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

The description is richer than the bare annotations (which only contain a title): it explains the PowerPoint 2016+ modern-comment constraint and says the response is a JSON confirmation. However, it does not disclose whether changes are persisted automatically, what happens with invalid slide_index values, or any other side effects beyond the obvious mutation.

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 summary line is front-loaded and every following line in the Args/Returns block carries necessary information for a seven-parameter tool. There is no filler or repetition.

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?

Despite having no output schema and minimal annotations, the description is nearly complete: it covers all parameter semantics, the return type, and an environment constraint. The main gap is the inconsistency with the schema's optional/required claims and the lack of persistence/error behavior.

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 fully compensates by explaining every parameter, including 1-based slide indexing, point units for left/top, and environment-variable defaults for author fields. It is slightly flawed because it labels slide_index and text as required while the input schema declares no required properties and gives both defaults.

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 opens with a specific verb and resource: 'Add a comment to a slide (PowerPoint 2016+ modern comments).' This clearly states what the tool does and is enough to tell it apart from the get_comments/delete_comment siblings, though it does not explicitly name an alternative.

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 given about when to choose this tool over alternatives or when not to use it. The usage context is only implied by the name and first sentence, and there is no mention of prerequisites such as an open presentation.

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