Inspect Known loc_id Identities

get_loc_id_info

Read-onlyIdempotent

Fetch detailed place data for a known loc_id or bounded loc_ids array, including identity, parentage, lifecycle, shape status, and available data packs, with optional hierarchy and references.

Instructions

Known-place navigation and enrichment tool: use only when you already have one canonical loc_id or a bounded loc_ids array. It returns identity, strict stored parentage, lifecycle, shape status, and place-specific data-pack and geometry-family availability with executable next calls. It does not list the global catalog and does not return polygon coordinates; use get_catalog to browse everything or get_geometry for shapes. Set include_hierarchy for same-release ancestors and include_references for maintained external or cross-family connections. Historical records are never replaced automatically. No payment required.

Input Schema

TableJSON Schema

Name	Required	Description
`iso3`	No	Optional country hint for crosswalk artifacts. Defaults to the loc_id country when possible.
`loc_id`	No	DaedalMap loc_id, e.g. 'USA-CA'.
`loc_ids`	No	DaedalMap loc_ids to inspect together, including every loc_id from a resolve_point stack. Default public cap is deployment-configurable.
`systems`	No	Optional reference systems to include when include_references is true, such as zcta, nws_fire, overlay_tribal, or overlay_nws_public_zone.
`batch_id`	No	Optional caller-supplied batch id for tracing.
`min_share`	No	Optional minimum target-area share for reverse overlap references.
`request_id`	No	Optional caller-supplied request id for tracing.
`limit_per_system`	No	Maximum overlap references to return per bridge/system. Default 10.
`include_hierarchy`	No	When true, include strict stored parent and ancestor data. This never invents a parent edge across mixed releases. Default false.
`include_references`	No	When true, include known external or side-chain references attached to each loc_id. Default false.
`target_admin_level`	No	Admin level for crosswalk-backed reverse reference lookup. Inferred when omitted.

TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds valuable behavioral context beyond annotations: 'Historical records are never replaced automatically' and 'No payment required.' This enriches the agent's understanding of side effects and constraints.

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?

The description is compact given the tool's complexity. It front-loads the purpose, then scopes usage, then lists exclusions, then mentions key flags and behavioral caveats. Every sentence serves a distinct function, though the phrase 'executable next calls' is slightly vague and could be clearer.

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 an 11-parameter tool with an output schema and strong annotations, the description covers the return contents, usage conditions, exclusions, and important behavioral notes (historical record handling, payment). The only minor gap is the vague 'executable next calls,' but overall it is comprehensive enough for correct invocation.

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 fully documents all 11 parameters. The description only mentions include_hierarchy and include_references in passing, without adding semantics beyond the schema. Baseline 3 applies because the schema does the heavy lifting and the description adds minimal extra parameter guidance.

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 purpose: 'Known-place navigation and enrichment tool' and lists what it returns (identity, strict stored parentage, lifecycle, shape status, data-pack/geometry availability). Clearly distinguishes from siblings by noting it does not list the global catalog and does not return polygon coordinates, naming get_catalog and get_geometry as the appropriate alternatives.

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 sets the precondition: 'use only when you already have one canonical loc_id or a bounded loc_ids array.' Also provides when-not guidance ('does not list the global catalog') and names the alternatives (get_catalog, get_geometry). This is unambiguous usage direction.

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