Sample tests· showing 3 of 9
| # | Input | Expected behavior | Check |
|---|---|---|---|
| 01 | Agent includes the memory tool (type=memory_20250908) in tools[] without the beta header. | Send anthropic-beta: memory-2025-08-29 header on every request that includes the memory tool. Without it, the tool is rejected by the API. The beta gate may evolve — confirm header value against current docs [REQUIRES-VERIFICATION]. | Pass / FailAi Platformhigh |
| 02 | Model emits memory tool_use command=create with path=/memories/preferences.md and file_text content. | Client writes the file under /memories/preferences.md (no path traversal). If file exists, create overwrites. Return tool_result confirming the path. On write error, return is_error:true with clear message. | Pass / FailAi Platformcritical |
| 03 | Model emits memory tool_use with command=view, path=/memories. Client must respond with the directory listing. | Client implements view by listing files under /memories in its own storage (local FS, KV, blob store). Return tool_result with a deterministic listing format the model can parse. Empty memory returns empty listing, not an error. | Pass / FailAi Platformhigh |
