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

Annotations already declare readOnlyHint=false, idempotentHint=false and destructiveHint=false, so safety basics are covered. However, the description adds no behavioral context of its own — it never says that accept/counter are binding commitments to the buyer, whether a decision can be changed, or what happens on repeated calls despite the non-idempotent flag.

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?

It is a single front-loaded clause with no waste, but it is so terse that it borders on under-specification; the parenthetical qualifier is the only extra information offered.

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 state-changing seller action with no output schema, the description omits the outcome of each decision (e.g. that accepting creates an order or locks in terms) and any error or precondition context. Annotations cover only the generic safety profile, leaving the workflow gaps unaddressed.

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 description coverage is 100%, including the action enum and the counter_price dependency, so the schema carries the parameter burden. The description adds no parameter detail, making the baseline 3 appropriate.

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 names a specific verb+resource ("Respond to a buyer's quote request") and the "(seller tool)" qualifier separates it from buyer-side siblings like request_quote and get_quote_requests. It is clear what the tool acts on, though it doesn't explicitly name which sibling to prefer.

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 alternatives such as get_quote_status or get_quote_requests. The agent must infer the workflow entirely from the name.

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