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

No annotations are provided, so the description carries the behavioral burden. It does disclose the data scope (all options versus all criteria) and the source ('published price comparison'), which is useful. However, it does not describe return formatting, ordering, pagination, or the effect of the optional option parameter beyond what the schema already states.

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 compact phrase with no filler, and the most relevant information is front-loaded. It is grammatically a noun phrase rather than a full sentence, but every phrase earns its place.

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?

Complexity is low: one optional parameter, fully documented in the schema, and no output schema. The description explains what the table contains and its source. It could say more about the omitted-option behavior, but the schema already covers that with 'else all.'

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 coverage is 100%: the only parameter 'option' already has a clear description ('one option's name, else all'). The tool description only loosely echoes the term 'option' and adds no additional format, default, or edge-case semantics.

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 identifies the returned artifact: each option's value on every criterion of the US field service and trades software, presented as 'the full table.' It differentiates from siblings like compare_criteria and compare_options by emphasizing the complete table, but it lacks an explicit verb such as 'retrieves' or 'returns.'

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?

There is no explicit when-to-use or when-not-to-use guidance. The phrase 'the full table' implies this tool is for a comprehensive overview rather than the narrower compare_criteria or compare_options tools, but that implication is not made explicit.

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