Mirabello Immigration Intelligence

Investment Migration Index

get_index

Read-onlyIdempotent

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.

TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare read-only, idempotent, closed-world behaviour, so the bar is lower; the description adds the non-obvious default truncation to 25 items and the provisional-flag exclusion rule, which materially affect results. It doesn't mention rate limits or auth, but none are implied for a static index.

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-loads what the index is, then the filtering and default-vs-limit behaviour. Slightly dense as a single paragraph, but every sentence carries operational information and nothing is padding.

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-shape explanation isn't needed, and both parameters are fully documented. The description covers defaults, truncation and exclusions; what remains implicit is how the ranking behaves with both filters off, which is minor.

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; the description goes beyond the schema by defining the magic value limit:0 (return all) and the default of 25, which the schema does not state. The type enum semantics are already fully documented in the schema.

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 noun+verb: a composite 0–100 ranking of CBI/RBI programmes with named ranking dimensions, filterable by type and limit. This is clearly distinguishable from siblings such as list_programmes, compare_programmes or get_wealth_index without opening any 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?

Explains the default behaviour (top 25), how to get more (pass limit) and how to get everything (limit:0), plus the exclusion of provisional programmes. It doesn't explicitly contrast with an alternative sibling like compare_programmes, so it falls short of a 5.

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