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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds that inputs are bounded and that domain errors are surfaced explicitly, which is useful behavioral context beyond the annotations, though it does not say what triggers an error.

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?

A single sentence with no filler, front-loading the core operation and appending the two constraints (bounded inputs, explicit domain errors). Every clause earns its place.

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 simple two-parameter math tool with an output schema, annotations, and full schema coverage, the description is nearly sufficient: it names the operation, notes input bounds, and warns of domain errors. It stops short of explaining which input combinations are outside the domain.

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% and both parameters ('base', 'exponent') are documented there with their min/max bounds. The description only restates the conceptual relationship (base raised to exponent) and adds no format or edge-case detail beyond the schema, so the baseline of 3 applies.

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 ('compute a real number raised to an entered exponent'), which is unambiguous and matches the title. However, it does not distinguish the tool from math siblings like logarithm, simplify_sqrt, or scientific_evaluate, so an agent must infer the boundary from the name alone.

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 statement of when to use this tool versus alternatives such as logarithm or scientific_evaluate, and no context about prerequisites or typical call scenarios. Usage is only implied by the name.

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