# fbi_cde_state_reporting_coverage

Inspect monthly FBI UCR population coverage for one state in LiveDataLink's self-hosted CDE aggregate snapshot before interpreting its summarized crime trend. Returns reporting population, full population, coverage percentage, an explicit warning below 90 percent, pagination, and provenance. Use this for 'was California's 2021 FBI reporting coverage complete?', 'find low-coverage months in this state period', or to qualify an analysis. Coverage is not data quality proof and must accompany, not replace, methodological review.

## Why fbi_cde_state_reporting_coverage is rated Low

Even though fbi_cde_state_reporting_coverage only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

AI agents call fbi_cde_state_reporting_coverage to retrieve information from Livedatalink without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
