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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does disclose a significant cost: '$0.05 USDC on Base mainnet.' However, it does not specify whether the operation is read-only, what side effects might occur, or what the return format is. The cost is a valuable addition, but other behavioral aspects remain undisclosed.

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, front-loaded sentence that conveys purpose and cost with zero wasted words. Every phrase earns its place, making it efficient and easy to parse.

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?

The tool has a simple input (one array) and a clear stated purpose, but with no output schema or annotations, the description does not explain what the tool returns or how the results are presented. The cost disclosure is helpful, but the missing return-value description leaves some ambiguity for an agent trying to use the tool correctly.

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 input schema defines 'cases' as an array with required fields id, expected_skills, and observed_skills. The description adds context by calling them 'skill activations' and referring to 'test cases,' which aligns with the schema fields. However, it does not add further details about parameter format or constraints beyond what the schema already provides. With 0% schema description coverage, the description partially compensates but remains at baseline.

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 uses the specific verb 'Compare' and clearly identifies the resource as 'expected and observed skill activations across test cases.' It also states the intended outcome: to 'expose missed and spurious routing.' This clearly distinguishes it from the sibling tools, which are all preflight/checker tools in different domains.

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 provides clear context that this tool is for comparing expected and observed skill activations in test cases to identify routing issues. It does not explicitly state when not to use it or name alternatives, but the context is strong enough for an agent to infer appropriate use cases.

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