generate_print_certificate

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

The description discloses that the tool queries print history and builds a certificate, implying a read-only operation. However, it does not specify behavior for missing file_path, empty history, or potential side effects (none expected, but unstated). Annotations are absent, so description carries the burden but is only moderately complete.

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 concise, front-loaded with the primary purpose, and followed by a clear bullet of what the certificate contains. Every sentence adds 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?

For a simple tool with one parameter and no output schema, the description is adequate but lacks details on return format, error handling, or edge cases (e.g., missing history). It covers the core functionality but leaves minor gaps.

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 description includes an Args section that explains file_path as 'Path to the 3D model file,' adding meaning beyond the schema's type-only definition. Schema coverage is 0%, so description compensates well for this 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 states exactly what the tool does: generate a print 'birth certificate' for a 3D model by querying print history and building a certificate with specific contents. This is a unique verb+resource combination that clearly distinguishes it from sibling tools.

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?

No guidance on when to use this tool versus alternatives like get_model_print_history or analyze_print_failure. The description does not specify prerequisites or context, leaving the agent to infer usage.

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