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

No annotations are supplied, so the description carries the full behavioral burden and does not meet it: nothing about whether the call is read-only, what permissions it needs, what the response contains, or how deterministic it is. The single concrete claim, that it 'includes the complete prompt, usage guide, and edge-case handling,' describes packaged content rather than runtime 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?

Three short sentences, but the leading sentence is a slogan and the remainder is promotional filler ('professional results in minutes'), so nothing is front-loaded that helps selection. It is brief without being informative.

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 annotations and no output schema, the description should explain what a 'diag' call returns and how it differs from the sibling refund tools; it does none of that. An agent would have to guess both the invocation purpose and the expected output.

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?

There is only one optional parameter and schema description coverage is 100%, so the schema already explains that 'query' scopes the analysis. The description adds no further meaning to it, which lands at the baseline of 3 for a fully documented single parameter.

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 text mostly restates the name: 'This refund diag tool prompt pack' plus generic marketing about 'turn expertise into output' and 'produce professional results in minutes.' It never states what a refund diagnosis actually produces (a diagnosis report? a scorecard? an action list?), so an agent cannot distinguish it from the many sibling refund tools such as refund-analyze-tool, refund-board-tool, or refund-formula-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 no when-to-use guidance, no prerequisites, and no mention of any alternative. The only contextual hint is the audience ('restaurant and brand teams'), which does not tell an agent when this diagnostic tool should be chosen over the analyze/board/formula/tpl siblings.

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