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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the operation saves to disk and returns a status, but lacks details on permissions needed, file format (e.g., .pptx, .pdf), error handling, or whether it overwrites existing files. For a write operation with zero annotation coverage, this leaves significant gaps in understanding the tool's behavior.

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 efficiently structured with a clear purpose statement followed by Args and Returns sections. Every sentence adds value: the first defines the action, and the subsequent lines explain parameters and output without redundancy. It's appropriately sized for a tool with two parameters and an output schema.

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 has an output schema (which handles return values) and moderate complexity (2 parameters, no nested objects), the description is minimally adequate. However, as a write operation with no annotations, it should ideally include more behavioral context like file system interactions or error conditions. The presence of an output schema raises the baseline, but gaps remain in operational transparency.

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 0%, so the description must compensate. It adds meaningful context for both parameters: 'presentation_id' is explained as 'ID of the presentation', and 'path' is clarified as 'Optional path to save the file (if None, save to current location)'. This provides practical usage information beyond the bare schema, though it doesn't specify path format (absolute/relative) or validation rules.

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 with 'Save a presentation to disk', specifying both the verb (save) and resource (presentation). It distinguishes from siblings like 'create_presentation' or 'open_presentation' by focusing on saving to storage. However, it doesn't explicitly differentiate from potential file export tools that might exist elsewhere.

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. It doesn't mention prerequisites (e.g., whether the presentation must be open or created first), nor does it compare with sibling tools like 'close_presentation' or 'update_text' for related operations. Usage context is implied but not explicitly stated.

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