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

With no annotations provided, the description carries the full burden of behavioral disclosure. It reveals the creation action and a limit of 200 codes, but omits details such as error handling on exceeding the limit, atomicity, response format, or whether the operation is synchronous. This is adequate but not thorough.

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 extremely concise with two sentences, no wasted words, and front-loaded with the core action. It efficiently conveys the essential purpose and a key requirement.

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 bulk creation tool with no output schema and moderate complexity, the description is too sparse. It fails to explain what happens on success (e.g., response includes created codes), how partial failures are handled, or if the operation is synchronous. The sibling tool 'create_dynamic_qr' may provide some context, but the description should be more self-contained.

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% (both parameters have descriptions in the schema). The tool description does not add any additional meaning beyond what the schema already provides. The mention of 'up to 200' is a constraint on the array, not a parameter attribute, and is not part of the schema.

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 action ('Create'), the resource ('dynamic QR codes'), and the key differentiator ('up to 200 at once'), which distinguishes it from the sibling tool 'create_dynamic_qr' that creates a single code. The API key requirement adds necessary context.

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 provides a prerequisite ('Requires an OpenQR API key'), which is useful for usage. However, it does not explicitly state when to use this tool over its single-code sibling or indicate any exclusions or context where it should not be used.

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