Create list in Google Doc

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

Annotations already declare readOnly=false, destructive=false, idempotent=true, so safety is covered. The description adds substantive behavior beyond that: consecutive paragraphs merge into one list, leading tabs become nesting levels and are removed, which shifts later indexes while otherwise indexes are unchanged. Auth/permission and error behavior are not covered.

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?

Three dense sentences, front-loaded with the core action, then the listType options and default, then the new-content workflow and index-shift caveat. Every clause carries information; there is no filler.

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 non-destructive, idempotent mutation tool with no output schema, the definition covers purpose, options, workflow, and index side effects well. It does not mention permissions/scope requirements or what the call returns, leaving minor gaps.

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%, so baseline is 3. The description adds meaning beyond the schema: it explains the nested-file default for listType, the '1., a., i.' numbering forms, and—most importantly—that leading-tab characters in the target paragraphs drive nesting levels, which is not captured in any parameter 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?

States a specific verb and resource: turning paragraphs in an index range of a Google Doc into list items. It names concrete variants (bulleted/numbered/checkbox) and is easily distinguished from siblings like format_text or set_paragraph_style, which don't create list structure.

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?

Gives clear context for use and a workflow: to build a list from new content, append/insert the items as newline-separated lines first, then call this with their range. It also points to get_document for obtaining indexes. No explicit exclusions or when-not-to-use against specific siblings, so slightly short of 5.

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