update_group_preferences

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

No annotations provided. The description only states 'Update', implying mutation, but fails to disclose any behavioral traits such as idempotency, authorization requirements, side effects, or whether partial updates are supported.

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 short (two lines), but this is under-specification rather than conciseness. It lacks any helpful context. The structure is minimal with a title and an HTTP endpoint line.

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 complexity of the tool (single body parameter with nested booleans), absence of annotations, and many sibling tools, the description is woefully incomplete. The agent cannot determine the effect of updating preferences, what values are allowed, or what the response will be.

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 0%, and the description does not mention any parameters. The input schema defines a body object with two boolean properties (privateGroup, showAnnouncements), but the description provides no explanation of their meaning or defaults. The agent cannot infer the semantics.

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 clearly states 'Update Group Preferences' which is a specific verb and resource, but it adds no value beyond the tool name. It does not distinguish from sibling tools like update_household_preferences or get_group_preferences.

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. There is no mention of prerequisites (e.g., being a group member) or when not to use it. The sibling get_group_preferences exists for reading, but no comparison is made.

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