Agent Tool Design FAQs

Question 1

Why are error messages important for agent tools?

Accepted Answer

Unlike human developers, agents need actionable error messages that explicitly describe what went wrong and how to fix the parameters to enable automated recovery.

Question 2

How should I name tools when using the Model Context Protocol (MCP)?

Accepted Answer

Always use fully qualified names in the format 'ServerName:tool_name' to prevent 'tool not found' errors when multiple servers are active.

Question 3

What is architectural reduction in agent systems?

Accepted Answer

Architectural reduction is the strategy of replacing specialized tools with general-purpose primitives, like direct file system access, to leverage the model's inherent reasoning.

Question 4

How do I improve an agent's success rate with my tools?

Accepted Answer

Focus on tool description engineering: clearly state what the tool does, when it should be used, what inputs it accepts, and what the output format looks like.

Question 5

What is the Consolidation Principle in tool design?

Accepted Answer

It is the practice of preferring a single, comprehensive tool over multiple narrow tools to reduce agent ambiguity and context token consumption.
