Mobility Optionality

get_mobility_optionality
Read-only

Strategic mobility optionality for a jurisdiction: the lawful residence/citizenship ROUTES it offers (investment programmes) with minimum physical presence, family inclusion, path to permanence, processing time and regulator — the planning view of mobility, not passport strength. Passport reach (visa-free count) is included as context only. Pass cc for one jurisdiction, omit for all. INFORMATION, NOT ADVICE; combine with the full immigration profile and a Mirabello consultation.

TDQS

A4.3/5.0
Behavior4/5

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

Annotations already declare readOnlyHint/non-destructive/closed-world, so safety is covered. The description adds value beyond them: it flags the output is informational not advice, scopes passport reach as context-only, and instructs combining with a consultation — useful framing not present in structured fields. It says nothing about rate limits or caching, but that is minor given the annotations.

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 core purpose, then supporting attributes and caveats. The main sentence is dense with em-dashes and parentheticals, but each clause carries signal (attributes, disambiguation, parameter behavior, disclaimer) rather than filler.

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?

For a single-optional-param, read-only tool with an output schema and full annotations, the description supplies the missing conceptual context: what counts as 'mobility optionality,' how it differs from passport strength, and the informational-not-advice framing. Nothing essential for a correct call is absent.

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% with a well-documented cc parameter, so the baseline of 3 applies. The description adds genuine semantics beyond the schema by explaining the optionality — 'pass cc for one jurisdiction, omit for all' — clarifying the no-argument behavior, which the schema alone does not convey.

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+resource: it returns the lawful residence/citizenship routes a jurisdiction offers (investment programmes) along with defined attributes (physical presence, family inclusion, path to permanence, processing time, regulator). It explicitly distinguishes itself from passport-strength tools by contrasting the 'planning view' with 'passport strength' and noting visa-free count is context only, so an agent can separate it from check_visa_free/list_visa_free_destinations without opening schemas.

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 context for use (jurisdiction-level planning of mobility optionality) and states 'Pass cc for one jurisdiction, omit for all,' plus the caveat to combine with the full immigration profile and a consultation. It does not explicitly name a competing sibling (e.g. check_visa_free or compare_programmes) as the alternative, so routing is inferred rather than spelled out.

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