Super Multica

Multiplexed Information & Computing Agent

An always-on AI agent that pulls real data, runs real computation, and takes real action — monitoring, analyzing, and acting within user-defined authorization boundaries.

Getting Started

pnpm install

Development

# Desktop app (recommended for local development)
pnpm dev

# Web app (for browser-based access)
pnpm dev:web         # Start Web app on :3000

# Gateway (for remote/mobile clients)
pnpm dev:gateway     # Start Gateway on :3000
pnpm dev:all         # Start both Gateway and Web app

The Desktop app runs a standalone Hub with embedded Agent Engine - no Gateway required for local use.

Environment Configuration

Desktop (apps/desktop/.env.*):

Variable	Description
MAIN_VITE_GATEWAY_URL	WebSocket Gateway URL for remote device pairing
MAIN_VITE_WEB_URL	Web app URL for OAuth login redirect

Web (apps/web/next.config.ts):

Variable	Description
API_URL	Backend API URL (default: https://api-dev.copilothub.ai)

Build for different environments:

# Desktop
pnpm --filter @multica/desktop build              # Production (.env.production)
pnpm --filter @multica/desktop build:staging      # Staging (.env.staging)

# Web (Vercel)
# Set API_URL in Vercel Dashboard → Settings → Environment Variables

See apps/desktop/.env.example and apps/web/.env.example for details.

Monorepo Development

Command	Purpose
pnpm dev	Full dev mode — watches core, types, utils packages
pnpm dev:desktop	Desktop only — skip package watching

When modifying packages:

1. Edit code in packages/core, packages/types, or packages/utils
2. Terminal shows [core] ESM ⚡️ Build success (~100ms)
3. Restart Desktop to apply changes (Ctrl+C, then pnpm dev)

Why restart? Electron main process does not support hot reload — this is an Electron limitation, not ours.

Credentials

multica credentials init

Creates:

• ~/.super-multica/credentials.json5 — LLM providers + tools
• ~/.super-multica/skills.env.json5 — skill/plugin API keys

Example credentials.json5:

{
  version: 1,
  llm: {
    provider: "openai",
    providers: {
      openai: { apiKey: "sk-xxx", model: "gpt-4o" }
    }
  },
  tools: {
    brave: { apiKey: "brv-..." }
  }
}

LLM Providers

OAuth Providers (external CLI login):

• claude-code — requires claude login
• openai-codex — requires codex login

API Key Providers (configure in credentials.json5):

• anthropic, openai, kimi-coding, google, groq, mistral, xai, openrouter

Check status: /provider in interactive mode

CLI

multica                              # Interactive mode
multica run "prompt"                 # Single prompt
multica chat --profile my-agent      # Use profile
multica --session abc123             # Continue session
multica session list                 # List sessions
multica profile list                 # List profiles
multica skills list                  # List skills
multica help                         # Show help

Short alias: mu

Sessions

Sessions persist to ~/.super-multica/sessions/<id>/ with JSONL message history and JSON metadata. Context windows are automatically managed with token-aware compaction.

Profiles

Profiles define agent identity, personality, and memory in ~/.super-multica/agent-profiles/<id>/.

multica profile new my-agent    # Create profile
multica profile list            # List all
multica profile edit my-agent   # Open in file manager

Profile files: soul.md, user.md, workspace.md, memory.md, memory/*.md

Skills

Skills extend agent functionality via SKILL.md files. See Skills Documentation.

multica skills list              # List skills
multica skills add owner/repo    # Install from GitHub
multica skills status            # Check status

Built-in: commit, code-review, skill-creator

Tools

Available tools: read, write, edit, glob, exec, process, web_fetch, web_search, memory_search, sessions_spawn

See Tools Documentation for details.

Architecture

Desktop App (standalone, recommended)
  └─ Hub (embedded)
     └─ Agent Engine

Web/Mobile Clients
  → Gateway (WebSocket, :3000)
    → Hub
      → Agent Engine

• Desktop App: Electron app with embedded Hub, no Gateway needed
• Gateway: WebSocket server for remote clients
• Hub: Agent lifecycle and event distribution

Time

Super Multica now uses message-level timestamp injection for time awareness. Instead of placing dynamic time text in the system prompt, user turns are stamped at runtime.

flowchart TD
  A[Incoming turn] --> B{Entry point}
  B -->|Desktop/Gateway/Cron/Subagent| C[AsyncAgent.write]
  B -->|Heartbeat poll| D[AsyncAgent.write injectTimestamp=false]
  C --> E{Already stamped or has 'Current time:'?}
  E -->|Yes| F[Keep original message]
  E -->|No| G[Prefix: [DOW YYYY-MM-DD HH:mm TZ]]
  D --> H[Keep original heartbeat prompt]
  F --> I[Agent.run]
  G --> I
  H --> I
  I --> J[LLM receives final turn text]

Injection Matrix

Path	Runtime call	Timestamp injected?	Notes
Desktop direct chat	agent.write(content)	Yes	Default behavior
Gateway/remote chat	agent.write(content)	Yes	Same entry path as desktop
sessions_spawn child task	childAgent.write(task)	Yes	Child turn gets current time context
Cron agent-turn payload	agent.write(cronMessage)	Yes (guarded)	Skips if message already carries Current time:
Heartbeat runner	agent.write(prompt, { injectTimestamp: false })	No	Prevents heartbeat prompt matching from breaking
Internal orchestration	writeInternal(...)	No	Uses separate internal run path

Why this design

• Keeps system prompt cache-stable (no per-turn date churn in system prompt text)
• Gives the model an explicit "now" reference on each user turn
• Uses guardrails to avoid double-stamping and heartbeat regressions
