format_table_cell

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

The annotations provide only a title and no readOnlyHint or destructiveHint, so the description carries the burden of explaining side effects. It implies that the tool modifies a cell's formatting but does not disclose whether it overwrites existing formatting, whether null values keep settings unchanged, or what permissions or side effects apply. This is minimal behavioral disclosure.

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 short and front-loaded, but it is under-specified rather than appropriately concise. It essentially restates the tool name and title without providing the additional structural or semantic information an agent needs for a tool with this many parameters.

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?

For a 13-parameter tool with no schema descriptions and no annotations beyond a title, the description is far from complete. It does not clarify how to identify the cell, how to specify formatting values, what value formats are expected, or what the tool does beyond the broad verb 'format.'

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%, and the description mentions none of the 13 parameters. It does not explain required parameters like slide_index, shape_index, row, and col, nor optional formatting fields such as alignment, color, font_size, or vertical_alignment. With no parameter information anywhere, the agent cannot derive how to invoke the tool correctly.

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, 'Format a specific table cell,' names a clear verb and resource, and the phrase 'specific table cell' narrows the target to one table cell rather than a presentation, slide, or whole table. It is distinguishable from siblings like add_table and manage_text at a high level, though it does not say anything about what kinds of formatting are supported.

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 tool versus alternatives such as manage_text, manage_fonts, or format_chart_series. The description provides no context, preconditions, or exclusions, leaving the agent to infer when this tool is appropriate.

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