Household List Household Members

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior, so the safety profile is covered. The description adds no extra behavioral details beyond the basic listing action, such as return shape or scope, but it does not contradict the annotations.

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 extremely concise and front-loaded: 'List household members.' It contains no wasted words, though it is brief enough that some contextual information is pushed to other sources.

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 simple list operation with optional parameters and rich annotations, the description is minimally adequate. However, with no output schema and no mention of return format, ordering, or member scope, it leaves some ambiguity for an agent deciding whether full details are returned or just a summary.

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 fields and output_mode are already well documented in the input schema. The description does not add additional parameter context, which is acceptable given the schema carries the burden.

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 states a clear verb and resource: it lists household members. It is unambiguous and distinguishable from the singular sibling household_get_household_member, though it does not explicitly compare itself to related household tools.

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 context about when to use this tool versus siblings like household_get_household_member or household_get_current_user. There is no guidance on prerequisites, intended use cases, or when an alternative would be more appropriate.

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