# 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.

See [Memo](./docs/memo.md) for product vision, architecture, and roadmap.

## Getting Started

```bash
pnpm install
```

### Development

```bash
# 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:**

```bash
# 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

```bash
multica credentials init
```

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

Example `credentials.json5`:

```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

```bash
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>/`.

```bash
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](./src/agent/skills/README.md).

```bash
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](./src/agent/tools/README.md) 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.

```mermaid
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
