spreadsheet_summarize_column

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states that the tool calculates statistics, which implies a read/analysis operation, but it does not disclose whether the spreadsheet is modified, what happens with non-numeric data, or other edge-case behaviors.

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, focused sentence with no filler or redundancy. It communicates the essential purpose efficiently and is appropriately front-loaded.

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?

The tool is relatively simple and has an output schema, so return value details are likely covered. However, the absence of parameter descriptions and explicit usage guidance leaves gaps: an agent may not know what 'basic statistics' includes or whether the tool mutates the spreadsheet. The description is adequate but 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 description must compensate for the undocumented parameters. It adds some meaning to 'column' by indicating it should be numeric, but it provides no additional detail about 'filename', 'sheet', or how the parameters relate to each other.

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 ('Calcula') and a clear resource ('estatísticas básicas de uma coluna numérica'). This clearly distinguishes it from siblings like spreadsheet_read_range or spreadsheet_update_cell, making the tool's purpose immediately identifiable.

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 when the tool should be used by specifying 'coluna numérica' (numeric column), which is a prerequisite condition. However, it does not explicitly state when to choose this tool over alternatives such as spreadsheet_read_range, nor does it mention exclusions.

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