openlatch-client-schemas
Canonical JSON Schemas for the openlatch-client wire format. This package is the source of truth for the contract between openlatch-client (Rust) and openlatch-platform (Python + React).
OpenLatch is the agent-agnostic execution control layer for enterprise AI agents. The client is its capture-and-enforce adapter, running inside the agent's execution path; the platform authors the policy it evaluates. These schemas are what the two exchange.
Usage
from openlatch_client_schemas import schemas_path, load, load_all, load_catalog
schemas_path() # pathlib.Path to the bundled schemas/ directory
load_all() # {"enums": {...}, "event-envelope": {...}, ...}
load("event-envelope") # parsed schema for one file
load_catalog() # retained protocol families, adapters and fixtures

Breaking Changes
Breaking schema changes require a major version bump. Consumers pinning an exact version will not be silently broken. See the openlatch-client CHANGELOG for what changed.
