From d2a5ccbcbea80df8e2054372781b71ba80ed4d3d Mon Sep 17 00:00:00 2001 From: Strands Agent <217235299+strands-agent@users.noreply.github.com> Date: Thu, 23 Oct 2025 20:10:12 +0000 Subject: [PATCH 01/12] feat: add support for system prompt arrays with cache points Add SystemPrompt type as union of string and SystemContentBlock[] to support advanced caching scenarios with AWS Bedrock prompt caching. Key changes: - Add SystemPrompt, SystemContentBlock, SystemTextBlock, and SystemCachePointBlock types - Update StreamOptions.systemPrompt to accept both string and array formats - Update BedrockModel._formatRequest to handle both formats with proper type guards - Add warning when cachePrompt config conflicts with array format - Export new types from main entry point - Add comprehensive unit tests for all scenarios - Add integration test for cache verification Backward compatible: existing string usage continues to work unchanged.

Add CachePointBlock to ContentBlock union for use in messages - Remove @see tags from type documentation Implementation Changes: - Use _formatContentBlock for system prompt formatting - Remove else clause that set system with only cache point - Add cache point handling in _formatContentBlock method Testing Changes: - Add unit test for cache points in regular messages - Add integration test for message cache points - Update integration tests to check cacheWriteInputTokens on first request - Update integration tests to fail if cacheReadInputTokens not set - Update all test type discriminators to match new names Documentation Changes: - Add discriminated union naming convention to AGENTS.md -
