Agent Tool Design FAQs

Question 1

How do tool descriptions affect agent behavior?

Accepted Answer

Tool descriptions function as prompt engineering. Effective descriptions explain exactly what the tool does, when it should be triggered, what inputs it requires, and what the output structure looks like.

Question 2

Why is architectural reduction important for agents?

Accepted Answer

Architectural reduction replaces specialized, restrictive tools with general-purpose primitives (like file system access). This allows powerful models to use their internal reasoning to solve problems rather than being constrained by predefined workflows.

Question 3

What is the consolidation principle in tool design?

Accepted Answer

The consolidation principle is the practice of combining narrow, overlapping tools into single comprehensive tools. This reduces agent ambiguity and token consumption by providing a clearer contract for the model.

Question 4

Can I use AI to optimize my tool definitions?

Accepted Answer

Yes. This skill recommends a 'Tool-Testing Agent Pattern' where an agent analyzes its own failure modes and suggests description improvements to help future agents avoid the same mistakes.

Question 5

How should I name MCP tools correctly?

Accepted Answer

Always use fully qualified names in the format 'ServerName:tool_name'. This prevents 'tool not found' errors when multiple MCP servers are active simultaneously.
