Behavior2/5

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

With no annotations, the description carries the full burden of behavioral disclosure. It does not say this is an irreversible mutation, whether the current session survives, what authentication is required, or what the result looks like.

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?

A single, front-loaded sentence with no waste, but it is under-specified for a seven-parameter mutation tool. Conciseness here comes at the cost of necessary information.

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?

A mutation tool with no annotations, no output schema, seven parameters, and only 57% schema coverage needs more than five words. The description lacks authentication, confirmation, and irreversibility context.

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 57%; the required password fields (current_password, password, password_confirmation) have no schema descriptions and the description does not compensate. The agent is left to infer that password_confirmation must match.

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?

States a specific verb ('Change') and resource ('account password'), so the agent knows this is a password-mutation tool. It is close to the title but adds the account scope; there is no sibling differentiation, though sibling account_update_email covers a different field.

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 on when to use this versus account_apikey_create or account_update_email, and no prerequisites. The description does not mention that the current password is required or that the new password must be confirmed.

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