Batch Update Presentation

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

The annotations already declare destructiveHint=true and readOnlyHint=false, so the mutation risk is known. However, the description adds no behavioral detail beyond that: it does not mention atomicity, partial failure, irreversible changes, or what kinds of modifications can be applied.

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. It is efficient and clear, though slightly under-specified for the complexity of the operation.

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?

This is a destructive, open-ended batch operation with an unstructured requests array, but the description is only one generic sentence. It leaves out valid request categories, failure semantics, and usage context. The presence of an output schema covers return values, not operational guidance.

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 schema already provides 100% parameter coverage, so the bar for the description is lower. The description adds no parameter-level context beyond the schema, and the open-ended 'requests' array in particular would benefit from an example or explanation of the expected shape.

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 ('apply batch updates') and the resource ('Google Slides presentation'), which is enough to differentiate it from read/create tools like get_presentation and create_presentation, and from the Docs/Forms batch update siblings by resource. It does not enumerate update types or scope, so it falls just short of a 5.

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 use this tool versus alternatives such as create_presentation, get_presentation, or batch_update_doc. An agent must infer from the name and sibling list that this is the choice for batch-mutating an existing Slides presentation.

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