generate_xml_schema

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

With no annotations, the description carries the full burden. It discloses that the tool is a simple retrieval ('Returns the raw XSD'), implies a read-only behavior, and adds useful context about the schema's role. It does not discuss potential response formatting or side effects, but for a zero-parameter accessor this is adequate.

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 two sentences with no redundancy. It front-loads the core behavior in the first sentence and adds practical use-case context in the second, making every word earns 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?

Given the tool's simplicity (no parameters, no output schema), the description is complete. It explains what is returned, why the XSD is useful, and how it relates to generate_xml and create_document_from_xml, so an agent can correctly select and invoke it.

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 schema coverage is trivially 100%, so the baseline is 4. The description adds no param details because none are needed; it is clear that no input is required.

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 a specific verb ('Returns') and names the exact resource (the raw XSD, Xml.xsd). It clearly distinguishes the tool from siblings by explaining that the schema is shared by generate_xml's output and create_document_from_xml's input, and by positioning it as a schema-authoring aid rather than a generation tool.

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?

It explicitly states when to use this tool: when authoring XML by hand or via transform and wanting schema validation/autocomplete. It also gives an alternative ('rather than reverse-engineering the shape from a generate_xml example'), which helps an agent decide between this and another approach.

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