slides_get_thumbnail

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

The description implies a read operation by stating it generates a URL, but does not disclose authentication requirements, rate limits, error handling, or consequences of missing slides. Since annotations are absent, the description carries the full burden for behavioral clarity; it is adequate but not detailed.

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 a single sentence that is front-loaded with the key action ('Generate') and resource. No extraneous words.

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?

The description explains the primary behavior and return value (URL) but does not cover error conditions, URL expiration, or dependencies. Given the simplicity of the tool, it is mostly 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 coverage is 100%, so baseline is 3. The description does not add significant meaning beyond the schema; it implicitly refers to presentationId and pageObjectId but lacks details about thumbnailSize behavior or constraints.

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 it generates a thumbnail image URL for a specific slide, using the verb 'generate' and specifying the resource (slide). It distinguishes itself from sibling slides tools like slides_get_page by focusing on thumbnail URL generation.

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 is provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions for using this tool.

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