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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered and the description correctly does not contradict it. What the description contributes beyond annotations is the return content — the three contact channels — which matters because no output schema exists. It stops short of saying whether the response is static or where the form/email lead, but the added value is real.

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?

A single sentence with the resource named first and the return contents listed as a compact triad. Every clause carries information and nothing is repeated from the title or annotations.

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 zero-argument, read-only, closed-world lookup tool with no output schema, the agent needs only to know what it returns and how it relates to the sibling that actually submits the request. The description supplies both, so nothing required for a correct call is missing.

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?

The input schema has zero parameters and the schema description coverage is 100%, so there is nothing for the description to clarify on the parameter side. Baseline for a zero-parameter tool is 4; no parameter meaning is missing.

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 gives a specific verb ('Return') and a specific resource ('the ways a person can contact Excession Labs'), then enumerates the exact contents: request form, email, and a tool reference. It even names the sibling tool request_security_test as one of the returned contact routes, so an agent can distinguish this discovery tool from the actual request-submission tool.

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?

There is an implied usage hint: the phrase 'the request_security_test tool for agents' signals that agents should follow through to that tool rather than a human channel like the form or email. However, there is no explicit statement of when to call this tool instead of a sibling such as get_page or search_site, and no prerequisites or exclusions are given.

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