Insert Doc Elements

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true, so the description's 'inserts' adds little beyond confirming a write operation. It does not disclose behaviors like index validity constraints, whether insertion shifts existing content, or side effects of repeated calls at the same index — meaningful gaps for a mutation tool flagged openWorldHint=true.

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?

One front-loaded sentence with no filler; every word earns its place. It is slightly under-structured in that a brief clause pointing to an alternative sibling would have made it near-optimal, but as written it is efficient and scannable.

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?

The schema (100% coverage) and output schema carry parameter and return semantics, and annotations carry the safety profile, so the description is not obliged to repeat those. However, for an 8-parameter mutation tool with openWorldHint=true, the missing usage differentiation and insertion-behavior context leave noticeable gaps in what an agent needs to invoke it correctly.

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%, so every parameter (element_type, index, rows, columns, list_type, text, etc.) is already documented in the schema. The description's mention of tables/lists/page breaks mirrors the element_type enum values and adds no new semantic meaning, warranting the baseline 3.

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 uses a specific verb ('Inserts') and names the resource (Google Doc) plus concrete element types (tables, lists, page breaks), which distinguishes it from obvious text/image siblings like modify_doc_text and insert_doc_image. It does not, however, differentiate from overlapping doc siblings such as create_table_with_data and batch_update_doc, so it stops short of a 5.

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?

No explicit when-to-use/when-not-to-use guidance or alternatives are given. Given the dense sibling list with overlapping capabilities (create_table_with_data for tables, batch_update_doc for arbitrary doc updates), an agent gets no criteria for choosing this tool over those. Usage is only weakly implied by the description's purpose statement.

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