create_lists_by_id_report

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

Annotations already indicate idempotent, non-destructive, mutating behavior. The description adds no behavioral detail beyond the fact that it reports a list; it does not mention side effects, permissions, or response expectations, so it contributes little beyond annotations.

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 very short and front-loaded with the core purpose. It includes the endpoint and argument explanations without fluff, though it may be too terse for critical information.

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 having an output schema and annotations, the description is incomplete for an agent deciding when to invoke this tool. It lacks any context about what reporting entails, how it differs from similar report tools, or any usage conditions, leaving the agent to infer.

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 description clarifies that 'id' is an id/slug and that 'body' is a payload to be built after consulting the GET or /schema endpoint. Since the body schema is an open object with no defined fields, this pointer is essential and adds value, though it does not enumerate any actual fields.

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 states the verb 'Report' and the resource 'a list', with the endpoint POST /lists/{id}/report making the target explicit. It is not a tautology but is extremely brief and does not differentiate from the many sibling report tools beyond the resource type.

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 provides no guidance on when to use this tool versus alternatives like create_users_by_id_lists_by_list_id_report. The only instruction is to read the GET or /schema endpoint to construct the body, which addresses the body parameter but not tool selection or context.

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