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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It reveals that the route is proxied and should not be used in production, which is useful. However, it does not mention authentication requirements, rate limits, or whether the tool is read-only. The description adds some value beyond the schema but is not comprehensive.

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 consists of two short sentences, each providing essential information. The first sentence explains the core functionality, and the second adds important contextual behavior about the proxied usage. There is no redundancy or unnecessary text, making it highly concise and 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?

Given the lack of output schema and annotations, the description provides moderate context: it explains the inputs and the return value (static image) and includes a behavioral note about proxying. However, it fails to document the file_name parameter and does not specify the response format (e.g., binary, URL). These gaps reduce completeness for a tool that requires three parameters and serves files.

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 description mentions two of the three required parameters (recipe id and timeline event id) but omits the file_name parameter entirely. Since schema description coverage is 0%, the description should compensate by explaining all parameters. The file_name parameter has an enum of image sizes, but this information is missing, reducing the tool's usability.

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 that the tool takes a recipe id and event timeline id and returns a static image, indicating a specific verb and resource. However, it does not specify whether the image is returned as binary data or a URL, leaving some ambiguity. The tool name and sibling tools help differentiate it from other media tools, but the description alone could be more precise.

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 provides no explicit guidance on when to use this tool versus alternatives like get_media_recipes_by_recipe_images_by_file_name. It mentions the route is proxied and should not hit the API in production, which hints at a development/testing context, but this is not a clear usage guideline and does not help an agent decide when to invoke this tool over others.

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