win_get_disk_space

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

With no annotations, the description carries the full burden but only implies a read operation. It does not state whether credentials are required (despite the sibling win_setup_credentials), what happens if the host is unreachable, or what the returned disk-space data includes.

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 single sentence is front-loaded and free of waste. However, its brevity borders on under-specification rather than efficient 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?

For a tool with no annotations, no output schema, and an undocumented required parameter, the description leaves critical context missing. An agent cannot determine authentication needs, failure behavior, or return shape from this definition alone.

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 only parameter, hostname, has no documented format in either schema or description. The description implies hostname identifies the Windows host but does not clarify whether it expects an FQDN, IP address, or credential reference.

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 states a specific verb (Get) and resource (disk space information) scoped to a Windows host. It is distinguishable from win_get_running_services or win_get_system_info at a glance, though it does not explicitly name those siblings as alternatives.

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 win_get_system_info or win_execute_powershell, and no prerequisites such as credential setup or host reachability are mentioned. Usage is only implied by the phrase 'from Windows host.'

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