passgage_update_user_rate

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

No annotations are provided, and the description discloses no behavioral traits beyond the action. It does not mention required permissions, whether the update is partial or full replacement, or what the response will be—significant gaps for a mutation tool.

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 a single sentence with no wasted words, clearly front-loading the action and resource. It earns its place and is appropriately concise.

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?

Despite being a simple CRUD operation, the description is insufficient for an agent to invoke it correctly. It lacks details about the data structure, permissions, return values, or constraints. The schema's 'data' object is undefined, and with no annotations or output schema, the tool is significantly under-specified.

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?

The input schema has descriptions for both parameters, giving 100% coverage, so the baseline is 3. However, the description adds no extra meaning to the parameters. The nested 'data' object is open-ended (additionalProperties: true) and its schema description is circular, leaving the updatable fields vague, and the description does not clarify this.

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 action ('Update') and resource ('user_rate'), and it is the only tool for updating user_rates among the siblings. However, it is terse and largely restates the tool name, without adding any distinguishing scope.

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 offers no guidance on when to use this tool versus alternatives like passgage_create_user_rate or passgage_delete_user_rate. It provides no context about prerequisites, typical use cases, or exclusions.

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