get_public_holidays

FREE. Official public-holiday calendar for a supported country, including gazetted movable holidays, with the official government source cited. Some countries also carry sub-national calendars (e.g. the German Laender): the subdivisions field lists them, and passing subdivision (ISO 3166-2, e.g. 'DE-BY') returns the national calendar merged with that region's statutory days.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`country`	Yes	ISO country code
`subdivision`	No	Optional ISO 3166-2 region code (e.g. 'DE-BY'). Returns national + that region's statutory holidays, each tagged national/regional. Omit for the national calendar.

Behavior4/5

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

With no annotations, the description carries full burden. It discloses that the tool is free, cites official government sources, and details subdivision merging behavior. This adds value beyond the schema, though response format or rate limits are not mentioned.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no filler. First sentence fronts the main purpose, second sentence clarifies the subdivision feature. Efficient and well-structured.

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 a simple 2-parameter tool with no output schema, the description covers the essential behavior, supported countries, and subdivision logic. It omits return format but remains adequate for correct invocation.

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%, but the description adds meaning by explaining the subdivision parameter's effect (merging national and regional holidays) and the 'subdivisions' field. This goes beyond the enum descriptions.

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 clearly states the tool retrieves an official public holiday calendar for supported countries, including movable holidays and sub-national calendars. The verb 'get' combined with specific resource 'public holidays' and details about subdivisions distinguishes it from sibling financial tools.

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?

The description implies usage for retrieving public holidays but does not explicitly state when to use versus siblings. It provides context on subdivision behavior but lacks exclusion criteria or alternatives.

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

A4.2/5.0

Disambiguation5/5

Each tool targets a distinct operation (check, compute, count, get, list) and a distinct resource (minimum wage, income tax, VAT, working days, holidays, series, settlement). The series tools are clearly differentiated by granularity (list, current, history, snapshot), and compute/check tools apply calculations rather than just returning values.

Naming Consistency4/5

Most tools follow a consistent verb_noun pattern (check_, compute_, count_, get_, list_), but settlement_date is a noun phrase without a verb, and the verbs vary (check, compute, count, get, list) rather than using a single style. Still, the names are descriptive and predictable.

Tool Count5/5

10 tools is within the ideal 3-15 range, and each tool earns its place by covering a distinct facet of statutory reference data: taxes, compliance checks, calendars, series, and settlement. There is no bloat or sense of missing essential tools.

Completeness4/5

The surface provides strong coverage: compliance checks (minimum wage, taxes), calendar operations (holidays, working days), series catalog/current/history/snapshot, and settlement dates. Minor gaps include no direct tool for settlement conventions (mentioned only as an external endpoint) and no standalone tax bracket getter, but get_series likely covers some rates and users can infer brackets from compute_income_tax.
