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

With no annotations, the description carries the full burden of disclosing behavior. It explicitly states that the order is subject to pre-trade risk limits and that the handler uses the middleware-approved intent rather than re-parsing arguments. This is valuable insight into how arguments are treated and that the call will not be re-interpreted.

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 concise: two sentences. The first sentence is a direct summary, and the second explains the middleware/handler relationship. Every sentence serves a purpose, though the second paragraph is slightly more detailed than strictly necessary for a tool description.

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 tool with 7 parameters and no schema-level descriptions, the description does not compensate by explaining required inputs or order behavior. The output schema exists but is not shown, so the agent lacks critical information to construct a valid order request. The middleware context is interesting but does not fill the parameter gap.

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?

The description provides zero information about any of the 7 parameters. Schema coverage is 0%, so the agent has no help understanding what 'symbol', 'side', 'qty', 'order_type', 'limit_price', 'time_in_force', or 'client_order_id' mean or how they should be formatted.

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 opens with 'Submit an order,' which clearly identifies the specific action and resource. It is unmistakably distinct from sibling tools like get_quote or get_positions, which are read-only market data or account tools.

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?

No explicit guidance is provided on when to use this tool versus alternatives. The mention of pre-trade risk limits and middleware approval describes internal constraints but does not help an agent decide whether to call this tool or another one.

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