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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that results carry weights, hinting at the return shape, but says nothing about ordering, granularity, or what 'triggers' are beyond the name.

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 with no padding, and the returned content is front-loaded before the usage hint. The opening fragment lacks a verb, which slightly weakens the front-loading but keeps it compact.

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?

With no parameters and no output schema, the description must carry the full burden of explaining the return. It says results include weights but not what a 'trigger' is, how weights are scaled, or how it differs from get_geo_trigger, leaving a meaningful gap for an agent trying to interpret output.

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 there is nothing for the description to disambiguate; baseline for a no-param tool applies. The description does not need to explain argument semantics because none exist.

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?

'Geo triggers with weights' is a noun fragment rather than a verb+resource statement, but combined with the second sentence it conveys that the tool returns geo factors with weights contributing to the risk score. It does nothing to distinguish itself from the similarly named sibling get_geo_trigger, leaving an agent unsure which to pick.

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?

The second sentence gives an explicit trigger condition: call it when you need to see which geo factors drive the risk score. That is clear usage context, though it states no exclusions and does not route the agent away from get_geo_trigger or get_geo_energy_flows.

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