Create Doc

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

Annotations indicate the tool is not read-only, destructive, or idempotent. The description adds behavioral context beyond annotations by detailing the initial state of the document (index positions, length) and implying it is a creation operation without side effects. No contradiction with annotations.

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 7 sentences, front-loaded with the purpose. Each sentence adds useful information without redundancy. It could be slightly more concise, but the structure is logical and easy 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 creation tool with 3 parameters and an output schema, the description covers purpose, initial state, and post-creation workflow. It is sufficiently complete for an agent to understand how to use the tool and what to do next.

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. The description adds value by noting the content parameter is optional and explaining how it relates to the document's initial structure. This goes beyond the schema's field descriptions.

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 'Creates a new Google Doc and optionally inserts initial content.' This is a specific verb+resource combination that distinguishes create_doc from sibling tools like create_drive_file, create_form, and create_presentation.

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 actionable workflow guidance, explaining the initial document structure (body starts at index 1, total length 2) and recommending subsequent steps: use batch_update_doc with end_of_segment=true, then inspect_doc_structure before formatting. This helps the agent understand the sequence of operations.

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