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

No annotations are provided, so the description carries the full behavioral burden. It implies a destructive mutation but does not state whether removal is reversible, what happens to the removed member, what permissions are required, or any side effects; only the ownership precondition is hinted at.

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?

A single compact sentence with the scope qualifier front-loaded and no wasted words. It is appropriately sized, though its brevity contributes to the behavioral gaps noted elsewhere.

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 destructive mutation tool with no annotations and no output schema, the description is too thin: it omits reversibility, permission requirements, error conditions (e.g., tenant not a member), and any confirmation semantics an agent would need before calling it.

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%, so the schema already documents all three parameters including the tenant_key authorization nuance. The description adds only a light restatement ('by namespace'), which does not exceed the schema baseline.

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 ('Remove') and resource ('a tenant ... from a group'), with the qualifier 'this tenant owns' narrowing scope. An agent can distinguish it from host.group.add and host.group.create from the verb alone, though no sibling is named explicitly.

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 phrase 'a group this tenant owns' implies a precondition (ownership) that gates legitimate use, but there is no explicit when-to-use guidance and no alternative sibling (e.g., host.group.list or host.group.add) is referenced for the inverse operation.

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