get_gen_comparison

Compare generator forecast to actual output by plant and fuel type. See average percentage difference between MUSE forecast and Edison actual generation.

Instructions

Compare generator forecast vs actual output. Compares MUSE (forecast) vs Edison (actual/IIR) generation by plant and fuel type. Shows average percentage difference — positive means Edison produced more than MUSE forecast. Use this when asked about generator forecasts, forecast accuracy, MUSE vs Edison, plant output, or fuel-type generation.

TDQS

A3.9/5.0
Behavior3/5

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

No annotations exist, so description must carry full burden. It explains the calculation and data sources but omits behavioral traits like read-only nature, data freshness, or pagination. Adequate but not exhaustive.

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?

Two sentences: first defines purpose, second adds detail on meaning and usage. No fluff, every sentence adds value.

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

Completeness3/5

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

With no output schema, the description lacks detail on return format. It only mentions 'shows average percentage difference'. For a complex tool, more context on output structure would help.

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

Parameters3/5

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

Schema coverage is 100%, so baseline is 3. Description adds example fuel type values and notes partial match for plant_name, but does not significantly enhance understanding beyond the schema.

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?

The description clearly states it compares generator forecast (MUSE) vs actual (Edison) output, specifies the metric (average percentage difference), and explains directionality. This is specific and distinct from siblings like get_gen_detail.

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

Usage Guidelines4/5

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

Explicitly lists when to use: 'when asked about generator forecasts, forecast accuracy, MUSE vs Edison, plant output, or fuel-type generation.' Lacks explicit when-not or alternatives, but the context is clear.

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