A command for listing and closing numbered terminal panes, called slots, owned by the current session. A pane is a separate terminal area where a command or program may still be running.

Use it to list active slots, find a slot number after context is shortened, close one slot, or close every slot in the session.

It helps recover panes left open by other terminal commands and confirms that a selected pane or all panes have been closed.

slots — Command for Claude Code by MadAppGang/magus

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/MadAppGang/magus

Made for: Claude Code.

Or install terminal, the plugin that ships this one along with the rest of its 5 skills, 7 commands, 1 agent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00051	$0.00622
Opus 5.5	$0.00020	$0.00249
Sonnet 5.5	$0.00010	$0.00124
Haiku 4.5	$0.00005	$0.00062

Security

Grade A, and why

slots 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/terminal:slots

Advanced command — /terminal:run and /terminal:repl close their own slots. Use this command to see what is still open and to close what /terminal:watch and /terminal:tui leave running.

A slot is a numbered pane (1 to 64) the server places and owns. Slot 1 is the visible helper beside the user; higher slots may be visible or isolated. This command is a front for list-slots and close-pane.

Usage

/terminal:slots
/terminal:slots list
/terminal:slots close {N}
/terminal:slots close all

Subcommands

list — show every slot this session holds

mcp__plugin_terminal_mux__list-slots()
→ [{ "slot": 2, "isolated": true, "origin": "created", "foregroundCmd": "Python", "isAlive": true }]

An empty array means nothing is open:

→ []

Use it to recover a slot number after context compaction, to pick a free number before isolated: true, and to confirm a close succeeded.

close N — close one slot

mcp__plugin_terminal_mux__close-pane({ slot: 2 })
→ [{ "slot": 2, "action": "killed" }]

Closing interrupts whatever runs in the pane; no exit command is needed first. close-pane closes whichever kind of pane the slot holds and does not accept isolated.

close all — close every slot

mcp__plugin_terminal_mux__close-pane({ slot: "all" })
→ [{ "slot": 1, "action": "killed" }, { "slot": 2, "action": "killed" }]

Closes visible and isolated slots alike. Useful after a long workflow.

Examples

/terminal:slots              What is still open?
/terminal:slots close 1      Stop the dev server running in slot 1
/terminal:slots close all    Clean up everything

Notes

Slots live in the server, not in context: they survive compaction, and list is how you find them again.
A slot's kind (visible or isolated) is fixed when it is opened; to change it, close the slot and reopen it.
Slots are never the user's own pane. There is nothing here that lists or closes the user's tmux sessions.

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.

slots is a command published in the GitHub repository MadAppGang/magus (13 stars, last pushed yesterday), licensed MIT. It adds 51 tokens to every session and 622 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-08.
