How to Interrupt specific tool calls in create_react_agent?

[Hakstar]

Hi all,

I’m building a multi-agent coordination system using LangGraph.
At the outer level, I have a coordinate-style graph, and each agent inside is created with create_react_agent, with multiple tools configured.

What I want to achieve

I’d like to implement an interrupt → user confirmation → resume flow:

Before calling one specific tool (e.g. a database query or external API call), the agent should pause execution.

The system would then hand over to the user, so they can review/modify the tool input parameters.

Once confirmed, the agent continues execution as normal.

What I’ve tried

I used interrupt_before, like this (simplified pseudo-code):

agent = create_react_agent(
    name="research_agent",
    model=llm,
    tools=[search_tool, db_tool, write_tool],
    interrupt_before=["tool"],
)

This works, but it interrupts all tool calls — meaning every time the agent tries to use any tool, execution stops.
That’s not what I want, because most tools (like search_tool or write_tool) don’t need user confirmation.

The problem

I want to scope the interruption only to certain tools (e.g. only db_tool), while the rest run without interruption.

Question:

• Is there a way to configure create_react_agent so that only selected tools trigger interruption?

• Or do I need to wrap the target tool in some custom handler/graph node to implement this behavior?

• Any patterns, best practices, or example code for this would be greatly appreciated!
