create_client

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

No annotations are provided, so the description must convey behavioral traits. It only states 'create', implying mutation, but does not disclose side effects, required permissions, or any other behavioral aspects. Significant gap for a write operation.

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 a single, short sentence with no redundant information. It communicates the core purpose efficiently, earning its place without waste.

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?

Given the tool has no output schema and a nested object parameter (client_data), the description is too terse. It should explain what the tool returns (e.g., created client ID) and provide guidance on client_data structure. The current description leaves the agent underinformed.

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 coverage is 100%, meaning both parameters are described in the schema (realm: string, client_data: object). The description adds no additional meaning beyond the schema. Baseline is 3, as the schema already provides basic parameter info.

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 'Create a new client in the realm' uses a specific verb ('create') and resource ('client'), clearly stating the action. It effectively distinguishes the tool's purpose from sibling tools that operate on other entities like scopes or roles.

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 provides no guidance on when to use this tool versus alternatives (e.g., create_client_scope, create_client_role). No mention of prerequisites, context, or when not to use it. With many sibling tools, such guidance is crucial.

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