Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned johnlindquist/claude at eb37d88225.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill enables an AI agent to manage and interact with Tmux, a terminal multiplexer. It allows the agent to create, list, attach to, and control multiple terminal sessions within a single window. The agent can execute commands in these sessions, capture their output, and even automate workflows like running development servers or tests in the background. This is particularly useful for remote work and managing long-running processes.

When to use it

  • Running a development server while performing other tasks on your local machine.
  • Executing automated tests and capturing their output for analysis.
  • Managing multiple services (frontend, backend, database) within separate terminal windows.
  • Keeping background processes running even when you disconnect from a remote server.
  • Automating repetitive tasks that require interacting with the command line.

Key capabilities

  • Creating new Tmux sessions with custom names and working directories.
  • Listing existing Tmux sessions, including detailed information about their windows.
  • Sending commands to specific sessions or windows within a session.
  • Capturing output from terminal panes, including history.
  • Killing individual sessions or the entire Tmux server.
  • Attaching to existing sessions or creating new ones if they don't exist.
  • Managing windows and panes within a session (creating, selecting, killing).

Example prompts

  • "Create a new tmux session named 'devserver' in the /project directory running npm run dev."
  • "List all active tmux sessions."
  • "Capture the last 50 lines of output from the 'tests' tmux session and save them to test-output.txt."

Tips & gotchas

  • Prerequisites: Tmux must be installed on the system where the agent is running (using brew install tmux or apt install tmux).
  • The skill relies on precise command syntax; errors in commands can lead to unexpected behavior.
  • Be mindful of session and window names, as they are used for targeting commands and capturing output.
