add_table_start

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

With no annotations, the description must fully disclose behavior. It lacks information on whether existing content is shifted, if the tool requires an open document, or what happens if the document already has content at the start. The effect on the document structure is not explained.

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 sentence, which is concise but overly terse. It conveys the core purpose but omits necessary details. A slightly longer description that includes behavioral notes or parameter hints would be more helpful without being verbose.

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 tool has five parameters, no annotations, and no output schema, the description is far from complete. It does not mention return values, error conditions, or constraints on parameters like rows/cols being positive integers. The format of the 'data' array is unspecified.

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 coverage is 0%, meaning no parameter descriptions exist in the schema. The description does not explain any of the five parameters (doc_id, rows, cols, data, has_header_row). An agent has no understanding of what each parameter does from the description alone.

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 action ('Add a table'), the resource ('table'), and the location ('at the start of the document'). It effectively differentiates from sibling tools like add_table_end and add_table_at_paragraph by specifying the insertion point.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention that this inserts at the very beginning, whereas add_table_at_paragraph inserts at a specific paragraph or add_table_end inserts at the end. There is no context about prerequisites or suitability.

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