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

The description adds real context beyond the annotations by disclosing the access-token requirement and the precondition of a verified link, and 're-checks' is consistent with idempotentHint=true and readOnlyHint=false. However, it does not say what happens when the check fails, whether the call mutates listing state, or what the caller receives, which matters for a non-read-only 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?

Two short sentences with no filler, and the core action is front-loaded. The trailing auth note is slightly tacked-on but still earns its place.

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?

With one fully documented parameter and no output schema, the essential calling information is present, but for a mutating gate operation the description leaves the outcome (what a caller learns on success vs. rejection) unstated. Adequate but with a clear gap.

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 100% and the single productId parameter is fully documented, including where to obtain it (submit_product or list_my_products). The description adds nothing about the parameter, so the baseline 3 applies.

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 uses a specific verb phrase ('re-checks whether a listing with a verified link can go live'), which turns the generic name 'publish' into something an agent can act on. It does not name or contrast with siblings such as submit_product or verify_backlink, so a reader must infer the boundary themselves.

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 clause 'e.g. after the founder confirmed their email' hints at the trigger condition, but it is phrased as an example rather than a rule, and it is not stated whether this is required after verify_backlink or whether submit_product already covers it. Usage is implied rather than prescribed, and no alternatives are named.

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