sec_userRoles

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

No annotations provided. The description does not disclose whether the tool is read-only, what permissions are required, or how errors (e.g., missing user) are handled. The return format is vaguely described as 'formatted response with query results + metadata', which is insufficient.

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 concise with two sentences plus a structured arguments/returns section. However, the arguments/returns section partly duplicates the schema and could be integrated more efficiently.

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 tool with one parameter and no output schema, the description is barely adequate. It lacks details on data source, role semantics, and error behavior. It meets minimal requirements but leaves gaps.

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?

Schema description coverage is 0%, so the description bears the burden. It adds 'to analyze' to the parameter, providing slight context, but does not elaborate on expected input format or constraints. Baseline is low but description adds marginal value.

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 tool retrieves roles for a user. The verb 'Get' and resource 'roles assigned to a user' are specific. Among siblings like 'sec_rolePermissions' and 'sec_userDbPermissions', this tool's purpose is distinct.

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?

No guidance on when to use this tool versus alternatives like 'sec_rolePermissions' or 'sec_userDbPermissions'. The description lacks context on prerequisites or use cases.

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