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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=true, and idempotentHint=false, so the agent knows this is a non-mutating read. The description adds useful context about how the answers are consumed by auto-apply, but says nothing about ordering, volume, or whether answers are per-user or per-employer scoped.

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: the first identifies what is returned and gives illustrative examples, the second supplies the reason it matters. Front-loaded and appropriately sized for a parameterless list tool.

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-parameter, read-only list tool whose safety profile is fully covered by annotations, the description supplies enough to call it correctly. The only minor gap is the absence of any hint at the return shape, which matters slightly since there is no output schema.

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 tool takes zero parameters, so the baseline of 4 applies; there is no parameter semantics for the description to explain. Schema description coverage is 100% and the schema is an empty object, so nothing is left undocumented.

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?

Specific verb plus resource: lists the person's saved answers to open-ended screening questions, with two concrete example questions that make the content unambiguous. It does not differentiate itself from the sibling screening_answers_get, so an agent could hesitate between the two, but the core purpose is clear.

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 second sentence implies why the list matters ('automatic applications reuse them on every form that asks the same question'), which hints at review-before-auto-apply usage. However, it never states when to call this versus screening_answers_get, answer_bank_save, or answer_bank_delete, and gives no prerequisites or exclusions.

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