sympy_zeros

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

No annotations and description does not disclose any behavioral details such as default parameter behavior (e.g., cols defaults to same as rows) or return type. Minimal transparency for a simple creation function.

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?

Single sentence, no redundancy. All words serve a purpose.

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 existence of an output schema and the need to understand default behavior (cols=0 means same as rows), the description is too brief. Does not explain the result type or that default behavior of cols.

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 already provides 100% coverage for both parameters (rows, cols) with clear descriptions. Description adds no additional meaning, so baseline score of 3 is appropriate.

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 uses specific verb 'Create' and resource 'zero matrix', clearly distinguishing it from sibling tools like sympy_ones (ones matrix) and sympy_eye (identity matrix).

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. Does not mention that for non-zero matrices one would use sympy_matrix or other creation tools.

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