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

With no annotations, the description carries the full behavioral burden, yet it only says the listing is "taken down." It doesn't disclose whether the action is reversible, what happens to the listing's data or state afterward, whether confirmation or specific permissions are required, or what the response contains — all material for a destructive mutation.

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?

A single short, front-loaded sentence with no filler or repetition. It is efficient, though its brevity edges toward under-specification rather than true conciseness.

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?

For a destructive mutation with zero annotations, no output schema, and an undocumented required parameter, the description is far too thin. An agent cannot determine side effects, recoverability, or success/failure signalling from what is provided.

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?

Schema coverage is 50%: the session token is documented in the schema, but the required `id` parameter (length 10-60) has no description anywhere, and the description adds no clarification such as whose listing id is expected. With no enum or format hints, the agent gets no help identifying the id's origin or constraints.

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?

States a specific action ("takes down") on a specific resource ("listing of this account"), which clearly separates it from read/creation siblings like listing_draft, listing_status, and listings_published. It stops short of naming what makes withdrawal distinct (e.g., irreversible removal vs. unpublishing), so it lacks explicit sibling differentiation.

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?

There is no when-to-use guidance, no prerequisites, and no mention of the related tools (listing_confirm_usdc, listing_status, listings_published) an agent might weigh instead. The agent must infer that withdrawal is the terminal step in the listing lifecycle.

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