Api quality

Define an agent with typed custom tools in a few lines of code C

Agent authoring

Checkpoint agent state so a run can resume exactly where it left off after a crash or restart C

Durable state

Pause an agent mid-run for human input or approval and resume with the human's decision C

Approval flows

Stream tokens and intermediate agent events (tool calls, steps) to my UI in real time C

Streaming

Swap the underlying LLM provider or model without rewriting my agent C

Portability

Trace every LLM call and tool invocation of an agent run in an observability UI C

Tracing

Attach input/output guardrails that validate, transform, or block unsafe content C

Guardrails

Orchestrate multiple agents — handoffs, subagents, or crews — inside one workflow C

Multi agent

Define rules that trigger actions automatically on events G

Get schema-validated structured output from an agent, with automatic retries when validation fails C

Structured output

Self-host the core product G

Export all of my data in open formats and leave G

Prevent my data from being used to train AI models G

Give agents long-term memory that persists across sessions and threads C

Memory

Require human approval before specific sensitive tool calls execute C

Approval flows

Run my agents entirely on my own infrastructure with no dependence on the vendor's platform C

Deployment

Compose agents into an explicit graph or workflow with branching, loops, and parallel steps C

Workflow control

Restrict what an agent may do with fine-grained tool permissions and sandboxed execution C

Guardrails

Deploy an agent to a managed runtime and call it as an API endpoint C

Deployment

Have a coding agent scaffold a new agent project from an official CLI or template in one command C

Ai buildability

Ai buildability

Memory

Opt out of telemetry and usage tracking G

Unit-test agents with mocked models and tools C

Testing

Version, review, and roll back my automations G
