memegen_templates

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

Annotations already declare readOnly, idempotent, openWorld, and non-destructive, so safety is covered structurally. The description adds only the data source and says nothing about result size, pagination, or whether template IDs returned feed into memegen_create.

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?

One short, front-loaded sentence with no waste. It is arguably undersized for the coordination role it plays with memegen_create, but it is well structured.

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-param list tool with annotations covering safety this is close to adequate, but there's no output schema and the description doesn't say what the templates look like or how they connect to memegen_create, leaving the agent to guess.

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?

Zero parameters, so the baseline is 4. There's nothing parameter-related to explain, and the description correctly implies a simple no-arg list call.

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?

Clear verb+resource: lists meme templates from memegen.link. Tells an agent exactly what it gets. However, it doesn't distinguish the purpose from the sibling memegen_create, so the boundary between listing and creating is left implicit.

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 guidance on when to use this versus memegen_create, no prerequisites stated. The typical use (discover template IDs before creating a meme) is inferable but never said.

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