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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds useful framing about what the response contains (template name plus numeric id), but says nothing about ordering, completeness, or whether the list is workspace-scoped.

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?

A single short sentence with no waste, front-loading the catalog name before the field list. It is a noun phrase rather than a complete statement, which costs a little clarity but nothing in length.

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 no-parameter read tool with annotations covering safety, the description is close to sufficient, and the output field hint helps in the absence of an output schema. It still leaves the relationship to workspace templates unexplained, which is the main ambiguity an agent would face.

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 takes zero parameters, so the baseline is 4 and there is nothing the description could clarify. The mention of the two returned fields is a small bonus rather than a requirement.

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 identifies the resource as a 'product template catalog' and names the returned fields (name, numeric id), so the agent can infer it is a listing tool. However, there is no verb and no differentiation from the sibling tools list_workspace_templates and get_workspace_template, leaving the exact scope of 'product' templates ambiguous.

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?

No when-to-use guidance is given, and no alternative is mentioned despite a near-identical sibling (list_workspace_templates) in the catalog. The agent has to guess which catalog it needs.

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