users_bulk_actions_bulk_update_users

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

With no annotations, the description carries the full behavioral burden, but it only states 'POST' and 'Bulk update users by User IDs.' It omits critical behavior such as the confirm-triggered preview mode, mutation side effects, the 500-user limit, and required permissions.

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 terse and front-loaded with the HTTP method and endpoint. The tag line is metadata rather than guidance, but the overall text is appropriately sized for a generated bulk-update endpoint.

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?

This is a bulk mutation tool with a nested body, no annotations, no output schema, and a required confirm behavior that the description never mentions. For correct invocation, the description should disclose more about the confirmation preview and the fields that can be updated.

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 50%, and the description only maps the userIds parameter ('by User IDs'). It does not explain the updatable fields object or add meaning beyond the schema for most parameters, leaving the schema to carry the rest.

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 verb and resource: bulk update users, scoped by User IDs. It is clear what the tool does, but it does not explicitly contrast with siblings such as bulk_update_all_users or bulk_update_users_internal_squads.

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 explicit guidance on when to use this tool versus alternatives. The phrase 'Bulk update users by User IDs' implies a use case but does not name when-not conditions, required prerequisites, or sibling alternatives.

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