Get meme template details

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

With no annotations provided, the description carries full burden. It discloses that the tool returns dimensions, image URL, and suggested caption count. It does not mention side effects, errors, or rate limits, but for a read-only operation the description is adequate and adds value beyond the input schema.

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, well-structured sentence that front-loads the action and result. Every word adds value; no filler or repetition.

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?

Given the tool's simplicity (one param, no output schema, no annotations), the description covers purpose, input source, and output contents. It lacks mention of output format (e.g., JSON), but for a straightforward fetch, the description is largely complete.

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% with the slug parameter described. The tool description adds context on how to obtain the slug (from search or URL), which is helpful beyond the schema's example. Baseline of 3 is exceeded with this extra guidance.

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 clearly states 'Fetch one meme template by its slug' with the specific verb 'Fetch' and resource 'meme template'. It differentiates from siblings: search_meme_templates returns multiple, create_meme creates. The return contents (dimensions, image URL, caption count) are explicitly listed.

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 specifies the source of the slug ('from search_meme_templates or a memebo.at/templates/<slug> URL'), providing clear context on how to obtain the input. It does not explicitly state when not to use, but the simple fetch operation makes alternative guidance less critical.

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