copy_to_windows

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

Adds real context beyond the annotations: binary-file support, the existence and role of the staging folder, and the server-side precondition that the feature is disabled without one. Since destructiveHint=true, it would be stronger if it disclosed overwrite behavior when 'name' collides with an existing staged file, which is the main unstated risk.

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?

Purpose and precondition are front-loaded in the first two sentences, and the parameter notes are compact. The two inline parameter lines are a slightly clunky structure but every line carries information.

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. Coverage of purpose, precondition, binary support, and both parameters is sufficient for correct invocation; only failure/overwrite behavior is missing.

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 carry the burden, and it mostly does: 'path' is identified as the file in WSL, and 'name' is explained as a file name or sub/path inside the staging folder with the empty-default behavior spelled out ('empty keeps the file's own name'). Only the accepted path syntax (absolute vs relative, backslash vs forward slash) is left unaddressed.

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 (copy) plus the exact resource and direction: a WSL file into the Windows staging folder. It further narrows scope with binary formats (docx, pdf, png, .skill), which makes it trivially distinguishable from the sibling copy_from_windows and the read/write_file family.

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?

Gives clear usage context (use it so 'your own file tools can open' the file) and an explicit precondition: 'Off unless the server has a staging folder set.' It does not explicitly name copy_from_windows as the counterpart for the reverse direction, so routing is implied by naming rather than stated.

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