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

TableJSON Schema

Name	Required	Description
`error`	No	Present only when the request could not be fulfilled.
`terms`	No	Acceptable-use and information-not-advice terms.
`source`	No	Attribution for the data, when it is not Mirabello Consultancy itself.
`book_url`	No	Link to request a consultation with a Mirabello specialist, for a personal case.
`provider`	No	Always "Mirabello Consultancy".
`disclaimer`	No	Information, not legal/tax/financial/immigration advice; figures indicative.
`data_updated`	No	Date the underlying dataset was last updated.

TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds genuine context beyond that: the default return is truncated to the top 25, the full table is large, and insufficient-data programmes are flagged provisional and excluded from the headline ranking.

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?

Front-loaded with the resource identity, then dimensions and the default/limit behavior. Nearly every clause earns its place, though the parenthetical dimension list is dense and could be trimmed slightly without loss.

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?

With an output schema present, return values needn't be explained, and the description still covers default truncation, the limit:0 escape hatch, and provisional-data handling. Only the sibling-routing piece is absent, which is a minor gap for a two-parameter read tool.

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 100%, so the baseline is 3, but the description adds semantics the schema does not: the default limit is 25 and limit:0 is a documented sentinel meaning 'every ranked programme.' That sentinel behavior is nowhere in the schema and materially changes how an agent calls the tool.

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 resource (the Mirabello Investment Migration Index) and precisely what it is: a composite 0–100 ranking of CBI/RBI programmes across named dimensions. This distinguishes it from siblings like list_programmes (enumeration), compare_programmes (pairwise), and get_wealth_index (a different index). An agent can tell what it gets without opening the schema.

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

Usage Guidelines4/5

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

Gives clear operational context: filter by type, and the default of TOP 25 with limit to enlarge or limit:0 for the full table. What's missing is explicit routing against siblings such as list_programmes or compare_programmes, so an agent must infer when this index beats a plain programme list.

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