get_generation_details

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

No annotations are provided, so the description carries full burden. The description states 'Get details', which implies a read-only operation with no side effects. However, it does not disclose other behavioral traits such as authentication requirements, rate limits, or whether the generation must belong to the current user. The presence of an output schema partially mitigates this, but the description alone provides minimal transparency.

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 front-loads the essential purpose. It contains no wasted words but could benefit from structured sections or additional context (e.g., mentioning the source of the ID). However, for a simple tool, this level of conciseness is effective.

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 low complexity, a single required parameter, and the presence of an output schema, the description is minimally complete. However, it does not explicitly tie this tool to the broader workflow (e.g., using list_history first) or explain what 'details' entails. The param description partially fills this gap, but the main description could be more informative.

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 100%, so the baseline is 3. The tool description adds no extra meaning beyond what the input schema already provides: the schema already describes generation_id as 'The generation ID (from list_history)'. The description only restates 'by ID', which is redundant.

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 'Get details of a specific generation by ID' clearly identifies the action (getting details), the resource (a specific generation), and the method (by ID). It distinguishes this tool from siblings like list_history (which lists generations) and generate_image (which creates), making it unambiguous.

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 does not explicitly state when to use this tool versus alternatives. However, the parameter description for generation_id mentions 'from list_history', implicitly suggesting a workflow where list_history is used first. No explicit exclusions or context for when not to use this tool are provided.

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