set_print_area

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

Annotations already disclose destructiveHint=true, and the description adds the 'or clear' behavior, which clarifies the tool can both set and remove the print area. However, it does not detail other behavioral aspects like whether existing settings are overwritten or what happens when `range_ref` is null. This exceeds the baseline for annotation-only transparency but remains limited.

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 short sentence, highly efficient and easy to parse. It front-loads the core action with no filler, though its brevity sacrifices explanatory depth.

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?

With 5 parameters, no output schema, and only a destructive annotation, the description is far from complete. It omits when to use the tool, parameter semantics, side effects, and expected outcomes, leaving significant gaps for an agent attempting 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?

The schema has zero descriptions, and the description's 'Set or clear' does not explain any parameter meanings. Parameters like `range_ref`, `include_changes`, and `dry_run` are left entirely undefined, and the description fails to compensate for the 0% schema coverage.

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 the clear verb 'Set or clear' paired with the specific resource 'worksheet print area,' which immediately distinguishes it from sibling tools like `set_print_titles` and `freeze_panes`. It unambiguously communicates the tool's primary function.

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 `set_print_titles` or `format_range`. There is no mention of prerequisites, contexts, or exclusions, leaving the agent without direction on choosing this tool.

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