Agent-Core

Fork of sst/opencode — Built on OpenCode. All credit goes to the brilliant SST team and the OpenCode contributors for creating an exceptional open-source AI coding agent. This fork extends OpenCode with a specialized personas system, semantic memory, and multi-surface orchestration. Please use the upstream repository for official releases and support; use this fork at your own risk.

Agent-Core is a CLI agent engine that powers the Personas system (Zee, Stanley, Johny). Built on OpenCode's excellent foundation, it adds persona-based routing, semantic memory, and orchestration capabilities.

Quick Start

Prerequisites

• Bun (v1.1+)
• Qdrant (local or cloud) for semantic memory
• API key for Anthropic (Claude) or OpenAI

Installation

# Clone the repository
git clone https://github.com/yourusername/agent-core.git

# Install dependencies
cd agent-core
bun install

# Build the project
cd packages/agent-core
bun run build

# Install the binary (optional)
cp dist/agent-core-linux-x64/bin/agent-core ~/bin/agent-core

Configuration

1. Copy the environment template:

cp .env.example .env

2. Edit .env and add your API keys:

ANTHROPIC_API_KEY=sk-ant-...
OPENAI_API_KEY=sk-...  # For embeddings
QDRANT_URL=http://localhost:6333

3. Start Qdrant (if running locally):

docker run -p 6333:6333 qdrant/qdrant

Running

Interactive TUI:

agent-core

Daemon mode (for external gateways):

agent-core daemon --gateway --hostname 127.0.0.1 --port 3210

Personas

Persona	Domain	Description
Zee	Personal Assistant	Memory, messaging, calendar, notifications
Stanley	Investing	Markets, portfolio, trading strategies
Johny	Learning	Knowledge graphs, spaced repetition

Key Features

• Semantic Memory: Vector-based memory with Qdrant for context persistence
• Multi-Persona Routing: Route messages to specialized personas
• Orchestration: SPARC methodology via tiara for complex tasks
• External Gateway: HTTP API for messaging platform integration

Usage with Zee Gateway

The Zee Gateway handles messaging platforms (WhatsApp, Telegram, Discord, etc.) and routes to agent-core:

# Terminal 1: Start agent-core daemon
agent-core daemon --gateway

# Terminal 2: Start zee gateway
cd ~/Repositories/personas/zee
pnpm zee gateway

Messages mentioning @stanley or @johny are routed to those personas; all others go to Zee.

Development

# Run tests
bun test

# Build
bun run build

# Type check
bun run typecheck

Wide events

Agent-core emits wide event JSONL logs for per-request diagnostics:

agent-core logs wide --lines 50
agent-core logs wide --where sessionId=session_123
