Bulk Update Project Details For Company Users On Projects

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

Annotations already indicate the tool is not read-only and not destructive. The description adds that only supplied fields are changed (partial update) and that users must be pre-assigned. This provides useful context beyond annotations, but does not disclose potential side effects, rate limits, or authorization scope beyond 'company users'.

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 reasonably concise, clearly stating the purpose, preconditions, and key parameters. It includes API version and endpoint, which adds useful context without excessive verbosity. The information is front-loaded with the main action.

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?

The description covers the main purpose, mandatory preconditions, and that it updates existing records. However, it lacks details on error handling, response format (no output schema), or confirmation of success beyond 'returns the modified object'. Given the tool's complexity (bulk update with arrays), additional guidance on common errors or validation rules would enhance completeness.

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?

Input schema coverage is 100%, with both parameters described. The description reiterates the required parameters and adds context about the users array structure (permission template id, project_role_ids, project id) and a maximum of 1000 items per request, which aligns with the schema. No significant additional meaning is provided beyond 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 the tool updates project details for company users in bulk, specifying it modifies existing directory records and only changes supplied fields. The tool name is descriptive, and the description differentiates from removal operations like bulk_remove_project_details_for_company_users_on_projects, though it does not explicitly contrast with similar update tools.

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?

The description notes a key precondition (users must be assigned to the project before updating) and states this is for updating existing records. However, it does not provide guidance on when to use this tool versus alternatives (e.g., individual update endpoints or bulk_remove), nor does it specify when not to use it.

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