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

With no annotations, the description carries the burden of disclosure. It adds useful context: 'AI-synthesized' alerts, 'deterministic USGS primitive' for quake-check, and per-endpoint pricing. However, it omits response formats, auth requirements, and error behaviors, so transparency is partial.

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?

The description is well-structured with a front-loaded summary and a bulleted endpoint list. Each line adds value (capability and price), and the length is appropriate for an 11-endpoint tool. Slight verbosity from pricing is acceptable.

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?

This is a complex multi-action tool with 18 parameters and no output schema. The description fails to explain which parameters are relevant for each action (e.g., 'countries' for compare, 'entity' for sanctions). Without this mapping, an agent may struggle to invoke the correct endpoint with the right parameters.

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%, so baseline is 3. The description adds meaning beyond the schema by associating each action enum value with a one-line semantic and price, improving the agent's understanding of what each endpoint does. It does not map specific parameters to actions, but the parameter names are self-descriptive.

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?

The description clearly states it is a 'Global risk intelligence API' and enumerates specific capabilities (travel safety alerts, country risk profiles, sanctions screening, etc.), making it distinct from sibling tools with different domains. The verb is implicit but the resource and scope are explicit.

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 description lists endpoints and their purposes, implying when to use the tool (e.g., for country risk, travel safety). However, it provides no explicit when-not-to-use guidance or mentions alternative sibling tools, so the agent must infer selection based on the endpoint list alone.

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