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

With no annotations, the description must carry the behavioral disclosure burden. It does usefully state that the tool is free and does not charge or hold funds, which is important given the financial-looking parameters. However, it does not disclose other relevant behaviors such as whether the intent is publicly visible, whether authentication is required, or whether any follow-up action is triggered.

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?

The description is very short and front-loaded with the core action. The 'does not charge or hold funds' clarification is valuable, though 'Free' and 'does not charge' are somewhat redundant. It is appropriately concise but perhaps too terse for the tool's complexity.

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?

Given 8 parameters, 5 required, no parameter descriptions, no output schema, and no annotations, this description is insufficient for an agent to confidently invoke the tool correctly. The agent is left to guess formats for fields like deadline, max_price_usd, and ship_to_country, and cannot tell how this tool relates to sibling tools.

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% and the description provides no meaning for any of the 8 parameters, including required fields like spec, quantity, max_price_usd, ship_to_country, and deadline. The description does nothing to compensate for the lack of schema descriptions.

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 clearly states the action ('Record') and the resource ('a buy intent'), which is specific and understandable. It also implies a buyer-side action that contrasts with 'post_offer', though it does not explicitly distinguish itself from 'cover_intent' or other siblings.

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?

The description gives no guidance on when to use this tool versus alternatives like 'post_offer', 'cover_intent', or 'open_checkout'. There is no mention of prerequisites, typical scenarios, or exclusions.

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