roman_to_arabic

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

No annotations are provided, so the description carries full behavioral disclosure burden. It states the conversion action but does not describe error handling (e.g., invalid Roman numerals), output format, or any constraints like input validation rules. This leaves significant behavioral gaps for a tool with no structured safety hints.

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 a single, efficient sentence with zero redundant information. It front-loads the core purpose and includes helpful domain/category tags without unnecessary elaboration, making it optimally concise.

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 no annotations, no output schema, and a single parameter with 0% schema coverage, the description provides basic purpose and domain context but lacks details on behavior, error handling, and output format. It is minimally adequate for a simple conversion tool but misses completeness for reliable agent invocation.

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?

Schema description coverage is 0%, but the description adds meaningful context by specifying that the input is a 'Roman numeral' (string type). However, it does not detail format expectations, valid characters, or case sensitivity, leaving the single parameter partially documented but incomplete.

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 specific action ('Convert'), resource ('Roman numeral'), and target representation ('Arabic number'), with explicit domain/category context. It precisely distinguishes from its sibling 'arabic_to_roman' by specifying the opposite conversion direction.

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 implies usage context through the domain/category tags ('arithmetic, general'), but does not explicitly state when to use this tool versus alternatives like 'arabic_to_roman' or other conversion tools. It provides clear functional intent but lacks explicit comparative guidance.

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