Workspace.Sheets.Read Range

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

No annotations are provided, but the verb 'Read' strongly implies a non-destructive operation, and an output schema exists so return values are covered elsewhere. The description omits permission/scope requirements, behavior on empty or out-of-bounds ranges, and any size/rate limits, which leaves real gaps for a no-annotation tool.

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?

A single tight sentence with the key format detail front-loaded; no filler. It is arguably too terse rather than too verbose.

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?

Return values are covered by the output schema, so the description needn't explain them. But for a 2-param tool with zero schema description coverage, it should at minimum say how to obtain spreadsheet_id and what a valid A1 range looks like; that omission leaves it only minimally complete.

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?

With 0% schema description coverage, the description must compensate and it partially does: it clarifies that range_a1 uses A1 notation. However, it says nothing about where spreadsheet_id comes from (Drive listing, URL) or its format, leaving half the parameter meaning unaddressed.

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 ('Read a cell range ... from a spreadsheet') and specifies the A1 notation format. It is clearly distinguishable from write_range by the verb, but the description never names siblings or explicitly contrasts with get_metadata/write_range.

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?

There is no guidance on when to use this versus get_metadata or write_range, no prerequisites (e.g., needing a spreadsheet_id first), and no exclusions or error conditions (invalid range, missing sheet).

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