Get Data

get_data

Read-onlyIdempotent

Retrieve rows from one selected published data pack using exact metrics, loc_id-based region filters, time/metric filters, sorting, and a row limit. Disaster event rows include stable event_id values for get_event drill-down. A parent administrative loc_id selects matching descendant rows at the pack's published grain. Call get_pack first; geometry families use their focused next-step tools.

Input Schema

Name	Required	Description
`sort`	No	Sort by a sortable field from get_pack; direction defaults to asc.
`limit`	No	Maximum number of rows to return for the requested source or pack.
`output`	No	Optional response controls. v1 supports rows only.
`filters`	Yes
`metrics`	Yes	Exact metric ids from get_pack. Use event_count for aggregate counts only when get_pack publishes it.

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds genuinely non-obvious behavior beyond that: a parent administrative loc_id expands to descendant rows at the pack's published grain, and disaster rows carry stable event_id values. It does not discuss the 500-row cap implications, pagination, or truncation behavior.

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?

Four sentences, front-loaded with the core action before prerequisites and edge-case semantics. The opening enumeration of metrics/filters/sorting/limit slightly duplicates schema content, but the remainder (descendant expansion, event_id stability, prerequisite call) is all load-bearing.

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?

For a seven-parameter, deeply nested query tool with an output schema, this covers the pieces an agent cannot infer: the prerequisite chain via get_pack, hierarchical loc_id behavior, and where to go next for events. Return shape is handled by the output schema, so the remaining gap is minor — mainly what happens near the row limit.

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 high (86%), so the baseline is 3, but the description earns more: it clarifies that metric ids must be exact and published by get_pack, that region filters are loc_id-based with hierarchical expansion semantics, and that event_count is a conditional aggregate metric. Sorting and limit are named but not elaborated beyond the schema.

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 a specific verb and resource ("Retrieve rows from one selected published data pack") and immediately scopes it: exact metrics, loc_id region filters, time/metric filters, sorting, row limit. It distinguishes itself from siblings by naming get_pack as the prerequisite and get_event as the drill-down follow-up, so an agent can place it in the workflow 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?

Gives an explicit prerequisite ("Call get_pack first") and a partial exclusion ("geometry families use their focused next-step tools"), which is exactly the routing information needed. It stops short of naming those geometry tools or defining when to prefer a different row source, so it is strong but not exhaustive.

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