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

With no annotations, the description carries the full load, and it does disclose real behavior: the ordering guarantee and the role-scoped result set. It stays silent on pagination or result limits, auth requirements, and empty results, which keeps it short of a 5 for an unannotated read tool.

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 sentences, zero filler. The resource and ordering come first, the role split follows, then the handoff to get_thread. 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?

For a one-parameter read tool this is close, but two gaps remain: the identity of 'id' (RFQ vs thread) is unstated, and with no output schema the description says nothing about what a thread entry contains. Either addition would make it complete.

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?

The schema documents a single uuid, 'id', with 0% description coverage, and the description never explicitly says whether that id is the RFQ id or the thread id. The phrase 'threads on an RFQ' implies the RFQ id, but an agent could plausibly pass a thread id and get an error. The implication is the only extra meaning added.

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?

It names the resource precisely ('negotiation threads on an RFQ') and states the result ordering ('newest activity first'), plus the role-dependent scope: a maker sees every quote on their own RFQ, a taker sees their own thread. It also distinguishes itself from get_thread, which retrieves a single thread. The only shortfall is that the verb 'list' is implicit rather than stated.

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?

It gives an explicit use case ('this is how a taker finds the quotes it received') and an explicit next step ('open one with get_thread'). It doesn't rule anything out against alternatives like get_rfq or list_my_rfqs, but the make/take framing effectively routes the agent to the right invocation.

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