GST Quick Method Analysis

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

No annotations are provided, so the description carries the burden of behavioral disclosure. It states the tool compares methods and shows savings, and includes an eligibility threshold. However, it doesn't disclose assumptions (e.g., how is_reseller affects the calculation) or the exact nature of the output, which would be valuable.

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 two sentences, front-loaded with the primary purpose and followed by the eligibility constraint. Every sentence earns its place, with no redundant or filler content.

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?

With no output schema and no annotations, the description covers purpose, eligibility, and expected result. It doesn't explain how the optional is_reseller parameter factors into the analysis, but for a calculator tool, this is a minor gap. Overall the description is reasonably complete.

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 input schema provides 100% description coverage for all three parameters, with clear definitions. The tool description adds eligibility context but no additional parameter semantics beyond what the schema already provides, so the baseline 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?

The description uses a specific verb ('Compare') and names the resource ('Quick Method of accounting vs. regular GST method'), and states the outcome ('Shows potential savings'). This clearly distinguishes it from sibling tools such as calculate_gst or gst_registration_assessment.

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 gives a clear eligibility condition: 'Available for businesses with annual taxable supplies up to $400,000.' This tells the agent when the tool is applicable, but it doesn't explicitly name alternatives or state when not to use it, hence the slight deduction.

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