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

No annotations are provided, so the description carries full burden. It states it's a read operation, implying it's non-destructive, but doesn't disclose any behavioral traits like authentication requirements, rate limits, pagination, error conditions, or what the output contains. The description is minimal and lacks necessary context for safe invocation.

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, clear sentence with no wasted words. It's front-loaded with the core purpose and efficiently communicates the essential action. Every word earns its place in this concise statement.

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 has an output schema (which should document return values), the description's minimalism is somewhat acceptable. However, with no annotations and 0% schema description coverage, the description should do more to explain parameter usage and behavioral context. It's borderline adequate but leaves significant gaps.

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 schema provides no parameter descriptions. The description mentions 'Google Presentation' which hints at 'presentation_id', but doesn't explain what 'user_google_email' is for or how parameters interact. It adds minimal meaning beyond the bare schema, failing to compensate for the coverage gap.

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 action ('Read') and resource ('all comments from a Google Presentation'), making the purpose immediately understandable. It doesn't explicitly differentiate from sibling tools like 'read_document_comments' or 'read_spreadsheet_comments', but the specificity about 'Google Presentation' provides some 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 provides no guidance on when to use this tool versus alternatives. There are sibling tools for reading comments on documents and spreadsheets, but no indication of which to choose for different file types or scenarios. No prerequisites or exclusions are mentioned.

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