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

The description adds no behavioral details beyond what the annotations already establish. It does not disclose side effects, persistence behavior, duplicate-title handling, auth requirements, or return value. The annotations indicate a non-read-only, non-destructive operation, and 'Create a photo album' is consistent with that, but no additional transparency is provided.

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, front-loaded sentence with no filler words. It is concise and easy to parse, though the brevity contributes to the under-specification seen in other dimensions. As a concise statement of purpose it works well, but it lacks any supporting structure such as alternative-routing or parameter notes.

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?

For a tool with two parameters, no output schema, and no parameter descriptions, the one-line description is not sufficient. The sibling list includes closely related operations like upload_photo and add_to_album, but the description does not explain how album creation relates to them. An agent would not know what the tool returns or what to do after creating an album, making the context 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?

Schema description coverage is 0% and the description does not mention either parameter. 'title' is required and 'frameId' is optional per the schema, but the description gives no meaning, format, or constraint elaboration for either. With no schema descriptions and no compensatory explanation, parameter semantics are essentially missing.

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 a specific verb and object: 'Create a photo album.' It clearly identifies the action and resource, and the verb 'create' distinguishes it from related sibling operations like update_album, delete_album, add_to_album, and remove_from_album. There is no ambiguity about what this tool does.

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?

No guidance is provided on when to use this tool versus alternatives such as upload_photo, add_to_album, or set_device_album. The description gives no context about prerequisites, such as whether a frameId is needed or whether an album must exist before adding photos. An agent is left to infer the appropriate usage entirely from the tool name and sibling list.

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