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

Annotations already declare destructiveHint=true and idempotentHint=false, so the agent knows this is a non-idempotent destructive write. The description adds that confirmed=true is required and that the ChannelOAuthId header is resolved internally, which is useful, but it does not say what gets created/changed, what scope of listings is affected, or whether the operation can be reversed. "Returns the result or applies the effect" is empty filler.

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 text is padded with boilerplate that earns nothing: "Dedicated HGRApi tool... it is not a generic endpoint caller," "HGRApi functional documentation," and "Search terms: listing autolist." The useful facts (bulk publication, confirmed gate, channel header) are buried among restatements of the endpoint name.

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?

An output schema and annotations exist, so the description need not explain return values or safety flags. However, for a destructive, non-idempotent bulk operation with an opaque request body, an agent still lacks the information needed to know what the call will do to the account's listings.

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 nominally 100%, but the body is an opaque object with no declared properties, so the schema provides almost nothing about payload shape. The description partially compensates by naming one field (WeListForYou: bool) and noting the request payload goes in the body verbatim, but a single named field out of an unspecified payload is thin.

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 names a specific verb and resource ("POST auto list operation in bulk publication and publication tracking") but the phrasing largely restates the endpoint name and title. It never explains what an "auto list" actually does, and it does not distinguish itself from near-identical siblings such as hgr_post_listing_saveautolist, hgr_post_listing_savebulkpublish, or hgr_post_listing_getbulkhistory.

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?

"Use when: Use it when a client needs to run the auto list operation" is circular — it gives no condition that would let an agent choose this over the several sibling tools that also touch bulk listing publication. The only concrete guidance is the confirmed=true gate, which is already documented in the schema.

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