Manage Named Range

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

Annotations already declare the tool as mutating and destructive (readOnlyHint=false, destructiveHint=true), and the description's mention of delete is consistent. However, the description adds no further behavioral context such as irreversibility, permission requirements, or potential side effects on formulas or references.

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 compact sentence that front-loads the resource and verb, then efficiently enumerates the supported operations. There is no filler or redundant restatement of the tool name.

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 an eight-parameter, four-action tool, the description leaves action-specific parameter orchestration entirely to the schema. While the schema and output schema cover much of the needed detail, the description does not clarify identifier selection for update/delete or call out any action-specific constraints, making it incomplete for a tool of this complexity.

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 each parameter already has a meaningful explanation tying it to specific actions. The description itself adds no parameter-level detail, and a remaining ambiguity is that both name and named_range_id are described as optional identifiers for update/delete without clarifying precedence.

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 and resource, 'manages the lifecycle of named ranges in a Google Sheet,' and explicitly lists the four operations: list, create, update, or delete. This clearly distinguishes it from sibling sheet tools like read_sheet_values or manage_sheet_tab.

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 implies when to use the tool by naming named ranges as the resource, but it provides no explicit when-to-use guidance, prerequisites, or alternatives. An agent can infer the context, but there are no exclusions or comparisons to related sheet management tools.

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