createSectionDividerSlide

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

No annotations are provided, so the description bears the full burden. It mentions 'create or update' and the required slide elements, but does not elaborate on the update behavior (e.g., that it only updates if _index is provided) or any side effects. Since the input schema covers _index behavior, transparency is adequate but not enriched.

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 two sentences: the first states purpose and requirements, the second gives usage context. No unnecessary words; efficient and clear.

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 tool with 3 parameters and no output schema, the description provides the essential purpose and usage context. It could mention the result of the operation, but this is not critical given the schema and typical slide creation pattern.

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%, so the schema already documents the parameters. The description adds the requirement that the slide must include both a heading and subheading, but this is consistent with the required fields. No additional semantic detail beyond the schema.

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 tool creates or updates a section divider slide with a large heading and subtitle. It explicitly distinguishes this from other slide types by specifying the slide's role as a section separator.

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 a clear usage context: 'Use this when the user wants to create a single slide that clearly introduces or separates a new section.' While it doesn't explicitly state when not to use, the context differentiates it from the many sibling tools dedicated to other slide types.

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