Describe the Texas RRC wellbore dataset

describe_texas_wellbores

Free, no API key required. Describes the Texas Railroad Commission wellbore identity dataset decoded from RRC's EBCDIC mainframe corpus: the exact fields available, row count, freshness, pricing, and which parts of the source are NOT yet parsed. Returns no records. Call this before search_texas_wellbores.

A4.9/5.0
Behavior5/5

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

With no annotations, the description carries the full burden and discharges it: it discloses the auth profile (free, no API key), the non-mutating nature ('Returns no records'), and data-quality limits ('which parts of the source are NOT yet parsed'). Freshness and pricing are also surfaced, which an agent cannot infer from an empty schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences with zero waste. The most decision-relevant facts (free, no key, no records, call before the search sibling) are all front-loaded before the detailed field list.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and no parameters, the description fully covers what the agent needs: access requirements, the nature of the return (metadata, not records), the specific metadata categories, and routing to the companion search tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so the baseline is 4 per the rubric. The description correctly adds nothing about parameters because there is nothing to parameterize, keeping focus on the metadata payload.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (describes) and resource (Texas RRC wellbore identity dataset), and enumerates the exact metadata returned: fields, row count, freshness, pricing, and unparsed source. It explicitly distinguishes itself from the sibling search_texas_wellbores by noting it 'Returns no records' and directing the agent to call it first.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit routing rule: 'Call this before search_texas_wellbores,' which names the alternative tool and the condition selecting it. Access guidance ('Free, no API key required') is also front-loaded, leaving nothing to inference about when this tool is appropriate.

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