get_qrcode

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

With no annotations, the description provides limited transparency. The verb 'Fetch' indicates a read-only operation, and it adds a specific detail about dynamic codes' redirect URL. However, it does not disclose error handling, authentication needs, or response structure, leaving the agent to infer these.

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 sentence, front-loaded with action and resource, with no filler words. Every word contributes meaning.

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?

The tool is simple with one parameter and no output schema. The description explains what is returned (full details including redirect URL for dynamic codes), which covers the core outcome. It could be slightly more explicit about the response format, but it is sufficient for this complexity.

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?

The schema defines `id` as an integer but gives no meaning beyond that. The description directly states that the tool fetches by id, clarifying that the parameter represents the QR code's identifier. This compensates for the 0% schema coverage adequately for a single parameter.

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 ('Fetch'), the resource ('full details for one QR code'), and the scope ('by id'). It distinguishes from siblings like list_qrcodes (list all) and get_qrcode_analytics (analytics) by focusing on a single QR code's details.

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 implies when to use the tool (to fetch one QR code's full details by id), but it does not explicitly compare against alternatives like list_qrcodes or get_qrcode_analytics. There is no stated exclusion or preference for sibling tools.

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