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

No annotations are provided, so the description carries the full behavioral burden. It only describes content ('criteria and any filters') and does not disclose whether the operation is read-only, what the output format is, or any side effects. It is not misleading, but it is very thin.

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, but the grammar is awkward ('of the Where nearshoring wins, and where it does not comparison') and the comparison name is not clearly delimited. It is concise in length, but the structure hurts clarity.

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?

With no parameters and no output schema, a short description can be sufficient, and the sentence does identify the content domain. However, it does not explicitly state that the tool returns or describes the criteria, leaving basic call semantics to inference. This is nearly adequate for a zero-input info tool but not 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 tool has zero parameters and an empty input schema, so there is no parameter meaning for the description to clarify. The baseline of 4 for a zero-parameter tool applies.

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 tool as exposing the criteria and filters for a specific comparison ('Where nearshoring wins, and where it does not'), which is a meaningful resource and somewhat distinguishes it from compare_options and compare_table. However, it lacks an action verb and is phrased as a fragment rather than a clear operation, so an agent must infer the intended action.

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?

No guidance is given about when to use compare_criteria versus compare_options or compare_table. The description only names the content; it does not state conditions, exclusions, prerequisites, or alternatives.

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