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

No annotations are provided, so the description must carry the behavioral burden. It clearly describes the table's content and scope, which is useful. It does not disclose output format, how the optional option parameter affects results, or whether any filtering or defaulting occurs beyond what the schema indicates.

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 sentence with no filler and the core idea is front-loaded. However, the phrase 'Where nearshoring wins, and where it does not comparison' is syntactically tangled and reduces immediate readability.

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 tool with one optional parameter and no output schema, the description conveys the primary return content well. It still leaves some gaps such as what happens when option is omitted versus explicitly given, and what the table structure looks like, but the schema covers the parameter part adequately.

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 100%, with the option parameter documented as 'one option's name, else all'. The description reinforces that each option has a value on every criterion but adds no new semantic detail 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 states the tool's output: a full table showing each option's value on every criterion. This separates it from siblings like compare_criteria and compare_options, which likely show focused subsets. The wording is awkward and lacks an explicit verb like 'returns', but the intent is clear.

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 statement about when to use this tool versus compare_criteria or compare_options. The phrase 'full table' implies it is the exhaustive comparison view, but the agent must infer the exact routing decision from tool names and this single phrase.

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