download_qrcode_file

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

With no annotations, description discloses behavior: write to path if save_path provided, else base64 (small files only). This reveals a limitation (base64 for small files) and implies mutation (file write). Missing details on error cases or prerequisites, but overall informative.

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, efficiently front-loaded with core behavior and alternative modes. No wasted 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?

Given no annotations and 0% schema coverage, description covers main behavior and save_path but lacks explicit id description and full constraints. Output schema may compensate, but overall completeness could be improved.

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 0%, so description must explain parameters. It explains save_path behavior and implies id identifies the QR code, but id is not explicitly described. Adequate but not thorough.

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 it downloads the current file of a file-backed QR code, with specific behavior based on save_path. It distinguishes from siblings like get_qrcode_png and get_qrcode_svg by focusing on the file download, not image rendering.

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 sets clear context: it's for file-backed QR codes and explains two usage modes (with/without save_path). However, no explicit when-not or alternative tool guidance provided, leaving some ambiguity.

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