get_recipe_timeline_event_img

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

No annotations are provided, so the description must disclose behavior. It says it returns a static image and notes that the route is proxied in Docker, implying it may not work in production. However, it lacks details on side effects, authentication requirements, error behavior, or whether the image is returned as binary data or a URL. Some transparency but incomplete.

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 concise with two sentences, front-loading the purpose and including the HTTP route for clarity. The proxying note is important but could be clearer. Overall efficient, though the route could be omitted as it's not essential for an agent.

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 exists, yet the description only says 'returns the static image' without specifying if it's binary data, a URL, or the format. Given three parameters and no output details, the description is insufficient for an agent to fully understand what is returned. The proxying note adds operational context but does not complete the picture.

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 0%, so the description should compensate. It repeats that it takes a recipe ID and event timeline ID, but does not explain the 'file_name' parameter or the enum values (original.webp, etc.). The schema provides types and enums, but the description adds no additional meaning beyond the obvious. Insufficient for 0% coverage.

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 gets a static image for a recipe timeline event, specifying the endpoint and required IDs. However, it does not differentiate from the similar sibling tool 'get_recipe_img', which also retrieves a recipe image. The purpose is clear but lacks distinction.

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 alternatives like 'get_recipe_img'. It mentions that the route is proxied and should not hit the API in production, which is more of a deployment note than usage context. No explicit when/when-not or alternative comparisons.

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