## Overview

Reserved for research on tool augmentation, function calling, and MCP-related tool ecosystems. In nexus-agents, tool-use is foundational to the entire MCP server (30+ registered tools) and not typically tracked as research techniques — the techniques register higher-level behaviors.

## Indexed Papers

A small number of papers under `topic: tool-use` in [registry/papers.yaml](../../registry/papers.yaml). Tool-related security papers (e.g., ClawGuard arxiv-2604.11790) are filed under [security/](../security/README.md).

## Techniques

None standalone. Tool-use is implicit in the MCP server architecture (see CLAUDE.md MCP Tools Reference).
