delete-excel-range

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

Annotations already indicate destructiveHint=true, so the mutation is known. The description adds that content is shifted after deletion, revealing behavioral effect beyond the annotation, but lacks details on side effects like undo or permission requirements.

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 includes a tip, conveying key information efficiently. However, it uses informal language (e.g., '💡 TIP') which could be more structured for consistency.

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 no output schema, the description should explain what the tool returns or confirms after deletion. It covers the deletion action and shifting, but omits details on response behavior, prerequisites, or error conditions.

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?

The input schema includes a 'body' parameter with a 'shift' field but no description for shift. The description adds significant meaning by explaining valid values ('Up', 'Left') and their effect, making the parameter clearer.

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 'Delete cells at the given range' with specific action (delete) and resource (range). It distinguishes from sibling tools like clear-excel-range (which clears without shifting) and delete-excel-table-row (which targets a row).

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 provides a tip on using shift values 'Up' or 'Left' and suggests 'Up' for deleting rows, but does not explicitly state when to use this tool versus alternatives or when not to use it.

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