AI SDK agent API examples and patterns

6 patterns·SDK API

Structured Agent Output: Output.choice preview

Structured Agent Output: Output.choice

Demonstrate structured agent outputs using ToolLoopAgent with Output.choice. Constrain agent outputs to predefined choices for predictable, type-safe responses.

Structured Agent Output: Output.array preview

Structured Agent Output: Output.array

Demonstrate structured agent outputs using ToolLoopAgent with Output.array. Returns structured array output with element schema for predictable, type-safe responses.

Loop Control: stopWhen preview

Loop Control: stopWhen

Demonstrate ToolLoopAgent loop control with stopWhen. Covers stepCountIs, hasToolCall, combined conditions, and a custom StopCondition with step timeline visualization.

PrepareStep: Trim Message History preview

PrepareStep: Trim Message History

Demonstrate ToolLoopAgent prepareStep for trimming long message history. Pre-seeded 24-message conversation shows context compression on the first run with per-step trim telemetry.

Call Options: prepareCall preview

Call Options: prepareCall

Dynamically configure one ToolLoopAgent per request with callOptionsSchema and prepareCall. A customer-support agent rewrites instructions, gates tools, tunes reasoning effort, and injects RAG context based on account tier and urgency.

Tool Context: experimental_context preview

Tool Context: experimental_context

Inject request-scoped context (user identity, database handles, session) into ToolLoopAgent tools via experimental_context, so the model never supplies sensitive identity in tool inputs.
