excel_update_range

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

No annotations exist, so the description must disclose behavioral traits. It mentions routing and authentication but fails to describe the tool's actual behavior, such as destructive nature, required permissions, or effects on Excel data. Critical gaps for an update operation.

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 extremely short but wastes space on routing details and redundant phrasing. It misses substantive content that every sentence should earn its place.

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's complexity (update operation with opaque parameter) and the presence of an output schema, the description fails to explain the input semantics adequately. It is incomplete for effective tool use.

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% and the description only states that 'arguments' is a JSON string, without explaining its structure or expected fields. The agent has no guidance on how to construct valid input, making the parameter effectively unusable.

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 names the tool as 'update_range' for Excel, indicating a verb and resource. However, it does not elaborate on what updating a range entails (e.g., setting values, formatting), making it vague but not tautological. It is distinguishable from siblings like 'excel_get_range' but lacks specificity.

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 on when to use this tool versus alternatives like 'excel_get_range' or 'excel_add_worksheet'. No prerequisites, context, or exclusions are provided, leaving the agent without clear usage boundaries.

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