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

With no annotations provided, the description carries the burden of behavioral disclosure. It adds the key precondition that URLs must come from search_docs and implies read-only behavior ('Fetch'). While it doesn't cover error handling or output format, the mandatory prerequisite is a valuable behavioral disclosure for a simple read tool.

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 long, with the purpose front-loaded and the critical usage prerequisite in a clear second sentence. Every word contributes value; there is no redundancy.

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 (one parameter, no output schema), the description adequately covers purpose, prerequisite, and parameter compatibility. The absence of an output schema means the description need not explain return values, and the 'full content' phrasing gives a general expectation. Minor gap: no detail on response structure, but this is acceptable for a simple fetch 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 schema already documents the 'url' parameter with a format example, giving 100% coverage. The description adds extra meaning by noting that only URLs from search_docs are compatible, which clarifies that not arbitrary URLs will work. This enhances the schema-provided semantics.

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 ('Fetch') and clearly identifies the resource ('full content of a Hytale modding documentation page'). It distinguishes itself from the sibling tool search_docs by indicating it retrieves full content rather than performing a search.

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 explicit usage guidance: 'You MUST use the search_docs tool first to get a list of URLs that are compatible with this tool.' This clearly states when to use this tool and the required prerequisite, effectively distinguishing it from search_docs.

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