memory - Memory & Knowledge

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.

memory_search

Search historical memory and knowledge base content with hybrid keyword and vector retrieval.

Parameter	Type	Required	Description
query	string	Yes	Search query

memory_get

Read the content of a specific memory or knowledge file.

Parameter	Type	Required	Description
path	string	Yes	Relative path to the file (e.g. MEMORY.md, memory/2026-01-01.md, knowledge/concepts/rag.md)
start_line	integer	No	Start line number
end_line	integer	No	End line number

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

<Note> When `knowledge` is set to `false` in config, the tool descriptions and search scope automatically adjust to include only memory files. </Note>
