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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the answer is recorded but not published and that a name is optional, which are important privacy and anonymity traits. It still omits details about authentication, rate limits, or confirmation behavior.

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 two short sentences with no wasted wording. The purpose and the key behavioral note about recording versus publishing are front-loaded and easy to scan.

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 simple two-parameter feedback tool with full schema coverage and no output schema, the description covers the essential purpose, optional anonymity, and storage behavior. It is nearly complete, though it could mention what confirmation the caller receives.

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 100%, so the baseline is 3. The description adds meaning by framing 'why' as a one-sentence explanation and clarifying that the name is optional either way, reinforcing the anonymity context beyond the schema's 'your agent 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 clearly indicates that the tool collects a reason for not choosing something, with a specific prompt: 'Not for you? Tell us in one sentence why.' It does not explicitly differentiate itself from siblings such as decline or answer_challenge, so it is clear but lacks sibling routing.

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?

Usage is implied by the phrase 'Not for you? Tell us...', which suggests submitting feedback after a negative outcome. However, it does not state when not to use it, what alternatives exist, or any prerequisites, leaving the agent to infer the context.

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