inspect_excel_connection

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

With no annotations, the description carries the full behavioral burden. "Preview" hints at a non-mutating inspection, but it never states whether the file must exist, what permissions are required, whether anything is written, or what interpretation decisions are surfaced. This is thin for a tool whose whole value is diagnostic output.

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?

A single front-loaded sentence with no filler or redundancy. It is efficient, though the terseness is part of why the other dimensions are weak.

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?

An output schema exists, so return values need not be described, but the description still omits the parameter meanings and any behavioral context for a tool with zero annotation coverage. For a pre-flight inspection tool, the agent is left guessing what is inspected and under what 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?

Schema coverage is 0% and neither parameter is mentioned in the description. file_path is at least inferable from its name, but sheet_name's empty-string default and its role in scoping the preview are entirely undocumented in both the schema and the description.

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 ("Preview") and resource ("how an Excel workbook will be interpreted"), and the phrase "before connection setup" implicitly positions it as the dry-run counterpart to set_excel_connection. It stops short of naming that sibling explicitly, but the purpose is clear enough to distinguish it from actual connection creation.

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?

"before connection setup" gives an implied timing/context for use, so the agent can infer it precedes set_excel_connection. However, there is no explicit when-to-use statement, no when-not-to-use, and no named alternative, leaving the routing decision partly to inference.

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