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

With no annotations, the description carries the burden. It discloses that the tool is a shim and dispatches to the single-verb tools, which is a clear behavioral trait. However, it doesn't explain how the 'operation' parameter maps to those tools or any side effects, but for a deprecated shim this is reasonably transparent.

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 concise, front-loaded with 'DEPRECATED', and lists the replacement tools in a readable structure. Every sentence adds value; there is no filler.

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?

The description excels as a deprecation notice but falls short as an operational spec. It lacks any parameter semantics for a 5-parameter tool, so an agent needing to invoke the shim directly would be under-informed. The output schema exists, so return value details are not needed, but the invocation contract is incomplete.

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 description coverage is 0% and the description provides no additional parameter information. The five parameters (file_id, file_path, operation, sheet_name, spreadsheet_id) are unexplained, and the description does not map them to the dispatched tools. This is a critical gap since the agent cannot know valid values for 'operation' or how other parameters combine.

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 it is a deprecated backward-compatibility shim that dispatches to four named single-verb tools (list/get/upload/delete). This distinguishes it from its siblings and tells exactly what it does, so purpose is unambiguous.

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 explicitly says 'DEPRECATED — use workiva_wdata_list_files / workiva_wdata_get_file / workiva_wdata_upload_file / workiva_wdata_delete_file.' This gives direct when-to-use (avoid) and names the alternatives, fulfilling the usage guideline criterion completely.

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