wb_execute_file

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

Annotations indicate readOnlyHint=false, consistent with downloading a file (local write). However, the description does not disclose potential side effects (e.g., API quota usage, required permissions, or error handling). The minimal transparency relies entirely on annotations.

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 uses a bullet format for parameters, which is clear. However, it is under-specified; conciseness should not come at the expense of completeness. It is acceptable but not exemplary.

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 downloads a file and has an output schema, the description fails to mention return values, success/failure behavior, or file format. It also does not differentiate from sibling tools (wb_search, wb_execute). The context is incomplete for effective 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?

With 0% schema description coverage, the description must compensate. It lists parameter names and brief descriptions (action ID, local path, JSON params) but lacks details like valid action IDs, JSON format, or constraints. This adds minimal meaning beyond the schema's parameter names.

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 executes an action that downloads a file, specifying the verb and resource. It distinguishes from siblings like wb_search (search) and wb_execute (generic execution) by focusing on file download, though the distinction could be sharper.

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?

There is no guidance on when to use this tool versus alternatives, no prerequisites, and no context about appropriate scenarios. The description only states what the tool does, not when to use it.

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