close

A command for closing a tmux window linked to a worktree. A worktree is a separate working directory for a Git branch, while tmux manages terminal sessions and windows.

In plain words
What is it for?
Use it to close the current worktree's window or one named worktree, then reopen it later with the corresponding open command.
Why use it?
It removes a terminal window from view without deleting the worktree or branch, so unfinished work remains available.

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

close 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 2d 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.

What it actually says

Closes the tmux window for a worktree without removing the worktree or branch. This is useful when you want to temporarily close a window to reduce clutter or free resources, but plan to return to the work later.

workmux close [name]

Arguments

  • [name]: Optional worktree name (the directory name). Defaults to current directory if omitted.

Examples

# Close the window for a specific worktree
workmux close user-auth

# Close the current worktree's window (run from within the worktree)
workmux close

To reopen the window later, use workmux open.

:::tip You can also use tmux's native kill-window command (default: prefix + &) to close a worktree's window with the same effect. For worktrees created with --session, this closes the entire session. :::

Changes

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.
