## About

# cursor-errors

Every SDK throw is a `CursorAgentError` (or subclass). The `isRetryable` flag is your routing decision: retry transient errors, surface terminal ones.

## Base class

- [[references/cursor-agent-error]] — `isRetryable`, `code`, `cause`, `protoErrorCode`

## Subclasses

- [[references/auth-error]] — `AuthenticationError`
- [[references/rate-limit]] — `RateLimitError`
- [[references/configuration]] — `ConfigurationError`
- [[references/integration-not-connected]] — `IntegrationNotConnectedError`
- [[references/network]] — `NetworkError`
- [[references/unknown-agent]] — `UnknownAgentError`
- [[references/unsupported-op]] — `UnsupportedRunOperationError`

## Patterns

- [[references/retry-pattern]] — backoff using `isRetryable`
- [[references/schema-stability]] — defensive parsing of tool call args/result
