Investment Migration Index

get_index

Read-only

The Mirabello Investment Migration Index — a composite 0–100 ranking of CBI/RBI programmes across cost, mobility, speed, path-to-citizenship, stability, family and tax, with transparent published methodology. Filter by type (CBI/RBI) and limit. Returns the TOP 25 by default (the full table is large); pass limit for more, or limit:0 for every ranked programme. Programmes with insufficient verified data are flagged provisional and excluded from the headline ranking.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`type`	No	Programme family: "CBI" grants citizenship, "RBI" grants residence (golden visa). Omit for both.
`limit`	No	Maximum number of items to return. Responses can be large; use this to keep the answer small.

Output Schema

`error`	No	Present only when the request could not be fulfilled.

`source`	No	Attribution for the data.
`provider`	No	Always "Mirabello Consultancy".
`disclaimer`	No	Information, not legal/tax/financial/immigration advice; figures indicative.

TDQS

A4/5.0

Behavior4/5

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

The description goes beyond the readOnlyHint annotation by disclosing the default TOP 25 behavior, the effect of limit:0, and that provisional programmes are excluded from the headline ranking. This gives the agent useful behavioral context without contradicting annotations.

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

Conciseness5/5

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

The description is three sentences with no fluff. Key behavioral facts are front-loaded, and each sentence adds a distinct piece of information: what the index is, how to filter, and how provisional entries are handled.

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

Completeness5/5

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

For a tool with two optional parametersebschemas covering both and an output schema present, the description covers everything an agent needs: the default return size, how to get more or all results, and how data quality is flagged. No critical information is missing.

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

Parameters4/5

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

Schema coverage is already 100%, but the description adds meaning on top: it explains the default limit of 25, the special limit:0 semantics, and the type filtering purpose. This is genuinely helpful beyond the schema.

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

Purpose4/5

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

The description states a clear verb and resource: it returns a composite 0–100 ranking of CBI/RBI programmes, and covers the major dimensions assessed. It is specific enough to be understood, though it does not explicitly differentiate itself from sibling tools like get_wealth_index or compare_programmes.

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?

The description explains how to filter and limit results, including the default TOP 25 behavior and the special limit:0 option. However, it does not provide explicit guidance on when to use this tool versus alternative ranking/comparison tools among the many siblings.

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