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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, so the safety profile is covered. The description still adds real value by disclosing the device-state prerequisites and the shape of the result (identifiers usable as PIDs).

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?

Three short sentences, lead sentence front-loads the action and scope, and the workflow pointer is placed last. Nothing redundant.

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?

No output schema exists, yet the description tells the agent what comes back (process identifiers) and what constraints apply to the target device. Only the device_id format/derivation is left unexplained.

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 single parameter has 0% schema description coverage, and 'device_id identifies the target' essentially restates the parameter name. It conveys the param's role but not its expected format or how to obtain a valid id, leaving a real gap for a required identifier.

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 and resource ('List running processes and their identifiers') and scopes it to Windows/macOS devices, which cleanly distinguishes it from siblings like list_devices, list_services, and list_files.

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 the concrete precondition that the device must be registered, authorized and online, plus a downstream workflow cue ('Use the PID from results when calling kill_process'). It never states when NOT to use it or names a direct alternative lister, so it stops short of full routing guidance.

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