Mirabello Immigration Intelligence

Find Immigration Pathways

find_pathways

Read-onlyIdempotent

Find which countries offer a given immigration pathway (e.g. digital-nomad, skilled-work, ancestry-descent, retirement-passive, eu-free-movement). Returns the screened countries that have it, each with its key requirements (income thresholds included), cost and path to PR. EU/EEA/Swiss citizens moving within the EU/EEA or Switzerland use eu-free-movement, not a visa.

A3.9/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive and a closed-world dataset; the description adds genuinely new context by describing the shape of the result ('screened countries ... each with its key requirements (income thresholds included), cost and path to PR'). It does not contradict any annotation and hints that results come from a pre-screened set, though it says nothing about result size, ordering, or empty-result behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences, front-loaded with the core lookup question followed by return contents and an edge case. Slight redundancy in re-explaining eu-free-movement, which the schema already covers, keeps it from a 5.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need no full explanation, and the description covers purpose, output gist, and the key EU edge case. The one notable omission is any mention of the region filter, which an agent can only learn from the schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for both parameters, so baseline is 3. The description's list of example pathways largely restates the enum, and its eu-free-movement clarification duplicates the schema's own parameter description; it adds no region-filtering or matching semantics beyond what the schema states.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Find which countries offer a given immigration pathway') and enumerates example pathway ids, so an agent can immediately tell this is a reverse lookup by pathway rather than a per-country lookup like get_country or check_eligibility. The scope is further sharpened by describing what is returned (screened countries with requirements, cost, PR path).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the pathway enumeration, and there is one explicit routing rule ('EU/EEA/Swiss citizens moving within the EU/EEA or Switzerland use eu-free-movement, not a visa'), but that rule governs choosing a pathway value rather than choosing between this tool and siblings. No guidance is given on when to prefer this over find_retirement_routes, recommend_programmes, or check_eligibility.

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