create_qrcode

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

With no annotations, the description discloses key behavioral side effects: saving the QR code, appearing on the dashboard, and being tracked. It also mentions per-plan limits for dynamic codes. However, it does not disclose what happens when the limit is exceeded or the response format, but the provided context goes beyond a minimal description.

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 three sentences, efficiently front-loaded with the primary action. Each sentence adds value: the main purpose, the input approach, and the plan limits with an alternative. There is no fluff or redundancy.

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 moderately complex create operation with no output schema, the description adequately covers what the tool does, how to use it, and important constraints (plan limits). It could mention the response or error behavior, but the existing info suffices for selecting and invoking the tool, especially given the sibling differentiation and parameter explanations.

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 covers 67% of parameters, and the description compensates for the undocumented 'type' and 'content_type' by explaining their roles ('Pick a content type and pass the content as a string' and contrasting static vs dynamic). It adds meaning beyond the enum values, though it does not elaborate on all parameters like bg_color/fg_color, which are already described in 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 tool creates and saves a QR code in the customer's account, with explicit mention of dashboard appearance and tracking. It distinguishes itself from render_styled_qrcode, which only renders without saving, providing clear resource and action specificity.

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?

Provides explicit guidance on when to use this tool versus the alternative render_styled_qrcode, stating 'To just render a styled image without saving, use render_styled_qrcode instead.' Also explains the difference between static and dynamic codes and plan limits, helping the agent choose the appropriate type.

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