[ineffyble]

Target Component

External Integrations (LLM/Search APIs)

Enhancement Description

It would be great if PentAGI supported Anthropic Workload Identity Federation, removing the need for long-lived API credentials for the Anthropic provider.

Technical Details

This would need to be implemented in the vxcontrol fork of langchaingo.
