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

The description goes well beyond the annotations by disclosing that accepting immediately creates a confirmed order, does not charge any payment method, and that the buyer later pays through the normal flow. It also requires an Authorization header. These behavioral details meaningfully inform the agent about side effects and prerequisites.

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 dense but every sentence carries essential information: core purpose, role/action rules, side effects, and authentication. It is front-loaded with the main purpose and then details conditions without redundancy.

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?

The tool has role-dependent state transitions and side effects, and the description covers all critical aspects: valid actions per role, required offer state, counter_price condition, the confirmed-order consequence, payment behavior, and auth requirements. Given the output schema exists, return-value documentation is not the description's responsibility.

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 100%, so the baseline is 3. The description adds role-based meaning by mapping actions to seller versus buyer, and explicitly notes that counter requires counter_price. This supplements the schema's field-level descriptions with usage context.

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 tool responds to a pending Make an Offer / bargaining offer, with specific actions (accept, reject, counter, accept_counter). It differentiates the resource (offers) from sibling tools like orders.place or orders.reject by focusing on offer response semantics.

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 strong context on when to use it: the offer must be pending or countered depending on caller role, and the valid actions are role-dependent. It does not explicitly name alternatives or say when not to use it, but the role/state conditions are clear enough to guide correct invocation.

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