create_file_qrcode

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

No annotations are provided, so the description carries full burden. It mentions file size limit and download behavior for file_url, but lacks details on persistence, authentication, or error handling. Adequate but not comprehensive.

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?

Two sentences, front-loaded with the core purpose, followed by essential details. No redundant words, earning its place.

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 the complexity (7 params, no annotations, no output schema), the description covers the core purpose and key constraints (file sources, types, size). However, it does not explain several parameters or return behavior, leaving the agent with incomplete guidance.

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?

Only the 'style' parameter has a schema description (14% coverage). The description adds meaning for the three file input parameters by naming them and explaining how they work. However, it does not explain 'filename', 'name', 'expires_in_days', or 'style' in detail, leaving gaps.

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 file/document QR codes, including how to provide the file (file_path, file_url, file_base64), accepted file types, and size limit. It distinguishes from sibling tools like create_url_qrcode by targeting files specifically.

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 how to provide the file via three methods, but does not explicitly contrast with alternatives or state when-not-to-use. However, the sibling tool names and context imply the distinction, leaving room for minor improvement.

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