lease_accounting__rou_depreciation

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

The description discloses the method (straight-line) and the absence of residual value, but does not explain how the calculation is performed, whether it handles partial periods, or any assumptions. Without annotations, the agent lacks behavioral context such as error conditions or precision details.

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 that efficiently conveys the tool's purpose and key characteristics. It is well-structured and front-loaded with the domain tag. However, it could be expanded slightly to include parameter information 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 tool's simplicity (two parameters, no output schema), the description is incomplete. It does not specify that the output is likely the annual depreciation expense, nor does it provide any formula or calculation details. The agent lacks full context to interpret results correctly.

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?

The input schema has no descriptions for the two required parameters ('rou_asset' and 'term_years'), and the tool description does not mention them at all. With 0% schema coverage, the description must clarify parameter meanings, but it fails to do so, leaving the agent to guess what these parameters represent.

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 'Straight-line ROU depreciation (no residual)', clearly indicating the tool computes depreciation for a right-of-use asset using the straight-line method with no residual value. It distinguishes from sibling tools like lease_accounting__amortization_schedule and lease_accounting__lease_liability by specifying the type of depreciation.

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 alternatives, such as other depreciation methods or the lease_accounting__amortization_schedule. There is no mention of prerequisites or context for invocation.

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