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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds genuine domain context that annotations cannot: nameplate MW is inventory, not available power or interconnection capacity. It still omits behavior on a missing/invalid plant_id and says nothing about ordering or page exhaustion.

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?

Two short sentences, front-loaded with the primary action and immediately followed by the caveat that prevents the most likely misreading of the data. Nothing is padded, though the trailing sentence does not connect to any parameter or usage decision, leaving the definition feeling slightly clipped.

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?

An output schema exists, so return-value documentation is not required, and the annotations cover the safety profile. However, for a three-parameter tool with zero schema description coverage, the description leaves both pagination parameters and the plant_id format undocumented, which is a meaningful gap for correct invocation.

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 0%, so the description must carry parameter meaning and largely does not. "Bounded page of generators" weakly signals that generator_limit/generator_offset are pagination controls, but there is no explanation of the plant_id format (a 1-12 digit numeric string) or of the 1-100 / 0-1000 bounds and defaults.

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 a specific verb and resource ("Get a power plant") plus the secondary return ("a bounded page of generators"), which separates it from siblings like get_plant_energy_history or get_regional_energy. It stops short of naming any sibling explicitly, so differentiation relies on the agent inferring from the resource noun.

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?

There is no when-to-use guidance and no exclusions; the description never says when to pick this over get_plant_energy_history, get_regional_energy, or get_transfer_capacity. Usage is only implied by the resource name, which is weak given how many plant-adjacent siblings exist.

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