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

Annotations already declare mutation, open-world behavior, and idempotency. The description adds useful context beyond them: it checks the live homepage externally, performs a conditional publish only if the link exists, and requires an access token.

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 front-loaded and efficient: it states what is checked, the conditional side effect, the timing, and the auth requirement in three tight clauses with no wasted text.

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 one-parameter tool with annotations covering mutation, open-world access, and idempotency, the description is largely complete. It does not explain the result when the link is absent or describe error/response behavior, but no output schema exists and the core calling context is covered.

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 100%, so the single `productId` parameter is already documented in the schema. The description does not add any parameter-level meaning beyond what the schema provides, which is the expected baseline for high-coverage schemas.

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 a specific compound action: checking the live homepage for the Launchator link and conditionally publishing the listing. This is clearer than a generic verify tool, but it does not explicitly distinguish itself from the sibling `publish` tool or explain when the verification path should be preferred.

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?

It gives a clear calling condition: after the site with the link is deployed. It also states the conditional behavior if the link is found. However, it does not explicitly contrast this with the sibling `publish` tool or state what to do when verification is unnecessary.

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