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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds value by stating that all templates are returned and that default flag and layout settings are included, but it does not mention ordering, pagination, or any other runtime behavior. This is adequate for a zero-parameter list 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 brief and front-loaded with the action and resource. The first sentence repeats the tool title, which is slightly redundant, but the second sentence adds meaningful detail about the returned data. Overall, there is no wasted content.

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 zero-parameter, read-only listing tool with an output schema and comprehensive annotations, the description is fully adequate. It tells the agent exactly what will be returned and nothing else is needed to invoke it correctly.

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?

There are no parameters, and schema description coverage is 100% per the context signals. The description correctly focuses on the output scope rather than parameter details, since none exist. Baseline 4 is appropriate.

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 ('List'/'Return') and a specific resource ('saved share template'), and clarifies the scope as 'every' template including default flag and layout settings. This clearly separates it from sibling tools that operate on other resources or perform deletion.

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 makes the use case clear: retrieve all saved share templates, including their default flag and layout settings. There are no exclusion conditions or alternatives to compare against; it is a simple read-only listing tool, so the lack of explicit 'when not to use' guidance is acceptable.

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