Standardize AI Agent Memory Retrieval with Stable Ordering Beta Headers
Implement the agent-memory-2026-07-22 header for stable, predictable memory storage results.
Switch to the latest Claude beta header to ensure memory retrieval is ordered by the server, simplifying pagination and path prefixing.
The Scenario
You are building a production-grade AI agent that needs to reliably list and paginate through thousands of stored 'memory' files without missing entries due to unstable sorting.
Before & after
Developers previously handled inconsistent memory ordering and complex path matching manually, often requiring custom sorting logic that took 30–60 minutes to debug.
Using the new beta header `agent-memory-2026-07-22`, you can implement stable pagination with standardized depth and path parameters in about 5–10 minutes.
The Prompt
Update my Claude API request for listing memories to use the latest beta standards: Header: Anthropic-Beta: agent-memory-2026-07-22 Method: GET /v1/memory_stores/[MEMORY_STORE_ID]/memories Requirements: 1. Remove 'order_by' and 'order' parameters. 2. Ensure 'path_prefix' ends with '/'. 3. Set 'depth' to [0_OR_1]. Help me refactor this Python/TypeScript snippet: [PASTE_CODE_HERE]
The new beta header `agent-memory-2026-07-22` replaces `managed-agents-2026-04-01`. It enforces a stable, server-defined order for memory retrieval, simplifies the 'depth' parameter to 0 or 1, and requires 'path_prefix' to end with a slash for exact segment matching.
