List Kernel Modules

list_kernel_modules

Read-onlyIdempotent

Lists loaded kernel modules and drivers on managed systems, enabling agents to inspect OS state for inventory, diagnostics, and deployment troubleshooting.

Instructions

List loaded drivers/modules (lsmod or driverquery).

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered elsewhere. The description adds the OS-command equivalence (lsmod on Linux, driverquery on Windows), which conveys that results are platform-dependent, but says nothing about return shape or whether results include unloaded/built-in modules. With an output schema present, that gap is tolerable.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The operative sentence is front-loaded and wastes no words. The trailing 'CONCEPT:SM-OS.deployment.deep-introspection-telemetry' tag is metadata noise from an agent's perspective but is short enough not to harm the definition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter read-only listing with annotations covering the safety profile and an output schema covering return values, the description supplies enough to call it correctly. Only minor detail about scope (e.g. built-in vs loaded modules) is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a parameterless tool applies. The description correctly implies no inputs are needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: 'List loaded drivers/modules', which is unambiguous and clearly distinct from siblings like get_process_details or list_services. It does not explicitly name a sibling to differentiate against, but the resource is narrow enough that confusion is unlikely.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Loaded drivers/modules' implies the diagnostic context in which you'd call it (driver inspection, kernel-level troubleshooting), and the lsmod/driverquery reference anchors it to a known operation. There is no explicit when-to-use or when-not-to-use statement, and no alternative tool is named.

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