hex_to_dec

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

No annotations are provided, so the description carries the disclosure burden. It states the core conversion but does not mention return format, handling of invalid input, or edge cases. The schema does add the 0x-prefix behavior, which helps, but more detail on output could improve 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 a single concise sentence that conveys the essential purpose without any filler. It is well-structured and front-loaded.

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?

For a simple one-parameter conversion tool, the description and schema are mostly sufficient. The absence of an output schema is not a major issue since the return value is inferable, but explicitly stating the output type (e.g., decimal number string) would make it fully complete.

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 provides a full description of the single parameter 'hex', including format details (with or without 0x prefix). The tool description adds no extra parameter meaning beyond the schema, so a baseline score of 3 is appropriate given the high schema coverage.

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 a hex string to decimal. It uses a specific verb and resource, and the name aligns with the function. It is easily distinguishable from sibling tools like dec_to_hex and hex_to_ascii.

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 usage context is clear from the description and tool name; there are no explicit 'when to use' or alternatives, but the purpose is unambiguous relative to the sibling conversions. The description implies when to use it (when a decimal representation is needed from hex) without needing exclusions.

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