Slash Commands and Prompt Library

This guide describes the built-in slash commands, the LibreChat prompt library integration, and the FastMCP prompt templates.

Command Architecture

Built-In Slash Commands

When communicating with any tmux:* model in LibreChat, messages starting with a forward slash (/) trigger built-in daemon commands. The bridge intercepts these commands locally and executes them immediately without consuming language model tokens.

Process Control and Approvals

Command	Aliases	Function	Sent Keystroke
/approve	/y, /yes	Confirm interactive prompt or diff	y followed by Enter
/reject	/n, /no	Decline interactive prompt or diff	n followed by Enter
/cancel	/c, /sigint	Send interrupt signal	Ctrl+C (C-c)
/enter	/return	Send Enter keystroke	Enter
/esc	/escape	Exit mode or cancel dialog	Escape
/eof		Send End-of-File signal	Ctrl+D (C-d)

Terminal Inspection Commands

Command	Example	Function
/tail [n]	/tail 30	Display the latest n lines from the current session pane
/peek <session> [n]	/peek remote 20	Inspect terminal output from another session without switching models
/status	/status	Show daemon health, active session counts, and poll intervals

Session Management Commands

Command	Example	Function	Default Execution
/new [name] [dir] [preset|cmd]	/new dev /containers	Create a detached tmux session	Starts an interactive shell if no command is specified
/new <name> [dir] agy	/new run1 /containers agy	Start a session with Antigravity	Runs agy --dangerously-skip-permissions
/new <name> [dir] opencode	/new run2 /containers opencode	Start a session with OpenCode	Runs opencode --dangerously-skip-permissions
/agy [name] [dir] [args]	/agy work /containers	Launch an Antigravity agent	Runs agy --dangerously-skip-permissions [args]
/opencode [name] [dir] [args]	/opencode dev /containers	Launch an OpenCode agent	Runs opencode --dangerously-skip-permissions [args]
/kill <name>	/kill agent-run	Terminate the specified tmux session	Terminate target session
/list	/list	Show active sessions, window counts, and attach status	Return markdown table
/up	/up	Send Up arrow key and Enter	Re-run last shell command
/down	/down	Send Down arrow key	Navigate command history
/keys <combo> [session]	/keys C-z infra	Send arbitrary key sequence	Send raw tmux keys
/clear	/clear	Clear terminal scrollback buffer	Execute clear command
/help	/help	Show command reference table	Return reference text

LibreChat Prompt Library Integration

LibreChat includes a Prompt Library feature accessible from the chat interface. You can seed the LibreChat database to enable autocomplete suggestions when typing / in the message input field.

Seed Database Prompts

Execute the database seeding script from the repository root:

# Insert the 15 interactive command templates into MongoDB
python3 scripts/seed_librechat_prompts.py

# Remove previously seeded commands
python3 scripts/seed_librechat_prompts.py --clean

The script configures three database collections:

• promptgroups: Defines command names and descriptions.
• prompts: Specifies command templates and variable placeholders (for example, /peek 25).
• aclentries: Sets access control permissions for all authorized users.

FastMCP Prompts for Autonomous Supervision

When using an external reasoning model in LibreChat, you can activate predefined MCP prompts to supervise background CLI agents:

MCP Prompt	Purpose	Arguments
tmux_launch_agent	Launch an agent process (agy or opencode) with bypass permissions	agent_type, session_name, start_dir, task_goal
tmux_supervise_agent	Monitor an agent session, detect confirmation prompts, and summarize progress	session_name, task_goal
tmux_quick_approve	Inspect pending confirmation in a target session and send approval	session_name
tmux_status_summary	Query all active tmux sessions and generate a status report	None
