Quick Start

Launch Interactive Session

Command-Line Options

Options:

• --yolo - Skip permission prompts (safe mode is on by default)
• --model <model_name> - Specify model (e.g., claude-sonnet-4-20250514, gpt-4o)
• --tools <tool_list> - Filter available tools (comma-separated, or "" for none)
• --no-mcp - Disable MCP server integration
• --verbose - Enable verbose logging
• --theme <theme_name> - Set UI theme

Environment Variables:

• RIPPERDOC_ENABLE_TASKS=false - Use legacy Todo tools instead of Task Graph
• RIPPERDOC_TASK_LIST_ID - Force a shared Task Graph list ID across sessions
• RIPPERDOC_MODEL - Default model to use
• RIPPERDOC_TEMPERATURE - Default temperature (0.0-2.0)
• RIPPERDOC_API_KEY - API key for configured provider
• RIPPERDOC_CONFIG_DIR - Override where user-level Ripperdoc config/data are stored
• RIPPERDOC_AUTOCOMPACT_PCT_OVERRIDE - Override auto-compaction trigger percentage (1-100, capped at default threshold)
• RIPPERDOC_TMPDIR - Override internal temp root; Ripperdoc uses <this-path>/ripperdoc/
• RIPPERDOC_EXIT_AFTER_STOP_DELAY - In stdio/SDK mode, auto-exit after this many milliseconds of runtime idleness (positive integer only)
• RIPPERDOC_REMOTE_CONTROL_BASE_URL - Remote Control control-plane base URL (used by ripperdoc remote-control)
• RIPPERDOC_REMOTE_CONTROL_ACCESS_TOKEN - Bearer token for Remote Control control-plane API
• RIPPERDOC_REMOTE_CONTROL_INGRESS_URL - Optional override for session-ingress host (defaults to base URL)
• ENABLE_TOOL_SEARCH - Controls deferred MCP tool search mode: auto (default, on at 10% context), auto:N, true, false

Task Graph scope behavior:

• By default, task lists are session-scoped (new session starts clean; resume/continue keeps the same tasks)
• Set RIPPERDOC_TASK_LIST_ID to intentionally share one task list across sessions

Remote Control Bridge

Run a local bridge process that accepts remote work and spawns ripperdoc --sdk-url sessions:

export RIPPERDOC_REMOTE_CONTROL_BASE_URL="https://your-remote-control-host"
export RIPPERDOC_REMOTE_CONTROL_ACCESS_TOKEN="your-access-token"
ripperdoc remote-control

Basic Usage Examples
