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

Annotations already declare the safety profile (readOnly=false, destructive=false, idempotent=true), so the bar is lower. The description adds real value by describing the transformation output (slide-per-page, editable text boxes), but it omits the overwrite/pre-existence behavior implied by the schema, which is notable given idempotentHint=true.

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?

A single front-loaded sentence with zero filler that states the conversion and the two most important output characteristics immediately.

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?

An output schema exists, so return values need not be explained, and all three parameters are schema-documented. The description covers purpose and output shape well; the only minor gap is the absence of any when-to-use context versus the other conversion siblings.

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 'input', 'pages', and 'output' are already fully documented in the schema. The description adds no parameter-level detail (e.g., accepted path syntax), so the baseline 3 applies.

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?

Names a specific verb and resource (convert a PDF to a PowerPoint .pptx) and even specifies the output structure: one slide per page with editable text boxes. It does not explicitly differentiate itself from siblings like pdf_to_docx, so it falls 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?

There is no when-to-use guidance, no prerequisites, and no routing to alternatives such as pdf_to_docx or pdf_from_office. Usage is only inferable from the purpose statement, which calibration treats as insufficient for a 3.

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