ViewUserRole

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

With no annotations provided, the description carries full burden for behavioral disclosure. While 'Get details' implies a read-only operation, it doesn't specify authentication requirements, rate limits, error conditions, or what 'details' include (e.g., role name, permissions, metadata). This is inadequate for a tool with zero annotation coverage.

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, efficient sentence that states the core purpose without unnecessary words. It's front-loaded with the essential action and resource, making it easy to parse quickly.

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?

For a read operation with no annotations, no output schema, and minimal parameter guidance, the description is insufficient. It doesn't explain what details are returned, potential errors, or system constraints, leaving significant gaps for the agent to infer behavior.

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 description mentions 'by ID', which aligns with the single 'id' parameter in the schema. However, with 0% schema description coverage, it doesn't clarify the ID format (e.g., numeric, UUID), source, or validation rules. The description adds minimal value beyond the bare schema, meeting the baseline for a single parameter.

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 clearly states the action ('Get details') and resource ('specific role by ID'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'ViewAllUserRoles' or 'ViewUserRolePermissions', which would require explicit comparison to earn a perfect score.

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 provides no guidance on when to use this tool versus alternatives like 'ViewAllUserRoles' or 'GetUserRoles'. It doesn't mention prerequisites, context, or exclusions, leaving the agent with minimal usage direction.

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