get_items_by_id_ffprobe_by_fileid

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds no behavioral context beyond the HTTP route—no mention of auth needs, response characteristics, or side effects—so it contributes little beyond the annotations. There is no contradiction with annotations.

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 and mechanically structured as endpoint followed by args, with no wasted words. However, it is under-specified: the opening line is not an explanatory sentence, and the arg list adds no semantic value.

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 an output schema exists and annotations cover safety, the description doesn't need to explain return values. But it still fails to explain what ffprobe is, what id/fileid mean, or how this endpoint relates to similar item-file endpoints, so an agent cannot confidently select or invoke it correctly without external knowledge.

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 carries the full burden of explaining id and fileid, but it merely labels both as 'Path parameter.' This repeats the endpoint structure and adds no meaning about what those identifiers refer to, where they come from, or how they relate to each other.

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 names a specific verb and resource ('Get items ffprobe') and gives the REST path, so an agent can see it concerns ffprobe data for an item/file. However, 'ffprobe' is never explained and the synopsis is telegraphic, so the tool's actual purpose is less clear than a human-readable statement like 'Retrieve ffprobe metadata for a media file.' It is only weakly distinguished from siblings like get_items_by_id_file_by_fileid.

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 about when to use this tool versus alternatives, no exclusions, and no prerequisites. It only restates the endpoint and path parameters, leaving the agent to infer when ffprobe data is needed or how it differs from other item/file endpoints.

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