From a461464d52ff24583875e0a9e37231a47b0c240b Mon Sep 17 00:00:00 2001 From: Roo Code Date: Wed, 30 Jul 2025 15:14:12 +0000 Subject: [PATCH] feat: enable prompt caching for AWS Bedrock Application Inference Profiles - Add manual prompt caching configuration for Application Inference Profiles - Add UI controls for configuring cache parameters (max cache points, min tokens, cachable fields) - Update provider settings schema with new manual cache configuration fields - Enhance ARN parsing to support async inference profile model ID resolution - Add comprehensive tests for manual prompt caching functionality - Maintain backward compatibility with existing automatic cache detection Fixes #6429 --- packages/types/src/provider-settings.ts | 5 + .../bedrock-manual-prompt-cache.spec.ts |
