lease_accounting__lease_liability

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

No annotations are provided, so the description bears full responsibility. It mentions the discount rate source (IBR or implicit rate) but fails to disclose behavioral traits like whether the calculation is for initial recognition or subsequent measurement, whether it assumes payments are in arrears unless specified, or what the output represents. The description is insufficient for a financial computation 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 a single sentence with no filler, but it is too brief to adequately convey the tool's purpose and usage. Concateness is achieved at the cost of completeness.

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 complexity of lease liability calculations and the absence of an output schema, the description should explain what the result represents (e.g., initial lease liability) and any key assumptions. It does not, leaving significant gaps for the agent.

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?

With 4 parameters and 0% schema coverage, the description adds almost no meaning. It mentions 'payment' and 'rate' implicitly but does not describe 'term_years' or 'in_arrears'. The agent receives no help beyond parameter names, making correct invocation difficult.

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 specifies the verb 'PV' and resource 'lease payments at the discount rate', clearly indicating it calculates the present value of level lease payments. It distinguishes from sibling tools like amortization_schedule and rou_depreciation, but the jargon 'PV' might be slightly ambiguous for non-expert agents.

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 (e.g., amortization_schedule, rou_depreciation). No explicit conditions or exclusions are provided, leaving the agent to infer usage from the tool name alone.

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