set_cell_vertical_alignment

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

With no annotations provided, the description carries the full burden. It states the action but does not disclose behavioral traits such as overriding existing alignment, error handling for invalid values (though it implies top/center/bottom), or whether the cell must exist. It is adequate but minimal.

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 concise sentence that efficiently communicates the tool's purpose and the valid alignment values, with no unnecessary words.

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 absence of parameter descriptions and the existence of an output schema, the description is incomplete. It lacks information on index formatting (e.g., zero-based), output details, and error conditions. It is adequate for a simple setter but leaves gaps for a new user.

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%, so the description must compensate. It adds meaning for the 'alignment' parameter by listing allowed values (top, center, bottom), but does not clarify the other three parameters (table_idx, row_idx, col_idx) beyond their names. Partial compensation.

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 tool's function: setting vertical alignment of a table cell, and lists the three allowed values (top, center, bottom). It distinguishes itself from sibling tools like set_table_alignment (table-level) or set_cell_shading.

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 does not provide explicit guidance on when to use this tool versus alternatives (e.g., set_table_alignment for table-level alignment). Usage is implied by the function name and description, but no when-not-to-use or prerequisite information is given.

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