Mirabello Immigration Intelligence

Citation-First Provenance

get_provenance

Read-onlyIdempotent

CITATION-FIRST provenance for a country's pathway facts (W3C PROV-O + Schema.org). For each fact returns: the cited official source_url + source_class + verbatim quote (evidence), how it was derived (extraction model + ensemble + independent corroboration), confidence, first_seen/last_changed, and a per-data-class FRESHNESS block (as_of, governing_class, sla_days, status fresh|aging|stale|CHECK-OFFICIAL-SOURCE, recheck_by). Use this to CITE Mirabello data with a source + as-of date and to know when to re-verify. Pass cc (+ optional pathway).

TDQS

A4.1/5.0

Behavior4/5

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

The annotations already declare readOnly, idempotent, non-destructive, and closed-world behavior. The description adds valuable behavioral context beyond that: each fact carries a verbatim quote, derivation details, independent corroboration, and freshness statuses including CHECK-OFFICIAL-SOURCE and recheck_by. Much of the return-shape detail overlaps with the output schema, so it is not a full 5.

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 dense but front-loads the CITATION-FIRST concept and then summarizes returns and usage in a single focused paragraph. It could be easier to scan with structure, but every sentence carries relevant information.

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 that an output schema exists and schema coverage is complete, the description provides enough context for an agent to call the tool correctly and understand its citation/freshness purpose. It leaves minor gaps, such as how pathway ids are discovered or what happens when no provenance is available, but those are not required for a correct invocation.

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 description coverage is 100% and both parameters are already documented in the input schema. The description only says 'Pass cc (+ optional pathway),' adding no syntax, constraints, or meaning beyond the schema, so the baseline of 3 applies.

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 resource and mode: CITATION-FIRST provenance for a country's pathway facts, with W3C PROV-O and Schema.org framing. It makes clear this is not a general country-fact tool but a citation/evidence layer, which distinguishes it from siblings like get_country or get_recent_changes.

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 explicitly says to use this when citing Mirabello data with a source and as-of date, and when deciding if re-verification is needed. It does not name a sibling alternative or state when not to use it, so it falls short of the highest tier but gives clear usage context.

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