set_column_widths

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

The description adds useful behavioral context (unit in cm, array length constraint) but does not disclose whether this operation is destructive, requires a selected table, or returns any confirmation. With no annotations, the description carries the burden and falls short of full transparency.

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 sentence that conveys essential information without superfluous words, front-loading the action and critical constraint.

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?

Given the lack of annotations and the presence of an output schema (so return values need not be described), the description covers core functionality and constraints but misses details like prerequisites (table must exist) and the effect on existing widths.

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 0% description coverage; the description adds meaning to widths_cm (unit cm) and a constraint (length must match column count), but does not explain table_index (e.g., zero-based) or provide further details on the array elements.

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 clearly states the action 'set column widths', the resource (columns), and the unit (cm), distinguishing it from sibling tools like set_cell_width that focus on individual cells.

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 usage when setting all column widths at once with the constraint on array length, but lacks explicit guidance on when to choose this over alternatives like set_cell_width or set_table_alignment.

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