Create Presentation

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=false, so the description does not need to cover those basics. It adds only 'new' to indicate a fresh resource is created, but provides no details on return values, side effects, or relationship to Google Drive. However, since an output schema exists and there is no contradiction with annotations, a mid-range score is appropriate.

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 sentence that conveys the essential action without filler. Every word earns its place, and the key verb and resource are front-loaded.

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 simple two-parameter create tool with full schema coverage, an output schema, and meaningful annotations, the one-sentence description is largely sufficient. It lacks only occasional context such as that the resulting presentation will be stored in Google Drive, but this is not critical given the schema and annotations.

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%: both user_google_email and title have adequate schema descriptions. The tool description adds no additional parameter meaning beyond what the schema already provides, so the baseline of 3 is correct.

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 ('Create') and resource ('a new Google Slides presentation'), making the core purpose clear. It does not explicitly differentiate from the sibling import_to_google_slides, which also results in a Slides presentation, so it falls short of full sibling 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 gives no guidance on when to use this tool versus alternatives such as import_to_google_slides or create_drive_file. There is no mention of prerequisites, when a new blank presentation is appropriate, or when another sibling would be a better choice.

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