What it does
Rmux is an agent skill from Helvesec/rmux. Guide for using RMUX with Claude Code, including the tmux-compatible CLI, agent automation waits, the typed SDK, browser web-share, and the rmux claude launcher.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with tmux, Rust, Linux and macOS. The repository describes itself as: Universal Rust multiplexer with a typed SDK — drive any CLI or TUI app from code. Native on Linux, macOS, and Windows.
Example prompts
- “/rmux”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 1f4571e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
cargo
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Rmux loads about 1.3k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 490 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 490 words (~1,260 tokens).
“RMUX is a Rust terminal multiplexer with a tmux-compatible CLI, a typed SDK, browser web-share, and a Claude Code launcher. Prefer checking the installed binary instead of assuming a version:”
- name
- rmux
- disable-model-invocation
- true
