users_bulk_actions_bulk_update_users_internal_squads

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses essentially nothing: no permissions/scope requirements, no reversibility, no statement of what happens to existing squad assignments, and no note of bulk limits (max 500 IDs lives only in the schema). The only behavioral signal is the literal 'POST' verb, which is already implied by the tool name.

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 it spends lines on raw HTTP route and an internal 'Tags: Users Bulk Actions Controller' label that carries no selection value for an agent. The substantive sentence is front-loadable but not elaborated, so the length is small yet poorly invested.

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 with nested body objects, no output schema, no annotations, and a mandatory 'confirm' gating mechanism, the description is inadequate. It does not explain the preview-vs-execute confirm flow, the 1-500 userId limit, or any result/impact of the operation, leaving the agent to infer the write semantics entirely from the route string.

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 only 50%, and the documented half (a Russian-language 'confirm' flag on the top-level object) is not echoed or clarified by the description. The description's lone parameter hint, 'by User IDs', restates what the schema already names, and it says nothing about 'activeInternalSquads' semantics (replace vs. add, empty-array behavior). The description fails to compensate for the coverage gap.

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 verb and resource ('Bulk update users internal squads by User IDs'), so the general intent is legible. However, 'update internal squads' is ambiguous about whether the supplied squad list replaces or merges with existing memberships, and there is no differentiation from the very similar sibling 'internal_squad_add_many_users_to_internal_squad'. This ambiguity around the core behavior keeps it at vague-but-present rather than clear.

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 when-to-use guidance, no mention of prerequisites, and no reference to alternatives such as 'internal_squad_add_users_to_internal_squad' or 'users_bulk_actions_bulk_update_all_users'. The agent receives the operation name and nothing about when it should be chosen over its siblings.

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