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

Beyond the annotations (which only say it is not read-only, not destructive, not idempotent), the description discloses the human-review workflow and that fulfillment arrives by email rather than in the tool response – exactly the kind of context an agent needs to avoid expecting an immediate key. It does not say whether repeated submissions create duplicates or what the immediate caller-visible result is.

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, front-loaded with the action and followed by the crucial fulfillment caveat; no filler.

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 no output schema, the description carries the burden of explaining what happens after the call, and it does so (human review, email reply, no automatic issuance). Minor gap: it does not describe what the tool returns immediately (confirmation, ticket id) or expected turnaround.

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% and all four required fields (name, company, email, purpose) are documented in the schema itself. The description adds no field-level meaning, so the baseline of 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?

"Ask for a verified-buyer key" is a concrete verb plus resource, and the name reinforces it. It is clearly the only submission/request tool among the read-oriented siblings, though the description never states that distinction explicitly.

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 description implies the situation (you want a verified-buyer key) and warns that it is not self-service, but gives no explicit when-to-use/when-not guidance or prerequisites such as whether an existing key or account is required.

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