Agent System

7 built-in agents optimized for specific tasks:

Agent	Specialization
code-review	Deep code analysis, security, and style checks
debug	Error diagnosis and root cause analysis
architect	System design and architecture planning
refactor	Code restructuring and improvement
test-writer	Test generation and coverage analysis
docs	Documentation generation
security	Security vulnerability scanning

Usage

/agent start code-review    # Start an agent
/agent list                  # View all available agents
/agent status                # Check running agent status
/agent stop                  # Stop current agent

Agents run through the SDK using native AgentDefinition support with tailored system prompts.

MCP Server Management

Manage Model Context Protocol servers for Claude:

/mcp list        # Show configured MCP servers
/mcp add         # Add a new MCP server
/mcp remove      # Remove an MCP server
/mcp status      # Check connection status
/mcp test        # Test a server connection
/mcp toggle      # Enable/disable a server mid-session
/mcp reconnect   # Reconnect a failed server mid-session

MCP configuration is stored in .claude/mcp.json:

{
  "mcpServers": {
    "my-server": {
      "command": "npx",
      "args": ["-y", "my-mcp-server"],
      "env": {
        "API_KEY": "your-key"
      }
    }
  }
}

Mid-Session Controls

Change model or permissions without restarting your session:

/claude-control set-model claude-sonnet-4-20250514
/claude-control set-permissions bypassPermissions
/claude-control stop-task <task_id>
/claude-control status
/claude-control interrupt

These operations apply immediately to the active query.

File Rewind

Undo file changes made during a Claude session:

/rewind turn:3              # Rewind to turn 3
/rewind turn:5 dry_run:true # Preview what would change

Requires file checkpointing to be enabled via /settings.

Structured Output

Force Claude to respond in JSON matching a specific schema:

1. Enable via /settings > output > toggle-structured-output
2. Set schema via /settings > output > set-output-schema

Example schema:

{
  "type": "object",
  "properties": {
    "summary": { "type": "string" },
    "confidence": { "type": "number" }
  }
}

When enabled, responses follow json_schema output format through the SDK.

Thread-per-Session

Keep conversations organized with dedicated Discord threads:

• /claude-thread — Start a new Claude session in its own thread
  • name — Custom thread title (required)
  • prompt — Your initial prompt (required)
• Per-channel session tracking — Regular /claude commands in the same channel automatically reuse the last session (no need to pass session_id)
• Thread auto-naming — Threads are named with your custom title or a truncated version of the prompt
• Seamless continuation — Subsequent /claude commands inside a session thread continue that conversation

How It Works

1. Run /claude-thread name:"Fix auth bug" prompt:"Review the auth module"
2. A new thread titled Fix auth bug is created
3. Claude's response streams into the thread
4. Any further /claude commands in that thread continue the same session
5. Use /claude-thread again in the main channel to start a fresh conversation in a new thread

Channel Monitoring

Automatically investigate alerts from other bots or webhooks:

1. A monitored bot posts in the configured channel
2. Messages are batched over a 30-second debounce window
3. A thread is created on the alert message
4. Claude analyzes the alert and streams its investigation into the thread

Setup

MONITOR_CHANNEL_ID=123456789012345678    # Channel to watch
MONITOR_BOT_IDS=987654321,111111111      # Bot/webhook user IDs to respond to

Requires the Message Content privileged intent enabled in the Discord Developer Portal. The bot needs Read Messages, Create Public Threads, and Send Messages in Threads permissions in the monitored channel.

Role-Based Access Control (RBAC)

Restrict dangerous commands to authorized users and roles:

Restricted Command Categories

Category	Commands
Shell	/shell, /exec, /run, /terminal
Git	/git, /commit, /push, /pull, /branch
System	/shutdown, /restart, /config
Admin	/admin

Configuration

Set via environment variables in .env:

# Comma-separated Discord Role IDs
ADMIN_ROLE_IDS=123456789,987654321

# Comma-separated Discord User IDs (bypass role checks)
ADMIN_USER_IDS=111111111,222222222

Behavior

• Neither variable set: RBAC disabled — all commands open (default)
• One or both set: Only users with a listed role or user ID can run restricted commands
• Denied users: Receive an ephemeral "Permission Denied" message (only they can see it)
• Unrestricted commands: Always available to everyone (e.g., /claude, /settings, /help)
