calculate_canada_combined_tax

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

Discloses the return fields in the output, including the abatement percentage. However, no annotations are provided, so the description carries the full burden; it is fairly transparent for a calculator 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?

Two sentences, front-loaded with the action, and includes a useful reference to related tools. Every sentence 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 (one parameter, no annotations, output schema exists), the description is relatively complete, showing output fields and a reference to related calculators.

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 100% and parameter description is adequate. The tool description adds no extra meaning beyond the schema's description of income_cad.

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?

Clearly states the tool calculates combined Quebec and federal income tax with the abatement, but does not explicitly differentiate from sibling tools like calculate_quebec_income_tax or calculate_canada_federal_tax.

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?

Provides a reference to list_bundles for related calculators, but lacks explicit guidance on when to use this tool versus alternatives.

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