get_media_users_by_user_by_file_name

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

The description discloses that the route is proxied and should not hit the API in production, which is valuable behavioral context. However, it lacks details on response format, error handling, or what happens if the file does not exist.

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 short with two sentences, but one is inaccurate. It is front-loaded but the inaccuracy detracts from its usefulness.

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 fails to explain what type of media is returned, the relationship between user_id and file_name, expected response format, and why the route is proxied. While the tool is simple, these gaps leave it incomplete.

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?

With 0% schema coverage, the description must explain parameters but instead misstates the input as a 'recipe slug'. It does not explain the meaning of user_id or file_name, leaving the agent confused about what values to provide.

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 states 'Takes in a recipe slug, returns the static image' but the tool name and input schema indicate it requires user_id and file_name, not a recipe slug. This mismatch makes the purpose unclear and potentially misleading.

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 guidance on when to use this tool versus sibling tools like get_media_recipes_by_recipe_assets_by_file_name. No context on prerequisites or alternatives is given.

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