TDQS

C2.9/5.0

Behavior2/5

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

Annotations already declare readOnlyHint=true, and the description merely repeats '(read-only)', adding no new behavioral facts. 'Compact fields' is a thin hint at return breadth, and since an output schema already exists that detail is largely redundant. No mention of auth requirements or whether groupId/shortCode is required to scope the call.

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?

A single front-loaded sentence with the verb, resource, output shape, and safety profile all packed in without filler. Nothing could be trimmed without losing content.

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

Completeness3/5

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

The presence of an output schema and a read-only annotation means return values and safety are covered, so the description needn't restate them. However, with three parameters at 0% schema coverage and an ambiguous id-or-shortCode scoping model, the definition leaves real gaps an agent must guess at.

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

Parameters2/5

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

Schema coverage is 0%, so the description carries the full burden, yet it never mentions the 'view', 'groupId', or 'shortCode' parameters. The phrase 'roles or role templates' faintly mirrors the view enum, but it does not explain that the query must be scoped by groupId or shortCode nor which is preferred when both exist.

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 pairs the verb 'List' with the specific resource 'group roles or role templates' and notes the output shape ('compact fields'). It is separable from the mutating sibling vrchat_group_roles_manage primarily through the explicit '(read-only)' marker rather than through naming the counterpart, so it is clear but not strongly differentiated.

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

Usage Guidelines2/5

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

The description gives no when-to-use guidance, does not name vrchat_group_roles_manage as the write-path alternative, and says nothing about when to query roles versus templates beyond restating the enum values. An agent must infer scoping and selection logic entirely on its own.

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