Update Groups Preferences

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

There are no annotations, and the description merely repeats the verb 'update' from the name. It does not disclose whether updates are partial or full, what permissions are required, how the target group is determined, or what side effects occur.

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 text is short but under-specified rather than genuinely concise. It simply repeats the title and provides no scope, parameters, or operational context, so the brevity adds no value.

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?

With no annotations, no parameter descriptions, and no clarification of scope or invocation semantics, this one-line description is far from complete. An agent cannot determine whether this acts on the current group, how the optional parameters interact, or what a successful update entails.

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 privateGroup, accept-language, or showAnnouncements. The schema provides only types with no explanatory text, so the description needed to compensate and did 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 Group Preferences' exactly restates the tool name and title, adding no new information about what updating the preferences entails. It also fails to distinguish this group-scoped tool from sibling tools such as update_households_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 is given about when to use this tool versus sibling preference endpoints like list_groups_preferences or update_households_preferences. There are no prerequisites, context cues, or exclusions.

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