create_url_qrcode

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

Without annotations, the description carries the full burden. It reveals the static/dynamic behavior and its implications (e.g., no scan tracking for static). However, it omits other behavioral traits like authentication requirements, side effects, or whether the QR code is immediately downloadable.

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 two sentences long, front-loaded with the core purpose, and each sentence adds value. No redundant or irrelevant information.

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?

Given no output schema and 5 parameters, the description should mention return values or how the tool integrates with the ecosystem (e.g., whether it creates a QR code file, stores a record). The description lacks this context, leaving the agent under-informed.

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 only 20% (only `style` has a description). The description adds meaning only for the `static` parameter. Other parameters like `target_url`, `name`, and `expires_in_days` remain unexplained, failing to compensate for low schema coverage.

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 'Create a Website-link QR code,' using a specific verb and resource. It effectively distinguishes this tool from sibling QR code creation tools (e.g., create_email_qrcode, create_wifi_qrcode) by focusing on URL-based QR codes.

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 explains when to use static vs dynamic links, providing clear context for the `static` parameter. However, it does not discuss when to use this tool versus other URL-related tools or provide exclusions, leaving some ambiguity for the agent.

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