hubvibe_opendata_search
Read-onlyIdempotent

Government open data search across 16 national portals in one call: Korea (data.go.kr), Japan, Hong Kong, Australia, UK, Canada, the EU catalog (139,000+ datasets), Germany, Italy, Ireland, Switzerland, Netherlands, Israel and Chile. Query in any language; each match returns organization, update time and download URLs ready for opendata.table. Portals that did not answer are listed. Input: query; optional region, limit, portals. $0.10 per call. Returns: query, region, portals_searched[], portals_ok[], portals_failed[], total_matches{}, results[{portal, title, description, organization, landing_url, resources[{url, format}]...}], result_count, checked_at.

A4/5.0
Behavior4/5

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

Annotations already cover readOnly, idempotent, non-destructive, open-world semantics, so the bar is lower, and the description adds genuinely useful behavior: fixed pricing ($0.10/call), concurrent execution across portals, per-match metadata (organization, update time, download URLs), partial-failure reporting (portals_failed listed), and downstream readiness for opendata.table. It stops short of stating rate limits or timeout behavior for failed portals.

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

Conciseness3/5

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

Front-loaded with scope and portal list, which is good, but the long enumeration of 16 countries and the fully expanded return-shape inventory add bulk. The return-shape listing in particular is largely redundant with the declared output schema, making the description longer than it needs to be.

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 an output schema already exists, the description need not enumerate every return field, yet it does so anyway. It does cover the important behavioral gaps: cost, concurrency, partial-failure handling, and downstream use. Missing timeouts/rate-limits details, but otherwise complete for a read-only multi-source search tool.

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%, so the schema already documents all five parameters, including the BCP-47 language tag and enum values for region. The description only restates the parameter names (query; optional region, limit, portals) and adds no semantics beyond the schema baseline.

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 the exact verb and resource (search government open-data portals for datasets) and enumerates the 16 portals by name, including the EU catalog's size. The agent can tell this apart from sibling hubvibe_opendata_table (which consumes results) and hubvibe_search_web without opening a schema.

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 makes the multi-portal scope explicit and notes queries can be in any language, but it does not state when to prefer this over hubvibe_search_web, hubvibe_data_query, or hubvibe_research_web for government-dataset lookups. No explicit exclusion or alternative routing is provided.

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