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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint=false, so safety and determinism are covered. The description adds a useful provenance trait (published / model / manual labeling on every number), which is real behavioral value beyond annotations, but does not address aggregation method, caching, or freshness.

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?

Front-loaded with the imperative "Start here," then efficiently enumerates the returned content in two tight sentences. No waste, though slightly dense with enumerated dimensions.

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 single optional-param read-only overview tool with full annotations, the description covers content scope and provenance adequately. The main gap is disambiguation from siblings with overlapping-sounding content, which an orientation tool arguably should address.

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% with a single enum parameter fully documented in the schema, so the baseline is 3. The description adds nothing about the lang parameter or default behavior beyond what the schema states.

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 specific content: annual risk for five escalation levels across three time horizons plus intelligence tone per country. Clear what resource is returned, though it doesn't explicitly differentiate from get_risk_ladder or get_intelligence_assessments, which appear to cover overlapping content.

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?

"Start here" gives a strong implied usage cue for orientation, suggesting this is the entry-point tool. However, it does not explicitly say when to use this versus siblings like get_risk_ladder or get_intelligence_assessments, leaving the agent to infer overlap boundaries.

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