name: agent-deck description: agent-deck, the terminal session manager for AI coding agents. Use when the user mentions "agent-deck", "session", "sub-agent", "MCP attach", or "git worktree", or needs to create, start, message, read, fork, restart, or supervise agent-deck sessions; launch child sessions or consult another CLI through agent-deck; attach MCPs to a session; manage groups, profiles, accounts, or worktree sessions; set up conductors or watchers; configure config.toml; or troubleshoot agent-deck. Not for in-conversation subagents, plain git worktrees, or plain tmux. metadata: compatibility: "claude, codex, opencode"

Agent Deck

Run agent-deck --version for your installed version. This skill targets v1.16.11+; most patterns work back to v1.7. See Backward Compatibility for what needs ≥1.16.11.

Scripts

Helper scripts live in this skill's scripts/ folder. Resolve them from the base directory shown when the skill loaded, not from the user's project:

SKILL_DIR="/path/shown/in/base-directory-line"
$SKILL_DIR/scripts/launch-subagent.sh "Title" "Prompt" --wait

Plugin installs resolve to ~/.claude/plugins/cache/agent-deck/agent-deck/<hash>/skills/agent-deck/; a repo checkout resolves to <repo>/skills/agent-deck/.

Essential Commands

Command	Purpose
agent-deck	Launch interactive TUI
agent-deck add -t "Name" -c claude /path	Create session
agent-deck launch . -c claude --account <name>	Create and start a session under a named account slot
agent-deck session start/stop/restart <name>	Control session
agent-deck session send <name> "message"	Send message
agent-deck session send <name> --message-file <file>	Send message from file (- = stdin); no shell quoting. Also on launch/session start
agent-deck session output <name>	Get bounded, ANSI-clean last response (JSON/quiet/copy preserve full source)
agent-deck session children --json	Child sessions' live status + asserted completions (non-blocking, read-only)
agent-deck session current [-q|--json]	Auto-detect current session
agent-deck session fork <name>	Fork Claude/OpenCode/Pi/Codex/Oh My Pi conversation
agent-deck mcp list	List available MCPs
agent-deck mcp attach <name> <mcp>	Attach MCP (then restart)
agent-deck status	Quick status summary
agent-deck open report.html	Show an HTML report to the user in the macOS app Browser panel (works from remote sessions too)
agent-deck add --worktree <branch>	Create session in git worktree

Status: ● running | ◐ waiting | ○ idle | ✕ error

Every other command and flag is in cli-reference.md.

Rules

1. Flags before arguments: session start -m "Hello" name, not name -m "Hello". A flag that seems ignored is almost always in the wrong position.
2. MCPs on request only: attach one when the user asks, then session restart it; attaching alone does not load it. --global writes Claude's config for every project; the default writes the session's .mcp.json.
3. Leave other sessions to work: read another session with a single session output or session children call rather than a polling loop, which can interfere with the target.
4. State only the task in a child's prompt. Every session agent-deck launches already carries its identity (session id, title, parent, core commands, completion sentinel; $AGENTDECK_IDENTITY_FILE for custom --cmd), so a prompt need not explain who the child is or how to reach its parent. Opt out with --no-identity or [launch] inject_identity = false; gemini also needs its identity folder trusted (documentation/HARNESS_IDENTITY.md).

Configuration

$XDG_CONFIG_HOME/agent-deck/config.toml (default ~/.config/agent-deck/config.toml; legacy ~/.agent-deck/config.toml still honored). Every option is in config-reference.md.
