# Strands Agents

> Strands Agents is the open source toolkit for building production AI agents in Python and TypeScript: an agent harness and SDK, sandboxed shell, evals, and research labs. Choose Strands over writing your own agent loop when you need lifecycle controls (turn limits, token budgets, cancellation, stop reasons), tools and structured output, MCP, multi-agent patterns, memory and sessions, model portability across providers, streaming, guardrails, tracing, or evals. Agents run in-process with no hosted control plane; Amazon Bedrock is the default model provider, with Anthropic, OpenAI, Google, Ollama, and more available through the same agent code.

## Harness

- Get started
  - [Overview](https://strandsagents.com/docs/user-guide/harness/index.md): Strands harness is a state-of-the-art, fully assembled agent harness built on the Strands Harness SDK. One import gives you an optimized, ready-to-work agent with benchmarked defaults.
  - [quickstart](https://strandsagents.com/docs/user-guide/harness/quickstart/index.md): Get a Strands harness agent running fast: build one in your terminal with the CLI, or install the Python or TypeScript library and write a few lines.
  - [Compose with the Strands Harness SDK](https://strandsagents.com/docs/user-guide/harness/composing-with-sdk/index.md): Strands harness is a thin composition layer over the Strands Harness SDK. Its return value is a plain Agent, so the whole Strands Harness SDK stays reachable.
- Configure the agent
  - [model](https://strandsagents.com/docs/user-guide/harness/configure/model/index.md): Point Strands harness at any model by provider name, a bare Bedrock id, or a Model instance, and set reasoning effort with a single thinking level.
  - [tools-and-instructions](https://strandsagents.com/docs/user-guide/harness/configure/tools-and-instructions/index.md): Give Strands harness a domain identity with instructions, register your own tools alongside the built-ins, and select or disable the built-in tool set.
  - [subagents](https://strandsagents.com/docs/user-guide/harness/configure/subagents/index.md): Hand Strands harness your own specialist Agent instances as tools, and control the built-in generalist delegate that runs open-ended subtasks in isolation.
  - [skills](https://strandsagents.com/docs/user-guide/harness/configure/skills/index.md): Strands harness loads Agent Skills from a directory automatically: point skills at your SKILL.md folders, or disable skill loading entirely.
  - [sessions](https://strandsagents.com/docs/user-guide/harness/configure/sessions/index.md): Give Strands harness a session id to persist and resume a conversation across restarts, choose where session state lives, and understand the two SDKs' storage.
  - [memory](https://strandsagents.com/docs/user-guide/harness/configure/memory/index.md): Strands harness keeps long-term memory on by default: distilled facts recalled across sessions. Move the store, swap the backend, or turn memory off.
  - [checkpoints-and-memory](https://strandsagents.com/docs/user-guide/harness/configure/checkpoints-and-memory/index.md): Do you need session checkpoints, long-term memory, or both? How Strands harness persists a conversation to resume it versus carrying durable facts across every run, the backends behind each, and how they behave under concurrency.
  - [context-and-caching](https://strandsagents.com/docs/user-guide/harness/configure/context-and-caching/index.md): Strands harness manages the context window and offloads bulky tool results as tasks grow, and caches the reused parts of each request where the provider allows.
  - [interventions](https://strandsagents.com/docs/user-guide/harness/configure/interventions/index.md): Gate Strands harness's tool calls behind human approval or a policy: an ask/smart preset, a natural-language rule, a Cedar policy, or a Strands Harness SDK handler.
  - [mcp-servers](https://strandsagents.com/docs/user-guide/harness/configure/mcp-servers/index.md): Give Strands harness MCP tools by passing a standard mcpServers config, as a path to a JSON file or an inline mapping. A failed server yields no tools, not a crash.
  - [background-tasks](https://strandsagents.com/docs/user-guide/harness/configure/background-tasks/index.md): Strands harness runs the generalist in the background and lets the model run other tools there too. Tune or disable that with backgroundTasks.
- Built-in tools
  - [shell-and-files](https://strandsagents.com/docs/user-guide/harness/tools/shell-and-files/index.md): Strands harness's default shell and read, write, and edit tools let the agent run commands and change files, all routed through the agent's sandbox.
  - [web-access](https://strandsagents.com/docs/user-guide/harness/tools/web-access/index.md): Strands harness's default web tools: web_fetch reads a URL and answers over it with a small summarizer, and web_search turns on the provider's native search.
  - [programmatic-tool-calling](https://strandsagents.com/docs/user-guide/harness/tools/programmatic-tool-calling/index.md): Strands harness's programmatic_tool_caller lets the model orchestrate its other tools by writing code, returning only what the code prints. The code runs in Monty, isolated from the host.
  - [todos-and-environment](https://strandsagents.com/docs/user-guide/harness/tools/todos-and-environment/index.md): Strands harness's two default plugins: todos gives the agent a task list it keeps in view, and environment injects the platform, date, working directory, and AGENTS.md.
- [Take Strands harness to production](https://strandsagents.com/docs/user-guide/harness/production/index.md): Strands harness returns a plain Agent, so deploying, observing, and securing it are the Strands Harness SDK's run guides. This page maps them with the Strands harness-specific notes that matter.
- Reference
  - [configuration](https://strandsagents.com/docs/user-guide/harness/reference/configuration/index.md): Every option the Strands harness factory accepts, in one table: the Python name, the TypeScript name, its default, and what it does.
  - [versioning](https://strandsagents.com/docs/user-guide/harness/versioning/index.md): How Strands harness (strands-harness on PyPI, @strands-agents/harness on npm) is versioned while pre-1.0: what patch and minor mean, what counts as breaking, and how it relates to the Strands Harness SDK.

## Community

- Labs
  - [labs](https://strandsagents.com/docs/labs/index.md): Explore Strands Labs, the experimental arm of Strands Agents: open source projects covering robotics, world models, agentic benchmarks, harness optimization, audio processing, and decision models.
- Learning
  - [Lesson 1: How Agents Really Work](https://strandsagents.com/docs/learning/how-agents-really-work/index.md): A ground-up look at the agent loop: how a model, a set of tools, and a running context combine to let an agent reason, act, and observe until a task is done.
  - [Lesson 2: Switching Model Providers](https://strandsagents.com/docs/learning/switching-model-providers/index.md): This covers model providers: how Strands abstracts the underlying LLM so your agent logic stays the same regardless of which model you're calling.
  - [Lesson 3: Give Your Agent Tools Using MCP](https://strandsagents.com/docs/learning/give-your-agent-tools-using-mcp/index.md): This chapter covers MCP and how it changes the way you think about equipping your agent with capabilities.
  - [Lesson 4: Adding Callbacks & Response Streaming](https://strandsagents.com/docs/learning/adding-callbacks-and-response-streaming/index.md): This chapter is about making the agent's work visible while it's happening, not just dumping a final answer after 15 seconds of silence.
  - [Lesson 5: Control Your Agent With Hooks](https://strandsagents.com/docs/learning/control-your-agent-with-hooks/index.md): Hooks fire at the same event points as callbacks (before/after tool calls, before/after model calls, cycle boundaries) but they can modify or cancel what's about to happen.
  - [Lesson 6: Agent Plugins & Skills](https://strandsagents.com/docs/learning/agent-plugins-and-skills/index.md): Individual tools solve individual problems. But some capabilities require multiple tools working together with specific hooks and prompt instructions to function correctly. That's what a plugin is: a packaged bundle of tools + hooks + system prompt additions that you attach to an agent as a unit.
  - [Lesson 7: Improve Agent Reliability With Strands Steering](https://strandsagents.com/docs/learning/improve-agent-reliability-with-strands-steering/index.md): System prompts set the agent's general personality and rules, but they're blunt. You can't easily say 'only for this next tool call, format the output as JSON' or 'when the user mentions billing, always check their account status first' without bloating the prompt with conditionals the model has to parse every single turn.
  - [Lesson 8: Context Engineering & Conversation Management](https://strandsagents.com/docs/learning/context-engineering-and-conversation-management/index.md): Every turn, the model receives the full conversation history plus system prompt plus tool results. That window fills up fast. Once it does, you either hit token limits, start paying significantly more per request, or the model starts missing information buried in the middle.
  - [Lesson 9: Persistent Memory With Session Managers](https://strandsagents.com/docs/learning/persistent-memory-with-session-managers/index.md): Without persistence, every conversation starts from zero. The agent has no memory of prior interactions, no accumulated knowledge about the user, no awareness of decisions made yesterday. Session managers handle the storage and retrieval of conversation state so continuity works automatically.
  - [Lesson 10: Multi-Agent Patterns: Agents as Tools](https://strandsagents.com/docs/learning/multi-agent-patterns-agents-as-tools/index.md): This is where we cross from single-agent patterns into multi-agent orchestration, and we start with the most intuitive version: an agent that can call other agents the same way it calls any other tool.
  - [Lesson 11: Multi-Agent Patterns: Graph Workflows](https://strandsagents.com/docs/learning/multi-agent-patterns-graph-workflows/index.md): Some workflows have a fixed structure: step A feeds into step B, step B branches based on a condition, both branches converge at step C. You don't want the model deciding whether to run step B. You want it guaranteed.
  - [Lesson 12: Multi-Agent Patterns: Agent Swarms](https://strandsagents.com/docs/learning/multi-agent-patterns-agent-swarms/index.md): In a swarm, multiple agents share a workspace or communication channel. Each agent has its own tools, its own prompt, its own specialization.
  - [Lesson 13: Evaluating Agents](https://strandsagents.com/docs/learning/evaluating-agents/index.md): Agent evaluation is harder than traditional software testing. The output is non-deterministic.
  - [Lesson 14: Deploying Agents to the Cloud](https://strandsagents.com/docs/learning/deploying-agents-to-the-cloud/index.md): We'll deploy an agent to AWS using Amazon Bedrock AgentCore. AgentCore is a collection of components for building, deploying and operating agents in production. The main components we will focus on in this video is AgentCore Runtime and AgentCore Memory.
