generate_qr_urls_batch

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

With no annotations provided, the description carries the full burden. It discloses key behavioral traits: the tool generates download URLs, returns a ZIP file, and has a maximum batch size of 100 URLs. However, it lacks details on permissions, rate limits, error handling, or what happens if URLs are invalid, which are important for a batch processing tool.

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 front-loaded with the core purpose, followed by usage context and key constraints, all in three concise sentences with zero waste. Each sentence earns its place by adding value without 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?

Given the tool's moderate complexity (batch processing with 2 parameters) and no annotations or output schema, the description is adequate but has gaps. It covers the purpose, output format, and limits, but lacks details on authentication, error responses, or file naming conventions in the ZIP, which could be helpful for an agent.

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 description coverage is 100%, so the schema already fully documents both parameters. The description adds no additional meaning beyond what the schema provides, such as explaining parameter interactions or usage examples. Baseline 3 is appropriate when the schema does the heavy lifting.

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 specific action ('Generate QR code download URLs'), resource ('multiple URLs at once'), and distinguishes from siblings by emphasizing batch processing for multiple URLs versus single QR generation. It explicitly mentions the output format (ZIP file) and scope (max 100 URLs).

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 provides clear context for when to use this tool ('Perfect for batch processing CSV files or lists'), but does not explicitly mention when not to use it or name alternatives like 'generate_qr_code' for single URLs. It implies usage for bulk operations without detailing exclusions.

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