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 mentions 'inspect,' implying a read-only operation, but fails to detail aspects like authentication requirements, rate limits, error handling, or what the inspection entails (e.g., schema format, metadata). This leaves significant gaps in understanding the tool's behavior.

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, direct sentence that efficiently conveys the core purpose without unnecessary words. It is front-loaded with the main action and resource, making it easy to grasp quickly, which is ideal for conciseness.

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 that there is an output schema (which likely describes the return values), the description does not need to explain outputs. However, with no annotations, low parameter coverage, and multiple sibling inspection tools, the description lacks sufficient context on usage, parameters, and behavioral traits, making it only minimally adequate for a simple tool.

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 has 0% description coverage, and the tool description does not explain the 'target_source' parameter beyond implying it refers to an Excel datasource. No details on format, examples, or constraints are provided, failing to compensate for the schema's lack of documentation and leaving the parameter's meaning unclear.

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 ('inspect') and resource ('first-sheet schema of a target Excel datasource'), making the tool's function evident. However, it does not explicitly differentiate itself from sibling tools like 'inspect_csv' or 'inspect_hyper', which also inspect data sources, leaving room for ambiguity in tool selection.

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 no guidance on when to use this tool versus alternatives, such as 'inspect_csv' or 'inspect_hyper', nor does it mention prerequisites or context for its application. This lack of usage instructions could lead to confusion in tool selection among similar inspection tools.

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