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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=true, so the safety profile is carried elsewhere; the description does not contradict them. It does add one genuinely useful behavioral fact -- the independent private link survives the unpublish -- but omits what else is torn down (listings, deployments, strategy visibility) for a destructive operation.

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?

Two short sentences, zero filler, with the scope constraint front-loaded. It is efficient, though for a destructive tool with an ambiguous sibling, the brevity edges into under-specification rather than pure tightness.

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?

Context signals show a destructive mutation with 0% schema coverage, no output schema, and a confusingly similar sibling. The description covers only scope and one side effect -- it is not complete enough for an agent to choose this tool confidently or predict the aftermath of the call.

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 description coverage is 0%, so the description must compensate, and it only partially does: "exactly one" and "owner" hint that publicationId selects a single owned publication and that ownership is required. It gives no format, no mention that the id is a UUID, and no error behavior for a non-owned or already-removed id.

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 verb and resource ("Unpublishes exactly one owner publication") and adds the singular scope constraint. However, it never says WHAT is being unpublished (an account or strategy, which only the title reveals), and there is a near-synonymous sibling, unpublish_from_marketplace, that the description does nothing to distinguish itself from.

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 indication of when to use this versus unpublish_from_marketplace, save_marketplace_publication, or publish_to_marketplace. No prerequisites such as needing to be the publication owner, and no warning that the action is destructive and should be used deliberately.

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