Stabilize Managed Agent Memory with Updated Beta Headers
Switch to the latest Beta headers for stable agent memory.
Update your Claude API requests to use the 'agent-memory-2026-07-22' beta header to ensure stable memory listing and compatibility with the latest SDKs.
The Scenario
You are maintaining a Claude-powered agent that uses long-term memory, and you need to ensure your memory retrieval remains stable after the July 2026 API changes.
Before & after
Developers used the 'managed-agents-2026-04-01' header, which supported inconsistent 'order_by' parameters and complex path matching. Troubleshooting these inconsistencies could take hours of debugging.
Verify your SDK version (e.g., Python 0.116.0+) and update your code to use the 'agent-memory-2026-07-22' beta header for stable, server-defined sorting. This takes 5 minutes to update.
The Prompt
I am currently using the 'managed-agents-2026-04-01' beta header for Claude memory stores. Based on the July 2026 update, help me refactor my [PYTHON/TYPESCRIPT] code to use the 'agent-memory-2026-07-22' header and explain how my 'path_prefix' logic needs to change.
The new 'agent-memory-2026-07-22' beta header enforces a stable order and simplifies path matching (prefixes must end in '/'). If you are using updated SDKs, they may already send this header by default, so check for conflicts.
