Install Obelisk

This is a one-time bootstrap guide. It installs the local Obelisk runtime, then uses that runtime to install the official agent skill from github.com/tommy0103/obelisk-skill.

1. Check for the CLI

command -v obelisk >/dev/null 2>&1 && obelisk --version

If this succeeds, skip to step 3. Do not reinstall a working CLI unless the user asked to upgrade or repair it.

2. Install the CLI

Installing a global command changes the user's machine. Show the command and get the user's approval before running one of these official installation methods.

With npm:

npm install --global @obelisk-apps/cli

On macOS, Linux, or WSL, the official installer performs the same CLI-only installation and never installs an agent skill:

curl -fsSL https://raw.githubusercontent.com/tommy0103/obelisk/main/install.sh | sh

Never use sudo, install a daemon, or download Obelisk from another source.

Verify the result:

obelisk --version

3. Choose the skill installation scope

The standard skills installer defaults to the current project. Before running it, tell the user about that default and ask whether /obelisk should be installed:

• For the current project only — available only in the project where the installer runs.
• Globally — available across the user's projects.

Do not silently choose the current-project default. If the user already stated the scope explicitly, use that choice without asking again.

Run the command that matches the user's answer:

Current project:

obelisk install

Global:

obelisk install --global

Pass through any additional target options the user requested. The command uses the standard skills installer, so follow its prompts instead of copying skill files by hand.

After installation, tell the user to reload their agent if the new /obelisk skill is not discovered immediately. This bootstrap document is not the query skill and must not answer session-history questions itself.
