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

No annotations are provided, so the description carries the full burden. It correctly implies a safe read-only enumeration and even discloses the return fields, but it omits pagination, authentication, or result-size context. For a zero-parameter read tool this is adequate but not rich.

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 front-loaded sentence that names the resource and the fields returned with zero wasted words.

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, parameterless, read-only listing with no output schema and no annotations, the description supplies what an agent needs: what it lists and what fields come back. Missing only minor behavioral detail like result volume or pagination.

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 no parameters (0 required, 0 total), so there is nothing to document; the baseline for a parameterless tool is 4. The description adds no misleading parameter claims.

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 (list) and resource (Spanish procedure guides), and enumerates the returned fields (procedure code, name, provinces covered), which lets an agent distinguish it from the singular get_procedure_guide sibling. Differentiation from siblings is implicit rather than explicit, so it stops short of a 5.

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?

Usage is implied by the discovery-style listing ('list the ... guides Expatriator can provide'), but there is no explicit when-to-use statement, no mention of prerequisites, and no reference to alternatives such as get_procedure_guide or search_immigration_knowledge.

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