uppercase

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the behavioral burden; 'Convert text to uppercase' fully states the transformation and implies a pure, side-effect-free operation. Nothing about the tool's behavior is hidden or surprising for this simple string function.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single four-word sentence states everything necessary with no filler. The operative verb and object are front-loaded, making the description immediately scannable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With only one required string parameter and an existing output schema, the description plus schema leaves no ambiguity about how to invoke the tool or what it returns. The low complexity means no additional prerequisites, failure modes, or side effects need to be explained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has one required 'text' string property with 0% description coverage. The description restates 'text' in context, showing it is the input to transform, but supplies no additional format, encoding, or edge-case semantics beyond what the schema's type and title already imply.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Convert') and names the resource and result ('text' to 'uppercase'), so the tool's function is unambiguous. It does not explicitly distinguish itself from siblings like lowercase, but the operation is clear on its own.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The sentence implies the tool is for any case where uppercase output is needed, and the schema confirms text is required. However, it provides no explicit when-not-to-use guidance or pointers to sibling tools, so usage context is only implied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
