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

The annotations correctly indicate a non-read-only, non-destructive update, and the description matches. No hidden side effects such as depreciation recalculation or disposal implications are disclosed, but there is no contradiction with the annotations.

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 concise sentence with no redundant wording. It lightly expands the title without introducing unnecessary detail.

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?

With a rich schema covering all parameters, the description is sufficient for identifying the update operation. It does not mention return values, but the lack of an output schema lowers that requirement, and the schema fills most contextual gaps.

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 schema covers 100% of parameters with detailed individual descriptions, so the description adds little beyond broad category labels. The baseline of 3 applies because the schema already supplies the needed parameter semantics.

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 action (update), the resource (fixed asset), and the scope (by id, with fields like name, value, and depreciation settings). It distinguishes the tool from create_asset and other update_* siblings, though 'purchase date' is mentioned without a matching schema parameter.

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?

The description implies an existing asset by id but does not explicitly state when to prefer this over create_asset or the dedicated link/unlink asset-transaction endpoints. It provides no alternative-tool guidance or exclusionary conditions, leaving usage context only partially conveyed.

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