update_ranger_user

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

With no annotations, the description carries full burden. It correctly labels the operation as write, but does not disclose side effects (e.g., partial vs full update, audit logging) or what the response contains despite an output schema existing.

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 very short (one sentence plus bold note), which is concise but omits essential details. It is front-loaded with the action and resource, but lacks structural elements like parameter explanations.

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 2 required parameters, 0% schema coverage, no annotations, and an available output schema, the description should provide more context. It does not mention the output or how the JSON input relates to existing user attributes.

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 0%. The description does not explain the parameters user_id and user_json beyond their names. user_json could be ambiguous (JSON string with fields to update? Full user object?). No detail on format or required fields.

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?

Description clearly states the verb 'Update' and the resource 'Ranger user'. The bold 'WRITE OPERATION' further emphasizes the action. It is distinguishable from sibling CRUD tools like create_ranger_user and delete_ranger_user.

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 (e.g., create vs update). No prerequisites mentioned, such as needing the user to exist or the JSON format expected.

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