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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions data types ('demand, generation, and interchange data') but lacks critical details like rate limits, authentication requirements, error handling, or response format. For a tool with 7 parameters and no output schema, this leaves significant gaps in understanding its operation.

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?

The description is efficiently structured in two sentences, front-loading the core purpose and including a data source note. It avoids redundancy and waste, though it could be slightly more informative without sacrificing brevity.

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?

Given the tool's complexity (7 parameters, no annotations, no output schema), the description is inadequate. It doesn't explain return values, error conditions, or behavioral traits like pagination (implied by 'limit' parameter) or data freshness. For a data retrieval tool with multiple options, more context is needed to guide effective use.

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 description coverage is 100%, so the schema already documents all parameters thoroughly. The description adds minimal value beyond the schema by implying the tool handles 'hourly and daily' data, which relates to the 'route' parameter's enum options. However, it doesn't provide additional syntax, examples, or constraints, meeting the baseline for high schema coverage.

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 states the tool's purpose: 'Get hourly and daily electric power operations by balancing authority (Regional Transmission Operator).' It specifies the verb ('Get'), resource ('electric power operations'), and scope ('by balancing authority'), though it doesn't explicitly differentiate from sibling tools like 'eia_electricity_operational_data' which might overlap in domain.

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 on when to use this tool versus alternatives. The description mentions the data source ('Form EIA-930') but doesn't specify use cases, prerequisites, or comparisons to sibling tools such as 'eia_electricity_operational_data' or 'eia_electricity_state_profiles', leaving the agent without contextual direction.

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