Get Custom Role

get_custom_role

Read-onlyIdempotent

Read a custom_role record. MCP approval requirements are configurable by the organization administrator; business workflow approvals always apply.

B3/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false, and destructiveHint=false, so safety behavior is covered. The description adds approval-related context, though it is generic and does not clarify tool-specific behavior such as error handling or authorization details.

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

Conciseness3/5

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

The first sentence is concise and front-loaded. The second sentence is short but reads as generic approval boilerplate that may not earn its place in a read-only lookup tool's description.

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 one-parameter read tool with rich annotations and an output schema, the description is largely sufficient. The main gap is the lack of explicit parameter semantics and sibling differentiation, but the core operation is clear.

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 description coverage is 0%, and the description never mentions the required id parameter or what kind of identifier it expects. The parameter name and UUID format make it inferable, but the description does not compensate for the missing schema documentation.

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 states a specific verb ("Read") and resource ("custom_role record"), and the singular "record" implies a single-item lookup. However, it does not explicitly mention retrieval by ID or differentiate from sibling tools like list_custom_role.

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?

There is no guidance on when to use this tool rather than list_custom_role or update_custom_role. The second sentence concerns approval requirements, not usage selection.

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