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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is well covered. The description adds behavioral context by specifying the content (links to sitemap, docs, contact, discovery documents), which is useful beyond annotations. No contradiction with annotations.

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 that front-loads the primary purpose ('What Wild Orange Charters is') and then lists the link types. It is concise and free of fluff, though the phrasing is slightly informal. It earns its place with no unnecessary words.

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 parameters and no output schema, and with annotations covering safety, the description is sufficiently complete. It specifies what the tool returns (links to various documents), which is the key information an agent needs. The term 'discovery document' could be more precise, but overall it is adequate.

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, so schema coverage is trivially 100%. The description adds no parameter details because none exist. With no parameters, the baseline score of 4 is appropriate; the description does not need to explain anything.

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 clearly states that the tool provides information about Wild Orange Charters and lists the types of links it returns (sitemap, docs, contact, discovery documents). It is a specific resource description and not a tautology. However, it does not explicitly contrast with siblings read_page and search_pages, so it lacks strong differentiation.

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 implies usage for obtaining site overview and links, but it does not state when to use this tool versus alternatives like read_page or search_pages. There is no explicit when/when-not guidance, though the purpose is fairly self-evident.

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