update_household_preferences

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

No annotations are provided, and the description does not disclose behavioral traits such as side effects, permissions needed, or what happens on success/failure. For a mutation tool, the description should note that preferences are overwritten, but it lacks this context.

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 sentence, making it concise, but it lacks structure and front-loading of critical information. It includes the endpoint but no additional useful data. It is adequate but not well-structured.

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's complexity (9 parameters, no output schema, no annotations), the description is severely incomplete. It does not explain return values, valid values for parameters, or any behavioral context. The agent lacks sufficient information to use the tool correctly.

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?

The input schema has 9 boolean parameters with defaults, but the description provides no explanation of what each preference controls. With schema description coverage at 0%, the description should compensate by describing the purpose or effect of key parameters, but it does not.

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 'Update Household Preferences' clearly states the verb (update) and resource (household preferences), making the tool's purpose unambiguous. It distinguishes from the sibling 'get_household_preferences' which is a read operation.

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 is provided on when to use this tool versus alternatives. It does not mention prerequisites, such as whether the household must exist or whether the user has permissions. The description offers no contrast with sibling tools like 'update_group_preferences' or 'get_household_preferences'.

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