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

The annotations only provide hints (readOnlyHint=false, destructiveHint=false), and the description does not add meaningful behavioral context beyond stating it updates and returns details. It does not disclose partial-update semantics, failure modes, permissions, or side effects, which would be valuable for a mutation 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 compact and well-structured with a lead sentence, an Args section, and a Returns section. Each line serves a purpose and there is no redundant or off-topic content.

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?

For a 5-parameter mutation tool with no output schema and no schema descriptions, the description is too thin. It omits details about partial updates, error handling, permissions, and the exact structure of the returned updated asset, leaving gaps an agent must resolve elsewhere.

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 schema description coverage at 0%, the description must compensate, and it does provide short definitions for each parameter like 'New name' and 'Updated current value'. However, these largely paraphrase the parameter names and do not explain formats, constraints, units, or currency expectations, offering only minimal 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 the action ('Update') and the resource ('a hard asset's details'), so an agent can identify the tool's purpose. However, it does not explicitly differentiate itself from sibling tools like create_hard_asset or delete_hard_asset, relying on the name rather than explicit contrast.

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?

There is no guidance on when to use this tool versus alternatives, such as create_hard_asset for new assets or list_hard_assets for viewing. No prerequisites, such as the asset existing or ownership requirements, are mentioned, leaving the agent to infer usage.

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