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

With no annotations available, the description carries the full burden of behavioral disclosure, but it reveals nothing. It does not state whether the tool returns a score, a boolean, a strength label, or what criteria are used.

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 extremely short but this is under-specification, not conciseness. 'Password Strength: Password Strength' contains no informative content and does not earn 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?

For a tool with no annotations, no output schema, and only a tautological description, an agent has no way to know what the tool returns, how the password is evaluated, or how this differs from sibling password tools. The description is completely inadequate.

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% because the 'password' parameter has a description ('Password to process'). The tool description adds no parameter-level meaning, so the baseline of 3 applies, even though 'process' is vague.

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 'Password Strength: Password Strength' is a pure tautology—it restates the tool name without any verb, resource, or behavior. It does not distinguish this tool from siblings like x402-password-entropy, x402-password-leak, or x402-is-strong-password.

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 provided about when to use this tool versus the many related password tools in the sibling list. The description gives no context, scenarios, or exclusions.

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