create_table

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

No annotations are provided, so the description carries the behavioral burden. It discloses that a Table/ListObject is created and that 'backup' can create a backup before modifying the workbook, but doesn't state what happens on existing ranges (e.g., conversion of data, overwrite of formatting) or permission preconditions. Some value, but incomplete for a mutation tool with no annotations.

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 front-loaded with the core action and then uses a structured Args block. It is efficient and each parameter note earns its place, though the list format is a bit text-heavy for what could be a tighter sentence, and 'formal' is slightly redundant with ListObject.

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 8 parameters, mutation semantics, and no annotations, the description covers required inputs and behavior of each optional flag. It omits return value details, but since an output schema exists that burden is lifted. It still lacks error or conflict conditions (e.g., duplicate table_name), so not fully complete.

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 Args list is the only documentation of parameters. It meaningfully explains every parameter: path preloaded-file behavior, table_name uniqueness across the workbook, style_name example, show_filter dropdowns, show_row_stripes shading, and backup behavior—this compensates fully for the empty schema text.

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?

States a specific verb and resource ('Create a formal Excel Table (ListObject)'), and ties it to a concrete location ('on the specified range'). This cleanly distinguishes it from table-modifying siblings like write_cells or set_cell_style, and the ListObject terminology removes ambiguity about what entity is produced.

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 through required ranges and table naming, but gives no explicit when-to-use or when-not-to guidance, no prerequisites (e.g., sheet must exist, range must be contiguous), and does not reference alternatives. Adequate but leaves the agent to infer timing.

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