trybiut_tax_calculate

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

With no annotations, the description carries the full behavioral burden. It adds 'No login needed' and the qualifier 'basic', but it does not disclose whether the calculation is read-only, whether it depends on current tax rates, whether it stores data, or what the response looks like. This is thin coverage for an unannotated 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?

The description is compact and front-loads the core purpose in the first sentence. The second sentence adds a useful accessibility trait. It could be more informative without being verbose, but there is no wasted wording.

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 tool with five parameters, no output schema, and no annotations, this description is incomplete. It omits the role of period and includeSocialSecurity, the meaning of 'basic', the return format, and any behavior beyond 'no login'. The schema fills some gaps with defaults and enums, but not enough for reliable invocation.

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 description coverage is 0%, so the description must compensate. It names amount, region, and business type, but it does not explain 'period' or 'includeSocialSecurity' meaning, currency, or how the values interact. The schema provides names and defaults, but the description adds little beyond restating a few parameter names.

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 a clear purpose: producing a 'basic tax breakdown' for an amount, region, and business type. It names the core inputs and implies a calculation outcome, but it does not explicitly distinguish itself from siblings like trybiut_tax_preview or trybiut_tax_history.

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?

There is no guidance about when to use this tool versus alternatives such as trybiut_tax_preview or trybiut_tax_calendar. 'No login needed' provides a context signal but does not explain selection criteria or exclusions, leaving agents to guess which tax-related sibling fits.

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