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

Annotations already cover readOnly/idempotent/non-destructive, so the bar is lower, and the description still adds value by disclosing the auth requirement (token from create_rfq) and the scope of returned data (matches plus quotes 'received so far'). It does not discuss the token's lifetime or secrecy, so it is not fully complete.

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 short sentences, front-loaded with purpose followed by the prerequisite inputs. No redundant restatement of the name or annotations; every clause 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?

With no output schema, the description needs to convey what comes back, and it does so at a high level (matches and quotes received so far). For a simple two-parameter read tool whose safety profile is covered by annotations, this is nearly sufficient; only token handling details are missing.

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 0% with two parameters, so the description carries the burden and does explain both: rfq_id and the token, including where the token comes from (create_rfq). It does not explain rfq_id's format or the token's validity constraints, leaving a small gap.

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 (Read) and resource scope (matches and quotes for an RFQ), which is more informative than the bare name. It is distinguishable from siblings like get_rfq_requirements or get_rfq_thread by naming matches and quotes, though it never explicitly contrasts with them.

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?

"For an RFQ you created" implies the usage context and preconditions, but there is no explicit when-to-use guidance or naming of alternatives such as get_rfq_thread or get_rfq_requirements. Usage is inferable rather than stated.

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