Bulk Update Users from CSV

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

While annotations already declare destructiveHint=true and readOnlyHint=false, the description adds critical context by stating 'Defaults to dry_run=true', which tempers the destructive signal. This is valuable behavioral disclosure beyond the annotations, though it does not detail what happens when dry_run is disabled or mention permissions/rollback.

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 concise and well-structured, with a short opening sentence, a succinct list of columns, and a relevant use case. Every sentence adds value, and there is no redundant filler.

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's complexity (4 params, no output schema) and the presence of annotations, the description is largely complete. It covers the core action, CSV requirements, dry-run default, and a use case. It omits details on stop_on_error and response_format, but those are inferable from their names. Minor gaps prevent a perfect score.

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 50%, with only csv_path and response_format described. The description compensates by explaining the required 'id' column, the optional columns, and the roles format. It also clarifies the dry_run default, which is explicitly present in the schema but reinforced here, adding helpful context.

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 many users from a CSV, specifying the resource (users) and the method (bulk update from CSV). This distinguishes it from sibling tools like wp_update_user (single user update) and wp_bulk_update_posts (bulk post update).

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 provides a concrete use case ('demote stale admins identified in the website audit'), making the intended context clear. However, it does not explicitly mention when not to use this tool or compare it to alternatives like wp_update_user for single-user updates.

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