users_bulk_update_squads

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

With no annotations provided, the description carries the full burden of explaining behavior. It only says 'update', which implies mutation, but does not disclose whether the assignment is additive, replacement-based, whether it affects existing assignments, permission requirements, or any side effects. The behavioral surface remains largely opaque.

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 front-loaded sentence with no filler or redundancy. It wastes no words and efficiently conveys the core action, though it sacrifices important behavioral context in favor of brevity.

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 bulk mutation tool affecting potentially many users, with no annotations and no output schema, the description is incomplete. It fails to explain the exact semantics of the assignment update, how invalid inputs are handled, whether this is a replace-all operation, or what response the caller should expect. The ambiguity is significant given the large sibling set of user and squad management tools.

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 already documents both parameters with 100% coverage. The description adds the context of 'internal squad assignments' and 'selected users', which maps to the activeInternalSquads and userIds fields, but it does not deepen the meaning beyond what the schema already provides.

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 specific action ('Bulk update'), a resource ('internal squad assignments'), and a target ('selected users'), which is clear enough to identify the tool's main job. However, it does not explicitly distinguish itself from squads_add_users or squads_remove_users, nor does it say whether this replaces the existing squad set or just adds to it.

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?

There is no guidance on when to use this tool over siblings like squads_add_users, squads_remove_users, users_bulk_update, or external_squads_*. The description implies a bulk operation but gives no context for choosing it among the many related user/squad mutation tools.

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