+# Managed Agents — Go
+
+> **Bindings not shown here:** This README covers the most common managed-agents flows for Go. If you need a class, method, namespace, field, or behavior that isn't shown, WebFetch the Go SDK repo **or the relevant docs page** from `shared/live-sources.md` rather than guess. Do not extrapolate from cURL shapes or another language's SDK.
+
+> **Agents are persistent — create once, reference by ID.** Store the agent ID returned by `agents.New` and pass it to every subsequent `sessions.New`; do not call `agents.New` in the request path. The Anthropic CLI is one convenient way to create agents and environments from version-controlled YAML — its URL is in `shared/live-sources.md`. The examples below show in-code creation for completeness; in production the create call belongs in setup, not in the request path.
+
+## Installation
+
+```bash
+go get github.com/anthropics/anthropic-sdk-go
+```
+
+## Client Initialization
+
+```go
+import (
+    "context"
+
+    "github.com/anthropics/anthropic-sdk-go"
+    "github.com/anthropics/anthropic-sdk-go/option"
+)
+
+// Default (uses ANTHROPIC_API_KEY env var)
+client := anthropic.NewClient()
+
+// Explicit API key
+client := anthropic.NewClient(
+    option.WithAPIKey("your-api-key"),
+)
+
+ctx := context.Background()
+```
+
+---
+
+## Create an Environment
+
+```go
+environment, err := client.Beta.Environments.New(ctx, anthropic.BetaEnvironmentNewParams{
+    Name: "my-dev-env",
+    Config: anthropic.BetaCloudConfigParams{
+        Networking: anthropic.BetaCloudConfigParamsNetworkingUnion{
+            OfUnrestricted: &anthropic.UnrestrictedNetworkParam{},
+        },
+    },
+})
+if err != nil {
+    panic(err)
+}
+fmt.Println(environment.ID) // env_...
+```
+
+---
+
+## Create an Agent (required first step)
+
+> ⚠️ **There is no inline agent config.** `Model`/`System`/`Tools` live on the agent object, not the session. Always start with `Beta.Agents.New()` — the session only takes `Agent: anthropic.BetaSessionNewParamsAgentUnion{OfString: anthropic.String(agent.ID)}` (or the typed `OfBetaManagedAgentsAgents` variant when you need a specific version).
+
+### Minimal
+
+```go
+// 1. Create the agent (reusable, versioned)
+agent, err := client.Beta.Agents.New(ctx, anthropic.BetaAgentNewParams{
+    Name: "Coding Assistant",
+    Model: anthropic.BetaManagedAgentsModelConfigParams{
+        ID:   "claude-opus-4-6",
+        Type: anthropic.BetaManagedAgentsModelConfigParamsTypeModelConfig,
+    },
+    System: anthropic.String("You are a helpful coding assistant."),
+    Tools: []anthropic.BetaAgentNewParamsToolUnion{{
+        OfAgentToolset20260401: &anthropic.BetaManagedAgentsAgentToolset20260401Params{
+            Type: anthropic.BetaManagedAgentsAgentToolset20260401ParamsTypeAgentToolset20260401,
+        },
+    }},
+})
+if err != nil {
+    panic(err)
+}
+
+// 2. Start a session
+session, err := client.Beta.Sessions.New(ctx, anthropic.BetaSessionNewParams{
+    Agent: anthropic.BetaSessionNewParamsAgentUnion{
+        OfBetaManagedAgentsAgents: &anthropic.BetaManagedAgentsAgentParams{
+            Type:    anthropic.BetaManagedAgentsAgentParamsTypeAgent,
+            ID:      agent.ID,
+            Version: anthropic.Int(agent.Version),
+        },
+    },
+    EnvironmentID: environment.ID,
+    Title:         anthropic.String("Quickstart session"),
+})
+if err != nil {
+    panic(err)
+}
+fmt.Printf("Session ID: %s, status: %s\n", session.ID, session.Status)
+```
+
+### Updating an Agent
+
+Updates create new versions; the agent object is immutable per version.
+
+```go
+updatedAgent, err := client.Beta.Agents.Update(ctx, agent.ID, anthropic.BetaAgentUpdateParams{
+    Version: agent.Version,
+    System:  anthropic.String("You are a helpful coding agent. Always write tests."),
+})
+if err != nil {
+    panic(err)
+}
+fmt.Printf("New version: %d\n", updatedAgent.Version)
+
+// List all versions
+iter := client.Beta.Agents.Versions.ListAutoPaging(ctx, agent.ID, anthropic.BetaAgentVersionListParams{})
+for iter.Next() {
+    version := iter.Current()
+    fmt.Printf("Version %d: %s\n", version.Version, version.UpdatedAt.Format(time.RFC3339))
+}
+if err := iter.Err(); err != nil {
+    panic(err)
+}
+
+// Archive the agent
+_, err = client.Beta.Agents.Archive(ctx, agent.ID, anthropic.BetaAgentArchiveParams{})
+if err != nil {
+    panic(err)
+}
+```
+
+---
+
+## Send a User Message
+
+```go
+_, err = client.Beta.Sessions.Events.Send(ctx, session.ID, anthropic.BetaSessionEventSendParams{
+    Events: []anthropic.SendEventsParamsUnion{{
+        OfUserMessage: &anthropic.BetaManagedAgentsUserMessageEventParams{
+            Type: anthropic.BetaManagedAgentsUserMessageEventParamsTypeUserMessage,
+            Content: []anthropic.BetaManagedAgentsUserMessageEventParamsContentUnion{{
+                OfText: &anthropic.BetaManagedAgentsTextBlockParam{
+                    Type: anthropic.BetaManagedAgentsTextBlockTypeText,
+                    Text: "Review the auth module",
+                },
+            }},
+        },
+    }},
+})
+if err != nil {
+    panic(err)
+}
+```
+
+> 💡 **Stream-first:** Open the stream *before* (or concurrently with) sending the message. The stream only delivers events that occur after it opens — stream-after-send means early events arrive buffered in one batch. See [Steering Patterns](../../shared/managed-agents-events.md#steering-patterns).
+
+---
+
+## Stream Events (SSE)
+
+```go
+// Open the stream first, then send the user message
+stream := client.Beta.Sessions.Events.StreamEvents(ctx, session.ID, anthropic.BetaSessionEventStreamParams{})
+defer stream.Close()
+
+if _, err := client.Beta.Sessions.Events.Send(ctx, session.ID, anthropic.BetaSessionEventSendParams{
+    Events: []anthropic.SendEventsParamsUnion{{
+        OfUserMessage: &anthropic.BetaManagedAgentsUserMessageEventParams{
+            Type: anthropic.BetaManagedAgentsUserMessageEventParamsTypeUserMessage,
+            Content: []anthropic.BetaManagedAgentsUserMessageEventParamsContentUnion{{
+                OfText: &anthropic.BetaManagedAgentsTextBlockParam{
+                    Type: anthropic.BetaManagedAgentsTextBlockTypeText,
+                    Text: "Summarize the repo README",
+                },
+            }},
+        },
+    }},
+}); err != nil {
+    panic(err)
+}
+
+events:
+for stream.Next() {
+    switch event := stream.Current().AsAny().(type) {
+    case anthropic.BetaManagedAgentsAgentMessageEvent:
+        for _, block := range event.Content {
+            fmt.Print(block.Text)
+        }
+    case anthropic.BetaManagedAgentsAgentToolUseEvent:
+        fmt.Printf("\n[Using tool: %s]\n", event.Name)
+    case anthropic.BetaManagedAgentsSessionStatusIdleEvent:
+        break events
+    case anthropic.BetaManagedAgentsSessionErrorEvent:
+        fmt.Printf("\n[Error: %s]\n", event.Error.Message)
+        break events
+    }
+}
+if err := stream.Err(); err != nil {
+    panic(err)
+}
+```
+
+### Reconnecting and Tailing
+
+When reconnecting mid-session, list past events first to dedupe, then tail live events:
+
+```go
+stream := client.Beta.Sessions.Events.StreamEvents(ctx, session.ID, anthropic.BetaSessionEventStreamParams{})
+defer stream.Close()
+
+// Stream is open and buffering. List history before tailing live.
+seenEventIDs := map[string]struct{}{}
+history := client.Beta.Sessions.Events.ListAutoPaging(ctx, session.ID, anthropic.BetaSessionEventListParams{})
+for history.Next() {
+    seenEventIDs[history.Current().ID] = struct{}{}
+}
+if err := history.Err(); err != nil {
+    panic(err)
+}
+
+// Tail live events, skipping anything already seen
+tail:
+for stream.Next() {
+    event := stream.Current()
+    if _, seen := seenEventIDs[event.ID]; seen {
+        continue
+    }
+    seenEventIDs[event.ID] = struct{}{}
+    switch event := event.AsAny().(type) {
+    case anthropic.BetaManagedAgentsAgentMessageEvent:
+        for _, block := range event.Content {
+            fmt.Print(block.Text)
+        }
+    case anthropic.BetaManagedAgentsSessionStatusIdleEvent:
+        break tail
+    }
+}
+if err := stream.Err(); err != nil {
+    panic(err)
+}
+```
