compare_lumpsum_vs_sip

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

No annotations are provided, so the description must carry the full burden. It only states what the tool compares but does not disclose behavioral aspects like output format, assumptions (e.g., SIP frequency), or that it is a pure calculation without side effects.

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 extremely concise with two sentences, front-loading the purpose and defining key terms. Every word adds value.

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 simplicity of the tool and the presence of an output schema (not shown but indicated), the description is adequate for basic understanding. However, it lacks details about the comparison output format or any assumptions about SIP frequency (e.g., monthly), which could improve completeness.

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%, and the description does not add meaningful detail beyond the parameter names. It states 'total_amount', 'annual_return', and 'years' but omits units, decimal/percentage format, or constraints (e.g., non-negative).

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 tool name and description clearly state it compares lump sum vs SIP investment for the same total amount, with explicit definitions of each. This distinguishes it from sibling tools like calculate_sip_returns or calculate_future_value.

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 (comparing two investment strategies) but does not explicitly exclude other cases or mention alternatives. The unique comparison logic makes it distinct enough.

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