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

Annotations already declare readOnlyHint=true, so the safety profile is covered and the bar is lower. The description adds only the API mapping (GET /api/v1/roles); it says nothing about pagination behavior despite the next_token parameter, and nothing about whether results are tenant- or business-scoped beyond the phrase 'in the business'.

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?

Two short sentences, front-loaded with the purpose; nothing is padded. The endpoint reference is mildly redundant but harmless and cheap.

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?

A read-only list tool with fully documented parameters and annotations covering safety needs little more, and no output schema exists so return values need not be explained. Still, pagination semantics and the exact scope of 'roles' (vs. role permissions) are left unstated, leaving minor 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 100% – sort, page_size, and next_token are all documented in the schema with ranges and format hints. The description contributes no additional parameter meaning, so the baseline of 3 applies.

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?

States a specific verb and resource ('List the roles defined in the business') and even names the underlying endpoint, so the agent knows exactly what is returned. It does not, however, differentiate itself from adjacent siblings like kinde_list_role_permissions or kinde_list_permissions, which an agent could easily confuse with this one.

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 such as kinde_list_role_permissions or kinde_get_user_roles_in_organization. The description just states the operation; the agent must infer selection from the name alone.

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