Update order memo

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

With no annotations provided, the description must fully disclose behavioral traits, but it only says 'update order memo (store-side internal memo)'. It fails to mention whether the memo is overwritten, required permissions, idempotency, side effects, or confirmation behavior, which is especially important for a write operation.

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 compact sentence that is front-loaded with the action and resource. There is no filler or redundant repetition of the title, making it highly concise.

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?

While the tool has low complexity (two string parameters and no output schema), the description is still incomplete: it lacks annotations, usage context, behavioral side effects, and parameter semantics. It only covers the basic purpose, leaving an agent with too little information for confident selection and invocation.

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 0% and neither parameter has a description in the schema. The description only clarifies that the memo is store-side internal, adding minimal value beyond the parameter names; it does not explain order_number format or memo constraints.

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 verb 'update' and the resource 'order memo', and adds the parenthetical 'store-side internal memo' clarifying scope. However, it does not explicitly differentiate this tool from sibling tools like rms_update_remarks, leaving some ambiguity.

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 usage guidance is provided: the description does not say when to use this tool, when not to use it, or mention alternative tools. The context signals also offer no hints, so an agent has no basis for selecting this tool over similar sibling tools.

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