create

A command that creates a new Git branch and a separate worktree at the same time. A worktree is an independent directory where you can develop on that branch without changing your current directory.

In plain words
What is it for?
Use it to create worktrees from branch names or issue numbers, optionally prepare a Claude workspace, and open the result in tmux panes.
Why use it?
It makes parallel work easier by giving each feature or issue its own working environment. You avoid repeatedly switching the main checkout between branches.

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

create 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 yesterday.

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.

# Create with tmux session (prompts for attachment in TTY, auto-attaches in non-TTY)
mst create feature/new-feature --tmux

# Create with tmux session and set up Claude workspace
mst create feature/new-feature --tmux --claude-md

# Create with tmux pane split options (when already in tmux)
mst create feature/new-feature --tmux-h  # Horizontal split
mst create feature/new-feature --tmux-v  # Vertical split

# Create with multiple tmux panes
mst create feature/api --tmux-h-panes 3       # 3 horizontal panes

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.
