modify_order

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only repeats the tool's purpose and adds a vague claim about order varieties. It fails to mention authentication needs, side effects, order status constraints, or response format, leaving significant behavioral gaps.

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 a single concise sentence with no redundant words, earning points for conciseness. However, it lacks structure and is arguably too terse for a tool with 9 parameters, so it does not reach a perfect score.

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 mutation tool with 9 parameters, no annotations, and no output schema, the description is severely incomplete. It does not explain return values, error conditions, or how different order varieties affect the modification process. The claim 'all order varieties' is vague and unsubstantiated.

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 input schema has 100% description coverage for all 9 parameters, so the baseline is 3. The description adds no extra meaning beyond the schema, but it does not need to because the schema already documents each parameter clearly.

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 'Modify an existing order' which identifies the specific action and resource. There is no sibling tool with a similar modify function, making it unambiguous. The phrase 'with support for all order varieties' adds a capability claim, though somewhat vague.

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 guidance is provided on when to use this tool versus alternatives like canceling and recreating an order, or using the various place_* tools. The description does not mention any exclusions or specific scenarios where this tool is appropriate.

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