systemprompt-sync

Cloud sync services for systemprompt.io AI governance infrastructure. Provides file, database, and crate deployment synchronization across governance tenants — bidirectional sync between local and cloud environments.

Layer: App — orchestrates domain modules. Part of the systemprompt-core workspace.

Overview

Part of the App layer in the systemprompt.io architecture. Infrastructure · Self-Hosted Deployment

This crate provides bidirectional sync capabilities for:

• File Sync - Upload/download service configuration files (agents, skills, content, config) as gzipped tarballs
• Database Sync - Export/import contexts between local and cloud Postgres databases
• Local Sync - Synchronise content and access-control rules between disk and the local database
• Crate Deploy - Build and deploy Docker images to Fly.io
• Scheduled Jobs - Background sync jobs registered with the systemprompt scheduler

Module Details

Sync Directions

Local disk-database sync uses LocalSyncDirection (ToDisk, ToDatabase) on LocalSyncResult.

Operation State

SyncService::sync_all returns per-operation results with a SyncOpState:

Usage

[dependencies]
systemprompt-sync = "0.11.0"

use systemprompt_sync::{SyncConfig, SyncService, SyncDirection};

let config = SyncConfig::builder(
    "tenant-id",
    "https://api.systemprompt.io",
    "api-token",
    "./services",
)
.with_direction(SyncDirection::Push)
.with_dry_run(false)
.build();

let service = SyncService::new(config);
let results = service.sync_all().await?;

Error Handling

The crate uses SyncError for all error conditions:

• MissingConfig - Required configuration (e.g., DATABASE_URL) not set
• ApiError - HTTP API failures with status code and message
• Database - SQL/connection errors
• Io - File system errors
• Unauthorized - Authentication required
• CommandFailed - Shell command execution failures
