create_orders

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

With no annotations, the description carries the full burden but does disclose two important traits: credential requirement and that real orders hit the matching engine. It omits batch-specific behavior an agent needs, such as whether the batch is atomic or can partially fail, validation/error semantics, and any rate limits.

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 with the core action front-loaded and the risk/auth caveat positioned at the end for emphasis. The mid-sentence field enumeration is slightly redundant against the schema but is not wasteful.

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 a real-money batch mutation with no annotations and no output schema, the description covers the safety-critical basics but leaves gaps on partial-failure/atomicity behavior and what is returned. It is adequate to call the tool, but not complete for an agent weighing the risk of a 100-order batch.

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 100% and the schema fully documents the nested order fields, so the baseline is 3. The description adds only a pointer to the `create_order` arg shape and a field list, which is largely a summary of what the schema already specifies.

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 and resource ('Submit multiple orders in one request'), making the batch nature clear and pointing at the per-order shape of `create_order`. However, it does not distinguish itself from the very similarly named sibling `place_orders_batch`, leaving the agent to guess which batch tool to pick.

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?

It supplies meaningful context ('Requires API credentials', 'submits REAL orders to the matching engine') that frames the circumstances for use. It never states when to prefer this over `create_order`, `place_order`, or `place_orders_batch`, so routing guidance is only implied.

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