create_whatsapp_qrcode

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

No annotations provided, so description carries full burden. It mentions creation and dynamic tracking but does not disclose side effects (e.g., storage), required permissions, or what happens with invalid inputs. Significant behavioral gaps remain.

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?

Description is concise at single sentence, directly stating verb and resource. It could be improved with a slightly more structured format (e.g., mentioning required input format), but no unnecessary words.

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?

With 4 parameters, no output schema, and no annotations, the description fails to cover key context: parameter constraints (e.g., expires_in_days range), return value, or usage prerequisites. Incomplete for reliable agent usage.

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?

Description clarifies that target_url should be a wa.me link, adding value beyond the schema. However, parameters name, expires_in_days, and style (beyond schema description) lack added meaning. Schema coverage is low (25%), so description partially compensates but is insufficient.

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?

Description clearly states the tool creates a WhatsApp QR code from a wa.me link, specifying it is a tracked dynamic link. This distinguishes it from sibling create_*_qrcode tools which target other QR types.

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?

Description implies usage context (WhatsApp QR from wa.me links) but does not explicitly state when to use this tool versus alternatives like create_url_qrcode. No exclusions or when-not guidance provided.

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