mongo-changePassword

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

Description adds no behavioral traits beyond annotations (idempotentHint=true, openWorldHint=true). It does not mention side effects, required permissions, or whether the change is immediate.

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 extremely short but lacks substance; it is under-specified rather than concise, providing no usable information for an agent.

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 no output schema, basic annotations, and 0% parameter coverage, the description is completely inadequate. An agent cannot determine the tool's purpose, parameters, or behavior.

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?

With 0% schema description coverage, the description entirely fails to explain the two required parameters (mongoId, password). No meaning is added beyond the minimal schema validation pattern.

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?

Description is 'POST /mongo.changePassword', which only restates the endpoint path and provides no verb-resource clarity. It fails to explain that the tool changes a MongoDB password.

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?

No guidance on when to use this tool versus sibling tools like mongo-changeStatus or other database change-password tools. No context about prerequisites or alternatives.

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