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

Since no annotations are provided, the description carries the behavioral disclosure burden. It clearly indicates the tool only returns tool names and descriptions, is non-mutating, and requires no prerequisite. More detail on output format would improve it, but the description is adequate for a simple discovery 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 concise sentences with the purpose front-loaded and the non-prerequisite caveat included. Every sentence 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?

For a one-parameter discovery tool, the description and rich schema provide enough context to select and invoke it correctly. The only minor gap is a more detailed output shape, but the description already states that tool names and descriptions are returned.

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%, and each enum value has a clear, meaningful explanation. The description itself adds no extra parameter semantics beyond saying the tool is domain-based, so the baseline of 3 applies.

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 ('Discover') and identifies the resource ('available Sherweb tools by domain'). It also states what it returns ('tool names and descriptions') and distinguishes itself from operational siblings by positioning itself as a discovery aid.

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 that this is a help/discovery aid and not a prerequisite, clarifying when not to call it. It does not name alternative sibling tools, but the domain enum in the schema provides clear domain context.

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