Hnb Exchange Rates

hnb_exchange_rates
Read-onlyIdempotent

HNB (Croatian National Bank) official exchange rates for ALL foreign currencies on a given date. Croatia is in the eurozone, so every rate is quoted AGAINST THE EURO (units of foreign currency per 1 EUR). Returns rows with valuta (3-letter ISO code), srednji_tecaj (middle/reference rate), kupovni_tecaj (buying), prodajni_tecaj (selling), datum_primjene (apply date). Omit date for the latest applicable rates. Rate values are strings with a COMMA decimal separator (e.g. "1,164900").

A4.7/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, covering safety. Description adds meaningful context: rates quoted against EUR, return fields (valuta, rates, apply date), and comma decimal separator. No contradictions.

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, front-loaded with purpose and key details. Every sentence earns its place: first introduces the tool, second details quotation and return format. No filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given single optional parameter, no output schema, and full annotations, the description provides all necessary context: what the tool returns, how the data is expressed, and how to use the parameter. Complete for its complexity.

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 clear schema description for the optional 'date' parameter. Description adds value by stating 'Omit for the latest applicable rates' and specifying the format 'YYYY-MM-DD' (already in schema but reinforced). Exceeds baseline 3.

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 'official exchange rates for ALL foreign currencies on a given date', differentiating from the sibling 'hnb_currency_rate' (likely for a single currency). It specifies the resource (HNB exchange rates) and the scope (all currencies, date-driven).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly explains when to use: provides a date for a specific day or omit for latest rates. Implicitly contrasts with sibling tool 'hnb_currency_rate' which presumably handles single currencies. No ambiguity about usage context.

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

A3.7/5.0
Disambiguation2/5

Several tools have overlapping purposes: ask_pipeworx, ask_pipeworx_beta, and ask_pipeworx_grounded are near-identical (beta is currently identical to ask_pipeworx), and deep_research and validate_claim also overlap with the ask_pipeworx family. The Polymarket tools are more distinct, but the query family creates real ambiguity.

Naming Consistency2/5

Tool names mix leading verbs (ask_, compare_, resolve_, scan_) with leading nouns (entity_profile, recent_changes, hnb_currency_rate) and there are multiple subfamily prefixes (ask_pipeworx_*, polymarket_*, hnb_*). All are snake_case, but no consistent verb_noun or noun pattern is followed.

Tool Count2/5

33 tools is well above the 25+ threshold, and the server name ('Hnb Hr') implies a narrow Croatian banking scope while the majority of tools are for a broad data research platform. Many meta-tools (discover_tools, suggest_questions, pipeworx_feedback, pipeworx_trending) inflate the count beyond what the apparent purpose needs.

Completeness3/5

The HNB currency functionality is complete (single and all rates, historical and latest), and the broader data platform offers good coverage via the ask_pipeworx router, subscriptions, and memory tools. However, there are gaps (no direct HNB news or historical archive tool, patents soft-fail, and out-of-domain tools like generate_llms_txt), and the mismatch between server name and content leaves the surface feeling incomplete.
