QR for Agent

bulk_create_qr_codes

Create up to 50 QR codes in a single request with customizable options like format, colors, and logos. Ideal for batch generating QR codes for product catalogs or event lists. All-or-nothing quota check ensures no partial creation.

Instructions

Create multiple QR codes in a single request (up to 50). Each item supports the same options as create_qr_code. The quota check is all-or-nothing: if the batch would exceed your plan limit, no QR codes are created. Ideal for generating QR codes for product catalogs, event lists, or batch operations.

A4.4/5.0

Behavior4/5

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 usefully reveals the all-or-nothing quota check (if batch exceeds limit, no codes created) and the 50-item limit. However, it omits details on success/failure responses, partial error handling, or authentication/authorization requirements.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences with no wasted words. The first sentence states the core function and limit, the second adds the key behavioral trait (quota check) and typical use cases. Information is front-loaded and easy to parse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the primary function, constraints, and use cases adequately for a batch creation tool. However, it lacks explanation of the return value (e.g., created QR code IDs or errors), which is a gap since no output schema exists. Prerequisites like authentication are also absent, but these are often implied.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds value by stating each item supports the same options as create_qr_code, which helps the agent understand the parameter semantics without repeating field details. This provides meaningful context beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool creates multiple QR codes in one request (up to 50), explicitly references the sibling create_qr_code for individual options, and lists concrete use cases (product catalogs, event lists, batch operations), distinguishing it from other bulk tools like bulk_create_from_csv.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context for when to use (batch operations, product catalogs) and includes a critical constraint (all-or-nothing quota check). However, it does not explicitly state when to avoid using this tool (e.g., for fewer than 50 QR codes where create_qr_code may suffice) or mention alternatives beyond the sibling list.

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