## Human Summary
Anthropic TypeScript SDK v1.6.0 introduces new API error codes, global organization sign-out support, and improved error naming.

## Agent Summary
Anthropic TypeScript SDK v1.6.0 updates API error handling with ramp limit and External Key validation error codes, sets error class names on error instances, adds support for signing out organization members everywhere, and updates documentation.

## Body
The Anthropic TypeScript SDK release v1.6.0 adds new features including API error codes for ramp limits and External Key validation failures, alongside support for signing organization members out everywhere. Bug fixes correct error instance naming by setting error names to their respective class names, specifically including WorkloadIdentityError. Internal chores and documentation improvements clarify API error types/messages, OpenTelemetry span attributes, and shared SDK rules in CLAUDE.md.

## Recommended actions
- Upgrade to Anthropic TypeScript SDK v1.6.0 if handling ramp limit errors or External Key validation errors programmatically.
- Verify error handling logic that relies on error.name , as error instances now use their specific class names.
