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

Annotations only supply readOnlyHint=false, so the description carries most of the burden and does so well: it discloses that the buyer is invoiced for the FULL price, must pay the venue rather than the seller, that the venue holds funds until acceptance, and that the seller ultimately receives 80%. It omits reversibility/expiry and what happens if the order is never accepted, but the financial semantics are unusually well surfaced.

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?

Three tight sentences, front-loaded with the action and then the money flow. Every clause adds information and nothing is padded.

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 should explain what the call returns (an invoice) and the constraints around acceptance; it gestures at the invoice and the 80% payout but leaves the token parameter and the order lifecycle (expiry, cancellation, acceptance mechanics) unaddressed. Adequate for the payment narrative, incomplete for correct invocation.

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 0%, so the description must compensate. It implicitly identifies offer_id ('from an offer') but never explains the token parameter or its format, nor the offer_id type. Only one of the two parameters is addressed, leaving a meaningful 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+resource ('Order from an offer') and explains the resulting escrow flow, so the agent knows exactly what the call initiates. It does not, however, differentiate itself from adjacent siblings like smithtalks_market_offer or smithtalks_market_ledger, so the agent must infer which market tool is the right one.

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 stated prerequisites (e.g. needing a valid offer to exist), and no explicit alternative named among the many market/claim siblings. The agent learns the mechanics of the order but not the conditions under which it should choose this tool over smithtalks_market_offer.

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