set_column_width

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states that the width is set, with no mention of potential side effects, whether the change is reversible, scope constraints, or permission requirements. 'Set' implies mutation, but nothing else is disclosed.

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 efficient sentence with a helpful example. It is front-loaded with the action and target, and every word adds value with no redundancy.

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?

This is a relatively simple mutation tool, and the description covers the key action and format details. Still, with no annotations and no output schema, it omits side-effect expectations, success/error behavior, and the meaning of the optional 'sheet' parameter, leaving clear 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 description coverage is 0%, but the description adds useful meaning for 'columns' ('A' or 'A:E') and 'width_cm' (cm). However, it leaves 'sheet' unexplained even though it accepts string, integer, or null, and it does not clarify the role of 'doc_id' beyond its name.

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 states a specific verb ('Set'), the resource ('column or column span'), and the unit ('cm'), with a concrete syntax example ('A' or 'A:E'). This makes the tool's purpose unambiguous and clearly distinct from related sibling tools like style_cells or set_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?

There is no guidance about when to use this tool versus alternatives, nor any exclusions or prerequisites. The only usage signal is implied by the name and description, which is not enough for an agent to decide between this and similar editing tools.

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