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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description adds nothing beyond the HTTP path — no note on what happens when the id does not exist, whether the response is a single object or enveloped, or any auth/permission context.

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?

Two short fragments, zero padding, and the key qualifier ('one asset') is front-loaded. It is arguably over-trimmed, but no sentence is wasteful.

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 one-parameter read with full schema coverage and annotations, the essentials are present. However, with no output schema, the description gives no hint about return shape (asset object fields) or not-found behavior, leaving a modest gap.

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 coverage is 100% and the single asset_id parameter is documented in the schema with type and constraint. The phrase 'by id' restates the schema rather than adding format or lookup semantics, so baseline 3 applies.

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?

States the verb+resource precisely (fetch a single asset by its id) and the underlying endpoint, which implicitly distinguishes it from fieldpulse_list_assets. It does not name the sibling list tool explicitly, so differentiation is inferred rather than stated.

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 versus fieldpulse_list_assets or fieldpulse_list_asset_categories, and no prerequisites or error conditions mentioned. The agent must infer that an id is required and that listing is a separate tool.

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