List Published Packs or Geographies

get_catalog

Read-onlyIdempotent

Choose data or geometry to list published pack IDs or family and scope IDs. The response includes a complete catalog download URL. Use get_pack for data or get_geography for geometry. Current catalog: The same geography tools work worldwide across a cataloged baseline of 252 geographic entities, reaching up to Admin 2. Where additional country releases are available, the same calls automatically return deeper administrative tiers or maintained reference families. Additional detail is currently available for Australia, Brazil, Canada, France, Germany, Mexico, United Kingdom, United States.

TDQS

A3.5/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description's only behavioral addition is that the response carries a catalog download URL, which is already implied by the output schema; the long paragraph about worldwide coverage and per-country releases is scope marketing rather than behavioral disclosure.

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

Conciseness2/5

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

The actionable content (what it lists, the download URL, the get_pack/get_geography routing) is front-loaded, but it is then buried under a lengthy 'Current catalog' paragraph listing 252 entities and eight countries that does nothing for tool selection or invocation.

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

Completeness3/5

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

With annotations covering safety and an output schema covering returns, the description only needs to explain the selector and routing, which it mostly does. However, the undefined 'scope IDs' terminology and the routing to a non-sibling tool leave small gaps for an agent deciding between catalog and pack calls.

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% and the enum values are self-explanatory, so the baseline is 3. The description goes beyond this by mapping each enum value to a distinct return shape ('data' yields pack IDs, 'geometry' yields family and scope IDs), which genuinely adds meaning over the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

It names a specific verb ('list') and resource ('published pack IDs or family and scope IDs') and ties the output to the required catalog selector. It is distinguishable from the generic get_data/get_pack siblings, though the phrase 'family and scope IDs' is jargon that is never defined.

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 explicit routing: 'Use get_pack for data or get_geography for geometry,' which tells the agent when to pick this tool over an alternative. The weakness is that get_geography is not among the listed siblings, so the routing target is ambiguous for the agent.

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