title_case

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

With no annotations, the description carries the burden of disclosing behavioral traits. It fails to explain what 'major words' means (e.g., handling of articles, prepositions, conjunctions), how punctuation is treated, or whether the tool preserves existing capitalization. This lack of specificity reduces transparency.

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?

The description is extremely concise: one clear sentence followed by a parameter list. Every word serves a purpose, and there is no redundant or extraneous information. It is well-structured and easy to scan.

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?

Given the tool's simplicity and the presence of an output schema (which clarifies return values), the description is reasonably complete but could benefit from clarifying the capitalization rule (e.g., 'using standard English title case, where articles and prepositions are lowercased unless they are the first or last word'). This would enhance completeness.

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 input schema has no descriptions (0% coverage), so the description must compensate. It repeats the parameter name ('text') and adds a basic explanation ('Text to convert to title case'), but does not specify valid formats, length limits, or encoding. This adds minimal but non-zero value beyond the schema.

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 clearly states the tool's function: converting text to title case, with a specific verb ('Convert') and resource ('text to title case'). It distinguishes itself from sibling tools like 'convert_case' and 'capitalize_text' by specifying the transformation type.

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 description provides no guidance on when to use this tool versus alternatives, such as when text requires more nuanced casing rules or when to use 'capitalize_text' instead. No prerequisites, exclusions, or context are mentioned.

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