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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds the 7-day forecast window and the default threshold value, which is useful scoping context, but says nothing about return shape or ordering (and no output schema exists to compensate).

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 tight sentence that front-loads the resource and the filtering condition with zero wasted words. It is efficient, though its brevity is part of why routing and behavioral detail are missing.

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 read-only filter tool with full schema coverage and annotations, the essentials are present. Still, with no output schema and many sibling risk tools, the definition leaves the agent guessing about return format and how this differs from adjacent forecasting endpoints.

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 coverage is 100% and the single parameter's description already states range 0-1 and default 0.5, so the description's restatement adds little. Baseline 3 is appropriate when the schema does the heavy lifting.

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 resource (countries) and the exact filtering predicate (7-day forecast exceeding a risk threshold), so an agent understands the output set without opening the schema. It does not, however, differentiate itself from sibling risk tools like get_risk_forecast or get_shutdown_risk_leaderboard.

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 or when-not-to-use guidance, and no alternative is named despite a crowded sibling set containing several risk/forecast tools. The agent is left to infer selection from the name alone.

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