Devin SDK reference

This section is generated from the TypeScript source of @cognition-ai/sdk and covers the hand-written SDK: the layer you use to run sessions.

Start from	For
`createDevin`	Getting a `CloudDevin` or `LocalDevin`
`CloudDevin`, `LocalDevin`	Creating, resuming, listing and attaching to sessions
`CloudSession`, `LocalSession`, `AcpSession`	`run()`, `send()`, `stream()`, `cancel()`, `events()` on a session
`SessionEvent`, `ToolCall`, `ToolCallDetail`	The typed events a turn yields and the normalized tool-call payload
`Turn`, `RunOptions`, `SessionOutcome`	What `run()` returns, including typed structured output
`prompt`	Building prompts with files, images and resources
`CognitionAcp`	Cognition’s ACP extension methods and types, for `extRequest()`
`Fusion`, `FusionModel`	Pairing a lead and sidekick model for a local session
`traceSessions`, `traceSession`	Tracing sessions with OpenTelemetry, from `@cognition-ai/sdk/tracing`

The API client that CloudDevin exposes as devin.api is documented separately under API client; its types show up here by name where an SDK signature uses them.
