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

With no annotations provided, the description carries the full burden of behavioral disclosure. While it describes the core functionality and return format, it lacks critical behavioral information: no mention of permissions required, rate limits, whether this is a synchronous or asynchronous operation, what happens with invalid inputs, or how errors are handled. The 'Returns' section describes output format but doesn't cover behavioral aspects.

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 well-structured with clear sections (Parameters, Available Layouts, Returns) but is overly verbose. The layout options list contains 15 items with detailed constraints that could be summarized more efficiently. The description mixes parameter documentation with implementation details that might be better placed elsewhere. However, the information is logically organized and front-loaded with the core purpose.

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?

Given the tool's complexity (4 parameters with nested structures) and complete lack of annotations and output schema, the description does a reasonably complete job. It documents all parameters thoroughly, explains the complex slides structure, provides layout constraints, and describes the return format. The main gaps are behavioral aspects (permissions, rate limits, error handling) and differentiation from sibling tools, but for parameter semantics it's quite comprehensive.

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 description provides extensive parameter documentation that fully compensates for the 0% schema description coverage. It explains all 4 parameters with clear semantics: 'template' (name/ID with reference to custom templates), 'language' (code examples), 'include_cover' and 'include_table_of_contents' (boolean purposes). Most importantly, it documents the complex 'slides' parameter structure with detailed layout constraints that aren't captured in the schema at all.

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's purpose: 'Generate a PowerPoint presentation using Slide-by-Slide input.' This specifies the verb ('generate') and resource ('PowerPoint presentation') with a specific method ('Slide-by-Slide input'). However, it doesn't explicitly differentiate from sibling tools like 'generate_powerpoint' - the distinction is implied but not stated.

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 no guidance on when to use this tool versus alternatives. There's no mention of when this 'slide-by-slide' approach is preferable over other presentation generation methods, nor does it reference the sibling 'generate_powerpoint' tool. The only contextual information is the tool name itself, which suggests a specific input method.

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