Get a user

get_user
Read-onlyIdempotent

Retrieve a Wiki.js user's full account details by numeric ID, including group memberships and two-factor authentication status.

Instructions

Full detail for one account, including its group memberships and whether two-factor authentication is active. No credential of any kind is returned — Wiki.js does not expose one.

TDQS

A4.1/5.0
Behavior4/5

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

Annotations already cover read-only, idempotent, non-destructive behavior. The description adds meaningful behavioral context by stating that credential data is never returned and by naming specific included fields (group memberships, TFA status). This goes beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two concise sentences with no filler. The core purpose is front-loaded, followed by key detail and a relevant negative guarantee. Every part earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple single-parameter read tool with a full input schema, an output schema, and comprehensive annotations, the description is complete. It explains what is returned, what is not returned, and identifies the required ID.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for the single user_id parameter, which is already documented as a numeric Wiki.js id. The description references 'one account' but does not add parameter format or usage details beyond what the schema provides, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb and resource ('Full detail for one account') and clearly identifies the object returned, including group memberships and TFA status. This distinguishes it from list_users or search_users, which would return multiple or filtered users.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when a caller needs complete detail for a single specific user, but it does not explicitly contrast with sibling tools like list_users or search_users, nor state when not to use it. The guidance is adequate but implicit.

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