Getting Started

pnpm install

Credentials Configuration

The Agent reads credentials from JSON5 files (no .env required).

Create empty templates:

multica credentials init

This creates:

• ~/.super-multica/credentials.json5 — core config (LLM providers + built-in tools)
• ~/.super-multica/skills.env.json5 — dynamic keys (skills / plugins / integrations)

Example credentials.json5 (OpenAI):

{
  version: 1,
  llm: {
    provider: "openai",
    providers: {
      openai: {
        apiKey: "sk-xxx",
        baseUrl: "https://api.openai.com/v1",
        model: "gpt-4o"
      }
    }
  },
  tools: {
    brave: { apiKey: "brv-..." }
  }
}

Example skills.env.json5 (dynamic keys):

{
  env: {
    LINEAR_API_KEY: "lin-...",
    SLACK_BOT_TOKEN: "xoxb-..."
  }
}

Start services directly (no source .env):

multica dev           # Start desktop app
multica run "hello"   # Run CLI mode

Optional overrides:

• SMC_CREDENTIALS_PATH — custom path for credentials.json5
• SMC_SKILLS_ENV_PATH — custom path for skills.env.json5

LLM Providers

Super Multica supports multiple LLM providers with two authentication methods:

OAuth Providers (use external CLI login):

• claude-code — Claude Code OAuth (requires claude login)
• openai-codex — OpenAI Codex OAuth (requires codex login)

API Key Providers (configure in credentials.json5):

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

Check Provider Status

# In interactive mode
/provider

# Output shows all providers with status
🔌 Provider Status

Current: kimi-coding

Available Providers:
  ID               Name                 Auth         Status
  ──────────────────────────────────────────────────────────────────────
  ✓ claude-code    Claude Code (OAuth)  OAuth        ready
  ✗ openai-codex   Codex (OAuth)        OAuth        not logged in
  ✓ kimi-coding    Kimi Code            API Key      configured (current)
  ...

Using OAuth Providers

# 1. Install and login to Claude Code
npm install -g @anthropic-ai/claude-code
claude login

# 2. Start multica with claude-code provider
multica --provider claude-code

Using API Key Providers

Add your API key to ~/.super-multica/credentials.json5:

{
  llm: {
    provider: "openai",
    providers: {
      openai: { apiKey: "sk-xxx" }
    }
  }
}

Configuration Priority

Each setting is resolved in order (first match wins):

1. CLI argument — --provider, --model, --api-key, --base-url
2. Credentials file — credentials.json5 (llm.provider + llm.providers[provider])
3. Session metadata — restored from previous session
4. Default — kimi-coding provider with kimi-k2-thinking model

Multica CLI

The unified CLI provides access to all agent features through a single command.

# Interactive mode (default)
multica
multica chat
multica chat --profile my-agent

# Run a single prompt
multica run "hello"
multica run --session demo "remember my name is Alice"

# Session management
multica session list
multica session show abc12345
multica session delete abc12345

# Continue a session
multica --session abc12345
multica run --session abc12345 "what did I say?"

# Override provider/model
multica run --provider openai --model gpt-4o-mini "hi"

# Use an agent profile
multica chat --profile my-agent

# Set thinking level
multica run --thinking high "solve this complex problem"

# Development servers
multica dev                # Start desktop app (default)
multica dev gateway        # Gateway only (:3000) - for remote clients
multica dev web            # Web app only (:3001)
multica dev all            # Start gateway + web

# Help
multica help
multica run --help
multica session --help

Short alias: mu (same as multica)

Sessions

Sessions persist conversation history to ~/.super-multica/sessions/<id>/. Each session includes:

• session.jsonl - Message history in JSONL format
• meta.json - Session metadata (provider, model, thinking level)

Sessions use UUIDv7 for IDs by default, providing time-ordered unique identifiers.

Context Window Management

The agent automatically manages context windows to prevent token overflow:

• Token-aware compaction - Tracks token usage and compacts when approaching limits
• Compaction modes: tokens (default), count (legacy), summary (LLM-generated)
• Configurable safety margins - Ensures space for responses
• Minimum message preservation - Keeps recent context intact

Agent Profiles

Agent profiles define identity, personality, tools, and memory for an agent. Profiles are stored as markdown files in ~/.super-multica/agent-profiles/<id>/.

Profile CLI

# Create a new profile with default templates
multica profile new my-agent

# List all profiles
multica profile list

# Show profile contents
multica profile show my-agent

# Open profile directory in file manager
multica profile edit my-agent

# Delete a profile
multica profile delete my-agent

Profile Structure

Each profile contains:

• identity.md - Agent name and role
• soul.md - Personality and behavioral constraints
• tools.md - Tool usage instructions
• memory.md - Persistent knowledge
• bootstrap.md - Initial conversation context

Skills

Skills are modular capabilities that extend agent functionality through SKILL.md definition files. For complete documentation, see Skills System Documentation.

Key Features

• Two-source loading - Global skills (~/.super-multica/skills/) and profile-specific skills
• GitHub installation - pnpm skills:cli add owner/repo to install from GitHub
• Slash command invocation - /skill-name args in interactive mode
• Eligibility filtering - Auto-filter by platform, binaries, and environment
• Hot reload - File watcher for development

Quick Start

# List all skills
multica skills list

# Install skills from GitHub
multica skills add anthropics/skills

# Check skill status with diagnostics
multica skills status
multica skills status pdf -v

# Install skill dependencies
multica skills install nano-pdf

# Remove installed skills
multica skills remove skills

Built-in Skills

Located in /skills/:

• commit - Git commit helper following conventional commits
• code-review - Code review assistance
• skill-creator - Create and manage custom skills (meta-skill for self-extension)

Creating Custom Skills

The agent can create new skills to extend its own capabilities. Simply ask the agent to create a skill:

User: Create a skill that helps me format JSON
Agent: [Creates ~/.super-multica/skills/json-formatter/SKILL.md]

Skills are automatically loaded via hot-reload. See the skill-creator SKILL.md for the complete guide.

Agent Tools

exec

Execute short-lived shell commands and return output. Commands running longer than the timeout are automatically backgrounded.

exec({ command: "ls -la", cwd: "/path/to/dir", timeoutMs: 30000 })

process

Manage long-running background processes (servers, watchers, daemons). Output is buffered (up to 64KB) and terminated processes are automatically cleaned up after 1 hour.

# Start a background process (returns immediately with process ID)
process({ action: "start", command: "npm run dev" })

# Check process status
process({ action: "status", id: "<process-id>" })

# Read process output
process({ action: "output", id: "<process-id>" })

# Stop a process
process({ action: "stop", id: "<process-id>" })

# Clean up terminated processes
process({ action: "cleanup" })

glob

Pattern-based file discovery using fast-glob.

glob({ pattern: "**/*.ts", cwd: "/path/to/dir" })

web_fetch

Fetch and extract content from URLs with intelligent content extraction.

# Basic fetch (returns markdown)
web_fetch({ url: "https://example.com" })

# With options
web_fetch({
  url: "https://example.com",
  outputFormat: "markdown",  # or "text"
  extractor: "readability"   # or "turndown" for full page
})

Features: SSRF protection, response caching, max 50KB output.

web_search

Search the web using Brave or Perplexity AI.

# Basic search
web_search({ query: "typescript best practices" })

# With provider options
web_search({
  query: "latest AI news",
  provider: "brave",     # or "perplexity"
  count: 5,
  freshness: "pw"        # past week (Brave: pd/pw/pm/py)
})

Architecture

Desktop App (Recommended)

The Electron desktop app runs a standalone Hub with embedded Agent Engine:

• No Gateway required for local development
• Direct IPC communication for optimal performance
• QR code pairing for mobile remote access
• Optional Gateway connection for web/remote clients

Gateway

The WebSocket gateway enables remote client access:

• Real-time message routing between clients and Hub
• Streaming support for long-running operations
• RPC-style request/response patterns
• Device verification and authentication

Hub

The Hub manages agents and communication:

• Agent lifecycle management
• Multi-subscriber event distribution
• Device whitelist and token-based verification
