tax_planning__deferral_benefit

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

With no annotations, the description bears full responsibility for behavioral disclosure. It only states the purpose but does not describe the calculation logic, assumptions, or limitations. For a tool that computes a present value saving, details like formula or edge cases are missing.

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 a single, front-loaded sentence that efficiently conveys the core purpose. While very concise, it avoids redundancy and is easy to parse. However, it could benefit from slightly more detail without losing conciseness.

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 lack of an output schema and the tool's computational nature, the description should clarify the return value (e.g., a numeric present value saving) and any underlying assumptions. It does not mention the output format or formula, leaving the agent uncertain about what to expect.

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 three parameters (tax_amount, years_deferred, discount_rate) and implies their roles through the tool's purpose. However, it does not explain units, expected ranges, or how they interact, providing only marginal added meaning.

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 states it calculates 'PV saving from postponing a tax payment', indicating a specific financial metric. The verb and resource are clear, and the name 'deferral_benefit' helps differentiate from other tax planning tools like marginal_rate or effective_rate, though no explicit sibling differentiation is provided.

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 on when to use this tool versus alternatives. The description does not mention prerequisites, scenarios, or limitations. Among siblings like tax_planning__marginal_rate, the context for choosing one over the other is absent.

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