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

With no annotations, the description carries the full burden and does add one real behavioral trait: offers expire. However, it says nothing about the signing/authentication requirement implied by the wallet, nonce, and signature parameters, what happens after expiry, or any rate limits, leaving significant gaps for a mutation 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 tight sentences front-load the core action and append the expiry constraint with zero filler. It is arguably too sparse, but nothing in the text is wasted.

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 an 8-parameter, 5-required mutation tool with no annotations, no output schema, and 0% schema description coverage, the description covers only a few concepts and omits the signing flow and return behavior. An agent could not invoke this confidently from the definition alone.

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% across 8 parameters, so the description must compensate. It adds meaning for price ('base units'), token (currency), and ETA (eta_hours), but leaves the four required signing parameters (id, wallet, nonce, signature) and note completely unexplained, so most of the contract remains opaque.

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 states a specific verb (offers) and the resources being offered (price, token, ETA) on a negotiating task, which is clearer than a bare name. It implicitly separates this from counter_offer by establishing the seller's initial offering role, but it never names or contrasts the sibling tools explicitly.

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 explicit guidance on when to use this versus accept_offer, counter_offer, or request_quote, nor any stated preconditions for making an offer. 'On a negotiating task' hints at the context but stops well short of routing guidance.

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