trmm_agent_services

Read-onlyIdempotent

Check Windows services on a specific agent. Filter by name substring or running/stopped state to retrieve only relevant entries without loading the full large list.

Instructions

Windows services on an agent. Filter by name substring or state (running/stopped) to avoid pulling the whole list, which is large.

Behavior4/5

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

The description adds useful behavioral context beyond the annotations by explaining that the response can be large and that filtering is encouraged to avoid pulling the entire list. This helps the agent anticipate cost/scale and choose appropriate parameters. The read-only and non-destructive annotations are consistent with the description.

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

Conciseness5/5

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

Two sentences convey the resource, scope, filtering options, and an important performance consideration with no wasted words. The key subject is front-loaded and the guidance is immediately actionable.

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 simple read-only list tool, the description covers the essential context: what is being queried, how to filter, and why filtering matters. The lack of an output schema is mitigated by the tool's straightforward nature, though the 'limit' parameter semantics would add completeness.

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

Parameters3/5

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

With 0% schema description coverage, the description carries the burden of explaining parameters. It usefully maps 'search' to name substring and 'state' to running/stopped. However, it does not explain the 'limit' parameter or clarify 'agent' beyond the phrase 'on an agent', so coverage is only partial.

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?

The description clearly identifies the resource as 'Windows services on an agent' and distinguishes it from sibling agent-focused tools like processes, event log, and software. It lacks an explicit verb like 'List' or 'Get', but the filtering guidance makes the retrieval intent clear.

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?

The description gives practical guidance on using filters ('Filter by name substring or state') and warns that the full list is large. However, it does not explicitly state when to prefer this tool over alternatives or when not to use it, leaving sibling differentiation mostly implicit.

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