get_services

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

No annotations are present, so the description must communicate behavioral traits. It only says 'List', which implies a read-only operation, but does not explicitly state that it is read-only, nor does it mention ordering, error conditions, or return format. The description offers minimal transparency beyond the obvious.

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 description is a single, front-loaded sentence that states the action and scope without any fluff. Every word contributes meaning, and it is perfectly sized for a tool of this simplicity.

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?

Given the zero-parameter nature and no output schema, the description provides adequate context: it names the domain (DataModel), lists examples, and makes clear the tool lists services. It could mention the return type or whether all services are returned, but for this complexity it is reasonably complete.

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 tool has zero parameters, so the schema fully covers everything. The baseline for 0 params is 4, and the description does not need to add parameter details. There is no semantic gap to compensate for.

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 uses a specific verb 'List' and resource 'all services currently in the DataModel', clearly distinguishing it from sibling tools like get_children or get_descendants. The examples (Workspace, ReplicatedStorage) add clarity.

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?

The description does not provide any guidance on when to use this tool versus alternatives. It lacks exclusions, prerequisites, or context for when get_children or get_descendants would be more appropriate. The use case is implied but not explicitly stated for decision-making.

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