Fundamental SDK usage patterns
The basic demo shows how to create a Claude client, run prompts, and handle responses with structured output.
Key Features:
- Creating a Claude client
- Running simple prompts
- Configuring RunOptions
- Accessing structured results
Run it: just demo basic
Real-time message streaming
Stream responses as they're generated for responsive applications. Handle different message types and implement graceful cancellation.
Key Features:
- StreamPrompt for real-time responses
- Message type handling (system, assistant, result)
- Error channel processing
- Context cancellation support
Run it: just demo streaming
Session management and conversation forking
Manage multi-turn conversations with explicit session IDs. Fork conversations to explore alternative paths while preserving the original.
Key Features:
- Explicit session ID management
- Resume previous conversations
- Fork sessions for branching
- Ephemeral (non-persisted) sessions
Run it: just demo sessions
Model Context Protocol integration
Extend Claude's capabilities with MCP servers. Configure HTTP, SSE, and Stdio servers for external tool integration.
Key Features:
- MCPConfigBuilder fluent API
- HTTP, SSE, and Stdio server types
- Environment variable injection
- Multiple config file support
Run it: just demo mcp
Automatic retry with exponential backoff
Handle transient failures gracefully with configurable retry policies. Exponential backoff with jitter prevents thundering herd problems.
Key Features:
- Configurable retry attempts
- Exponential backoff
- Jitter for distributed systems
- Retryable error detection
Run it: just demo retry
Fine-grained tool access control
Control which tools Claude can use with permission modes, whitelists, and custom callbacks. Essential for production security.
Key Features:
- Permission modes (Default, AcceptEdits, Bypass)
- AllowedTools and DisallowedTools lists
- Pre-built callbacks (ReadOnly, SafeBash, FilePath)
- Custom permission callbacks
Run it: just demo permissions
Cost tracking and budget limits
Track API costs across requests and enforce spending limits. Essential for cost-conscious production deployments.
Key Features:
- Per-request budget limits (MaxBudgetUSD)
- Shared BudgetTracker across requests
- Real-time cost monitoring
- Budget exceeded detection
Run it: just demo budget
Plugin system extensibility
Extend SDK behavior with plugins for logging, metrics, filtering, and auditing. Create custom plugins for specialized needs.
Key Features:
- Built-in plugins (Logging, Metrics, ToolFilter, Audit)
- Plugin lifecycle hooks (BeforeRun, AfterRun)
- Plugin manager for enable/disable
- Custom plugin interface
Run it: just demo plugins
Agent orchestration for complex tasks
Orchestrate specialized AI agents for complex multi-step tasks. Decompose work into exploration, planning, and execution phases.
Key Features:
- Subagent types (Explore, Plan, Code, Review)
- Task decomposition patterns
- Agent orchestration workflows
- Parallel execution support
Run it: just demo subagents
