Multi-Agent Workflow Orchestration Engine. One Bus. Zero Friction.

Glink

Multi-Agent. One Bus. Zero Friction.

Glink is a lightweight orchestration engine that turns your AI agents into a collaborative assembly line. Define a workflow in YAML, and Glink routes each step to the right agent — passing context, handling failures, and logging every heartbeat onto a shared JSONL blackboard. No databases, no message queues, no external dependencies.

Quick Start

# Clone & go
cd glink

# Run a workflow (resumes from last checkpoint automatically)
python3 glink-daemon.py sandbox-builder

# Force restart from step 1
python3 glink-daemon.py sandbox-builder --force

# Jump to a specific step
python3 glink-daemon.py sandbox-builder --step 4

# Serve-only mode (API without running workflow)
python3 glink-daemon.py --serve

# Dashboard
open http://127.0.0.1:8426

Features

Feature	Description
YAML Workflows	Define steps, agents, dependencies, and fallbacks in one file
Main Bus	JSONL blackboard — append-only, agent-agnostic, replayable
Smart Routing	Primary agent down? Auto-fallback to the next in line
Checkpoint Resume	Crash mid-workflow? Restart picks up exactly where it left off
Dependency Graph	Steps can depends_on each other; Glink handles ordering
Retry Loop	Auto-retry failed steps (configurable, default 2×)
HTTP API + SSE	Live status, agent health, and event stream on :8426
Healthcheck Cron	Self-healing — daemon restarts on crash, alerts via Feishu
Zero Deps	One Python file + one JSONL file. No pip install needed
