withholding_tax_rates

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

There are no annotations, placing full burden on the description. The description only says 'DEMO,' which is ambiguous and does not disclose behavior such as whether data is real, what the response structure is, or any limitations. No read-only or safety information is provided.

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 very concise and front-loaded with the tool's purpose. However, the 'DEMO' sentence is cryptic and adds little actionable value, so it is not perfectly efficient.

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?

The tool is simple with one optional parameter and an output schema, so the description is nearly adequate. However, it lacks usage context, possible payment_type values, and an explanation of the 'DEMO' caveat, leaving gaps for an agent to resolve.

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 mentions 'by payment type,' which clarifies that payment_type is a filter, but it does not provide allowed values, formats, examples, or distinction between null and unspecified values. This is minimally helpful but insufficient for confident invocation.

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 clearly identifies the tool's topic ('Kenya withholding tax rates') and the dimension by which rates are organized ('by payment type'). It is distinct from the sibling tools like paye_calculator or vat_guide by tax type, though it does not explicitly name alternatives.

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 is provided on when to use this tool versus the sibling tools such as paye_calculator or vat_guide. The usage context is merely implied by the title and description, with no exclusions or alternative recommendations.

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