C2.6/5.0
Behavior2/5

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

With no annotations, the description must carry the burden of behavioral disclosure, but it only says 'Resets the User Password.' It does not explain whether currentPassword is required for verification, whether admin privileges are needed, whether existing sessions are invalidated, or how this differs from a token-based reset flow.

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

Conciseness3/5

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

The description is minimal and contains no filler, but it is under-specified rather than efficiently complete. A single short sentence can be concise, yet here it omits essential context that would make the tool safely usable.

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

Completeness2/5

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

For a password mutation with no annotations and no output schema, the description leaves critical details unresolved: target user identity, permission requirements, and the role of currentPassword. The large sibling list makes this ambiguity more harmful because multiple nearby tools could be selected by mistake.

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

Parameters2/5

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

Schema description coverage is 0%, yet the description only implicitly relates to newPassword. It adds no meaning for currentPassword or accept-language, and does not clarify whether currentPassword is required or what accept-language affects.

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

Purpose4/5

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

The description clearly states the core action ('Resets') and resource ('the User Password'), so an agent can tell this is a password mutation tool. However, it does not specify whose password is affected or differentiate it from similarly named siblings like create_users_reset_password or update_users_by_item.

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

Usage Guidelines2/5

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

No guidance is provided about when to use this tool versus alternatives such as create_users_reset_password or update_users_by_item. There are no conditions, prerequisites, or exclusions, leaving the choice to inference.

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