tool call, and decision path. In production, you need to know not just what the agent did — but why. Strands makes that auditable by default.
🛠️ Built a multi-tool Strands agent from scratch in the hands-on workshop — wiring custom tools, running the agentic loop locally, and connecting to MCP servers. Watching the model reason through a multi-step task in real time — selecting tools, evaluating results, replanning — is where the architecture stops being abstract.
