# For agents: What is in the libraries

OpenProse today · board 7 of 17 · 2026-10-09.
This deck records dated experimental evidence, not general reliability.

Select shared definitions as needed across twenty published application libraries.

## On the slide

**Standard library**

**Twenty application libraries**

Examples: Math · Quant · Law · Manufacturing · Agent ecology

## Explanation

The standard library supplies shared requirements, including evidence, review, bounded work, result reporting, and the five families shown here. Application packages add specialist contracts and tests. The published OpenProse Ecology package concerns populations and interactions of agents and models. Application work also fed improvements back into shared definitions: quantity reconciliation serves multiple domains, as does retaining exact candidates for review. Each package is individually public and versioned. A library entry describes available work; selecting and adopting definitions determines which requirements apply to a particular job.
