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

Annotations carry only destructiveHint=true, so the description must bear most of the behavioral burden. It adds only the raw endpoint (POST /api/v1/organization) and says nothing about required auth/scopes, what happens with duplicate names or external_id, or what is returned. No contradiction with the mutation annotation, but very thin disclosure for a write tool.

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 compact sentences, front-loaded with the action and resource, with no filler. The trailing API-endpoint restatement is redundant but small.

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 create tool with no output schema and minimal annotations, the description omits the returned organization identifier and error behavior, which the agent needs to chain into siblings like kinde_add_users_to_organization. The surviving gaps are significant given how little structured data compensates.

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%, with name, external_id, and feature_flags all documented in the schema. The description adds no parameter-level meaning (e.g., external_id uniqueness or feature-flag value format), so the baseline 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 ('Create a new organization'), and usefully disambiguates the domain term with '(tenant)'. It is clearly distinguishable from create_permission/create_role by resource, though it does not explicitly contrast with any sibling.

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?

There is no guidance on when to create an organization versus using an existing one, no prerequisites, and no mention of alternatives such as kinde_get_organization or kinde_list_organizations. The agent must infer usage entirely.

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