The memory tool contains two sub-tools: memory_search (search memory) and memory_get (read memory or knowledge files).
When the knowledge base feature is enabled, both tools also support accessing files under the knowledge/ directory.
Dependencies
No extra dependencies, available by default. Managed by the Agent Core memory system.

How It Works
The Agent automatically invokes memory tools in these scenarios:
- When the user shares important information → stores to memory
- When historical context is needed → searches relevant memory
- When conversation reaches a certain length → extracts summary for storage
- When discussing domain knowledge → retrieves relevant pages from the knowledge base
When knowledge is set to false in config, the tool descriptions and search scope automatically adjust to include only memory files.
