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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the content type (gotchas, workarounds, severity levels) and geographic coverage (Spain, Portugal, general), which is genuinely informative. However, it does not explicitly declare read-only behavior or any side effects (e.g., that it performs no mutations), which is a minor gap for a search tool.

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 sentences with no wasted words. The core value proposition (search gotchas) is front-loaded, followed by key details (severity, workarounds, coverage). Every phrase earns its place, and the structure is easy to scan quickly.

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?

Given the 5 parameters are all schema-described and the domain is clear, the description conveys the essential scope and content. Since there is no output schema, it would benefit from briefly describing the return format (e.g., a list of gotcha items with severity and workaround fields), though it does hint at that via 'severity levels and workarounds'. Adequate but not exhaustive.

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?

All five parameters are fully documented in the schema (100% coverage), so the description adds little semantic value beyond what the schema already provides. Mentioning 'severity levels' aligns with the severity parameter but does not elaborate on filtered behavior or value syntax, meeting the baseline for schema-covered parameters.

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 identifies the specific resource (Expatriator's curated immigration knowledge base), the action (search), and the distinctive content ('gotchas' with severity levels and workarounds). It differentiates itself from siblings like get_procedure_guide by emphasizing real-world pitfalls rather than official procedures, making its purpose unambiguous.

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 implies this is the tool for finding documented immigration gotchas, but it never explicitly contrasts it with siblings like get_procedure_guide or list_procedure_guides. An agent must infer when to choose this over a step-by-step guide; no explicit when/when-not guidance is given.

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