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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions 'Inserts' which implies a write operation, but fails to detail behavioral traits like required permissions, rate limits, error handling, or the effect on the document (e.g., whether insertion shifts existing content). 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 a single, efficient sentence that directly states the tool's function without unnecessary words. It is front-loaded with the core action, making it easy to grasp quickly. However, it could be slightly more structured by including key details like supported element types explicitly, but overall it is concise and well-formed.

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 (8 parameters, mutation operation) and the presence of an output schema (which reduces need to explain return values), the description is minimally adequate. However, with no annotations and a write operation, it should provide more context on behavior and usage to be fully complete, leaving room for improvement despite the output schema.

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%, meaning all parameters are documented in the schema itself. The description adds no additional semantic context beyond what the schema provides (e.g., it doesn't explain parameter interactions or provide examples). Thus, it meets the baseline score of 3, as the schema handles the heavy lifting without extra value from the description.

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 verb ('Inserts') and resource ('structural elements like tables, lists, or page breaks into a Google Doc'), making the purpose evident. However, it does not explicitly differentiate from sibling tools such as 'insert_doc_image' or 'insert_doc_link', which handle different types of insertions, so it misses full sibling differentiation.

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, such as other insertion tools in the sibling list (e.g., 'insert_doc_image' for images). It lacks context about prerequisites, dependencies, or scenarios where this tool is preferred, offering only a basic functional statement without usage context.

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