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

There are no annotations, so the description carries the full burden. The description implies a safe, read-only listing by using 'List' and 'open dataset', and adds licensing context ('Free, CC BY 4.0'), but it does not explicitly state that no data is modified or describe any edge behaviors. For a parameterless list tool this is adequate but not rich.

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 states the action and resource, then immediately summarizes the output. The licensing note is brief and adds useful context without bloat.

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 zero-parameter tool with no output schema, the description fully covers what the agent needs: what is listed, what fields are returned, and the licensing/access conditions. Nothing essential is missing.

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 tool has zero parameters and the schema already reflects that completely. The description adds context about what the result contains (states, county counts, period range), which is more than necessary for parameter understanding, so the baseline-4 score 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?

The description clearly identifies a specific verb ('List') and resource ('states covered by Buckhead's open county-production dataset'), and even previews the output contents. It does not explicitly differentiate itself from sibling get_* tools, though its discovery-oriented nature is implicitly distinct.

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 about when to use this tool versus siblings like get_county_production or get_county_drilling_activity. An agent must infer that this is a discovery/preflight call for understanding dataset coverage rather than retrieving actual production data.

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