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

No annotations are provided, so the description carries the full burden. It discloses that the output is a signed download link, that coordinates are based on measured layouts to match the gallery, and that text longer than slots[].max_chars will be clipped. These are meaningful behavioral traits beyond what the schema implies. It does not cover error cases or authentication, but for a read-only export operation this is adequate.

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 four well-structured sentences that lead with purpose, then usage examples, then functional details and a caveat. Every sentence contributes information; the example phrases are succinct and useful. There is no redundancy or unnecessary jargon, making it efficient for an agent to parse.

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 two-parameter tool with no output schema, the description is complete. It explains the return value (signed link), the input structure (layout ids and slot text), the dependency on get_layout for ids/max_chars, and the clipping limitation. It also confirms that the output matches the gallery view. Nothing essential for an agent to call this correctly is missing.

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 provides 100% coverage, so the baseline is 3. The description adds value by explaining that slot ids and max_chars come from get_layout and by warning that long text gets clipped, which directly affects how the 'slides' parameter should be populated. This goes beyond the schema's field descriptions and helps the agent construct valid inputs.

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 states a clear verb ('Turn') and resource ('a deck into a downloadable .pptx file'), and even provides three concrete request examples in English and Korean to recognize when to invoke it. This is distinct from all sibling tools, which are about retrieving layouts, themes, or starter kits, so there is no ambiguity about what this tool does.

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 gives explicit example phrases that indicate when to use the tool, and it notes that slot ids and max_chars come from get_layout, which implies a prerequisite workflow. It does not explicitly contrast with sibling tools, but since it is the only export tool in the set, alternatives are not needed. The usage context is clear, though exclusion criteria are absent.

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