usergroups_users_update

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

The description lacks behavioral details beyond 'update'. It does not clarify that the tool replaces the entire user list, nor does it disclose side effects, authorization needs, or what happens to users omitted from the list. With no annotations, the description should provide 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, which is concise but lacks necessary detail. It front-loads the purpose but omits key behavioral and contextual information. It could include more in the same space.

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 has 6 parameters, no annotations, and is a mutation with an output schema, the description is incomplete. It fails to explain key behaviors like replacement semantics, required parameters, or usage context for parameters like team_id and is_shared.

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 coverage is 100%, so the baseline is 3. The description adds no extra meaning beyond the schema's parameter descriptions. It merely restates 'list of users', which is already captured in the schema.

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 the list of users for a User Group', which specifies the verb (update) and resource (list of users for a User Group). It distinguishes from sibling tools like usergroups_update (which updates group properties) and usergroups_users_list (which lists users).

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 that the list is replaced wholesale, nor does it describe prerequisites or scenarios where other tools (e.g., usergroups_users_list) might be more appropriate.

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