-subtitle: Built-in tools for memory management and user communication
-slug: guides/agents/base-tools
----
-
-Base tools are built-in tools that enable memory management, user communication, and access to conversation history and archival storage.
-
-## Available Base Tools
-
-| Tool | Purpose |
-|------|---------|
-| `memory_insert` | Insert text into a memory block |
-| `memory_replace` | Replace specific text in a memory block |
-| `memory_rethink` | Completely rewrite a memory block |
-| `memory_finish_edits` | Signal completion of memory editing |
-| `conversation_search` | Search prior conversation history |
-| `archival_memory_insert` | Add content to archival memory |
-| `archival_memory_search` | Search archival memory |
-| `send_message` | Send a message to the user (legacy architectures only) |
-
-## Memory Block Editing
-
-Memory blocks are editable sections in the agent's context window. These tools let agents update their own memory.
-
-See the [Memory Blocks guide](/guides/agents/memory-blocks) for more about how memory blocks work.
-
-### memory_insert
-
-Insert text at a specific line in a memory block.
-
-**Parameters:**
-- `label`: Which memory block to edit
-- `new_string`: Text to insert
-- `insert_line`: Line number (0 for beginning, -1 for end)
-
-**Common uses:**
-- Add new information to the end of a block
-- Insert context at the beginning
-- Add items to a list
-
-### memory_replace
-
-Replace specific text in a memory block.
-
-**Parameters:**
-- `label`: Which memory block to edit
-- `old_string`: Exact text to find and replace
-- `new_string`: Replacement text
-
-**Common uses:**
-- Update outdated information
-- Fix typos or errors
-- Delete text (by replacing with empty string)
-
-**Important:** The `old_string` must match exactly, including whitespace. If it appears multiple times, the tool will error.
-
-### memory_rethink
-
-Completely rewrite a memory block's contents.
-
-**Parameters:**
-- `label`: Which memory block to rewrite
-- `new_memory`: Complete new contents
-
-**When to use:**
-- Condensing cluttered information
-- Major reorganization
-- Combining multiple pieces of information
-
-**When not to use:**
-- Adding one line (use `memory_insert`)
-- Changing specific text (use `memory_replace`)
-
-### memory_finish_edits
-
-Signals that memory editing is complete.
-
-**Parameters:** None
-
-Some agent architectures use this to mark the end of a memory update cycle.
-
-## Recall Memory
-
-### conversation_search
-
-Search prior conversation history using both text matching and semantic similarity.
-
-**Parameters:**
-- `query`: What to search for
-- `roles`: Optional filter by message role (user, assistant, tool)
-- `limit`: Maximum number of results
-- `start_date`, `end_date`: ISO 8601 date/datetime filters (inclusive)
-
-**Returns:**
-Matching messages with role and content, ordered by relevance.
-
-**Example queries:**
-- "What did the user say about deployment?"
-- "Find previous responses about error handling"
-- "Search tool outputs from last week"
-
-## Archival Memory
-
-Archival memory stores information long-term outside the context window. See the [Archival Memory documentation](/guides/agents/archival-memory) for details.
-
-### archival_memory_insert
-
-Add content to archival memory for long-term storage.
-
-**Parameters:**
-- `content`: Text to store
-- `tags`: Optional tags for organization
-
-**Common uses:**
-- Storing reference information for later
-- Saving important context that doesn't fit in memory blocks
-- Building a knowledge base over time
-
-### archival_memory_search
-
-Search archival memory using semantic (embedding-based) search.
-
-**Parameters:**
-- `query`: What to search for semantically
-- `tags`: Optional tag filters
-- `tag_match_mode`: "any" or "all" for tag matching
-- `top_k`: Maximum results
-- `start_datetime`, `end_datetime`: ISO 8601 filters (inclusive)
-
-**Returns:**
-Matching passages with timestamps and content, ordered by semantic similarity.
-
-## Deprecated Tools
-
-These tools are still available but deprecated:
-
-| Tool | Use Instead |
-|------|-------------|
-| `send_message` | Agent responses (no tool needed). See [legacy architectures](/guides/legacy/memgpt_agents_legacy) |
-| `core_memory_append` | `memory_insert` with `insert_line=-1` |
-| `core_memory_replace` | `memory_replace` |
