Create Word Document

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

Annotations already indicate destructiveHint=true and readOnlyHint=false, so agent knows it's a write operation. Description adds 'Create' and file path requirement but does not disclose potential file overwrite or permission needs. No contradiction.

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?

Description is compact with clear sections (Args, examples). Every sentence adds value, no redundancy. Well-structured for agent parsing.

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 4 parameters, nested objects, and no output schema, description adequately explains inputs and purpose. Examples cover common use cases. Slight gap: no mention of return value or error scenarios, but acceptable.

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 coverage is 100% with descriptions for all parameters. Description adds human-readable explanation of the 'contents' array structure and optional parameters like title and author, providing beyond-schema value.

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?

Description clearly states 'Create a new Word (.docx) document' with specific verb and resource. It lists supported content types (headings, paragraphs, lists, tables) and distinguishes from sibling tools for Excel, PowerPoint, etc.

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?

Provides 'Use when:' examples like 'Create a report document with headings and bullet points' which gives clear context. Lacks explicit when-not-to-use or alternative tools, but sibling tool names imply differentiation.

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