List Published Packs or Geographies

get_catalog

Read-onlyIdempotent

List published data or geometry pack IDs and family or scope IDs, returning a complete catalog download URL for the selected catalog.

Instructions

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.

TDQS

A3.7/5.0

Behavior3/5

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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world behavior, so the safety profile is covered. The description adds that the response includes a complete catalog download URL, which is helpful context, but an output schema exists and no other behavioral detail (e.g., ordering, size) is given.

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?

Three short sentences with the core action front-loaded and no wasted wording. The final routing sentence is compact but reads slightly redundant with the first.

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?

With a single enum parameter, full schema coverage, an output schema, and rich annotations, the description covers everything an agent needs to select and invoke this tool correctly.

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 schema's own parameter description ('Required directory selector') is vague; the description compensates by explaining that 'data' yields pack IDs and 'geometry' yields family and scope IDs, adding real meaning about each enum value's output.

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?

The description states a concrete verb (list) and resource (published pack IDs or family/scope IDs) and names sibling tools (get_pack, get_geography) that serve adjacent needs. It is distinguishable from siblings, though the phrase 'family and scope IDs' is slightly opaque.

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

Usage Guidelines3/5

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

It tells the agent to choose 'data' vs 'geometry' and points to get_pack/get_geography, but the routing condition overlaps with the catalog selector, leaving it unclear when to stop at get_catalog versus escalate to a get_pack/get_geography call.

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