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

Annotations already declare this a safe, idempotent, closed-world read (readOnlyHint, idempotentHint, destructiveHint=false), so safety is covered. The description adds content-level context (German/English URLs, a designer deep link that preselects templates), which is useful, but says nothing about return format, pagination, or ordering.

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?

It is a single front-loaded sentence that leads with the resource and then packs the template examples and returned artifacts efficiently. The parenthetical enumeration makes it dense but every element 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?

With no output schema, the description does part of the work by describing what is returned (URLs in two languages and the deep link). For a 0-param listing tool whose annotations already cover the safety profile, this is close to complete, though the exact response shape remains unspecified.

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; there is no parameter semantics to clarify, and the description correctly does not invent any.

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 names the resource (occasion landing pages) and enumerates the concrete templates it exposes (photo mug, birthday, couples, pet, Mother's Day, Christmas), so an agent knows exactly what this tool returns. It does not, however, explicitly differentiate itself from related siblings like get_design_options or create_design_link despite the shared 'designer deep link' concept.

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?

Usage is only implied: the catalog description suggests the tool is for browsing occasion-based template pages, but there is no statement of when to prefer it over create_design_link or get_design_options. No exclusions or prerequisites are given.

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