themes_get_slide_thumbnail

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

No annotations exist, and the description only repeats the tool's purpose without disclosing behavioral traits like whether it is read-only, requires authentication, or returns data (e.g., image URL vs. binary).

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 concise sentence that is front-loaded with the key information. While very brief, it avoids unnecessary words and is easy to parse.

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?

No output schema is provided, and the description does not explain what the thumbnail data looks like (e.g., a URL, base64, or file). This leaves ambiguity for the agent about what to expect in the response.

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% with both parameters described. The description adds no further meaning beyond what the schema already provides, justifying the baseline score of 3.

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 the action (Get) and resource (thumbnail for a specific theme slide), making it distinct from siblings like themes_get_slide (which returns the slide) and themes_get_all (which returns all themes).

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 tool versus alternatives. Sibling tools exist for different thumbnail types (e.g., masks_get_thumbnail, playlists_get_thumbnail), but no differentiators are provided.

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