Tool Execution and Thinking Display
LVIS visually surfaces tool calls and what the LLM is thinking through. Every tool call branches into auto-run / confirmation card / dialog based on its risk level and category.
Thinking block
Shows what the LLM is "thinking" while composing an answer, in a light quote block. Click to collapse / expand.
Tool execution card
Tool name · a summary of the inputs used · the result, all in one card. Long results expand into a larger view via "See more."
Three sources of tools
- Built-in host tools — tools provided by LVIS itself. The most trusted.
- Plugin tools — tools registered by an installed plugin. Operate within their own domain.
- External MCP tools — tools from an external MCP server registered by the user. Conservatively classified as "medium risk" by default.
Every tool call is logged
Whether it succeeds or fails, every tool call leaves a one-line record in secure storage. External code execution is logged separately and retained longer.
