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

With no annotations, the description carries the full burden. It does real work by enumerating the four status states and what each means (e.g. 'ready' includes total and line pricing), which is genuine behavioral context. However, it omits error behavior for unknown/expired ids, auth requirements, and whether the call is a safe read.

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 tight sentences with the core purpose front-loaded and the status enumeration appended. No filler, though the status list makes sentence two dense.

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 output schema, the description correctly compensates by spelling out the returned status values and what accompanies 'ready'. Complete enough for a one-parameter read tool, though error and missing-quote cases are 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% and the single rfq_id is already documented as 'the rfq_id returned by submit_rfq', so the baseline of 3 applies. The description adds nothing about the parameter itself.

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 and resource ('Returns the current state of a quote'), which is clear and distinct from the sibling resources (order, supplier capabilities, rfq submission). It does not, however, explicitly name or contrast itself with any sibling, so it falls short of a 5.

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 only implied: describing the status lifecycle suggests polling a quote after submit_rfq and before accept_quote, but the description never says when to call it or when not to. No prerequisites, no alternative tools named.

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