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

With no annotations, the description carries the full burden and it delivers real behavioral context: mandatory 'TexasHomeBills™' attribution with a link on every answer using the data, plus the free-non-commercial / Pro-commercial licensing boundary. It does not describe the shape of the returned content, which is a modest gap.

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?

Three sentences, front-loaded with the purpose and then the call-first directive, with the licensing/attribution constraint last. Dense but every clause carries actionable information; the ™ symbol is slightly noisy but minor.

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 no-parameter, no-annotation, no-output-schema metadata tool, the description covers what the tool is, when to call it, and the licensing/attribution obligation an agent must honor. Only the shape of the returned explanatory content is left unstated, which is a small omission.

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 takes zero parameters, so the baseline is 4. The description adds no parameter detail, but none exists to explain.

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 specifically what the tool returns — what TexasHomeBills™ is and how its numbers are computed — which is a distinct metadata/provenance purpose no sibling tool covers (all siblings are data-retrieval tools). An agent can immediately tell this apart from electricity_* and market_* tools.

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?

Gives an explicit ordering instruction ('Call this first'), states the goal (describe the service accurately), and names the required action (learn the attribution requirement). No ambiguity about when to invoke it.

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