Bug Description

When an agent's model settings are modified (e.g., context quantity adjustment), deleting and re-adding the agent causes the following critical functions to fail:

1. Knowledge Base Invocation Failure:

   • After re-adding the agent, the input box cannot properly invoke knowledge base functionality.
   • Users cannot access or use relevant knowledge base content in conversations.

2. MCP (Multi-Parameter Configuration) Invocation Failure:

   • After modifying model settings, MCP functionality does not respond properly.
   • Users cannot achieve expected functional interactions through MCP.

3. Slash Command (/command) Invocation Failure:

   • After re-adding the agent, slash commands (such as /command) cannot be correctly parsed or executed.
   • Users cannot trigger predefined functions or workflows through slash commands.

Steps To Reproduce

1. Prerequisites: Ensure that an agent A is already running normally in the system, and this agent has successfully linked to a knowledge base, MCP functionality, and supports slash command invocation.
2. Step 1: Modify agent model settings. Navigate to agent A's configuration page and modify its model settings, such as adjusting the "Context Length" parameter or selecting a different model version. Save these modifications.
3. Step 2: Delete the agent. Delete agent A from the home page list.
4. Step 3: Re-add agent A. Add agent A again, which should be the same as the original agent A (or at least its name/ID matches it).
5. Step 4: Attempt to invoke functions. Navigate to the conversation interface of the re-added agent A on the home page.
   • Try to use the knowledge base-related button in the input box and observe whether the knowledge base invocation button can be displayed.
   • Try to invoke MCP functionality (operate according to the specific usage method of MCP).
   • Enter the / character in the input box and observe whether the expected command list can pop up.

Expected Behavior

Expected Behavior:
After executing the reproduction steps, the re-added agent A should be able to properly invoke its associated knowledge base and MCP in the conversation interface, and when entering the / character, it should correctly display and use the slash command functionality. The deletion and re-addition operations of the agent should not cause the loss or failure of its core functional configurations.

Observed Behavior:
After executing the reproduction steps, when users operate in the conversation interface of the re-added agent A:

• The input box cannot recognize or invoke any associated knowledge base content.
• The input box cannot invoke or link to any MCP functionality.
• When entering the / character in the input box, MCP and knowledge base cannot be invoked.
