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

readOnlyHint=true already establishes that this is a safe read, so the bar is lower, but the description adds almost nothing behavioral: no mention that results are paginated via next_token, no indication of permission/auth requirements, and no note about ordering defaults. Only the tenant-wide '(business)' scope is a mild addition.

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, purpose front-loaded, nothing superfluous. The endpoint reference is compact metadata rather than padding, and there is no filler prose.

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?

With no output schema, the description could reasonably say more about what a permission record contains and how paging should be driven, but the parameters are fully self-documented. It is adequate but minimal for a tenant-wide list endpoint.

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% and all three optional parameters (sort, page_size, next_token) are documented in the schema with ranges and semantics, so the baseline of 3 applies. The description adds no extra meaning about parameter behavior or defaults.

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+resource ('List the permissions defined in the business') and even names the backing endpoint, so the agent knows exactly what is returned. It does not explicitly distinguish itself from close siblings such as kinde_list_role_permissions or kinde_list_organization_users, so it falls short of a 5.

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 gives no when-to-use guidance, no prerequisites, and no pointer to alternatives like kinde_list_role_permissions for role-scoped permissions. Usage is only implied by the verb 'List'.

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