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

With no annotations, the description carries the full burden of behavioral disclosure, but it only says 'sort strings' and omits key behavior such as sorting order, mutability, input handling, edge cases, and return format. It provides no behavioral insight beyond the tool's own name.

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 the 'Sort Strings:' prefix is redundant with 'Sort strings.' and the text reads as under-specification rather than purposeful concision. No useful structure beyond a bare restatement of the name.

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?

This is a 0-parameter tool with no output schema, so the description must define how input is supplied and what the result looks like. It does neither: no ordering convention, return shape, example, or mention of the many sibling sort tools. An agent cannot reliably invoke or interpret this tool.

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 has zero parameters, so the description does not need to explain parameter meaning. Schema coverage is trivially 100%, and with 0 params there is no parameter semantics burden on the description.

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 'Sort Strings: Sort strings.' simply restates the tool name and adds no specification beyond what the name already implies. It does not describe what kind of strings are sorted, whether ordering is lexicographic/case-sensitive, or how it differs from sibling sort tools.

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 this tool instead of closely related siblings such as x402-sort-lines or x402-sort-numbers. There is no context, condition, or exclusion stated, leaving the agent to infer usage entirely from the name.

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