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

Annotations already declare readOnlyHint, openWorldHint and idempotentHint, so safety context is covered. The description adds genuinely useful non-schema facts: it is free, costs no payment, requires one call, and every field is optional. It does not state where feedback goes or whether it is anonymous, so the added context is helpful but partial.

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?

Front-loaded with the salient 'FREE.' then two tight clauses covering scenarios and constraints. Efficient overall; the scenario enumeration is a little long but each part earns its place.

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 7-parameter, zero-required feedback tool with no output schema, the description covers cost, optionality and invocation count but omits what happens to the feedback and any anonymity/persistence detail. Adequate but not fully complete for a mutation-adjacent submission tool.

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 high (86%) and the schema already documents 5 of 7 fields with descriptions and enums, so the baseline is 3. The description loosely maps scenarios onto fields ('why you did not buy' -> kind/reason, 'what data...you needed' -> wanted, 'whether a paid answer was right' -> rating), adding some meaning but no field-level detail beyond the schema.

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?

States a specific verb plus resource ('Tell Maxwell...') and enumerates the concrete cases it covers: why you didn't buy, what data/category/product was missing, or whether a paid answer was right. An agent can distinguish it from transactional siblings like call_product or get_price_quote. It is clear but slightly rambling rather than crisp verb+resource phrasing.

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 names the triggering scenarios ('why you did not buy', 'what...you needed that is not here', 'whether a paid answer was right'), which tells the agent when to reach for this tool. It does not explicitly name an alternative or exclusion, so it is context-rich but not routing-complete.

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