Residence Evidence Checklist

residence_evidence_checklist

Read-onlyIdempotent

Tax-residence TESTS + evidence factors for a jurisdiction: day-count thresholds, statutory test (e.g. UK SRT), connecting/ties factors (permanent home, centre of vital interests, habitual abode, family, accommodation, economic links), how residence ceases, and the documentary evidence that proves residence start/cease. Use when someone moves and asks what proves they left their old tax residence or started the new one. Tests and factors only — NOT a residence determination. ISO alpha-2 code or country name.

TDQS

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false, and destructiveHint=false. The description adds behavioral context beyond annotations by clarifying that the output is a checklist of tests/evidence, not a determination, which helps prevent misuse. It does not contradict any annotation.

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?

The description is front-loaded with the core purpose and content, then usage context, then scope limit and parameter note. It is dense but every sentence carries information, though it could be slightly more structured with line breaks or bullet-like separators.

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?

Given the tool's complexity, the description covers what it returns (tests and factors), when to use it, and a critical scope limit. An output schema exists, so return-value details are covered elsewhere. The only minor gap is lack of explicit alternatives for residence determination tasks.

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 coverage is 100%, so the parameter meaning is fully documented in the schema. The description repeats the accepted input format ('ISO alpha-2 code or country name') but adds no new syntax or constraints beyond what the schema already provides.

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?

The description states a specific verb+resource: 'Tax-residence TESTS + evidence factors for a jurisdiction' and enumerates the exact content (day-count thresholds, statutory test, connecting factors, cessation, documentary evidence). It distinguishes itself from siblings like get_country_tax and get_document_checklist by focusing narrowly on residence tests and evidence for moves, and explicitly limits scope ('Tests and factors only — NOT a residence determination').

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?

It gives a clear when-to-use: 'Use when someone moves and asks what proves they left their old tax residence or started the new one.' It also includes an explicit scope exclusion ('NOT a residence determination') but does not name alternative tools (e.g., check_eligibility, get_country_tax) for actual determinations.

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