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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so the safety profile is fully covered. The description adds only that pricing is 'current' and that metadata is 'public', which is modest added context but no rate limits, auth needs, or return detail.

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?

A single front-loaded sentence with no filler; the target object and the returned data are established immediately.

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 simple read-only lookup with no output schema, the description adequately signals what comes back ('current price and public metadata') and that it operates on a single ID. Only the ID format and usage relative to siblings are left unaddressed.

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?

One parameter with 0% schema description coverage, so the description must carry weight. It confirms the input is exactly one dataset product ID, but adds nothing about the required prefix pattern (city-trade|state-trade|state|mega-pack) that the schema encodes, leaving the format to the schema alone.

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 a specific verb and resource ('Get the current price and public metadata for one dataset product ID'), which distinguishes it from list_* and search_datasets siblings. It does not name any sibling explicitly, but the singular 'one dataset product ID' scoping makes the operation unambiguous.

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 versus search_datasets, preview_dataset, or get_coverage. The context (you must already have a product ID) is implied only by the phrasing, with no stated prerequisites or alternatives.

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