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

With no annotations, the description carries the full burden and does good work: it discloses that no account is required, that models are hidden from raters, and — critically — that anyone holding the link can read the answers and inputs, prompting a consent check. It omits link lifecycle details (expiry, revocation, whether it is reusable) and does not say the call returns the URL, which matters since there is no output schema.

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?

Three short sentences, front-loaded with the payload's nature, then the audience, then the privacy caveat. Some value is lost because the opening is a noun phrase rather than an action, so the first read doesn't make clear that this is a call the agent performs.

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 single-parameter tool this covers purpose, audience, and the main security implication well. It falls short on the return value (the link itself, unstated and no output schema) and link lifetime/revocation behavior, both of which an agent needs before promising a shareable artifact.

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 0% and the single required parameter test_id is never named or explained in the description; the agent must infer that the exposed answers and inputs belong to the referenced test. The prose implies the link is scoped to one test but adds no format or validity guidance beyond the field name.

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 concrete deliverable — a shareable rating link for a test's answers — and distinguishes its mode from siblings like score_answers by noting it is phone-based, accountless, and model-blind. It never states an explicit action verb ("generate/create"), so the agent must infer that calling it produces the link, but the resource is unambiguous.

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?

"Send it to whoever knows what good looks like" gives an implied when-to-use, and "ask before sharing" adds a sharing precondition. There is no explicit routing versus alternatives such as score_answers or list_judges, and no statement of when not to use it.

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