agent-deck

agent-deck is a skill for Claude Code, Codex from majiayu000/claude-skill-registry. It costs 113 tokens per session (1,544 once invoked), scanned A, original, MIT.

A terminal-based session manager for AI coding agents. A session is a running or saved conversation with an agent; the tool lets you control sessions and connect external MCP tools.

In plain words
What is it for?
Use it to start, stop, restart, fork, or inspect agent sessions, send them tasks, and attach or list MCP connections.
Why use it?
It removes the need to manage each agent conversation manually in separate terminal windows. It also provides commands for checking status, sending messages, and reading responses.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-deck scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Quick Start

# Launch TUI
agent-deck

# Create and start a session
agent-deck add -t "Project" -c claude /path/to/project
agent-deck session start "Project"

# Send message and get output
agent-deck session send "Project" "Analyze this codebase"
agent-deck session output "Project"

Essential Commands

Command Purpose
agent-deck Launch interactive TUI
agent-deck add -t "Name" -c claude /path Create session
agent-deck session start/stop/restart <name> Control session

agent-deck mcp list List available MCPs
agent-deck mcp attach <name> <mcp> Attach MCP (then restart)
agent-deck status Quick status summary

Status: running | waiting | idle | error

Sub-Agent Launch

Use when: User says "launch sub-agent", "create sub-agent", "spawn agent"

scripts/launch-subagent.sh "Title" "Prompt" [--mcp name] [--wait]

The script auto-detects current session/profile and creates a child session.

Retrieval Modes

Mode Command Use When
Fire & forget (no --wait) Default. Tell user: "Ask me to check when ready"
On-demand agent-deck session output "Title" User asks to check
Blocking --wait flag Need immediate result

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
