place_orders_batch

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

With no annotations present, the description carries the burden of disclosure. It explicitly states 'Requires API credentials' and 'This submits REAL orders to the matching engine,' which is strong mutation/side-effect warning. It does not mention batch atomicity, partial failures, or return behavior, but the most critical risk is addressed.

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 brief and front-loaded, with three sentences that each carry meaningful info: what it does, how the order shape is derived, and the real-order behavior. The parenthetical field list is dense but aids completeness without bloating the text.

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 rich nested schema covers the parameter semantics thoroughly. The description adds the missing non-schema information: credential requirements and real trading side effects. It does not explain batch-level behavior such as atomicity or failure handling, but overall it gives an agent enough context to invoke the tool correctly.

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% and the nested order properties are extensively documented. The description adds convenience by referencing the `place_order` shape, but it does not add substantive new semantics beyond what the schema already provides, so the baseline 3 applies.

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 uses a specific verb ('Submit'), names the resource ('multiple orders in one request'), and clearly distinguishes the tool from the sibling `place_order` by emphasizing batch capability. It also summarizes the relevant order fields, leaving no ambiguity about what the tool does.

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 clearly implies this is the batched counterpart to `place_order`, giving context that it should be used when submitting multiple orders together. It does not explicitly state when-not to use it or name alternatives, but the intended usage is clear from the wording.

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