Hardened Google Workspace MCP

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions that the tool creates a new presentation but doesn't specify whether this requires write permissions, how errors are handled, or any rate limits. The return format is briefly described, but behavioral traits like side effects or authentication needs are omitted.

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 well-structured with clear sections for Args and Returns, making it easy to parse. It's concise with no redundant information, though the front-loading could be improved by integrating the return details more seamlessly.

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 tool's moderate complexity (2 parameters, no annotations, but with an output schema), the description is adequate but incomplete. It covers the basic purpose and parameters but lacks usage context, error handling, and authentication details, which are important for a creation tool in a Google ecosystem.

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?

The description adds meaningful context for both parameters: it explains that user_google_email is required and specifies the default value for title. Since schema description coverage is 0%, this compensates well by clarifying parameter roles, though it doesn't detail format constraints like email validation.

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 the verb 'Create' and resource 'Google Slides presentation', making the purpose specific and understandable. It distinguishes from siblings like 'create_doc' or 'create_sheet' by specifying the presentation type, though it doesn't explicitly contrast with them.

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 like 'create_doc' or 'create_spreadsheet'. The description lacks context about prerequisites, such as whether the user needs specific permissions or authentication, which is critical given the user_google_email parameter.

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